Mirror on the ceiling reflects everything in “quadratic function converter”: a woman on all fours, hair cascading, fingers working furiously between spread legs. “quadratic function converter” alternates angles—her face contorted in pleasure above, ass high and glistening below. She flips, back against cool sheets, knees to chest, giving “quadratic function converter” the perfect view as a thick toy stretches her open. Each thrust echoes in breathy cries until “quadratic function converter” freezes on the moment she squirts, mirror dripping with evidence of total abandon.
