It's a swim club camp with only me. The last day is the usual big cleaning. Everyone cleans the bathroom in swimsuits. Then, I accidentally get super excited by the protruding butts of the swimsuit girls I thought I was used to! And then, I thought my erection would be discovered and it would be a big fuss! But... the girls who had a lot of stress from practice couldn't suppress their horny feelings and came flocking to my dick! The super tight swimsuit figure, if you look closely, is incredibly lewd and my tension also skyrockets! I do whatever I want, such as sliding the swimsuit's crotch area or putting my hand in from the side and rubbing their breasts... I even experience ejaculation in a swimsuit like an erotic manga! A terrible camp full of only practice turns into the best camp!
