When Billy Screwed Mandy 2
Mandy begins to unbutton the shirt she’s wearing. She takes it off and tosses it on her bed to show she’s wearing a white lace bra underneath. Her body has matured a lot through the years. And while her breasts aren’t exactly the stuff of dreams, her firm, onion-shaped ass more than makes up for it. She stands up and begins to pull down her skirt, as Billy looks on, puzzled. “What are you doing, Mandy? Is it shower time?” Billy smells himself under his arms as Mandy steps out of her skirt, showing a black thong that she’s been wearing underneath. “No Billy, at least not yet. Now get up and come over here.” Billy complies with her request, picking himself up and walking over to her. Mandy stands up, meeting Billy eye-to-eye. “Drop your pants.” Billy becomes confused. “But Mandy, I don’t have my pajamas with me and…” Mandy’s eyes narrow as she looks at him. “Drop them!” “O-OK, Mandy.”
Billy unbuckles his belt & his pants and let’s them drop to the floor. Mandy examines what she has to work with, and her eyes widen a little. She looks to be in shock, but it can barely be seen. She sees the bulge in Billy’s boxers, revealing that Billy has been blessed with size down there. “Whoa, that’s bigger than anything I’ve ever seen…” She looks back up at Billy. “Do you realize what you got down here, Billy?” He looks a little embarrassed as he lowers his head & looks back at Mandy. “Yeah. Doctor says that most of my blood goes there instead of my brain.” “That explains So much.” Mandy reaches in his boxers and pulls out his massive manhood. She almost needs both hands to hold it. “OK, Billy. Time for your first lesson.”
Billy becomes inquisitive about what’s going on. “Is this gonna help me with not being from Virginia and make me a man?” “First of all Billy, you’re a Virgin. And yes, this will get rid of your problem.” Mandy licks her lips, and slowly moves her head towards his Cock. Billy has a confused look on his face. “What are you doing, Mandy? Are you gonna eat it?” “No, Billy. Just…” Billy’s eyes light up, as he thinks he knows what she’s gonna do. “OOH! I know! You’re gonna gimme a Wind-Job! Here, let me help!” “It’s called a Blowjob, Billy. And, wait…” Before she can react, Billy shoves his cock all the way into her mouth. He keeps pushing until it’s almost down her throat. Mandy starts to wave her arms wildly, as Billy grabs her head, thinking he’s doing it right. Finally, Mandy pushes Billy away from her and begins coughing and gasping for air. Billy smiles at her, thinking that he helped out. “Did I do it right, Mandy?” WHACK! Mandy smacks Billy’s jaw and almost knocks him down to the ground. She stares coldly at him. “Don’t…EVER…do that…Again!” Billy’s lower lip begins to quiver as his eyes well up. He realizes he’s made a big mistake. “Sorry, Mandy.” “Now come here!”
Billy approaches her again as she grips his Cock. “I shouldn’t do this after what you did, but I’m in a generous mood.” She opens her mouth and engulfs the head of his Cock. This time slowly, with her in control. She works her tongue around his head before moving further onto his shaft. Billy’s tongue is hanging out of his mouth as he is wearing a goofy grin on his face, even goofier than normal. “Oh, Mandy. This feels much better than what I did before.” She bobs her head back & forth off of his Dick, as she takes her and begins to caress his balls, her tongue going all over his Cock in a circular motion. Mandy gazes upward to see Billy looking down, staring at her breasts. He wants to touch them, but is nervous about what Mandy might do. Annoyed, she takes his Cock out of her mouth. “For the love of God, just Touch them already, Billy!”
He reaches down grabs onto both of her Funbags, rubbing on them and squeezing them together. He starts to laugh while he’s doing this. “They feel like pillows, Mandy!” Mandy rolls her eyes as she goes back to work on his Cock. “Gee, I wonder if it’s wise to introduce sex to someone like Billy.” Just then, Mandy notices that she’s getting into it herself…and getting wet. “What the hell? Just sucking off Billy does this to me? It has to be something else.” She ignores the feeling and continues to give him head. Billy starts to feel his knees weakening. He lets go of Mandy’s jugs and grabs her head, this time not as forcefully. “Uh…Mandy? Something’s happening. I feel strange.” Mandy doesn’t pay attention as she keeps up her pace on his Cock. “Really Mandy. It feels like something’s gonna…come out…” Billy lets off his load inside Mandy’s mouth. She stops her movement as semen erupts from his Cock. So much that it starts to dribble out of her mouth. Billy looks a little frightened, fearing Mandy might snap on him for doing that. “I’m sorry, Mandy. I tried to warn you.” Shockingly, Mandy takes his Cock out of her mouth and swallows his entire load. She then licks the remaining semen off of her lips. “It’s OK, Billy. I needed my protein for today. Now lie on the bed.”
