Grunkle Stan sat alone in the kitchen of the Mystery Shack, his laptop on the table in front of him. He opened up internet explorer and typed in: hot red head gets pleasured before slipping his hand into a slot in the skirting board and pulling out a bottle of lube. He pulled his pants out just enough to expose his erect eight inch member and applied a generous amount of lube, sat back in the kitchen chair and clicked on a browser link. As he watched the sexy redhead dance round on the computer screen, he began to move his hand slowly up and down his dick. Then faster... and faster... he was almost at climax when he stopped. He was better than this... wasn't he? He looked back at the computer screen where the woman was still dancing sexily. It reminded him of someone, but who? That's when it hit him, WENDY! He stumbled round the mystery shack in the dark, his penis still hanging out and trying his best not to wake Dipper and Mable who were sleeping peacefully in their attic bedroom. When he found his way to the phone he dialled Wendy's number. It rang for a while before a sleepy voice answered the phone. "Hey Stan, its like two in the morning, what's up?" said Wendy in a drowsy tone "Wendy there's some erm... late night tourists come over and I need you come and, erm... do that... thing you to... at work... and... stuff." Wendy was sceptical, but said she would be over in about fifteen minutes. When she arrived she was about to knock the door when Stan stopped her. "Wendy," he whispered, "come with me." He tugged Wendy back down the porch steps, towards the shed at the back of the shack and pushed her inside, before she could resist he too stepped inside and locked the door behind him. He turned on the flickering light that hung above them and began to undress, Wendy was shocked beyond belief! So shocked in fact, that she fainted! This was just more convenient for Stan of course, it just meant he didn't have to deal with Wendy struggling. His cock was still erect but now seeing Wendy, it was throbbing. He stripped Wendy down exposing her young tits and unshaved vagina. Stan was practically drooling at the sight. He had forgot his lube in the shack in his rush to get out and away from where Mabel and Dipper were sleeping, so his spit would have to do. He lathered his member with his saliva and angled it to Wendy's tight, unpenetrated vagina as he had lay her across an old cabinet which he had stored in the shed. He didn't go straight into Wendy, instead he prodded her, poking her, stimulating her clit with the head of his dick. His pre-cum was already flowing. That was it, he couldn't hold it anymore! He shoved his cock forcefully into Wendy's virginal pussy, making him grunt with pleasure, it had been too long since he had last felt the inside of a woman, and the fact that it was a teenaged woman made it feel even better. He began to thrust in and out of her, slowly to make sure she didn't bleed, he needed to... stretch her out... he looked down at her unconscious face and didn't feel the tiniest amount of guilt. Thrusting in and out of Wendy he grunted, louder and louder with every push and his balls slapping against her round, smooth ass. He took his cock out of her, it was dripping with Wendy's vaginal juice which aroused Stan even more. He then inserted it into her asshole which was even tighter than her pussy but a lot dryer which Stan didn't like so once again he took out his dripping member and inserted it into her mouth. He thrusted in and out, pulling her head towards him at the same time and massaging his dick. This was where he belonged. With one final thrust he offloaded his impregnating juice into Wendy's mouth, that's when he realised... she had swallowed it... A smile grew across her face but her eyes remained closed; she whispered, "It's funny you know, you thought I was sleeping...".
