Jacob smiled, "I think I have an idea. We're going to turn you into a horny, hot chick."
Tim's eyes went wide. "What? No, wait!"
But, Jacob clicked the mouse just at that moment, and Tim was instantly replaced by a female version of himself. Because Jacob had clicked the aware toggle off, Tim was oblivious to the change.
"Jake, I just want to thank you again for letting me come over," said the girl who just moments ago had been Tim. "I've really been looking forward to spending some time with you... alone."
"Uh, Tammy?" said Jacob.
"Yes?" said the girl, who apparently was now named Tammy.
"Tammy, hold on just one second. I want to make a few quick upgrades." Jacob started selecting options for Tammy. First, he increased her breast size from A cups to D cups. Second, he thinned her waist out. Third, he increased the size of her ass and hips. Looking her over then, Jacob smiled at his work. His friend, Tim, had become a real babe. With her nice curvy figure, she could definitely make the cheer leading squad. Now this is payback, he thought. He sat there for a long moment just admiring her figure. Then, for the final change, Jacob increased Tammy's libido and gave her a strong attraction to him.
After that change, Tammy walked over to the bed and sat down on it. She smiled at Jacob invitingly and then unbuttoned the top two buttons of her shirt, revealing her ample cleavage.
"So, Jackey," she purred to him seductively. "How about we have a little fun while your folks are away?"
Jacob was a virgin, and he was reasonably sure that Tim had been one as well. But, at that moment, all thoughts of Tim were replaced by the thought of sex with this gorgeous nymphomaniac on his bed. He didn't care who she had been only seconds ago.
Overcome with lust, Jacob rushed from the computer and met Tammy at the bed with a deep tongue kiss.
"Hmmmmm," she moaned. "I want you inside of me," she said when their lips separated.
Hearing her say that, a thought came to Jacob. He absolutely wanted to be inside of her just then (his raging boner was proof enough of that), but this was a punishment after all. Why not tease her a bit first? There was plenty of time to have sex later. For now, he wanted to humiliate Tammy.
Jacob pulled away and sat next to her faking as though he was uninterested in sex. "Eh," he said. "I dunno."
Tammy looked absolutely shocked. "Come on," she said. "Don't you want me? Don't you want these?" She finished unbuttoning her shirt and then removed her bra.
Jacob stared a moment at her large, perfect breasts but then looked away again and said, "Eh, they're nice and all, but I was thinking I might just want to watch some TV instead."
Tammy was momentarily dumbfounded. She couldn't believe that the object of her lust, Jacob, would turn her down. "No, wait!" she protested. "Please, I need you right now! Please, fuck me. I'm begging you." Then an idea came to her. "I know! You can fuck me in the ass. You know, doggy style." She climbed onto the bed and stood on hands and knees, mimicking a dog as best as she could. "See, we could fuck while you watched TV then."
Jacob smirked at the idea that this super-hot babe on his bed was begging him to fuck her in the ass.
"Bark for me," he said.
"Arf, Arf," barked Tammy obediently.
Jacob thought about it a moment and said, "Well, if we're going to do this. I may as well fuck you up front. That way I can play with your tits."
Tammy smiled. She was overjoyed. "Yes! Awesome!" She flipped over onto her back and then pulled off her skirt and panties, leaving her totally naked. "Come and get them," she said and pressed her breasts together to create a line of cleavage for Jacob to ogle.
Jacob smiled. This was the first girl he had ever seen naked in person, and she was beautiful enough to be a model... or a porn star. "Tell me you'll do anything I say."
"I'll do anything you say," Tammy replied. "I promise. I'll do anything for you, if you'll just make love to me."
"Anything, really?" said Jacob, who was relishing his absolute control over this total babe. He thought a moment about all the possibilities this situation presented. Then, one thought occurred to him about what to do next.
"Well then," he said. "I have an idea."
Tammy looked up at him with anticipation.
"I want you to..."
