Sweat glistening, breasts bouncing, big-assed instructor Rui Shinomiya lifts barbells. Today too, she makes her students' dicks rock hard with excessive close contact. In thorough one-on-one training where no one else can enter, she devours erect cocks and screams with fierce piston thrusts. During oil massage, she has them grope her ass while jerking their dicks, and when they insert it right there on the bench, she shakes her whole body, tosses her hair wildly, and climaxes over and over. For some reason, this gym, which only gathers big dicks, is always filled with a lewd scent.
