Sissy-Fuckpucker's trainer, a dominant shemale, trains her sissy in the art of humiliation and gaping. The trainer's colossal cock, sheathed in a thick strap-on, is pressed against the sissy's tiny, puckered anus. With a cruel grin, the trainer pushes in, feeling the sissy's asshole stretch and widen around her. The trainer fucks her mercilessly, each thrust filling the sissy's ass completely, making her gap even more. The trainer pulls out only to let the sissy catch a glimpse of her own gaping asshole in the mirror, before slamming back in, making the sissy take every inch of her massive cock.
