Not a game, but the sex of serious swimming partners is too intense. First, their libido is too strong, lol. They are sexual giants with endurance. Sex in slippery oil while wearing their usual swimsuits. Deep thrusting with a huge dick they trained with swimming into a crotch soaked with messy water. Finally, ejaculating inside the vagina so much that it seems to be coming out. Serina (20) & Riku (20)
