I (22m) visit my friend (23m) quite often as we have been friends since school. He still lives with his parents and sister (19f). One day, I went over for some games and it was just him and her in the house. I could tell she was into me for a while but this time she was wearing I slutty outfit and would always stand in the doorway where I could see her but her brother could not and pull her hand across herself in a tempting way.

This got me excited as she obviously had planned so when the opportunity arose I followed her upstairs under the guise of popping to the loo, leaving my friend downstairs. She was waiting for me and got straight on her knees in her bedroom and sucked me like a pro - apparently her ‘first time’ but I don’t really believe it from the blowjob.

More believable though when she pushed me back on the bed and straddled me and I felt how tight her pussy was. We’ve fucked since and the fact that it’s my friends sister and it’s secret while he’s downstairs makes it sooo hot.

That first time I finished in her then rushed downstairs as I know I had been a while. I was so sweaty and hope my friend didn’t notice how out of breath I was and how messy his sisters hair was when she came downstairs next with my load leaking from her pussy
