Fucking your sister

"Please fuck me." is all she says, as her breasts continue to enlarge once again, this time stopping once her breasts are twice the size of her head, doubling from what they where last time, since her previous size was now average, and still having to deal with Gigantomastia, as well as even higher than normal milk production from the other issue you gave her, making her normal milk output at around 4 gallons per day instead of the average 2 gallons per day.

You look at her, and decide to take some pity, ask her "Since you have been so cooperative, would you rather go back to the breast size you just where and have no issues from the weight of your tits, or stay where you are, and orgasm easily from nipple and breast play?" squeezing one of her nipples through her shirt, releasing some milk, and making her shirt wet.

She wiggles, rubbing her pussy through her shorts, and moans from you pinching her nipple "The first one please, can you fuck me now?" she asks desperately.

"Sure, get on undressed" you tell her, slipping down your own shorts, and taking off your shirt. Once you're undressed, you look down at your naked sister, her breasts swollen and taut, slowly leaking her freshly made breast milk. You push your sister back, making her lie down on your bed. You bend over, laying on top of her, feeling her warm soft skin make contact with you. You grope her breasts, she gives out a half yelp, half moan "Be careful, I'm sore when I'm this full." she says. You lean down, latching onto one of her nipples, and start to suckle.

"Wha- what are you doing? Why are you drinking it?" She struggles to ask between the moans.

You let go of her nipple, letting her breast settle back down as milk freely flows from her "What? People don't drink it? That's not right, would you rather breast milk have replaced cow milk in all forms of dairy due to how delicious and nutritious it is, or flush it down the drains as a form of body waste?" you ask her before diving back to your liquid breakfast.

"Well the first one, no since in it all being wasted, right?" she replies, one hand holding your head to her breast, and the other bringing the other one to her mouth. As soon as she answers your question, you immediately taste a difference in her milk. It changes from a watery, bland taste, to a thicker, richer taste with a brilliant texture and flavor profile.

As you suckle at your sisters nipple, you stroke her hair with one hand, as you guide your penis to her pussy, resting the head against her entrance. You start to rub the head of your dick onto her slit, causing her to moan. You pull back a little, and thrust into her. You feel her contract onto your dick, as she lets out low pitch moan, and milk explodes into your mouth. So much milk erupts from her, you let go, **** a little from the **** of the milk pushing down your throat. You face is given a shower of milk as her milk shoots up into your face. You pull her other breast from her mouth, letting both breasts lay naturally on her. You grasp her hands into your own hands, holding them high above her head, nearly touching the headboard. This causes you to straddle her fully, you kiss her deeply. You feel her breasts squishing into your chest, the pressure causing milk to be **** out of her breasts, covering the both of you and the bed.

You maintain this position for what feels for ever, every few minutes, bringing your sister Zoey to orgasm. Finally, after her 5th orgasm, you feel your own rising up deep inside. You slam yourself one final time into her, you feel your sister contract around you one last time, her breasts giving their final pushes before exhausting their supply, and you cum deep into your sister, your lips locked together, both moaning into each other. You roll off of her to her side, she turns to spoon into you. You both lay on the bed, arms wrapping around her, your hands playing with her nipples, even though her milk tanks are empty. Once your post-orgasmic haze lifts, you realize what you just did, came in your sisters pussy.

You go wide eyed "Oh fuck" you manage to say.

"Yes?" you hear a meek reply from Zoey.

"Zoey, would you rather society to be unfazed by ****, and any babies from **** be perfectly fine, or would you rather women be completely and totally subservient to men?" You ask her.

"The first one, duh." she replies quickly.
