In The Chair

"I've got just the thing to clinch this investigation..." You grin. You turn your desk chair around to face her and take a seat. You beckon her to you with your finger. "Come here."

Coming to you as directed, Velma kneels down between your legs and takes your cock in both hands, licking and coating your cock with her saliva. After a few moments to ensure your prick is sufficiently lubed up, she stands up and turns her back to you, slowly lowering her ass towards your hungry prick.

Smiling you admire her full round ass. You caress her bottom with your hand for a moment, feeling her creamy smooth skin. You start to gently knead the flesh of her cheeks, feeling the heat building between her legs with your fingers.

You pause a moment to slap her ass hard with your hand.

"Aaaaah." Velma cries out in surprise. You smack her ass again, a little harder, leaving an angry red imprint of your hand on her backside. "AAAAAAAHHHH!"

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.

"Please...." she begs. "please fuck me. I can't stand it, I need to feel you in me."

You continue to tease her, grinding your cock against her clit from behind without actually placing your dick in her hungry cunt.

"Aaaaaaaaaah!" She cries out in frustration. "FUCK ME!"

Moving your dick up slightly, you rest the tip of your cock at the entrance of her tight little asshole. Looking back at you with her eyes wide, she gasps slightly in anticipation of your next move. "Wait, I've never..." she begs. She starts to stand up and pull away, but you tighten your grip on her hips and pull her back down to you. 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.

"NOOOOOOO!" she cries out. The hot walls of her ass gripped your prick like a vice. "Aaaaaaaggggh!"

You continue to pull her down and push in to Velma's tight little ass, pausing to slowly fuck her for a few moments after every inch you fit in. Soon, Velma's cries of pain and horror turn into low growls and moans of lust.

"OOOOOOOOOOOOHHHHH". She moans.

You are about halfway in when Velma takes matters into her own hands and pushes her body back against yours once again, driving your shaft into her to the hilt. "Uuuuuuunnnnnggggg!" she cries.

She slowly start to move up and down, moving your cock in and out of her ass while you caress the voluptuous curves of her hips with your hands. The cheap chair creaks with each thrust, Velma's brown bobbed hair swaying back and forth. She arches her back and sits 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 she continues to ride your dick.

Leaning forward, she begins to increase her pace, bouncing up and down on your member with wild abandon. Grabbing hold of her skirt, you pull her down forcefully to meet each thrust of your cock.

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

You feel yourself ready to cum. To Velma's surprise, you pull out. Grabbing her by the shoulder, you spin her about and quickly push her down to her knees before you. Grabbing her head with both hands, you point your throbbing prick towards her mouth as her eyes go wide.

"Open your mouth!" You demand.

Hesitating for a moment, a single tear rolls down Velma's check. Regardless, she complies and devours your cock 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 as she grimaces from the taste in her mouth.

"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. You slowly get dressed yourself as you watch her get ready to depart.

"Well, thanks for the change in pace." She offers. "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 small spot of cum on her chin.

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.
