The neighbor's adult video is too loud! Nao, who has reached the limit of her patience, goes to complain, and a filthy sex-crazed monster comes out of the stench-filled trash room! He drags her into his room and forces his dick, covered in smegma, into her, and even cums inside her! Even though her boyfriend is there, she is called out, puts toys inside her while wearing a school swimsuit, and is forced to lick a smelly dick while wearing a nude apron... She shouldn't have liked it, but... the stench causes a brain bug, and Nao begins to feel an addictive pleasure...
