My big sister Tanya is really sexy, and I lusted her every day for years. The problem was she had no interest in me or my friends at all. I'm 18 and Tonya is 20 now, I know she's not a virgin anymore, but I didn't care about that. I've heard her getting screwed many times as we share a very thin bedroom wall. She would often have boyfriends over when mom and dad were out or asleep. She sounded so seductive and hot having sex in her room, I loved hearing her climax more than anything. I loved it so much I started imagining myself having sex with her as I jacked off just a few feet away on the other side of the wall. I would hold off on my load until she screamed in orgasm. It wasn't easy, but it was hotter and more explosive that way.
I really wanted to feel her pussy gripping my cock and making those noises for me. I was shy around girls, and never had a steady girlfriend before. Worst of all, I was still a virgin. I had kissed a few girls and felt their boobs but that was it. I never had any pussy at all, or even touched one. Now, I was constantly horny and ready to burst if I didn't get some kind of sexual action soon. Also, my sister had not had a boyfriend over in a few months, so I had not heard her sex noises in a long time either. I needed something soon I didn't know what to do. I was too shy to ask out any girl I knew and jacking off wasn't satisfying me enough anymore.
I began to spy on Tonya more and tried to see her naked or in panties around the house, I didn't have much luck. I saw her by the pool a few times and sat with her a while, she noticed me looking a lot and didn't seem so happy with my prying eyes. She locked the bathroom door when she showered and kept her bedroom door shut most of the time. Then I got an idea, I could peek in her window and maybe see her naked that way.
So, one day when nobody was home, I made a little path through the bushes and set up a milk crate so I could see in her room perfectly. The bushes were thick behind me so I wouldn't be seen. Her blinds had cracks where you could see though them even if they were shut, it was a pretty good set up. I was about to see more than I ever imagined.
I began to peek in her room in the mornings and hit pay dirt. I got to see her sexy naked body up close many times. Her pussy was clean shaven, and I loved watching her put on her panties or thongs. She was putting on quite a hot show for me several times a week and had no idea. Then I began to peek inside her room through the window late at night and saw more than I expected. She didn't have a boyfriend at the moment and her BFF Katie was spending a lot of nights over the house recently. Katie was cute and sexy, and 19. She didn't go to my school, so I didn't know her very well. I did find her hot and sexy, like my sister.
My parents went out for the night, and I told my sister I was going to stay over a friend's house. Then I took off and snuck back a few hours later. It was dark outside, and Tanya was in her bedroom with Katie. I quietly crept up to her window with my phone recording the video. I heard music playing as I stepped up on the crate. When I peeked in the dimly lit room, I was shocked and turned on instantly by what I saw.
Tonya's and Katie were 69ing on her bed. I nervously recorded them, as my hands were shaking with excitement. This was the hottest thing I had ever seen in person. My cock was hard as ever, as I watched the free sex show. The girls were licking and touching each other's pussies with deviant pleasure. Tonya was on top of cute Katie, and I could see Katie's pussy perfectly because it was facing the window. I watched them for about 15 minutes and enjoyed every second. I had enough video footage and snuck inside the house. Then I got the nerve to bust in on Tonya and Katie. So, I did. I turned her door handle and ran in.
"Are you Ok Tonya" I said as I entered her room quickly.
"Oh my God, what are you doing in here Mark?" Tonya yelled out between Katie's legs.
"I thought you were in pain." I stated.
"Get out of here Mark." She yelled out with anger.
I went to my room and listened through the wall. They were obviously embarrassed and worried. I decided to get outta there quickly. I gathered a few things and prepared to leave for the night. I knocked on Tonya's door before I left to say goodbye.
"Hey, I'm sorry you guys. I'm going to Tom's for the night. I'll see you tomorrow, Tonya. Take care Katie." I said and left.
"Ok, Thank you Mark." I heard Tonya say without enthusiasm, as I walked off.
I went to hang out with my old friend Tom. Tom is a smart guy and he got me thinking about what I could do. I didn't tell him exactly what I saw my sister doing, but I did mention my sister is wild. He knew that and about her sexy noises. We talked about girls and sex a lot and then we tried to get some sleep. Tom isn't a virgin and had some good points to make.
The next day when I got home from Tom's house, mom and dad were home, but Tonya was nowhere to be found. When I did see her again that night, she was acting very shy and bashful. I was pleasant and didn't say much. She warmed up to me over the next few days and I made slightly suggestive comments about her outfits. She took them nicely and gave me confidence to move forward. I had this over her and Katie according to Tom, so I decided to use it to my advantage.
A few days later mom and dad were gone, and I caught Tonya in the kitchen eating alone. She was in a good mood, and I was horny as always. I felt it was the right time for us to talk about her eating Katie's pussy and vice versa.
