The chick blindfolded the guy and he didn't even know he fucked the mature stepmother

The girl locked herself and her boyfriend in the bedroom to have sex with him and blindfolded him first so he wouldn't catch the switch. At that moment, the bespectacled stepmother, who had long wanted to fuck, came in and she took the boy's cock into her mouth. He didn't even suspect what was going on and fucked the other broad while his beloved watched.
