As I woke up the next morning I felt my cock straining against my shorts. That’s not all it was against. It felt like it was laying perfectly in the crack of her beautiful ass. I feigned like I was still sleeping and gently pushed against her a little harder. To my surprise I felt my sister push back. It stopped there. I could of came if I pushed again.
I laid there a little more and pretended I was waking up. “Hey Dana. You have a class in an hour you better get up.” She grumbled a bit but rolled out of bed and towards her room.
I immediately grabbed my cock and started jerking it under the sheets. I closed my eyes and imagined myself rubbing my hard cock against my sister’s bare ass. I came so quickly I couldn’t believe it. As I was cumming I heard a small gasp near my door. I peered through slitted eyes and saw my sister walking back down the hall. Oh, shit I thought. She saw me jerking my meat. She will probably call my parents and want to move out. To tell the truth I was a little worried.
I didn’t see my sister for the rest of the day until later. She walked into the house and said hi in that cheerful voice she always seemed to have. I returned the greetings.
“Where have you been all day?” She chirped. “Class! And I went a little shopping, and now I am going jogging.” With that she walked to her room and came out a little later with a pair a sweat shorts and a college t-shirt. “I’ll be back in a little bit.” She sped out the door. I had to piss and walked to the bathroom. As I was emptying the old bladder I looked at the window. It was frosted so you were unable to look through it. I flushed the toilet and opened the window a little. Outside was the back of the apartment. It looked onto a little alleyway no bigger than three feet wide to a high wooden fence. I had an idea. I left the window cracked just an inch and went outside and around back. The window was a bit high. I found a cinder block and stood on top of it. I peered into the bathroom. It was great I could see the whole thing. And with the mirror I could see the shower door. I ran and moved my car to a different part of the apartment complex so it appeared I left. I returned to my crow’s nest and stood there another ten minutes before I heard my name being called in the house. I watched Dana walk by the bathroom door several times.
Finally she entered the bathroom to take a shower after her jog. She closed the door behind her. She kicked off her running shoes and then her socks. I knew now that I was going to see her in all her glory. My dick jumped at the thought.
She then took off her shirt. Under it was a sports bra. When she removed her sports bra I almost fainted. There was my sister’s tits. They were much bigger than I thought. She had always worn a sports bra and now I realized they were always confined. Now they were out there for me to watch, but I wanted much more than that. I wanted to suck and fuck them. My dick was now raging hard. I took it out and slowly started moving it back and forth.
