A boring otaku who's an erotic manga artist receives a DM from a sexy-looking onahole saleswoman!
"Please test it for real." says the message, including an erotic selfie which ends up enticing him; When he meets the saleswoman at his place, a super slutty tanned gyaru showed up!!
Moreover, the pocket pussy was apparently molded in the shape of her own pussy...
After being told to try it out, of course he had no choice but to do it!
The slutty onahole seller also has him treat her like a real sex toy, letting him have whatever he pleases: everything from a blowjob, titjob, missionary, doggy style and even up to a creampie finish!!
