After a fight, Gai Tendo is posing in the bathroom when Little Mac interrupts him. Mac wants to test Gai's strength, so he pummels his abs for awhile before throwing him onto the bed for a much harder ball bashing workover. Gai holds out as long as he can, and gets a boner pretty quickly. Eventually Mac pulls his trunks down and starts jerking him off while continuing to bash his balls. After he cums, Gai think's he's in the clear, but Mac continues to torment his sensitive dick.
