A dark part-time job trap awaits the high school girls who are lured by sweet words like “Make a ton of money in your spare time!” The applicant this time is Rinka-chan, a girl with cute earrings and huge G-cup breasts (!). “Is it okay if I just lie here?” That’s right, her beautiful ass and beautiful legs are stuck in a hole in the wall and restrained with chains. All that’s left is for her to cum from three customers! “Eh??” While she’s crying and having an unpleasant French kiss with a creepy old man, her pussy that’s popped out from the other side of the wall is licked and sucked, and made sopping wet with fingers and a vibrator. After she’s skillfully squirted with a vibrator, it’s time to squeeze out the raw cock. Semen is poured into her throat and tight pussy, and while she’s cumming like crazy with her ass twitching, she’s completely stored in a custom-made box with a hole. A wonderful human toilet is made!
