"I'm trying to escape not have sex with you Lisa! We need to get out of here before the nappy's used." He press his hands against the nappy just above Lisa, trying to slide him self up. But all he manages to do is shift his now erect cock so its pressing against Lisa just a the opening of her pussy, grabbing his shoulders she pull her pussy down on to his cock impaling her self.
