Doggie Style

"Well..." you think. "there are some things that most girls don't like that the really wild ones seem to enjoy..."

Smiling wryly, Velma moves her right hand from your hip to your crotch, giving your manhood a firm squeeze. "No reason to beat around the bush, so the speak... I've already deduced what your most likely request would be.

Taking a step back, grabs the bottom of her sweater and starts to pull up. Immediately you see that her hips do curve into a pleasantly slimmer waist, previously hidden by the bulky sweater.

You hastily unbuckle your belt and drop your pants in anticipation of this toon has in store for your cock.

Higher the sweater goes, revealing a pair of unfettered D-cup breasts swaying freely as the fall out of the grip of the garment. Carefully lifting the sweater over her head and glasses, she removes it and lets it fall to the floor. Reaching up under her short skirt, she quickly yanks down her panties and steps out of them. Looking up, she takes notice of your hardening prick.

"Excellent specimen you have there!" she exclaims. She takes your cock in both hands and begins to rub it gently, feeling the length and girth of your member. Dropping to her knees, she begins to trace her tongue up and down you shaft and around the tip, her warm saliva sending tingles of pleasure through your body. After a few moments to ensure your prick is sufficiently lubed up, she moves to your desk. Leaning over the surface of your desk and resting on her elbows, she wiggles her ass invitingly towards you as she looks back at you over her shoulder.

Smiling you walk up behind her, admiring her full round ass. You caress her bottom with your hand for a moment, feeling her creamy smooth skin. You lean forward, resting your cock between her ass cheeks as you reach around and grope her heavy tits. She moans slightly as you tweak her nipples with your fingers. Standing back up, you pull away slightly before slapping her ass hard with your hand.

"Ooooh." Velma moans. You smack her ass again, a little harder, leaving an angry red imprint of your hand on her backside. "Ooooooh."

Grabbing your cock, you gently press it between her legs and rub it up and down the length of her sopping wet cunt, spreading her juices all over your member to provide extra lubrication. Velma begins to squirm as you relentlessly tease the clue finder with your thick pole. Finally able to take no more, Velma re-positions her hips slightly and slams back against you, pulling your cock deep into her slippery hot cunt. "Aaaaaaaaaah!" She cries out as you spear her with your tool. As she prepares to slam back into you again, you grab her hips and pull out.

"Tsk, tsk, tsk... you failed to properly follow the clues to their logical conclusion, Velma. The experiment is to determine how wild nerd girls are... there is nothing wild about fucking a woman's pussy." Moving your dick up slightly, you rest the tip of your cock at the entrance of her tight little asshole. "Your ass, however, would be a suitable test environment."

Looking back at you with her eyes wide, she gasps slightly in anticipation of your next move. "Fuck my cunt, fuck my mouth, fuck my ass... I don't care, JUST FUCK ME!" she begs.

You slowly push the head of your cock into her ass. The combination of her saliva and pussy juices allowing you to ease your dick in despite the extremely tight fit. The hot walls of her ass gripped your prick like a vice. You are about halfway in when Velma takes matters into her own hands and slams her body back against yours once again, driving your shaft into her to the hilt. "Uuuuuuunnnnnggggg!" she cries.

You slowly start to thrust in and out of her ass, caressing you voluptuous curves of her hips with your hands. The cheap desk creaks with each thrust, Velma's brown bobbed hair swaying back and forth. She arches her back and stands up slightly, increasing the tightness of her ass and brushing her soft hair against your chest. You respond by reaching around and fondling her huge swaying breasts, kneading them in your hands as you continue to pump her from behind.

Grabbing her waist, you begin to increase you pace, forcing her to lean back over the desk once again. Now the cheap student desk was slamming against the wall with each thrust, some pens and computer discs falling to the floor as you pummel Velma's ass from behind. Grabbing hold of her skirt, you push her forward against the desk with a thrust of your cock, lean back and then pull her body towards you by the skirt, slamming her ass back on to your dick.

"FUCK MEEEEEEEEE!" she cries out as your pounding reaches a frantic pace. "FUUUUUUUCK MEEEEEEEEE"

You feel yourself ready to cum. Sensing your impending release, Velma cries out. "Wait!" Pulling your cock out of her ass, Velma spins around and drops to her knees in front of you. Before you can realize what she has in mind, she grabs your throbbing prick and devours it with her mouth, sucking and licking hungrily despite the fact that it just came from her ass.

The sight of the mystery solver going ass-to-mouth combined with her tongue flicking about your head pushes you over the edge as you send wave after wave of cum down her throat, which she dutifully swallows. As you finish, you slowly pull your softening member out of her mouth as she begins to stand up.

"Test complete, analysis?" she asks.

"Definitely the best head I've ever had... no question there. I've never had a girl go ass to mouth..." you respond.

"Good." She says as she stands up. "Hypothesis confirmed." Velma begins to go about getting dressed as if nothing had happened, like it was the conclusion of any other experiment. You slowly get dressed yourself as you watch her get ready to depart.

"Well, thanks for the fun." She smiles. "It was a nice break from watching Daphne getting all the cock all the time. If you can think of any more 'experiments' you need my assistance with, you know where to find me." With that, she jumped back into the poster, her body resuming the cartoonish appearance as she transferred from your world back into hers. Once again, she was in the poster picture, but this time, she had a devilish grin on her face.

Spent, you toss yourself onto your bed and drift off to sleep, replaying your encounter with the mystery solver in your head, thinking of what your next "hypothesis" would be.
