His Sister Caught Me Smacking It To Their Mom

My buddy's mom was super hot when we were around 15 years old. They had a pool and during the summer she would walk around in a thong just doing regular yard work thing, swimming and dinner. She would purposely bend over in front of the boys when we were over and we all used to jerk off thing and picturing her. The one day swimming we were diving under the water to pick up sinker toys when she was in the pool and while down I glanced over to try Nd see her ass or camel toe and her bikini was moved to the side and i got an eye full of pussy. Obviously she was doing it on purpose but damn was it fucking hot. Not long after that I went to the garage that had a window to the pool where I could still see her and like the horney kid I was started smacking one off in front of the window linda hopping it would grab her attention. I'm rock hard in front of this window with a hand full of dick I'm about to burst right when his sister charges threw the door and sees what I'm doing. OH MY GOD she said loudly...ssshhhhhhhh I said I'm sorry please dont tell anyone. Your jerking off to my mom you fuck! I know I know please don't say anything . As im about to leave super embarrassed she tells me to stop! In my head I'm like oh God what what now. The horney little sister tells me she won't say anything if I finish myself off in front of her saying, ive never watched a guy jerk off in person. I'm like wtf Jessica!!?? Do it or ill tell everyone. Fuck me this is bad but I did it. She stood there and watched with my swim suit at my ankles jerkoff until I shot several large loads on the garage floor by her feet. She approached me and said that was hot. Ill let you know when I want more and she did a few times a month. They ended up moving away which I was pretty happy about
