I leave you with your stepmother, but don't fuck her

He had to leave the house for a few hours and warned his son: I'll leave you with your stepmother, but don't even think about having sex with her. and the warning made sense, because with a mature, busty woman as vicious as this one and with a son so horny, things could go wrong. but his girlfriend assured him that she would only give him a massage to practice the course he had taken as a chiropractor, nothing more. but as soon as she was alone with the boy and saw how hard he was to touch him, she couldn't resist and gave him a good blowjob, with those doll lips of hers.
