I woke up this morning with the memory of what happened last night very much fresh in my mind, and my friend sharing my bed. My step dad Frank isn't your typical step dad, he's got a very young outlook on life and if I'm honest I'm surprised he's with my mom, who certainly hasn't, but hey she's still my mom. Kerry my friend is a real stunner (not that I'm not good looking :)...) and I knew she was attracted to my step dad, but not in a million years did I think I would see what I did last night. My mom was at work and wasn't due back in until after midnight, it had gotten to eleven pm and I was tired. Leaving Kerry and Frank chatting I went up to bed and was awoken by what I thought was loud moaning. Putting my robe on I walked downstairs to witness something which I still can't get my head around.
Lay naked on his back on the lounge rug was Frank, sat on his cock facing away from Frank was Kerry, happily bouncing on his dick, but the most surprising part was seeing my moms bare ass sticking up as she knelt down and she was licking Franks cock and Kerry pussy alternately. I watched stunned for about five minutes, before I thought they saw me. Back in bed I listened intently to them having sex and must have drifted back off to sleep, because the next thing I knew Kelly was getting in beside me with her night clothes on. I petended to be asleep and eventually I did sleep waking up with Kerry's arms around me. She left two hours ago after kissing me a little more seductively than normal and also saying "I'll text you later so we can arrange about me staying next week". My parents are away next weekend and now I'm thinking Kerry wants sex with me too. Sorry for all the swearing but everything just seems so fucked up at the moment, I can't think straight about what I should do or say to my mom and step dad, let alone Kerry. What the hell should I do ??
