NHDTC-175 A flat-chested girl tries out wearing a men's swimsuit. At the local pool, a guy with a big dick finds out she's a girl and cums inside her...it was the worst!! - Kisaki Nana

Two close female friends compete in a test of embarrassment! They take on a 'men's swimsuit challenge' they found online! They borrow clothes and a swimsuit from a male friend and head to the local swimming pool! This boyish girl shows off her flat, round breasts! I wonder if she really looks like a boy... (sweats). They talk to the other customers, swim, and the embarrassing mission escalates!! And then, in the end, they find out that they're cross-dressing...?!
