Its excruciatingly embarrassing for Andrew to get erections

Its excruciatingly embarrassing for Andrew to get erections at school and hes always done his best to hide them. But since hes stark naked and the women are fiddling with his penis trying to secure the bandage he has no way of hiding his growing excitement. With all his might he tries to will his cock to go down, but it reacts to their stimulation growing bigger and bigger by the second.
