Personal trainer fucks two teens in a group sex session

The scene opens with two teenage girls, both of whom are clearly uncomfortable, sitting in a dorm room. A muscular man, who is clearly a personal trainer, enters the room and immediately begins to put them through their paces. The girls are clearly unfamiliar with the exercises, but the trainer is determined to push them to their limits. As the workout continues, the tension between the girls is palpable. It becomes clear that they are both attracted to each other, but they are too shy to act on their feelings. That is, until the trainer suggests that they engage in some group sex. At first, the girls are hesitant, but they quickly give in to their desires. The trainer takes the lead, showing the girls how to pleasure each other with their tongues and fingers. The girls moan and scream with pleasure as they reach a series of intense orgasms.
