WAAA-681 | I'll make you feel good for free. My dream sister-in-law started working at a men's spa, and I became her practice partner; a risqué groin massage pushes my self-control to the brink. Rima Arai.

My older sister-in-law—a stunning beauty and top student whom I’ve always admired—has started working at a men's spa...!? One day, she suddenly asks, "Will you let me practice on you?" and proceeds to practice spa techniques on me at home while wearing nothing but paper panties! I expected a wholesome service, but her incredible intuition and rapid improvement led to a risqué groin massage that hit every erotic pressure point—making an erection absolutely unavoidable!! My self-control crumbled instantly...! What was supposed to be a handjob and close-contact massage practice session—fueled by my fully erect cock—escalated into a wild, lust-filled encounter featuring creampie sex and a shower blowjob! Her soaking-wet pussy was absolutely ravenous for my cock!
