I wake up late in the morning and find you sitting on the couch watching tv. "Good morning and happy birthday!" I rub my eyes and try to wake up. "Thanks, Good morning." You smile "I got a present for you. Go put on your girlie things so I can fuck the birthday girl!" "Hell Yeah!" I turn and walk back. You look over your shoulder "And meet me in the bedroom when you're done." As you lay naked on the bed, I walk in. I've got long auburn hair and I'm wearing a baggy tank top and a pair of shorts cut away to look like a thong. "Ho Lee Shit!" you give a small whistle. "That's awesome! Show me your tits!" I smile, pull my top aside and show you my big milky white tits with big brown nipples in a see through white bra. "Come over here and let me feel them." While you're still laying in bed, I move close and bend over so you can reach them. As you begin to play with my exposed tits, you smell my perfume. "Them are some REAL nice tits and you smell great too. Turn around so I can play with your ass." I giggle and turn. You stroke my ass cheek and admire my long smooth legs and shapely ass. You continue to stoke my thighs and ass. "Those shorts make Daisy Duke look like a girl scout." Only the pockets and center seam remain. I smile, bend forward and feel the seam pull tight into my ass crack. As I do this, I look over and see your cock getting hard fast. "God that's hot! I'm ready for the birthday girl to get up here and ride my cock!" I quickly shed my top and pull down my shorts and panties. As I do this my hard cock springs out. "Wow, you are definitely ready to be a birthday slut! Aren't you?" "I sure am! Just slap my ass and call me Susan. I am definitely your slut for the day!" I say as I climb on top of you and straddle your throbbing cock. I position your cock at the opening to my tight puckered hole. As the head pops in you can feel that my ass is already lubed and ready to go. I push back and moan as your cock slides balls deep into me. You feel your cock surrounded and enveloped in my tight wet hole. I squeeze my ass tight around your shaft and begin to move my hips slowly up and down. When I move up again you grab my thighs and start pounding your cock into me with a fury of lust. You start to moan and make faces as you thrust into me. When you start to make declarations of what a hot juicy piece of ass I am. I smile and sit back down "I'm gonna ride your cock long and slow Bob. Get ready for a marathon fuck." Your eyes fly open, you roll me on my back and pin me down. "Oh no you don't! Susan! You said you were going to be my slut! You look smell and feel like a whore and I'm gonna fuck you like one! So shut up and take it!" I smile and spread my legs as you slide your cock back into me. "Do me Bob!" You lay on top of me, bury your face in my shoulder and start fucking me hard. Your cock slams deep into me over and over. I can hear you grunting as your cock slams home. You pound into my tight juicy ass while I squirm like a bug on a pin. It feels so good while you plunder my booty that I respond with "Oh God That feels good." and "Ah Ah Ah!" noises. I begin to squeal and thrust my hips to meet yours in a rhythmic motion. Your cock is pistoning into me like a jack hammer. You pull back till just the head remains inside me then slam it balls deep into me. You ride me like a well worn slut. Fucking me like the whore I want to be. You fuck me for what seems like forever and it's more than I can take. I wrap my legs around your waist and begin to squeal and buck my hips. I let out a loud "AHHHHH AH AH AH!" and cum shoots out of my cock making a wet spot between our bellies. As I scream my approval you feel my asshole convulsing around the shaft of your cock. You keep fucking me but it is now more than you can handle. You groan and drive deep into me. I can feel your cock throbbing inside me as my fuck hole is flooded with cum. When you finish filling me with sperm. We both lay panting and trying to catch our breath. Sweat covers your face as you look at me with a smile. "Fuck that was awesome!" you say as you continue to slide your cock in and out of my cum soaked hole. "Susan, If I had known you were that good a piece of ass, I woulda started fucking you years ago!" I smile pleasantly "If I had known you would fuck me like that, I woulda been begging you to fuck me!" The whole time we talk you keep sliding your cock in and out. "Well Susan, get ready, here it cums again!" Soon you begin to pick up speed and drive into me with force. Within seconds we're back in the rhythm. Your cock is pounding into me. I'm squealing with delight. Cum is splashing everywhere! And you're hard at it! When you cum the second time, you roll off me and lay there. "Did you like your birthday present as much as I liked giving it to you?" "I sure did! It was prob'ly the best birthday present I ever got!" "Cool, cus you're gonna get it a few more times before the day is done."
