Cate is showing two new girls, Masie and Rachel, round her gym. Beefy powerlifter Peter is already working out and isn't impressed by three girls getting in his way in the gym. However, when he lies on the benchpress he gets a great view of Cate's perfect ass in her skimpy shorts. The girls are busy learning how to use the equipment so Peter starts rubbing the front of his shorts as he watches Cate's ass. He then starts to get carried away and slips his hand down the front of his shorts - just as Masie and Cate turn round! The girls are furious that he has been ogling them and touching himself and Rachel grabs his arms and holds him down as the other two shout at him and prod at the bulge in his shorts. The girls say they are disgusted but soon want to see the contents of his shorts and pull them down as he tries to fight them off. The girls all hold him down though and laugh and poke at his cock, which is quite hard. They take turns to touch it and stroke it and are howling with laughter at how excited he has got. As the girls wank his cock, he soon gets too excited and has a massive orgasm right there on the bench!
