On Christmas Eve my mom and step dad Ian held a party. Our whole family was there as were lots of our friends. As usual people commented on how much my mom and me looked alike, only she might be my older sister.
Late on I decided with my boyfriend wasted lay out on the kitchen floor, I was going to bed. As my mom was asleep on the couch and my cousin had taken my bed, I decided that I'd sleep in my mom and Ians room. Thinking Ian would crash out with my mom.
At first I didn't quite understand what was going on as I'd a few drinks, then I realised I was being tongued from behind. My pussy and asshole were taking a very good licking and it felt awsome. Usually I have to beg my boyfriend to tongue my ass, as I love having it done, but it seemed he didn't need asking. I orgasmed lay on my left hand side without turning over once, the cunnilingus was that good.
Only when I felt him rise up my body and I could feel a hairy chest on my back, did I know it wasn't my boyfriend, as his chest is smooth. I froze, I know I should have said something but I just froze, so when I felt the mans cock nudge up against my pussy I just let him enter me.
I genuinely was about to tell whoever it was to stop, but his long thick cock felt so good inside my pussy, I let out a moan of pleasure rather than a cry of refusal.
Over the next five to ten minutes I was fucked from behind. Not made love to, but fucked and fucked so good I came again. I even heard myself ask him not to stop. His arm reached under me and took hold of my left breast as his right hand snaked down to my clit. He continued to fuck me and I continued to cum again and again. I'd never had that many orgasms in one go before, and just before he pulled out to ejaculate all over my lower back and asshole, I was willing him to cum inside me.
Not moving, I let him hold me tight. Then I heard him say "Penny, don't tell your mom, she wouldn't understand".
So it wasn't a mistaken identity from Ian. He knew exactly who he was fucking and as far as I was concerned at that precise moment, I couldn't have cared less.
Ian got out of the bed and covered me up, then walked out of the room naked. I slept like a baby and woke up to the sounds and smells of cooking coming from the kitchen. My boyfriend was outside smoking when I went downstairs, and my mom was doing the cooking. Ian said hello in a very calm and knowing way as I sat oposite him at the table. When my mom went out to get my boyfriend for breakfast, I told Ian it wasn't going to be a one off. His smile and his foot reaching under my short bathrobe, touching my naked pussy, told me it definitely wasn't going to be a one time fuck either.
New Year now, so we'll see if I get to have Ian all to myself when my mom goes back to work.
