Our Best Weeend Ever

It only took a few times for me to wonder whether she was doing it on purpose. It took even fewer for it to arouse me.

Every night for the last two weeks, my mother has finished the dishes, planted a kiss on my cheek, and fashioned herself a steaming bath. Each time, as I make my way down the hall and off to bed, the door is waiting for me ajar--the slit just big enough for my wandering eyes to linger.

The hair on the back of my neck stands up thinking about it now, tucked in, my hand curled around my cock. With every stroke, I recall the smell of lavender, the sound of splashing, and the warmth of steam pouring from the doorway.

I can see her now. She pulls the suds toward her delicious breasts. They protrude from the water like two islands. I want to crawl on my hands and knees to the edge of the tub and latch onto each one--plucking away at her nipples with my tongue.

Then I see her legs stretched out over the sides of the tub, paving a gilded path to her mound. Even from here I can smell her, which forces a groan from my lips. Her fingers trace velvety circles on her pussy. Her silk stomach rises and falls when she gets close.

Before she climaxes, her eyes shoot open and dart to the mirror.

Is she looking for me through the reflection?

I see her eyes move there over and over, but I duck out of the way before she can see me. When I return, I watch her trace her hand around her breasts and down her stomach until she reaches the place that's calling for me. She gasps when she thumbs her throbbing clit.

She arches her head back, forcing my eyes to her beautiful throat. I can't stop thinking about how good it would feel wrapped around my dick, with her tongue lapping at my balls.

The memory is cut short, as I hear the doorknob to my room turning. "Oh fuck" comes out before my idiot brain has time to think of something better.

"Hey little bro," Erin says, "I need to borrow your charger."

Erin stands in the doorway. My older sister--a mirror image of the woman who I was just using to fuel my orgasm.

"Don't you have your own?" I respond, frustrated at the bliss that is currently fading under my sheets.

She cocks her head at me, and then starts to giggle.

"Oh my god. I just realized. Ew, what the fuck?"

In one fell movement I rip the charger from my nightstand and hurl it towards the door.

"'I wasn't doing anything. You're so annoying. Get the fuck out." I say.

I hear Erin giggling all the way down the hall to her own room. I wish I could say that I pulled the sheets over my head and went to sleep, but I didn't. Thoughts of my mother came back as soon as Erin closed her door.

------

The next morning, mom greets me with a hug that lasts a few moments too long. I can feel her breasts pushing into me. I wonder if she can feel my dick begin to harden beneath my boxers? I sit before anyone can notice.

My mother, Ava, is by no means a model. Two weeks ago I hadn't ever thought about her looks. But the more I search her features, the more I realize she has everything I look for in a woman. Her hair is long and dark, perfect for pulling. Her lips are full and soft, perfect for sucking. And her breasts are large enough that she could lay next to me, stroking me gently, without her nipple falling from my mouth.

Erin scrapes the dining chair across the ground, disrupting my train of thought.

"Were you just checking mom out?" She whispers, leaning towards me. I can feel her breath graze the back of my neck.

I cut my head in her direction. "What is wrong with you? Are you, like, a sexual deviant or something?"

Erin, seeing me go red, laughs loud enough for mom to hear.

"What's so funny?" Mom says, working away at the eggs on the stove.

"We--" Erin begins before I interrupt her.

"Erin was just apologizing for walking in on me last night. I didn't have any clothes on."

This time the laughter came from mom. Erin raised her eyebrows at me and tried her own hand at not turning red.

"Well, Erin, did you catch a peep?" Mom said, sending some blood rushing to my groin.

"Eww mom," Erin said.

Mom grabbed two plates and began walking toward us. It was only then that I realized that she was wearing a see-through shirt from work, with no bra underneath. Erin and I watched with our mouths agape as they bounced with each step. I was hard in an instant.

I could feel Erin's eyes wander down to my cock and back to our mother's perfect, natural tits.

The plates clattering on the hardwood table momentarily deflated my hard wood.

"I love you both so much." Mom grabbed Erin by the cheeks and pulled her in for a kiss.

I noticed, after feeling my member aching, that the kiss lingered just a second too long. Just like my hug from before.

"And you, my...good boy." Mom said, before clamping her lips on mine. "I just know that we are all going to have the greatest weekend ever."

The rest of breakfast was uneventful. Mom caught me staring a time or two, but the only thing she did was curl her gorgeous lips into a grin. I even caught Erin looking at her chest. When I noticed her staring, I elbowed her under the table and her cheeks went flush.

I felt all morning like my heart was going to explode. Each look from mom set loose a cage of butterflies in my stomach. I was the first to get up, even though I knew I could knock over the table with my erection.

"I need to go lie down. I'm not feeling my best." I said.

Erin shot up almost immediately after.

"I'm going to my room also, I have homework to do."

Mom made a pouty face that would have looked perfect plastered with my cum.

"You two are no fun." She said. "I was hoping we could spend some family time together."

"Maybe later." I said, practically running down the hall and into my room.

I heard Erin's footsteps follow quickly behind me.

"If anyone needs me, I'll be in the bath." Mom said.

