Get Biff off yourself
From Create Your Own Story
You aren't sure if you could get your mom to go out to the lake with you unless you promise her a jug of wine. Besides, you don't like the idea of Biff perving on her while you're there. You decide to make a much more direct approach.
You reach over to Biff's side of the car and cup his growing crotch with your hand. He looks at you with wide eyes and is about to yell when you give his hard cock a little squeeze. You see his face freeze and feel his cock get even harder at your touch. "I don't think we need to wait till this weekend to get you taken care of." you say as you start to stroke his cock up and down through his pants. He closes his eyes and leans his head back, clearly surrendering and letting you get him off. You fiddle with with his belt buckle and his undo his zipper. Biff's cock is about 7 inches long and thick as a coke can. You marvel at before you lean down and suck the head into your mouth. Biff begins to moan in pleasure, not taking any precaution at being quite. You think might even want your family to hear this.
You take Biff's cock deeper and deeper into your throat which makes the man groan more and more. Biff's groans were turning you own so much, you felt very hot. Even with his cock in your mouth you feel a aching in your ass tell you that you needed to bury that cock inside you. You begin to undo your own pants while keeping that rod in your mouth. Eventually you slip them off along with your shoes and are now naked from the waist down. You reach over to the side of the driver's seat, find the lever that adjusts the seat's position and pull it. Biff slides backward, alarmed for a second. He still looks confused when awkwardly move over to the driver's seat to straddle him. Only when you are holding his cock with one hand and lowering yourself onto him does he comprehend.
"Goddamn," he says, "McFly finally did something right when he made a cockslut." He laughs and grabs your hips, holding you in place as you take him into you. He doesn't seem like he likes to be gentle though and no sooner had you taken his cock in your ass then he began lifting you by the hips, just to slam you back down on to his thick dick.
It stings at first but you try to hide it. You try to morph your cries of pain to sound like moans of pleasure which just make Biff go harder and harder. Eventually you find a position which makes Biff's thrusting cock hit your good spot every time. That's when you really let your moans run wild. You no doubt sound like to cats rutting in an alley but you don't care who sees or hears. "You know when I was younger," Biff continued, "My gang would grab a weak little homo or two and fuck them in the allies. We knew they wanted it but they would waste so much time bitching and crying. But we would have done anything for a willing slut like you." At the word "slut" Biff your ass a hard smack which made you moan.
As you and Biff continue to rut your eyes meet for a second and you can't seem to break his gaze. You look into his eyes and see that slimy grin he usually only gave when he saw your mom but this time his face was flushed and bit sweaty from your efforts. You feel the sudden urge to leaned down next to him and kiss him. At first you feel him jerk his head back but then he kisses you back. Not in a sweet, tender way. It is clear his enjoyment from kissing you is perverse. His tongue darts inside your mouth, swirling around your own tongue and probing the rest of your mouth. The taste of beer is so strong in his mouth you might get second hand drunk. He slaps you ass a couple of times and thrusts up into you. He breaks the kiss to say that you are a "Hot piece of ass" and that you, "Are way tighter than he though your mom ever could be."
At this second comment you feel his cock twitch and you know he is about to cum. He pulls you back into a greedy, degrading kiss as he grabs each of your cheeks roughly and brings you down, hard onto his cock. His cock erupts in inside you and you feel his sticky cum flood your ass. He gives your ass one hard slap before he says, "I am gonna ride that cunt every chance I get."
You are very sore and it hurts to extract yourself from Biff. You grab your stuff from the passenger side, open the door on the drives side and get off of Biff and step out onto the street, still nude below the waist you try to hurriedly pull your pants on, you leave your underwear, socks and shoes off and just hold them your hands. The second your pants are on, Biff grabs you by the shirt, pulls your head back into his lap, forces his softening cock back into your mouth. "I want you to get every... last... drop..." he says as he humps your face. You take this abuse while secretly enjoying the pungent taste of his cum in your mouth. Finally satisfied he lets go of you and gives you a perverted leer. "With your daddy's car totaled, just know that you can always call me for a ride. We don't even have to drive anywhere." Biff laughed at his own obvious pun as he pulled out of the drive way, knocking over the neighbor's garbage can as he did so.
You walk to your house for dinner. If anyone in your family notices that your wreak of beer, cum, and sweat or that your underwear, shoes, and socks are in your hands, they don't mention it.
