I had a former girlfriend in my early days while I was living with my parents, but there came a time that my GF's older and married sister was away on vacation and my GF was given the house key to take care of the plants and check up on things!
I drove her over there a few times and after that it got to be a great place to have a make out session, but nothing way over the limit.
Then this last time we were there, my GF went into the bedroom while I was watching TV and she called for me.
When I got to look inside the bedroom, I could see her laying NUDE on the bed and asking me if I wanted to go a little further for play?
I said sure, then I stripped down and got to check out all of her private features by hand and mouth. It wasn't long before she started doing the same to me.
Before long I was on top on her and she took my hard cock and put it inside her pussy after a few misses!
I believe both of Us were having that magical moment and it was our first time at going this far because of having a place to finally do it!
Then after plenty of pounding and I was thinking that I was going to CUM soon, we had a strange moment and heard a Voice.
It was my GF's married sister standing in the doorway with the ability to view everything from our NUDE bottom's.
Not sure if she could see my cock inside her sisters pussy, but I'm sure she seen my Balls bouncing around and my Ass in sight too!
But the one thing that I can remember her saying to her hubby was as she walked out towards him was, My sister is getting Fucked in our bed!!
By then the hubby rushed in the bedroom and seen both of Us NUDE and trying to cover up and put our clothing back on.
I got to leave a short time after, but my GF had to stay and have a conversation with her older sister.
They didn't report Us to her parents, but I had a conversation some time after with the married sisters hubby about the great body that his SIL has and he wondered if I had any pics of her to show him in exchange for pics of the older sister? I told him that I didn't have any or a camera to take them with, but he was willing to let me use his camera and still showed me pics of his wife - the older sister Nude!
It ended up one of those moments that sticks in your mind and has you wondering what If ??
