In a quiet library, the target is a fair-skinned female student who came with her boyfriend. She is approached from behind while choosing a book! She is forced to cum over and over again in a situation where she can't even make a sound, and then she is forced to be naked! Covered in oil and embarrassed! From the sticky and humiliated slit, stringy love juices flow... Carried away by pleasure, she goes crazy with forbidden sex that betrays her beloved boyfriend! *This work is the same content as part of NHDTB-923 "Library 30" scheduled to be released around June 2024.
