Next position, in her hands

Naomi stood up, taking Victor's cock in her hands. She guided his body to one side of the tub, and stood behind him, the cold water splashing on her back. She reached her arms around his waist, and took his cock in her hands. She began stroking him from this angle.

Naomi reached to the shelf of soaps and lotions, and took up a small green bottle. She squeezed some into her hand, and brought her hands back around to Victor's cock. She rubbed it with the lotion, and he tensed up. "What is that?" he said.

"Ketchup," said Naomi. She paused for a moment and then laughed. "Oh god, what if it were ketchup?" She laughed again, harder. "No, it's a moisturizing body wash that has an intensity of mint, menthol, and a faint trace of the oils found in habanero peppers. The menthol cools the skin while the pepper oil inflames it."

"Have you ever put this on anyone's genitals before?"

"Ooh, do you want to be the first test subject?" As she stroked his cock, she began to pretend to be on some kind of television drama. "Star log twelve thousand seven hundred and three. Captain Doctor Naomi here, the invasive subject from Planet Rando Plumber is responding well to the pepper oil treatment. Only time will tell if the desired effect can be reached before subject deteriorates beyond recognition."

"My god, you are the hottest and weirdest girl I have ever seen."

"I have definitely put this lotion on other genitals, if by 'other' you mean 'mine' and if by 'definitely' you mean 'once a few days ago to see what it felt like.'" She paused. "And it felt amazing, by the way."

She continued caressing Victor's cock, which was hardening up very fast. "I'm getting the vibe that it's working for you too. You got hard in a fucking hurry."

He took a breath. "Honestly, I kind of think it might be the oil. I've never felt this aroused."

"Sure, it's the oil. I mean, you're getting jacked off by a fucking 20-year-old Asian chick who has perfect tits and a sex drive unknown to man, but yeah, let's say it's the oil."

She continued to masturbate his cock, and she felt his body pulse against her. He put his hands behind him, and found he was pressing back onto her stomach and breasts. "You want me to stop?" she asked.
