[Hakomaru] Kenkyuu Taishou ~Rizu Chousakan~ (Experiment subject ~Liz the investigator~) [Kuraudo]

Hiyori and her boyfriend expect a quiet Christmas date, but her coy hint about one more place to visit leads them straight to a hotel bed, where she eagerly services him with her drool-soaked mouth and teases that he's still loaded before pulling a school swimsuit on to ride him through climax after climax. Their playful, affectionate banter carries them from the bedroom into a shared bath, where soapy groping and his growing arousal against her butt turn a simple soak into an excuse to extend their special day. Sweet couple chemistry meets relentless physical indulgence as the two trade gasped confessions and greedy touches well past checkout time.
