He squeezed his eyes shut. The comforting warmth of the cum spread through his body, and his tense muscles became loose and relaxed.

Stan stopped thrusting with his hips, but left his cock buried deep in Fred’s ass. Every few seconds it spasmed again, sending a shiver up his spine.

"My my, that was the best fuck I had in a long time. What’d you think of it?" Stan said. He was panting and stroked Fred’s ass with one hand.

Fred looked at Kate. Her mouth hung open and she was rubbing three fingers in and out of her pussy.

"All right," Fred said, but his voice was hoarse and muffled by the pillow.

He was almost disappointed when Stan pulled his cock out of his ass. It left him with a cold, empty feeling, and some cum that leaked out. He gave his ass one hard smack.

"You’re not a virgin anymore. How’s it feel?" he said, and lay on the bed on his side beside him. He glanced at Kate and they grinned at each other.

"It’s ... weird," Fred said.

He rolled on his back and stared at the ceiling. He felt different, like he had been transformed into a different person. Would he ever be able to change back?

Stan put his hand around Fred’s huge erection again.

"Yeah, I know. I remember the first time I got it up my ass. I’ve never been the same since."

He laughed and Kate laughed with him. Fred groaned softly. He didn’t want to be different. He didn’t want getting fucked in the ass to feel so good that it made him consider the idea of doing it again. He wanted to be the same old guy who found hot chicks so irresistible.

Fred looked at Kate. She was smiling and nodded, as if she was making the decision for him.

"No. How was I supposed to know that?"

"Because I drop hints about it every time we’re together."

"Why didn’t you just ask?"

Stan rolled his eyes and put his hand on his hip.

"Oh sure. What was I gonna say? Hey Fred. I hear you got a big cock. Wanna shove it up my ass? Like you would’ve said yes to that."

Fred shrugged. "You never know."

Kate reached over and grabbed the tube of KY jelly.

"You two just keep arguing about it. How about if I help you out with this?" she said.

She squeezed a big glob of grease on the head of Fred’s hard cock like she was putting whipped cream on a sundae. Fred was leaning back on his elbows and his cock stood straight up, bent over to the side by its own weight. She closed her hand around it and pumped up and down, spreading the grease over the entire length of the shaft. He looked at Stan.

"I’d love to," he said.

"Love to what?"

Fred swallowed hard. He never would have believed he could say what was
