My beautiful, brilliant sister-in-law—the woman I have always admired—unexpectedly gets a job at a men's massage parlor. One day she asks me to be her practice client, puts me in paper briefs at home, and gets to work. What should be innocent training turns into an expert groin massage that hits every sensitive spot and leaves me rock hard. My self-control crumbles, and after I beg her to stroke my cock, the handjob and full-body massage practice escalates into creampie sex on the massage mat, a shower blowjob, and heated fucking. Her soaking-wet pussy cannot get enough of her brother-in-law's cock.
