Most embarrassing for me was a completely no touch one where she made me watch it happen. She was holding me up in front of her with her arms under my upper thighs, facing away from her, and she forced my legs to spread out wide, and walked me over to a mirror. Then she started dirty muscle talk directly into my ear, and was mimicking taking me from behind, pounding in to me, and kissing and biting my neck, telling me she wanted my cum, and at some point I just let loose. I was humiliated and was apologizing so profusely, but thankfully she let me off the hook and let me cuddle for a while to regain my composure and then we went on with the session.
