My brother and I are close. We are twins and we share an apartment together. My brother lets me watch him masturbate. He lies naked on his bed with his legs wide apart in the air and he strokes his cock. He's not circumcised, so he pulls his foreskin down before stroking his cock. The area under the foreskin is very sensitive, so he moans a lot when he strokes his cock. He makes weird moaning sounds (ohhhhhhhh, sssssss). His cock is big during erection, but it's a little crooked. Sometimes he rubs the tip of his cock. When he's close to cuming, his moaning becomes high-pitched (almost crying) and he tells me "my milk is cuming" or "my sperm is cuming." Before he squirts, he screams and cries, and then he squirts out his milk. He usually squirts out a lot of milk. He always keeps stroking his cock until all his milk is out. My brother masturbates quite often. Masturbation is very emotional for him (I can tell by the way he masturbates).
