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.
