the Other sister was an adult in her middle 30s and the other one was in her middle 20s
And those sisters used to take a bath while the bOy's around,
one day his oldest sister shaved her pubic her while the other did'nt
and the bOy asked the one who shaved:
Boy: why did you removed the stuff there, and the other sister says; ask her! [being jealous]
Oldest sister: have you ever seen the grass grow on the busy road Wena!
and the other sister started to keep her private part very busy like no body's business from that day!
