On the eve of my son Michael's nineteenth birthday we are laying on the living room couch kissing each other. Our family had been over at my parent's house earlier for dinner and my husband and daughter have just gone upstairs to bed.
I give my son another long tongue kiss then get up from the couch and ask him, "Michael, do you want to have a glass of sparkling wine with me?"
He replies, "Sure, then can I have the special birthday present you promised me?"
I tell him, "Maybe in a few minutes after I am sure your father and sister are sleeping and won't come downstairs and discover us."
After about an hour and a whole bottle of wine, my son suddenly pulls out his cock and pleads with me, "Please Mom, can I have my present now?"
I stand up in front of him, slowly unbutton my sexy little black dress then let it slide off my shoulders onto the soft living room carpet and say to him, "Well, what are you waiting for? Stand up and take your clothes off."
My son immediately jumps up from the couch and strips naked while I remove my bra and panties. I still wearing my black high heel shoes and when my son embraces me his big hard cock slides between my thighs. Oh my God, I have never thought about having sex with him while standing up! My high heels make me a little taller than him and his cock is now at the perfect height!
I reach down between my legs and guide his cock inside my pussy then he starts fucking me.
Oh my God, I feel this wonderfully erotic tingling sensation sweep through my entire body.
I am so wickedly naughty standing in the middle of the living room being fucked by my son while my husband and daughter are upstairs sleeping. This is a birthday of his that I will never forget!
After about four or five minutes my son says, "Mom, I'm going to cum at anytime! Can I do it inside you? Please mom, let me cum inside you! I don't want to cum in your mouth this time! I want to cum in your pussy! Please Mom!"
I reply to him, "Well, okay. After all, it is your birthday. Go ahead and cum inside me, but just this one time. Mothers should not let their sons ejaculate inside them because it is incest."
My son immediately grabs my naked ass cheeks with both of his hands and begins frantically fucking me!
My tits are flopping around wildly on my chest and he his thrusting his cock upwards inside me so hard that my feet are almost leaving the floor!
After a couple of minutes he suddenly stops and I can feel his cock jerking as it pumps warm sperm inside me. Oh my God, I get this incredible erotic sensation that sweeps through my entire body knowing that my son just fucked me standing up in the middle of the living room floor!
Michael waits a few moments then gives me a quick kiss and sits back down on the couch. I get a pack of cigarettes from my purse and light one up then walk around the middle of the living room while Michael intently stares at my naked body.
After a while I ask him, "Michael, do you really think I am just as pretty as the girls you meet at college?"
Michael replies, "You sure are and then some. You don't have an ounce of fat on you and your body is lean and toned from all the hours you spend swimming laps in our pool. Oh, and your tits are the best ones I have ever seen in my life. I really like their dark brown nipples that stand out about a half inch and are always hard. They look like a couple of large pencil erasers."
As Michael and I continue our conversation I notice his cock has become hard again and he is slowly masturbating.
I snuff out my second cigarette then step between his legs and turn around so my ass is almost in his face and say, "Michael, do you think my ass is too big?"
He stops playing with himself and begins squeezing my white ass cheeks. After a few moments he replies, "Hell no your ass is not too big. You look like a professional model when you are wearing your bikini."
Suddenly, Michael pushes my ass cheeks apart and begins licking my asshole!
Oh my God does that feel good!
After a few moments I stand up straight and take a few steps to the middle of the living room floor.
I turn around to face him then put my hands on my hips and say, "Michael, I gave you a very special birthday present earlier tonight and now you are going to give me one because all you got me for my last birthday was a card. I want to be fucked in the ass for the very first time and you are going to do it for me. Wait here while I run upstairs and get some body lotion."
Moments later I am on my hands and knees in the middle of the living room floor and Michael is behind me squirting a generous amount of lotion on his big hard cock. He guides his cock up against my asshole then grasps my hips and starts forcing himself inside me. The muscles in my ass try to keep out the intruder so I have to make a mental effort to convince them to let him inside.
After a few attempts Michael is slowly fucking my ass and I am in heaven!
Oh my God, anal sex is absolutely awesome! My son and I should have started doing this a long time ago!
After a while Michael starts speeding up and is really giving me the ass fucking of my life! My tits are flopping wildly around below me as I toss my long blond hair from side to side and quietly moan.
Suddenly, Michael stops and I can feel his cock jerking inside me. Oh my God, anal sex is awesome!
Michael waits a few moments then pulls his cock out of me and stands up. He helps me up to my feet then gives me a big hug and says, "Mom, I really liked fucking you in the ass. That was fun. Can we do it again sometime?"
I reply to him, "Well, let me think about it. It is getting late, now get upstairs young man and go to bed."
As Michael walks away he looks over his shoulder at me and says, "Mom, you are the best piece of ass that I have ever had in my life. I love you."
I reply to him, "I love you too honey."
