Later that day I still can't get my mind off what had happened earlier...outside rubbing oil all over my sisters tits and ass. What was happening? I mean in the last few years she has really developed into a beautiful woman, I've seen it happening the whole time but never really noticed till now. After dinner I retire to my room, with the ideas still fresh in my head I think I'll just rub this one out and call it a night.

Later that day I still can't get my mind off what had happened earlier...outside rubbing oil all over my sisters tits and ass. What was happening? I mean in the last few years she has really developed into a beautiful woman, I've seen it happening the whole time but never really noticed till now. After dinner I retire to my room, with the ideas still fresh in my head I think I'll just rub this one out and call it a night. As soon as I grab my lube in comes Courtney asking..."What are you doing?" You know what fuck it I think this is my chance, nervous as all hell I hand her the lube. She reluctantly asks "What's this for?" I peel back the covers to show her. She is a little shocked but I can tell...she knows what she's been doing. HOLY FUCK she agree's to give me a HANDJOB. Courtney applies the lube just the way I ask and begins to stroke my hard throbbing cock. I can't help but to think about what it would be like to actually fuck her. She keeps going on about how she thinks this isn't too bad and how she is "Just returning the favor." This had me going, I was getting close and could feel it about to happen...BOOM! Soon as I start to release it freaks Courtney out...I don't think she was expecting me to blow my load but she stops right when I start spewing cum. Courtney is completely disgusted...how am I going to fuck her now after that? Maybe I'll take her to the party this weekend...
