One week later...

You wake up in Maddie's apartment. It's been a week since your study session in the library, and you're feeling... drained. You love what you've done to Maddie. Your relationship has progressed smoothly, and she doesn't seem to mind the changes either, but there's only so much semen one man can produce.

As the sun lands across your bed, Maddie begins to stir. "Good morning," you say.

She's up and getting ready for class within minutes. She has a breakfast of cereal and (actual, literal) milk before getting up and walking to the cupboard.

She gets a glass and tosses it onto the bed, where you lie and watch her. "I'm gonna take a shower and then brush my teeth, okay?" she says.

"Alright," you respond.

After only a week, it's getting to be a little too much. There's no way you can sustain this habit of hers. Should you reverse the changes you've made? Use the app to find an easy way out of this codependent relationship?

Not necessary, you think, not yet. You can always back out of this situation later if you want, but you're enjoying the new Maddie, and you really do want to please her in any way you can. So you add a rule, but this time to your own profile, under the section labeled "Physiological":

His body produces as much semen as is necessary to satisfy his girlfriend's requests.

"Hey, babe?" you say, setting the phone back on the endtable. "Can you help me with this?"

"Can I take a shower first?" she calls back from the bathroom.

"It won't take long, I promise."

"Alright, alright." She comes out, having already stripped down to her panties. You hand her the cup, and she bounces up on top of you. "But you'd better fill it all the way up," she adds jokingly.

Maddie folds the covers off your body and pulls your cock from where it lay resting. Holding the cup on your belly, right at the end of your penis, she puts her mouth on your balls and begins to work. Using a combination of her hands and mouth, she strokes from your balls to your shaft, teasing you and allowing the pleasure to rise within you. But even though she's an expert at this, she's not doing it for your pleasure this time. This time, she only wants what's inside you. In a couple minutes, her tongue has brought you to the point of orgasm.

But something's wrong: once the cum starts flowing, it doesn't stop when you expect it to. Instead, it pours out of your dick like water from a tap!

You remember the rule you've just written and groan internally. "His body produces as much semen as is necessary to satisfy his girlfriend's requests." As it happens, your girlfriend just requested that you fill the entire glass with your cum.

"Woah, holy shit!" she cries. Her mouth hangs open like he's hit oil, which, from her perspective, she has. For half a minute, you feel the fluid pulsing its way along your shaft and out the head until finally, after the longest orgasm of your life, you lie still again.

You've closed your eyes in fear, only now to open them again and look at what you've done.

"Actually, are you okay?" Maddie says. "This much cum isn't normal, is it?"

"Don't worry about it," you say. "But you'd better use it while it's still hot."

"Right!" she says, and she skips off to the bathroom. There, as she does every morning (and will continue to do until you erase the rule telling her to do it), she dips her toothbrush in the glass and brushes her teeth with your semen.

"There's so much left over!" she says. "I can totally just pour the rest into my water bottle!"

She does just that, pouring your semen into the bottle and filling the rest of it up with water. She showers, gets dressed, and heads for the door. As she's on the way out, she turns back to you.

"Thanks!" she says, taking a big swig of cum water before running off to class with her bottle in hand.
