Two sisters accidentally see their virgin brother masturbating with a masturbator. While making excuses, the virgin brother sees an opportunity and desperately begs, "Please, just put this masturbator between your legs... please!!" He proposes a sex play, without caring about the consequences. Feeling sorry for the virgin, the sisters accept his proposal, but the penis that was originally inserted into the masturbator accidentally slips into her pussy... a divine raw sex scene!
