Your step-dad has been getting more and more upset about your grades in Uni. He paid for you to go to the best Uni his money can buy and now all of a sudden your previous good grades are plummeting through the floor.

He can't understand it! After all you have told him you are studying hard.

In a desperate measure to try and get you more focused on your studies and less on the parties at Uni he makes you move back home and asks his next door neighbour Ava to come and keep an eye on you while you study. Just to be sure...

You don't need a babysitter! You tell him this but he is adamant that you will thank him eventually.

Ava turns up and gets down to business. If business is watching TV full blast and distracting you!

You decide that you really can't be arsed with studying. And after all she looks all demure and innocent with that long dress of hers and sensible cardigan. All grown up. You reckon she must be your step-dad's age. Practically mature...

But you bet she hasn't had any cock for ages. You can just tell by the way she's acting 'relevant' but doesn't have a clue about anything...

And when she starts telling you off about how you're just a dumb junior you feel like you just have to let her know that you might be young but not where it counts.

And when you put her hand on your rock hard cock you can tell by the way her eyes light up that she can tell how much of a big man you are! So much that she can't resist the urge to stroke it until you cum...

Best. Babysitter. Ever!
