MISM-315 Convulsive incontinence deep throat

The deep throat piston we did made her very happy. She must have been so moved that the whites of her eyes were exposed and tears were streaming down her face. When I inserted it into her pussy at the same time, her lower body convulsed periodically like a machine, as if she was thanking me by saying “Thank you.” The problem is that when she gets deep, she squirts out of her pussy, but we don’t know how to stop it, so we just let it be.
