Sister/cougar

When we got back from the trip, Heather wanted to change things a bit in the apartment. I was sleeping on the fold out couch and Heather was sleeping in the bedroom, if you could call it that. It was tiny and the double bed barely fit. She wanted me to start sleeping in bed with her, but I still wasn't comfortable with that. Yes, she was the best fuck I have had, and she could suck like nobodies business, but she was still my sister.

I was still a bit freaked out at how much I liked getting rough with her, and at how much she like me getting rough. I did what I could to avoid looking at her when she showered, yes, she left the bathroom door open. More than once while I was taking a shower or shaving she would come in pull her skirt up, or pants down and sit on the toilet. The bathroom is also very small and there was no way to avoid looking. As I said, to me she is a good looking woman just the right size. So sometimes I would get hard while she was in the bathroom with me

Finally one day I was showering and she stepped in. It is just a shower stall so it was tight. She looked at me and grabbed my head and then brought it down to hers and started kissing me. Her kisses drive me nuts! She held me close, the water from the shower, the feel of her body against mine was erotic, I got as hard as a rock. She reached down and started stroking my cock. I couldn't help myself, I started moaning and really enjoyed the feel.

She turned around, turned the water off and bent forward a bit. Her pussy was right there, so I ran my hand up her leg and into the slit of her pussy. I wasn't sure if it was so wet because of the shower or her own pussy juice. It didn't matter, I ran my finger into her pussy and slid it in and out, when I pulled out I rubbed her clit. She started moaning and stuck her butt out a bit more so I could get full access to her. I rubbed and fingered her a bit, then she turned around and started kissing me again.

I ran my hands up her sides and started rubbing her tits. I started rolling her nipples between my thumb and finger, they were so hard! She whispered in my ear, "squeeze them and pinch them a bit." I thought I was going shoot my load then and there. I started squeezing them a bit, she leaned back and looked me in the eye and said, "stop teasing me, give them a good squeeze." Then she kissed me again.

While she was kissing me I squeezed and twisted her nipples, not very hard, but hard enough to hurt. Heather moaned in satisfaction. I grabbed her shoulders and turned her around, none too gently. She put her hands on the wall and stuck her butt out a bit. I rubbed my cock up and down her pussy, then slid it in. She pushed back so hard I almost lost my balance, but I stayed on my feet and started to slowly slide my cock in and out. She said, "come on, get to it." I smacked her hard on her butt, she let out a little yelp but nothing else.

The shower was too small and I couldn't really get going, so I pulled out and led her out of the shower. I bent her over the sink and slid back in. Now I had room and the floor wasn't slippery. I started pumping hard, I grabbed her hips for better leverage. Then I reached out and grabbed a handful of hair. I gave it a tug back toward me, Heather said, "oh yeah, that's got it." I pumped hard, a couple of times I almost hurt my balls I slammed so hard against her.

It didn't take long before I could feel it building, and I told her. All she said was "oh yeah, I'm ready too." It only took about 10 strokes after that before I started blowing my load. My legs got weak and wobbly, I thought I was going to fall. Her body started shaking and then goosebumps sprung up all over her.

We both "walked" to the bed. We could barely walk our legs were so wobbly. We fell onto the bed and curled up together and fell asleep. When we woke up I knew I couldn't keep away from her. I loved her more than a brother, and wanted her in every way possible.

I told her next time I was going to use her ass, she just smiled.
