In a dimly lit dungeon, two young, curvy lesbians, bound and collared, kneel before their Mistress. She teases them with a large strap-on, running it over their heaving breasts and down to their wet, quivering pussies. The girls whimper and moan, dreaming of a threesome where they'd take turns pleasuring each other and their Mistress. The Mistress, enjoying their torment, slaps their asses, leaving red handprints on their big, round buttocks. She then uses the strap-on to punish them, making them orgasm uncontrollably.