------

My dick ached in my hand. I had been tugging on it for almost twenty minutes when I heard the water running. Images of my mother swirled around in my imagination. I pumped up and down on my shaft, thinking about pulling her panties to the side, fucking her in front of a rapt audience, and even sharing her with another woman.

But it wasn't enough, not when I knew that she was just one hallway from my room. She was practically inviting me to take another look at her body.

I swept the covers away and strode to the door. The door to my disheveled room creaked a little, so I paused to make sure that no one had heard me. Just like I suspected, the door was ajar again. This time, however, it was damn-near open. With each step, I could hear something.

Mom was moaning. Each utterance made me take a step and forced the blood rushing to my shaft. I got to the doorway and angled myself so I could see her reflection in the mirror. She was practically punishing her clit. Each stroke of her thumb and forefinger sent water careening over the edge of the tub.

Without thinking, I took my dick out of my shorts and plopped it into my hand. I stroked slowly, enraptured by the sight of her tits and the sounds of her desperation. I wanted to kick the door open and tear her apart.

I heard her voice sink to a whisper. I leaned my head in close to hear. She was saying something short, something impossible.

She was saying my name.

"Ethan. Baby boy, I need that cock in mommy's pussy. I want you to fill me up baby. Make mommy a mommy again."

I had never been more turned on than watching her do that for the first time. My mother, who I once thought was as saintly as they come, was bringing herself to orgasm thinking about her son. I closed my eyes and my stroking grew faster--until I thought I was going to burst.

Then I felt something new. A hand reached down and grabbed my cock. My mother had somehow crept out of the tub and was laying claim to her new fuck toy. But still I heard the water splashing. When I opened my eyes, my mother was still there thumbing her clit for me.

The only thing left to do was turn my head. Erin was there, one hand brought up to her lips in a shushing gesture. She leaned towards my ear. It was only then that I saw her clearly. Her perky, full breasts peaked out of her tank top. Her ass hung out of her boy shorts. She was a younger image of my mother and I desperately wanted her to continue stroking me forever.

"You like watching mom, huh? You're so fucking hard, little brother." Erin said.

I was so fucking hard. I hardly thought of my mom in a sexual way before, much less my older sister. But here she was stroking me slow, making my cock twitch in agony.

"I can hear her saying your name. God, did you see her fucking tits this morning? I had to run to my room and make myself cum. Looks like you weren't as successful?" She whispered.

All I could do was shake my head.

"Let your sissy help." Erin released my shaft and placed her hands on my shoulders, keeping me in place. She moved to my front. We locked eyes for what seemed like an eternity--until she put her hair up and slowly sank down to her knees.

"Keep watching mom." She mouthed, before kissing the tip of my cock. I did my best to keep my eyes on mom writhing in the bathtub, but my sister's talented mouth provided a strong distraction. Erin rolled her tongue around my glans, forcing a groan from my lips.

The splashing stopped for a minute. Erin and I froze like animals. I held my breath and Erin held her tongue for a moment, until we heard the splashing begin again.

Erin looked up and mouthed, "Close one. Be quiet, little bro."

She sank her lips further down my throbbing penis, circling her tongue the entire time. I had been blown before, but her tongue was like magic. Erin sank until I hit the back of her throat. She did her best to suppress her gag reflex, but I welcomed the resulting surge of saliva.

I watched her bob up and down. Erin must have read my mind, because she quickly pulled her tank top over her perky breasts.

"Not as big as mom's, but you don't seem to mind." She said.

"I can't believe this is happening." I said.

"Me too. But since I saw how hard you were for mom this morning, I haven't stopped thinking about if you could ever feel the same way for me."

I couldn't take it any more. I gripped Erin's tight ponytail with one hand and began fucking her throat. If it weren't for mom furiously rubbing her pussy, she would have heard the gulping sound that came with each of my thrusts.

Erin dug her fingers into the flesh of my ass so hard I thought she might draw blood, but I was too distracted by her divine suction to check. It must have only been a minute or two before I was at my peak.

I struggled to whisper, "Erin, I'm going to.."

"Cum in my mouth. You taste so good, baby." She said.

"You really are a fucking deviant, aren't you?" I said.

Erin responded by taking all of me. I could feel her throat quivering. I looked down and could see the tears beginning at the corners of her eyes. I shot rope after rope of my seed down my sister's throat, and I knew that other women were ruined for me.

She looked up at me and opened her mouth to show it was empty.

"Pretty sweet, especially for someone so sour." Erin kept stroking my sensitive tip, causing my knees to buckle.

I helped her up to her feet and couldn't resist the urge to kiss her. I drew her into me, plunging my hands down her shorts to grab her ass. Our tongues explored each other's mouths so intimately we didn't hear the water stop.

Erin pulled away from my kiss, noticing that my cock was already hard again.

"I want to feel you inside me. Your cock would fit my pussy perfectly."

"I love you sis. The only thing I want to do is make you cum." I said.

The bathroom door swung open to reveal our mother, clad in a bathrobe--water droplets trickling down her cleavage.

"Well now, I hope you two don't mind an audience." She said, cutting us a playful smile.
