Natsuki Hoshino picks up a runaway girl on SNS and picks her up in an aphrodisiac sex potion, turning her into a meat urinal that allows her to cum until her cock is satisfied.
I ran away from home. That's why I asked for help from an old man I didn't know much about. I'm just letting you stay at my house for a while, so it's not dangerous...right? A girl whose body is all grown up, but her heart is still immature. She was noticed by an old man who was looking for sex, and he taught her how to feel good in every inch of her body. Little by little, the girl, who she knew nothing about, was starting to lose her footing.
