Mr Harkin may be the current Headmaster, but in a few meanings, Susan could easily ravish him his title. And as a role model, many students could certainly learn a few tricks from the lady. He told her so as she enthusiastically embarked on a tasty endeavor of cock teasing and sucking, very successfully. This woman was to be treated very seriously, and what an asset to this incredible school!<br/><br/>"<strong>Susan, I will certainly ask for your help as demonstration is indeed a very efficient training tool ----mmmh....---- and your tongue doesn't leave anything to chance, a stark contrast with what my student...</strong>" She let his balls go with a "pop" and went to her bed, on her back, her face ready for a brutal face fuck. He really wished Cassie would be here to check and take some notes. "<strong>You just would be the perfect assistant, what a team we would make both of us</strong>" as he positioned his cock between her opened lips.<br/><br/>God she was looking good and sexy. He groped her big breasts and pulled her nipples high, and slapped them across a few times, then he gave a hard slap on her pussy, her tiny panties had managed to disappear between these beautiful creases, and he felt between two fingers her protruding lips. She was already trying to suck him in deeper. He took his cock in hand and teased her a bit, rubbing its head against her cheeks and nose "<strong>you naughty smutty Susan, I will gladly fuck your beautiful slave mouth.</strong>" Instead he played the bastard for a bit and used it as a punishing stick to slap her left and right, and then he pushed it inside, and deep, and a bit deeper, reaching her throat, his balls sweeping her nose.<br/><br/>He began to move in and out, slowly, and his right hand reached for her pussy again, to give it few hand palms here and there, while her mouth felt so good, with her tongue working its way out to reach his balls. He went out to give her some air and he grabbed her babydoll and wrung it under her waist, it didn't hide or suggest anything anymore, it was just a tight piece of fabric he was now using as leverage to fuck at his heart's content the mouth and throat of this beautiful sex-goddess.
