I left her house and later returned to get something I forgot. I will never forget what I saw.
We had been at her house for the football game. We lost and myself and everyone else quickly seemed to leave. I got home, realized I forgot my cheque book. I went back over there and I have always been able to just come on in whenever. So I went to the downstairs living room only to find her nude and masturbating.
I just said, 'oops'. She got up and wrapped a blanket around herself. I told her not to be embarrassed. She was obviously embarrassed but yet still quite horny. I smiled and said, 'can I join you'. She said 'Oh hell yeah...' Then she dropped her blanket, lay back on the couch and started again. She then made me stand right over her face. I unzipped and pulled out my hard-on (Sorry, my cousin has an awesome body!) and stroked.
She reached up and gave me a couple of strokes. She started to cum and then I did. All over her boobs, cum all over! I loved it. She said next time she is just going to watch me do it. I will likely be over there tommorrow!! I love jacking off so much, three times yesterday and once on her tits today.