Billy climbs back in her bed and lies on his back, as Mandy slowly takes off her thong, leaving on the high heels she’s wearing. Her legs are a little weak as she begins to climb into bed with Billy. “What the Fuck? I almost came just sucking off Billy. It…it must be stress or something. That’s all.” She climbs on top of Billy and straddles him, grabbing hold of his erect Cock. “What’re you gonna do now, Mandy?” “Nothing, if you don’t shut up.” She rises up and little and guides her way onto his Dick. “Now lie still. I’m in the driver’s seat.” Billy has a confused look on his face again. “But we’re not in a car, Mandy.” She sighs, reminded once again of his stupidity. She lowers herself onto Billy, and is immediately overcome with pleasure. An amount that she isn’t use to feeling. “Damn…his Cock is filling me up. Come on, Mandy. Keep control.” She works her hips a little, up & down to get the friction going. Billy’s eyes almost roll back into his head, as he grips the sheets of her bed. Mandy sees this and knows she’s doing a good job. “So how does it feel, Billy?” Billy grinds his teeth a little, but not necessarily in pain. “It…feels tight…and warm…” “It’s supposed to.” She leans in a little closer, and picks up her pace as she bounces up & down on his Cock. Billy looks up and sees Mandy’s tits just mere inches away from his face. Instinctively, he shoots up and begins to lick & suck on them. “OOOOOHHHHHH!!!!” Mandy lets out a loud moan, followed by a look of complete shock filling her face. “What the hell? Did I just moan?”
She begins to feel a little weak, as if her body is succumbing to Billy’s actions. She shakes the feeling off and a look of somewhat rage forms on her face. “I don’t know what’s going on, but I won’t let this defeat me.” She begins to bounce even faster, wanting to end this romp with Billy before something else happens. Billy switches focus from her breasts and gets a tight grip of her ass. Mandy begins to sweat, but keeps her composure so far. “Billy should be ready to blow any moment now. And I can finally…” Without warning, Mandy feels herself flipped onto her back, with Billy on top of her.
“Billy, what the hell?” “It’s my turn for the Driver’s seat.” He giggles & laughs as he begins to pound Mandy’s wet pussy. He lifts her leg up onto his shoulder and goes deep inside her with each stroke. Mandy bites her lip as he feels herself losing control. “Dammit, the one thing he’s good at and it had to be sex. I can’t let this happen. I have to get control!” Just as she’s thinking that, Billy grabs her other leg and lifts it just slightly. He begins to drill her pussy Balls Deep. The entire bed is shaking & squeaking to the point you’d think it would fall apart. Mandy bites her index finger, as her breast bounce wildly around. Her hair is a complete mess and she’s pouring sweat from he body. “Oh God! It’s so good…he feels so good…” Billy is also sweaty, and looks like he’s trying to hold on to make it last as long as he can…but it’s a losing battle. “Mandy, I’m…I’m getting that feeling again!” Once again, Mandy doesn’t listen. She rubs her nipples & her breasts, then closes her eyes, as she feels her body finally giving in. “Dammit! I think…I think I’m gonna…”
Billy lets go, and cums hard inside of Mandy. It sprays out like a fire hose from his Cock. Mandy does nothing to stop it, as she lies there sweaty and breathing hard. Billy falls to the bed, just as sweaty, landing right beside her. After a couple of minutes, Mandy rolls over and sits up on the edge of the bed. She stands up and grabs a robe that’s hanging on the wall and puts it on, before heading to the bathroom. Billy looks over to see her out of the Bed. “Where ya going, Mandy?” She stops in mid-walk, and waits a moment before she answers. “To the bathroom, Billy…to do some thinking. You just get some rest.” Billy does so as he falls asleep on her bed, as Mandy continues to the bathroom.
An Hour Later…
Billy opens his eyes to see Mandy standing by the window. She’s just finished getting dressed back in her Business suit. She looks over and notices that Billy’s awake. “Good, you’re up. Room service will be here shortly with some food.” She finishes buttoning her sleeve as she walks towards the door. Billy wonders what’s going on. “Where ya going now, Mandy?” She stops and looks over at him. “To the Abortion Clinic. I left some Video Games for you to play with by the TV. By the way, you’re no longer enrolled Indiana University. I took the liberty of enrolling you at Dictator School. You’ll be taking the Evil Lackey Course.” There’s a long silence as Billy takes in everything that Mandy just said to him. “OK!” He hops out of bed and sits down in front of Mandy’s Plasma TV and begins to play the games she’s gotten for him. Mandy opens the door and is about to walk out when she looks back at Billy. Shockingly, a grin comes to her face, without the world exploding or reality changing as we know it. Not even an Earthquake or Natural Disaster. She walks out and shuts the door behind her, leaving Billy with the games.
A Few Days Later…
Grim is walking with Mandy through the streets of Endsville once again. “So, let me get this straight. You take Billy out of his party school, and enroll him in your school, to take the Evil Lackey Course.” Mandy nods her head yes. “The way I figure it, he’d just be exploited in the NFL, if he makes it there.” There’s a smug grin across Grim’s face. “Mm-Hmm. And this isn’t about you and Billy getting together to do the Horizontal Polka.” Mandy shoots a cold look at Grim, which makes him think about what he said. “Nevermind.” “Look, Billy out in the world alone doesn’t stand a chance of surviving. At least if he’s with me, he’ll be safe. Plus, I gain a Henchman that I can train.” Grim nods his head in agreement, then gains back his smug grin. “So you do care about Billy.” Mandy narrows her eyes as she looks back at Grim. “If you tell anyone this, I’ll stick that Scythe where the sun doesn’t shine. Understood?” Grim looks away from Mandy, as they continue on their walk. But he still holds the grin on his face. “Understood.”
