Yes

You can't resist this long dick, so you nod and reach out your hand to touch it. Your own cock twitches and starts growing by just touching another mans cock. Your mind wants to stop you, because YOU ARE NOT GAY! But your body can't resist. Your hand starts stroking your professor's cock and it's becoming even bigger. You just stare at your hand stroking this huge dick and your mind is completely empty. "You can also suck on it if you like." he tells you. This gets you out of your trance. You quickly pull away your hand and answer: "No I don't want to. I have to go now." "Your body doesn't seem to think that." says your professor as he looks at your rock-hard cock. He puts his hand on your head and tries to push you down to your knees.
