In a dimly lit, soundproofed room, a masked man engages in a solo CBT session with a menacing dildo. He binds his cock and balls tightly, enhancing every sensation as he pushes the silicone intruder into his tight ass. He gasps, feeling the dildo's unyielding pressure against his prostate. He fucks himself harder, his bound cock aching for release. His body tenses, his ass clenches, and with a final, muffled cry, he comes undone, his cum spilling out onto the cold, hard floor.
