Close-up sex secretly in the futon with my frustrated brother's wife. Pressing her sweaty tits against each other's hot air, she drowns in deep pleasure with the sticky slow piston. In the intimate space of just the two of us, we keep our voices low as we repeatedly climax, and the inside of the futon is enveloped in the sticky sound of genitals rubbing together, and the heavy sighs that keep us from moaning. I hid it in the futon or curtains so that my girlfriend's brother wouldn't find out about our affair.
