My tutor has huge tits, and that turns out to be the problem, because I can't concentrate on studying. I steeled myself and tried “If you let me feel your tits I'll get 100%!” — which did not go the way it goes in films. But my head was still completely full of tits, so I decided to dose her and fuck her. I handed her a drink with an aphrodisiac in it and it worked spectacularly: my tutor went into heat, turned into an absolute nympho who couldn't stand not having it, and went straight for my cock. I put my rock-hard cock in and took her properly from behind. Except we did it so much that studying was completely off the table afterwards.
