We called out to a group of men and women on a summer vacation at the beach in Minami Boso! We proposed a "sexy Russian roulette handjob" where a man gets excited at seeing his female friend in a swimsuit for the first time, and the female best friends compete against each other! If you make the other person ejaculate during your handjob turn, you lose! Meanwhile, to encourage ejaculation, the other person doesn't touch his penis, but instead uses slutty play, such as kissing, slang, dripping saliva, nipple play, and toys! Look forward to this hot battle between women with semen and raw sex at stake!
