First time anal training

As the video begins, we see a nervous and inexperienced man, Alex, being led into a dimly lit room by a dominatrix, Mistress. She instructs him to remove his clothes and kneel on the cold hardwood floor, facing the wall. His heart races as he obeys, anticipating what's to come.Mistress returns with a long, thick black dildo, which she lubes up generously. She stands behind Alex, running the slick toy up and down his spine, teasing him. She pushes the dildo between his cheeks, spreading his tight anal opening."Relax, this won't hurt," she lies, as she slowly pushes the dildo into Alex's ass. He gasps in pain, his body tensing up. Mistress holds him firmly in place, pushing the dildo deeper as he gasps for air, his legs trembling from the sensations.
