Coach and student. During a one-on-one overnight training camp for the track and field club, the coach's sexual desires run wild in the face of the defenseless, healthy, and bouncy buttocks of his student during training! Ignoring the bewildered student, he kneads her peachy buttocks through her training clothes, sniffs them all over, and rubs his dick against them! Using his middle-aged man's technique to play with her firm ass, he attacks her until her resistance weakens, and then… inserts his bare penis! He pushes her buttock flesh aside and violently pistons his erect dick into her slender body! He cums deep inside her as she is exposed and impregnated! He continues to fuck her over and over again, transforming her into a slutty track and field girl who squirts during orgasms!
