Finding pictures of my sister. It happened.

I can’t believe what happened on the first day I visited my sister and brother in law. After a good lunch and a tour of Tony’s University, which I think I might apply to, everything went crazy after that. Granted, I was coming here hoping to fuck my sister but I never thought of her husband being around.

He put on a dirty movie that my parents wouldn’t let me watch. Sitting with my sister, who didn’t have a bra on, didn’t help. I was cold so I took some of the big blanket Susan was using. I was hard from the movie and when she touched me, I nearly yelped out. Her hand went up my pants and grabbed my dick, I thought I was going to cum. Somehow, I didn’t cum as she slowly stroked me. When a nude scene came on, I knew i was going to blow, Susan must have figured the same thing and stopped stroking me. After the scene, I needed to get away and cum.

I thought I could rub one out quickly but Susan was close behind me. She caught me with my dick in my hand. She moved so close, my precum got on her shirt. She took her shirt off and her large boobs were right there. I almost came when she squatted down and her tits rubbed my dick.

She put me in her mouth without warning. It was a moment I had been thinking about ever since I saw her nude pictures. My orgasm came so quickly, I couldn’t warn her. She swallowed most of it and got what came out of her with her fingers. She quickly left after that.

I wasn’t in the bathroom a minute and my sister blew me and swallowed my load. I sat on the toilet, catching my breath and processing what had happened. After a piss, I got another slice of pizza and went back to the movie. Tony gave me a funny look as I sat by Susan. She ignored me, I assumed not to give anything away from our encounter. After the movie, I went straight to bed.

I got up early and went for a run to clear my head. I didn’t sleep well. I kept thinking of what happened and what I hope happens.

I went out the side door, where the laundry room is, so I went back in that way. Susan was there, moving clothes from the washer to the dryer. She was bent over with her thick ass facing me. My mind went numb and my dick took over.

I put one hand on her back and one on her ass. She jumped and stood upright. My hands quickly went up her shirt to her big boobs.

“Where’s Tony,” I growled into her ear.

“He’s still in bed. Hurry. I don’t care if it’s quick. Fuck me and cum inside me.”

She pulled her shorts down as quickly as I pulled mine down. She put her hands on the dryer and stuck her thick ass out. I guided my hard cock to her opening and pushed all in. She grabbed a towel and screamed into it as my thighs hit her ass.

I grabbed her hips and was about to take her to pound town but she started backing into me. Looking down and seeing her thick ass smacking into me and seeing my dick going in and out of her was too much for me. I grabbed her hips, pushed in as deep as I could and unloaded what felt like the largest load of my life.

After I pulled out, she quickly put her shorts back on and continued to do the laundry like nothing ever happened. She told me to go shower and get ready for breakfast soon. I could see my cum running down her legs as I walked away.

I was still hard in the shower, thinking of how I just fucked my sister. It was good but over too quickly. I was hoping the first time would last for hours but I should have known that wasn’t going to happen with her husband home.

During breakfast, I told my brother in law that I might want to attend his university. He was excited and told me he’d drive there and get me an application. (Remember, 1980s). He told me to stay at home and spend some time with my sister and would only be gone an hour or two.

As soon as his car pulled away, Susan practically drug me into their bedroom. She undressed quicker than I could. She got onto the bed with legs spread open. I wanted to fuck her again but I wanted to taste her first. I went face first into her pussy. She grabbed my head and was squirming all over my face. Within a couple of minutes, she came on my face.

She told me to lay down and climbed on top. She guided my rock hard dick into her opening and lowered herself. My hands were fondling her large breasts as she aggressively bounced on me. I only lasted a few minutes before I came inside her again.

I knew I could go again so when she rolled off of me, I got her on her hands and knees and moved behind her. I could see my cum dripping out when I pushed back in. I grabbed her generous hips and started smacking my thighs against her ass. I went hard and fast. Her boobs we swaying with the rythem I was setting. She came two times before I came again. We both fell exhausted onto the bed.

We layed there a few minutes before the phone rang, it was Tony. He said he was leaving his office and was going to stop and get some food. We knew we had another hour before he got home. We ended up fucking all over her bedroom until I came in her mouth.

After we both showered, we sat and i remembered there was something I needed to tell her.

“A few days after you left, I was looking through your pictures and found an old box of dad’s. I looked inside and found a nude picture of mom. It looked a lot like you and before I knew it, I was jacking off. Mom caught me and we ended up having sex in the basement. I hope you’re not mad at me?”

She let out a nervous laugh and sigh of relief. She definitely didn’t look mad but nervous for what she was about to say.

“No, I’m not mad. I’m not really surprised after you heard the truth. Now, I have a secret that may shock you. Dad took my virginity when I was 18. I was nervous about going to the prom and having sex. Mom wasn’t home so I talked to dad. We had a good talk and one thing let to another and we had sex. He didn’t force himself on me. I probably wanted it more than he did. He took his time and was gentle and loving to me. It only happened that one time and we never felt awkward or horny around each other. What do you think about that?”

It was awkward news but I wasn’t mad. In fact, my dick was hard again and she noticed. She got on her knees, pulled my dick out and blew my until I came in her mouth. A few minutes later, he husband came home.

I filled out the papers to apply to the university and Tony took them back on Monday. I left for home Sunday afternoon with nothing happening between Susan and I. A couple of weeks later, I got an acceptance letter from the university. I called Susan to tell her. I then heard her tell Tony and he said something that made my cock twitch.

“That’s wonderful news. He should live with us. I would save him and his parents a ton of money.”

At the same time, both my sister and I went, “YES.”
