Something in the Tea

All people involved in this story are 18 years or older.

Don't you dare stop, don't you dare. You know where you have to cum, you have to cum in me baby.

My mind was reeling from the absolute ecstasy I was in, I was balls deep in my sister's pussy and I knew she was right. I had to cum in her. I had no choice really than to put my seed in her belly. I was on the verge of the best orgasm of my life, and it was because I was coming in my beautiful sister.

48 hours previously Friday Night

Y'all be good and no boys or girls over while we're gone. We'll be back Monday night.

My dad knew I didn't have a girl to come over when he said that. It was just a cheap shot. Our parents were headed out of town for a long weekend leaving me and my sister home alone. I'm a senior in Highschool. My name's Josh and my sister Amber are Irish twins. Only 11 months apart she was living at home while going to the local community college. She came downstairs to see what I was up to. We were pretty close growing up, even when she was still in HS with me. I told her dad said no boys over and she gave me a push.

I'm working on that she said with a grin.

Who I asked?

Amber was pretty, just shy. She always wore large baggy clothing, but my friends had seen her in her bathing suit and could vouch for her body. She had D size breast. A little fat around her tummy and a round ass. Hey, I'm a teenage boy. I'm going to notice a body. I just don't dwell on my sisters.

A boy from class she said.

My shy big sister is finally going to get a boyfriend I asked.

I don't want to talk about that with you, she said as we sat down to watch something on the TV. Around 10:00 I said I was going up. She told me to have some tea with her before I went to bed.

I don't want caffeine before bed.

It's an herbal mix don't worry, and she left for the kitchen.

She came back from the kitchen with two cups. I really wasn't a night tea or coffee person but figured an herbal tea would be fine. It tasted okay and we chatted a bit while we finished, and I went up to bed. I heard her bedroom door shut not long after me.

Lying in bed I started to get horny. Nothing unusual there, I was an eighteen-year-old teenage boy. I thought about going over to my computer or grabbing my phone to look at a porn. Instead, something inside of me said to use my imagination. Why not it had pulled me across the finish line many a time. I grabbed the lotion and a shirt to catch my cum. Laid on my back and started stroking. Nothing seemed to be getting me hard and then a memory of my sister in her bathing suit flashed and I was stiff. My hand just happy to feel me hard started stroking. Why was I picturing Amber, her breast almost spilling out of her top? Damn I was hard and confused.

Catching her naked coming out the shower flashed. What if she let me play with those boobs. I was stroking my cock to images of my sister's beautiful breast. I thought about them in my face, my mouth on them. Then it happened so quick. I had to most intense orgasm of my life. My cum overshot the shirt meant to catch it and my hot spunk landed on my chin, then rope after rope landed on my chest, then down to my belly button to just dribbling down to the base of my cock. Holy shit that was the best orgasm I had ever had. Truthfully the only orgasms I had ever experienced were from jerking it. However, none of those had ever come as close to what I had just experienced. I cleaned myself up the best I could. As I was drifting to sleep, I thought I could hear my sister moaning in her room.

Saturday Morning

I woke up the next morning completely refreshed. I couldn't stop thinking about how good that orgasm felt. I needed that again. But first some breakfast. I went down to grab a bowl of cereal. Amber came down in nothing but an overly large t-shirt and panties. I noticed I could see her nipples were hard. She must have caught my glance of her breast.

Look she said I need to know if you jerked off last night.

Wow that was embarrassing. What no sis. I tried lying.

No she said sounding almost scared I really need to know.

Shamedly I hung my head and admitted I had. Was I that loud, I asked?

No, the scared sound not going away.

There's this boy at school I've been trying to get to like me. I know he noticed me, but he's shy like me. I wanted to give him some encouragement. So, I was reading some occult stuff online and found a recipe for this potion. I wanted him and me to take it. I thought I needed to try it out first with someone with no attraction, just to see if it had any effects and I didn't think it would work on my own brother. You're supposed to give it in doses. Each dose makes the bond stronger and stronger until your inseparable soul mates after the fourth dose. Before that the effects can fade. I thought with the first dose would maybe just make you less of a butthead. Both partners have to take it for it to work. When I went to bed, I got just so horny and a memory of me hearing you jerk off flashed in my mind and got me wet and my hands had minds of their own. One hand slipped to my pussy, and another grabbed my breast. Then I had the longest most intense orgasm of my life I basically blacked out till morning.

