As Nat pushes you onto the bed she turns and locks the door so no one disturbs you as she slowly and seductively moves up your body towards your face inches away from each other she begins unbuckling you belt and moving you pants off of you and she moves down (your shirt was taken off on entry to the room) she kisses down your chest and along each ab and then her face meets you boxers she pulls them down to reveal you erect cock grabbing it with her hand making you shiver as her hands are cold she sees it in you eyes as she's pumping you up and down she smugly says "oh is that cold here let me warm it up for you" wrapping her mouth around you tip taking a few inches then a few more and then a few more until she has your entire shaft in her mouth bobbing up and down fervently this goes on for a few minutes until you feel the pressure building up you warn Nat but she just moves faster and faster playing with your balls in her hand you release in her mouth and she gulps down every last drop moving back up face to face she smiles "delicious" she says you flip each both of you around so now you're on top and you now realise Nat is naked taking this opportunity you attack her breasts sucking on one whilst groping the other this causes Nat to moan a lot underneath you then you take your free hand and slide two fingers inside he soaking pussy fingering her at top speed this throws Nat into a moaning mess thank god these walls are soundproof you stop and Nat stares and you as you slide down with your head near her wet folds patching your mouth onto her clit making Nat let out another ton of moans she grabs your head pushing it into her "oh yea that feels sooo fu..fucking good" you were flicking your tongue in all directions and you notice Nat squirming more and more so move faster as her juices coat your face and you lick them all up you move over her your tip touching her clit and you stare at each other for a second and Nat gives you the nod as you push into her then pushing your lips together in a heated make out muffling her moans and you are pushing in and out of her with power and speed you are grunting and Nat is moaning you were both in pure ecstasy enjoying every moment then Nat flips you over into cowgirl position and she begins grinding her hips back and forth up and down getting into a rhythm you notice this rhythm and grab her hips and begin to piston upwards into her you both moan strongly and you shoot your load inside of Nat and she cums all over your cock you both breathing heavily and Nat climbs off and lays next to you then you realise you weren't wearing protection "OMG Nat *pant* we weren't wearing a *pant* condom" you stress she stays calm and says "don't worry I can't physically get pregnant because of what they did to me when I was younger" you sigh in relief but also a little sadness as you now can't have a child with her Nat lays her head on your chest and you pull a blanket over the both of you and you both begin to sleep
