No, it's too embarrassing.

The rest of the week and the next go about the same.

You and Chase sleep in separate bedrooms. He's an athlete and needs his rest. His Mom controls his entire life - when he wakes, what he eats, how he exercises, the number of miles he runs, the types of practice he does.

You find out later that she has an entire team on hire: A nutritionist, two coaches (one just for his backhand), videographer, social media manager, an orthopaedist, and a sports psychologist. Her days are endless consultations and planning for Chase's every move.

And you.

You are the subject of much discussion. The entire team has seen a substantial uptick in "beneficial behaviors". Chase is showing off for you. He is doing additional exercises, he is more focussed, he is trying harder at all points.

Of course, Mrs. Chamberlain doesn't mention any of this to you. This is all happening in the background.

And every day you reward him by sucking his cock... or letting you dry-hump your buns... or...

"What are you doing?" asks Chase, as you grasp the hem of your stretchy white (with pink trim) tennis shirt with your arms crossed and pull it over your head.

He has just completed his serve practice, getting four in a row with a minimum of 125 mph in a 6-inch box at the far left corner of the court.

Your tits spring forward, gloriously naked without their usual sports bra. You pull out a tube of KY jelly from your pocket (have have it handy all the time, these days, for whenever he needs a hand-job) and squirt a generous portion of it down your cleavage.

"You don't mean..."

"Oh, yes," you say, with a throaty growl. You drop a towel on the ground and drop to your knees before him. As you pull down his shorts and jock strap, you glance up at the second-story window where you see Mrs. Chamberlain looking down with approval.

Chase's member springs forth, hard and proud, and exactly the right height. You grasp it with your slippery, lubricated hands and then place it directly between your big (fake! but OH SO DELICIOUS - the doctor gave you the perfect pair) breasts and you squeeze them together around Chases's cock, creating a booby sandwich and then you use your abdominal muscles to move your chest up and down, giving his rod a hot overdose of titty love as it slides up and down through the woman-flesh-tunnel you've created for it.

Chase looks over and sees his mother watching, but he's too far gone to stop at this point. He grasps your shoulders and starts thrusting like a maniac, pressing his crotch into your chest.

Soon, he is closing his eyes and groaning with pleasure. You look down and see the cock head peeking out from between your boobs, just as it jerks and shoots a spray right in your face!

"OH, FUCK!" you both shout together - for entirely different reasons. Chase keeps thrusting and his cock keeps spurting, the cum shooting up between you and landing in your face, your nose, your eyes, your mouth and chin.

Finally, he settles down. Your whole chest is a gooey, disgusting mess.

"FUCK, that was good," he says, looking down at you.

You do your best to look up and smile, like the adoring girlfriend, but looking more like the slutty, horny, cum-covered, whore girlfriend you really are.

FINALLY, after two weeks of intense practice, Chase has a "warm-up" match. A third-tier tournament...

... and he WINS IT.

Easily.

Every match is straight-sets. He wins the final 7-5, 6-3, 6-1.

His opponent is not just beaten, he is DESTROYED.

After the final match, Mrs. Chamberlain arranges to have you naked in the massage room, like before. You are lubricated and ready to go. Chase comes in and RAVAGES you, he is sweaty and disgusting but smells LIKE A MAN, and he fucks you long and hard until you're sore and panting and you've both cum at least twice.

And then, after you've showered, there is Mrs. Chamberlain with her chastity panties to lock you back up.

This is it. It's three months later. Even though Chase has done a bunch more tournaments, building up his point total, you've not been allowed to fuck him. You give him daily blow jobs or titty fucks for good behavior, but other than that, there is almost no intimate contact at all.

"Let's keep our eyes on the prize," his mother says, laying down the law.

But FUCK, you are horny for Chase! You are both in such intimate contact, all day long, every day, that all you can think about is how much you want him to FUCK you, and FUCK YOU HARD. It's practically the only thing you can think about.

But now you're in New York, and that means it's the US OPEN. If Chase makes it to the Semis, his ranking will jump from Top 20 to TOP 10, and he will win ALMOST A HALF-MILLION DOLLARS.

And Mrs. Chamberlain has promised that he will get to sleep with you for an ENTIRE WEEKEND.

But more than that... if he wins the quarter finals, she will also consent to having him marry you.

And time is running out. There's only three more weeks left before the deadline specified in the will expires.
