He caught his sister masturbating and helped her by fucking her

The other day, his sister's bedroom door was ajar and through the crack he caught her jerking off with a porn video in front of her. wow, he was impressed with her sister's shaved cunt and in that moment he wanted her like a brother shouldn't want her. the fact is that in the end he went into her room, at first just to make fun of her, but the truth is that he was very horny and thought she wanted him to help her anyway. at first he just put his fingers in her, but seeing that that wonderful little pussy was so wet, he opted to put his cock in her, which was what she really wanted.