My jaw was dropped.

So when you jerked off last night did you think of me she asked?

How could you I yelled. I'm your brother and you made me jerk off to thinking about your breast? What the fuck is wrong with you Amber? She started sobbing saying she was sorry; she didn't think it would be that potent. She didn't want to think of me like that either. For all my anger I couldn't help but want to console her. I pulled her in for a tight hug telling her it was okay. It was a mistake.

She buried her face into my shoulder as she stopped crying. But in holding her tight her breast were pushed int my chest. I couldn't help it. My cock started firming up. I tried to back away, but she pulled me closer and her chest was back to pressing against me. My cock was at full attention, and I knew she had to feel lit against her by now. She wiggled a bit which made my cock twitch.

Is that the potion in your pocket or are you just happy to see me she whispered into my ear?

It has to be the potion, I said.

Was your orgasm intense last night Josh?

I couldn't lie. I told her it was the best of my life. I had intended to just eat a quick breakfast and go back upstairs to recapture it before her confession. My cock was staying hard against my sister's body as I thought about jerking to her. Since it was the potion, I don't know if I'll get that again. My sister started grinding against me now.

What if we could have it one more time, she asked? It was so powerful I need it again.

No that's not right, I said. I'm hard but I don't want to jerk off to you Amber. She broke the embrace and went to a cupboard. She pulled out what must have been the potion and portioned some into two glasses and handed me one.

I don't really want to get off on thinking about you either Josh, but I need to cum like that again. Look as long as we don't take all 4 doses we can have that orgasm again. Itss just the potion Josh. We're not really committing incest if a potion is making us think these things, is it? I wanted her to be right, and I knew, like her I needed to cum like that again.

Okay I said downing my potion. She gave me a kiss on the cheek and swallowed hers. Alright I better get up to my bedroom before I start rubbing one out right here. Agreed she said. I followed her up the stairs staring at her ass and panties. I jokingly said I'd see her at dinner since I was prepared to pass out again once I finished.

I got naked, grabbed some lotion and laid on my bed. I began to picture my sisters breast. My cock was as hard as it ever been. I thought about my sister's ass as we were coming up the stairs. I was beating my meat to her sexy ass. I let the images in my mind go further. I wanted to see my sister's pussy. I wanted to make out with her I wanted more than just feeling her, I was so close to cumming but unlike last night I couldn't get there. I was beginning to grow frustrated when my sister almost broke down the door. Naked she just said mover over and got on the bed with me. I didn't have time to admire her form before her nakedness was rubbing against me. She took my face in her hands and brought my face to hers. We kissed, but not a peck her tongue forced its way into my mouth as my mind was reeling, she took my hand it put it on her breast. She broke the kiss.

I couldn't cum she said. I knew I had to come over.

Amber this isn't right we were just supposed to jerk off thinking about each other.

Just let the potion do its thing baby. Here situp. We both sat up against the headboard, our naked bodies seated next to each other our heads turned facing trying to keep our kiss. She was stroking my cock now and I reached over to touch her sex. She gasped as I started to rub her clit. You're so wet Amber.

And you're so hard. Say it Josh, say you're hard from your sister stroking your cock.

I'm so hard from my sister stroking my cock I managed. Oh god Amber I'm about to cum.

Aim for my tits baby I want you too cum on my tits.

I felt her thighs tighten around my hand.

Oh god Josh, you're making me cum I'm cumming on your hand.

With that I groaned and shot a hot thick sticky stream all over my sisters' perfect tits. Rope after rope found their mark as Amber finally put a hand on my hand. What was that I said looking into her eyes. I thought last night was the best orgasm of my life, but wow this was so much better.

It was the potion Josh; it made us escalate and get physical. I figured it out when I couldn't get off just thinking about you, and started thinking about touching you, and you touching me. It got better but I still couldn't cum. I knew you had to be the one to get me off. She then surprised me by wiping some of my cum off her tits and tasted it. It was so sexy. Something in my head told me I had to taste her juices on my hand. It was right, she tasted like heaven. I grabbed a towel and cleaned us up the best we could. I felt myself crashing. I got to crash Amber I'd like it if you stayed. Of course I'd love to snuggle with my little brother.

