Ayumi, the naughty girlfriend, gives M-kun a sensual testicle massage, leaving him squirming and leaking pre-cum. Her delicate touch on his sensitive balls drives him wild, as she teases him, bringing him to the edge of ecstasy. She expertly uses lube to glide her hands over his throbbing cock and aching testicles, making him beg for release. Ayumi, however, enjoys the control, prolonging his pleasure, and denying him a quick handjob.