"Tonya, are you Ok?'
"Yes."
"You've been acting distant." I pushed.
"I can't believe you saw us doing that." She said embarrassingly.
"It was hot, sis."
"What? I don't normally do that ya know." She protested.
"It was a major turn on. You guys looked hot doing a 69." I said nicely.
"Glad you think so." She said without enthusiasm.
"Do you think mom and dad would approve?" I asked.
"No. Why would you ask that?" She said, surprised.
"Because I want to have sex with you or Katie, or I will tell mom a dad what I saw you girls doing."
"Mark, you are absurd. No way!" She said in shock.
"I have proof."
"Nuh uh." She said with a surprise smile.
"You wanna see?" I teased.
"I don't believe you." She said now looking upset.
I showed her some of the footage I had on my phone. She was shocked and mad. She tried to take my phone from me, so I held on tight. Then we rustled around the house and ended up near the family room sofa. I am much stronger and ended up on top of her on the sofa, I pinned her down and got in her face.
"We are going to have sex, or I will show that video to daddy." I teased.
"You are serious, aren't you?" She said sadly.
"Yes, I am!" I said forcefully.
"Maybe I can get Katie to do something, she's single now. That's why we were just messing around." Tonya said trying to make light of the situation.
"Katie would be nice, but I want you more sis!" I said boldly.
"Are you insane, what has gotten into you Mark? We can't do that! I'll get Katie too do it." She pleaded.
"Ok call her now!" I said firmly.
Tonya smiled and called Katie. They argued and Tonya realized she was stuck with me. I was glad.
"So, Katie is a, no?" I said with a smile.
"Yeah, Mark this is weird." She said pissed off and disgusted.
"I don't care, I think your hot and I want to have sex with you Tonya. I promise I will never tell mom and dad anything." I protested nicely.
"This is wrong Mark; don't you know that?" She said upset.
"So is eating pussy when you are a girl." I said sternly.
"I know." She agreed sadly.
"Which is worse, sex with your brother or sex with a girl?"
"I don't know Mark." She said confused and looking down.
"I think sex with a girl is worse, so let's get this over with." I said sternly.
She reluctantly let me pull her down the hall to my room. When we stepped in, I shut the door and locked it.
"Can't we figure something else out?" She begged as she looked around.
"No way sis, now start undressing." I said very firmly.
"Oh my God, I hate you." Was all she said.
Tonya reluctantly removed her top and shorts and shoes. She looked so upset and mad. She also looked cute and sexy with pouty lips.
"Are you happy?" She pleaded.
"Keep going." I pushed.
"You first, you little perv." She said with frustration.
I pulled off my shirt shoes and shorts. Then I pulled down my underwear exposing my big hardon.
"Oh my god." She said as she saw my cock. She put her hand over her mouth in awe and smiled.
"Now your turn Tonya."
She did as she was asked and removed her bra and let her tit's out. They looked perky and sexy as always. She kept looking at my cock as she pulled off her panties for me. She stood covering her boobs and pussy the best she could.
"Now come here Tonya." I demanded.
She came up to me and grabbed my cock and squeezed it hard. She seemed to be a little turned on by all this naughtiness. No girl had ever gabbed my cock before, it felt great.
"Is this what you want, you little perv?" She said with a naughty grin, obviously giving in now completely.
"Yes, and this." I said as stuck my finger near her cunt lips. Then I slid my finger in and felt her insides. It was moist and hot; I licked my finger so she could see me taste her.
She gave me an awkward look and spoke. "You really want to fuck me, don't you?"
"Yes, really badly." I said honestly.
"Can I just blow you?" She pleaded.
"Sure, why not."
"Thank you!" She said with a sexy smile.
Tonya went down on me and began to get my cock wet with her saliva. I know she had done this before. She seemed to get into it and began sucking the sides and bobbing on me, as she jacked me. Soon she was giving me her best, sucking and surrendering to my manhood. She sucked and began to show signs of lust and passion. I think she tried to forget it was my cock she was sucking on. She looked like a porn star in action, she knew what she was doing...
She continued to suck me and jack me with real lust and passion, it felt wonderful. I shook and she knew what was coming. I was surprised that Tonya initially swallowed some of it and let the rest drip off her chin. She looked so sexy with cum on her chin, I was blown away. My sister was the first girl to give me an orgasm. It was delightful, to say the least.
Tonya stood up and wiped her chin and gave me a funny look and got dressed. She left quickly and didn't say anything. I think she enjoyed that, I certainly did. Mom and dad came home shortly after, and we all had dinner together. I often gave Tonya nice smiles, which she frowned on. She avoided me the rest of the night.
