"I heard it was your birthday, and I wanted to do something special for your birthday this year!" my step-mom, Melanie, says to me, as she walks in to my bedroom. She is wearing a bath robe, but she quickly unties it and she reveals her naked body in front of me. She walks closer to me and then she hops on to my bed and she pulls my cock out from under my shorts! "What are you doing?!" I ask her. "It's your birthday! You deserve this!" she responds. She wraps her lips around my cock and she starts to give me a blowjob. After she sucks my cock for a few minutes, she tells me she is going to give me her ass too! I can't believe what I am hearing! She lies down on the bed in the missionary position and I shove my cock in her pussy first. After a few minutes, I ask her if she's sure that she wants to have anal sex with me. "Yes, I want to try it!" she exclaims. While she is still lying on her back, I shove my cock in her ass. "How is that?" I ask her, as I slide my cock in and out of her ass hole. "It feels so good!" she tells me. After a few minutes, I ask her to flip over in to the doggy style position so I can fuck her ass from behind. "Are you going to cum for your step-mom?" she asks me. I keep fucking her ass until I cum inside of her ass! "At least I can't get pregnant that way!" she tells me.
