[Kise Itsuki] Uso, Ichiban Oku made Sounyuutteru... Kare no Kouhai kara Ikasarete... Uwaki SEX de Ochiru Yoru 1 [desudesu]

Yuzuki Tanaka, a devoted girlfriend with soft, voluptuous breasts and a trembling, highly responsive body, finds her quiet evening upended when her boyfriend's pushy kouhai Rei Satou strikes up a conversation and refuses to take no for an answer. His teasing quickly turns hands-on, with insistent fingering and intimate touching that leaves her flushed, leaking, and begging him to stop even as her body shudders with unwanted pleasure, all while she desperately tries to keep silent as a friend calls from just outside. Torn between loyalty and the overwhelming sensations he forces upon her, Yuzuki is pulled into a tense night of cheating and coerced ecstasy that threatens to make her fall for the betrayal itself.
