Task for the man
She may end up on the receiving end too if you're patient. Lie on your stomach with a pillow underneath you so your ass is raised. She will hit your ass with a belt until you say the safeword you must agree on beforehand. But if you hold out, she'll take your place. The game continues until one of you stops it with the safeword. She has 10 attempts. The loser fulfils any wish of the other partner. Stay strong!
