Visiting my mom and dads home recently with my new boyfreind Jack, I had to let us in with my spare key as my mother text me to say they were out shopping, adding they'd be home in about an hour. Feeling very horny I slid Jack looose fitting trousers and boxers down and took his large cock into my mouth. He became erect very quickly and after nly a few minutes he asked if he could fuck me. I don't use pills as birth control and we didn't have any condoms with us, so I told Jack to fuck me in the ass.

Jack had not long begun to thrust real hard up my rear, making me moan loudly with pleasure he was giving me, when my mom and dad walked in. There I was my skirt up around my waist, my panties on the floor near to where they stood, and I had Jacks cock pounding away at my asshole. My dad looked furious, but my mom looked kinda envious. Sh even smiled and walked away. My dad screamed at us to stop, but unfortunately Jack was too close to cumming and shot is load deep inside my asshole. Only when he'd filled my rear fuck tube did Jack pull to reveal his rock hard boner.

Mom came back in, gave a tissue and laughed at my dads face, telling him I was old enough to have sex. All the same I went bright red and hurridly got dressed, making Jack hurry too. We made our excuses and apologised then left, but not before I heard my mom say to my dad "Hey Bill, maybe you could do me like that later".

I don't know what was more embarrassing, us getting caught, or hearing my mom ask my dad to fuck her in the ass??
