18-year-old gymnasts get double fucked by their coach

Two 18-year-old gymnasts are training with their coach in his apartment. The coach is a muscular man with a lot of energy to spare. He starts by showing the girls some of his moves and tricks, and then the girls take turns practicing on the floor. The coach then suggests they practice their flexibility, and the girls show off their flexibility by bending themselves into some very sexy positions. The coach can't resist any longer, and he starts to touch the girls' bodies and kiss them. The girls are very receptive to his advances, and soon they are all over him, touching and kissing each other. The coach starts to finger the girls' pussies, and they are all very excited. The coach pulls out his hard cock and the girls take their turns giving him blowjobs. The coach fucks both girls in the ass, and they both enjoy it very much.
