Trigger warning - this one's a bit off my norm. But that said, my interests are very broad. At the consent, request, and collaboration wtih a friend, tonight's fetish twist - "The Helper."
This is a very special, intimate, erotic role for the husband or boyfriend. Getting him hard for her, while she watches. Guiding his cock into her. Slowly, deliberately, with hubby watching, up close, as her lover's cock-head pushes inside her, past her lips. It's so erotic.
He helps sometimes; if the man's cock accidentally pops out, from too vigorous penetration, or if he's too close to cumming inside the wife, encircling his swollen ball-sack, gripping it, pulling, trying to delay the man from cumming in his wife's pussy/
You were warned.
