As summer approaches, stepsisters Lexi Lore, Kylie Rocket, and Stella Luxx are drawn to the pool like bees to honey. They love lounging, gossiping, and soaking up the sun. But there's always one buzzkill: their nerdy stepbrother. Decked out in his dorky swim gear with a life preserver and armbands, he's the last person they want to string up out with. However, the girls determine to give him a chance and invite him to play ball. He's hesitant, clinging to his safety gear like a life raft, but they manage to woo him. However, when they attempt to remove his gear, things go awry. He stumbles and falls into the pool. The ladies realize that he can't swim. They rush to his aid, pulling him out and attempting to revive him. Little do they know, though, that the stud is not as plain as he seems. Being ideally aware of everything, he determines to train Lexi, Kylie, and Stella a lesson. As they lean in to perform m2m resuscitation, they feel a surprise in his trousers - an erection. One of the femmes is surprised that such a timid guy could have such an extreme penis. Her lips instinctively budge toward his penis. In that moment, she decides that this is the hottest way to save her stepbrother. She embarks to suck him, and the other gals go wild and decide to join in. After the killer manstick has been carefully polished, he can no longer pretend. He decides to thank his rescuers in a way they deserve. The stepsisters can't hide the fact that their vaginas are running in rivulets with slit juice as they wait for such a killer man-meat to slide inside them and bring them to mighty orgasms. The stepbrother approaches this fresh task with passion, plumbing the pranksters so stiff that each one shakes with orgasm. He ends his job, letting out an extra-large flow of super red-hot cream onto their fantastic faces. It looks like this pool soiree will go down in history as the greatest XXX!
