Of course.

"Sure," Lily said as she reached for his erection. "You can fuck me."

Suddenly Lily's arm dropped and her gaze went blank.

"Lily?" Marked asked with concern.

"Don't worry about her," Jen replied. "Remember, we can change her with our thoughts. I just blanked her out for now. I wanna try something. Towel off and give us a minute, please."

"I thought I was about to get laid," Mark grumbled as he quickly dried off and left the bathroom. Not sure what to do, he got in bed nude and waited for the pair to emerge. After a few minutes, Jen stepped out clad in only a towel.

"Where's Lily?"

She grinned. "It's a surprise. I think you'll like it. In the meantime, though, I figured it'd be a shame to waste good dick on someone who doesn't - who literally can't - even want it." With that, she opened the towel to reveal her form to him.

His eyes widened as he took in Jen's body. Her full, pert breasts swayed gently, her nipples hard from a slight draft. Her abdomen was perfectly toned and smooth, leading down to a neatly trimmed thatch of hair between her thighs. He stared for a second before collecting himself.

"Oh my God, Jen, you're like a supermodel!"

She chuckled and laid down next to him. "This body is exactly what you want. I'm perfect for you because you shaped me. Now let's put it to some good use!"

With that, she reached one long, slender arm down and began to slowly tickle the underside of his already rock-hard shaft. Mark gulped and leaned in to kiss her, which she passionately reciprocated. She pulled him against herself and the feeling of her taut, supple breasts pressed against his pecs made him grunt with desire. His member brushed against her thigh and she let out a soft moan.

"Yeah?" he asked tentatively. For all the changes they'd been through, this was still his study buddy. He wanted to be careful.

"Yeah," she laughed huskily. "More!"

She rolled over to be on top of him and sat up. As she shifted her weight, he felt himself slide effortlessly into her, causing them both to cry out.

"Oh, my God," he panted. "You're already wet. This is- oh!"

Jen startled him by pulling him up so that his face was buried in her chest. Without thought, he began to greedily kiss and suck at the area between her breasts. She moaned loudly and hooked her arms around his back, pulling him even tighter against herself. She was bucking wildly, his cock ramming in and out of her with an ever-increasing tempo.

"Oh fuck," he said wildly. "I think I'm-"

His words became inarticulate cries as he was suddenly pumping his seed into her. Jen cried out in unison with him, arching her back so quickly she sent drops of sweat flying across the room. The air was full with the smell of musk and sweat as Mark finally felt himself relax, slowly melting into the bed with his dream woman on top of him. She leaned gently onto his chest, her breasts hanging inches from his face, and sighed deeply.

A moment passed. He smiled adoringly at her and she returned it.

"So what's the surprise with Lily?" he asked, still catching his breath.

"What fun is it if I tell you?" she asked. "Why don't you guess?"

He shrugged. "I have no idea what you're cooking up with her. Is it gonna be some kind of weird mindfuck?"

She smiled. "You have no idea."

He reached up to gently knead her right breast. She sighed at that and threw her hair back. He tried to think of what she might have done with Lily that would be such a surprise. Suddenly, something occurred to him.

"Hey Jen," he asked, his fingers idly tracing circles on her bare thigh. "Can you think of a random number between one and ten?"

She laughed, her face already starting to shift back to Lily's. "One."
