Ruisa lives in an apartment building. She can no longer stand the dirty room next door, which she has always hated, and when she goes to complain about the smell, the resident, a muscular sports college student, drags her into his room and beats her up. Not only does he make her cum over and over again with his endless, virile thrusts, he also makes her smell his sweaty body odor, polluting her insides. In a trance state, he even cums inside her, pouring 30 shots into her uterus without pulling out.
