Under the cascading water, Ayumi's perky breasts glisten as she guides M-kun's massive, veiny cock into her mouth. She worships it, her lips tight around the shaft, tongue flicking the sensitive head. M-kun's grunts echo off the tiled walls as he thrusts into her warmth. Their bodies, slick with water and desire, press together. Ayumi's moans vibrate around his cock, pushing him over the edge. He explodes, his hot cum filling her mouth, spilling down her chin, a testament to their passionate exchange.
