With people nearby, they desperately try to keep their voices down so as not to be found out, but they are overcome with supreme pleasure... The thrill of "doing this in this situation, and possibly being found out at any moment" brings them even more excitement, and they writhe in agony while fighting the moans that escape, resulting in repeated quiet climaxes. This is a masterpiece that you will want to enjoy as you watch the lascivious eroticism of these women.