Saturday Night

It felt comfortable having her naked body against me, but I was exhausted. We both slept till almost dinner. Waking up naked next Amber was a little awkward. I kept picturing her how she was several hours ago. Sex starved, jerking me off and me cumming on her tits.

I'm hungry, she said. Let's get some dinner.

We went downstairs. Amber in just her t-shirt leaving her panties off. Me in just my boxers. I ordered a pizza. We talked on the couch while we waited. Amber I thought last night my orgasm was the best I could ever have, but what you did to me this morning.

Easy Cowboy the potion did that to you. And it did that to me.

I don't know how I never noticed your body before.

Because you're my brother duh she said snarkily.

The doorbell rang and the pizzaman left it at the door. It broke the tension, and we didn't say much as we ate. Once we finished, I told her we should try to watch some TV and she agreed.

We sat down on the couch. No matter what I put on I couldn't get the images of Amber out of my head. I wondered if she was thinking the same thing. She said it was just the potion, but I was sitting here hours from having cum all over her tits in the best orgasm I had ever had. Suddenly she spoke.

I can't stand it. I have to have one of those orgasms again.

My cock immediately shot through by boxers. Looks like you do to baby brother. Amber I can't.

You said if we took all the potion we'd be stuck together.

I didn't say we take it all baby brother, but just one more dose. We get each other off in a massive orgasm and sleep it off. Tomorrow morning I'll go spend the day with a friend and everything wears off. It's not incest if it's the potion remember.

Amber, I'm already thinking about sucking on your breast and rubbing your pussy again. I shouldn't be thinking about my sister like this, and I don't think it's the potion. She blushed. I know it's wrong, but I need this Josh. Please just one more time. She took her shirt off showing me her naked body. God she was beautiful. I want to hold your cock again I want to make you cum Josh. I can see you want too as my cock betrayed me. She went to the kitchen and came back and handed me a glass.

One more time I said, we'll get each other off and sleep it off tomorrow?

Yes and she downed hers. She seductively walked over to me and tilted the cup to my mouth. I swallowed. I followed her naked ass up the stairs. I could tell the potion was already working. I was admiring my sister's ass and I could tell her pussy was getting wet. We went back to my bedroom and begin making out. Her lips tasted sweet. Our hands explored our bodies. I broke our kiss and moved my head to her breast. The first breast I ever touched. I couldn't believe anything could be so soft, or feel so good. The sense of horniness seemed to have changed. The last two times felt like a mad rush to orgasm. This time I still had the fire, but it seemed to be building slower. Like the potion wanted us to take our time.

You have the most amazing tits Amber. She moaned as I took a nipple into her mouth. Ambers hand found my cock at the same time mine found her pussy. I kept sucking on her tits as I could feel my orgasm build. And then it stopped. Like her this morning I knew what had to be done. I knew. I wanted this. The potion escalated again. I moved my head down between her legs. In her haze Amber spread her legs for me. Our bodies were in control not our minds as I breathed in my sister's sex. She ran her hands through my hair. I admired her beautifully soaking wet pussy and slid my tongue along her slit. Her whole body shuddered as I tasted my sister. My face was in her snatch and it was the best place in the world.

Oh my God Josh what are you doing to me.

I reached up and grabbed a breast and then twisted a nipple as I kept up my assault on her pussy. Her moans grew louder when I moved up to her clit. As I started my final assault she began to gyrate her hips, humping my face when suddenly her thighs gripped my head as her whole body stiffened. She let out my name as she came for what felt like forever.

I was hoping she wouldn't immediately crash as I was still rock hard. Instead she pulled me up to her and kissed me deeply while rolling me over onto my back.

My turn she said with a grin as she swallowed my cock.

I had seen this in porn, but nothing could prepare me for it. Her tongue and lips and warm mouth massaged my cock in the most loving way possible. You're incredible Amber I said as she bobbed her head up and down my member. I knew I wasn't going to last long. I'm going to come soon Amber and I tried to sit up so I could cum on her its again but she gently pushed me back down and quickened the pace to send me over the edge. I warned her one last time that I was cumming. Then the first shot hit the back of her throat. Oh my God again I was having the best orgasm of my life as my sister sucked the cum from my cock. She swallowed as much as she could before aiming my last couple of shots at her tits. She collapsed on me, and I could feel the cum from her tits smear on my leg. You were incredible, I whispered as she slid up and kissed me deeply. Our mouths were just a collection of our sex at this point. I ran my hand through her hair. Neither one of us had to say anything as we fell asleep on top of each other naked.

