The bisexual couple, kneeling side by side, are at the mercy of their femdom trainer. She commands, they obey, their bodies responding to her every touch. She runs her fingers along their lengths, feeling their growing hardness. She lubes her strapon, pressing it against their tight assholes. They gasp, their bodies tensing before relaxing into the unfamiliar sensation. She pegs them, slowly at first, then faster, harder, watching as they squirm and moan, their faces contorting with pleasure and humiliation, pushing them towards a prostate orgasm they never knew was possible.
