Roxie Sinner – Cumistry

Roxie is a curious student who wants to learn everything about sex. Her curiosity has slowly evolved into an obsession after hours of research watching porn. She wants to understand the nature of semen and how it works. That’s why she recruits Joshua, a fellow geeky student who can provide her with a sample. Joshua is a little unsure about the whole experiment, but Roxie won’t stop until she is cummed on–for science’s sake, of course!