Sunday Morning

I woke up in my bed alone Sunday morning. I was sad to not wake up to Amber. The images of last night filled my thoughts. Her breast in my face, eating her pussy, her sucking my cock and swallowing my cum as I had the most incredible orgasm in my life. I wondered how I could ever move past that. This was dangerous. We couldn't take another dose or we'd be damned together. I went downstairs hoping to find Amber. Instead, I found a note. Josh, As promised I've left so things can cool off. Enjoy the day, love Amber.

How could I enjoy the day without my sister? She was right though. We had to let the effects fade. I figured I'd try and play some video games. That lasted a couple hours but I was still restless. Images of Ambers tits and pussy kept invading my thoughts. Finally, I decided I would jerk it to some porn. I saw a sexy thumbnail but the title was siblings finally fuck. Ehh it's made up I thought. I lubed up jerked my meat to this beautiful girl try to convince her brother to cum inside her but couldn't finish even though the girl was stunning. I just couldn't cum. I went for a walk. A cold shower, but I couldn't shake the last orgasm I had.

Sunday Night

Before I knew it was night. I was eating some left-over pizza at the kitchen table when Amber walked in. She was stunning. She came to me crying. Again, I hugged her.

Josh I'm so sorry I shouldn't be here.

What do you mean Amber?

You know what I mean. You can't tell me you haven't been thinking of us all day?

I have I said as my cock started growing. We can't take the last dose, no matter how much I want to. We can't be soulmates I'm so worried every time we've taken it, its escalated and theirs nothing left after my brother ate my pussy, nothing left but him fucking me she said crying.

I tried to console her. We should never have taken it this far, I said.

She cried as she said I know.

We just have to let the effects fade. How about I leave for a while I said?

We can't have sex Josh, I'm not on any pill, I can't get pregnant by my brother.

Shh shh I said trying to console my sister.

But that orgasm. Imagine how good it would feel?

Amber I know it would be the best orgasm of my life. Each one has been better than the last. I know but we can't, we'd be damned we can't have sex no matter how good it would feel.

I kept her tight, but my cock was pushing into her. She broke away and went to the cabinet. She swigged a dose. Amber, what have you done, I asked, starting to cry myself.

I did it Josh. I need this too much. I need you too much.

Amber, I can't, I said crying as she handed me the last dose. Please Josh Please I need this. Crying I tipped the bottle up. And that was that. We were both done crying.

Amber took my hand, but didn't lead me upstairs. She guided me to our parents' bedroom. I want to consummate my love for my brother on the bed we were conceived in. I just took her face and kissed her deeply. The burn seemed even slower than last. We both knew where were going but weren't in no rush to get there. I helped her take her shirt off first and unhooked her bra freeing her breast.

My brother likes my breasts, don't you Josh. I love your breasts Amber. I took a nipple into my mouth.

These breasts are your breasts now little brother. Let them always give you pleasure baby. I was enraptured moving from one breast to another. I claimed each one with my mouth. I laid her down on the bed and took her shoes and socks off. Then her pants. Finally, I took a second to admire her body naked except for her panties. Then I moved to slide them down. My sister helped me gain access to her sex by lifting her hips up as I pulled off the last of her clothes. I stripped myself standing naked of the bed of my wanting sister. I climbed on to the bed with her.

Feel how hard you've made me Amber. Feel how hard I am for you. Amber stroked my cock teasing some precum from me.

Lay down Josh.

I did I was told as she swung a leg over me and straddled me. She dragged her slit down my shaft and smiled.

See how wet you make me. God she was incredible. We kissed some more and then it was time. We both knew it. We both wanted it. She picked her hips enough for my shaft to point up. I could feel the tip of my cock at her hole. We looked into each other's eyes as she impaled herself on my dick. It was the greatest pleasure of my life. Neither one of us moved as we took in what we had done. Looking into my sisters' eyes with my cock buried in her pussy I told her I loved her. I love you too she said. She started riding me and what I thought couldn't get better just kept getting better. Your pussy feels so good.
