Surprisingly easily actually.

Mary hands you a plate of eggs and bacon before sitting down next to you on the couch. Mark offers one to bag, who shakily grabs it and starts nibbling at it without sitting up, before sitting in his own chair and digging in with a moan. "Oh man I forgot how good you can cook." You take a bite of your own and moan as the light fluffy eggs and greasy bacon hit your palate.

Mary Smiles at you "Im glad you like it." She beams, before leaning over and saying in a conspiratorial whisper "I added a special ingredient to the eggs." She winks at you before resuming her eating. You now stare at your plate for a moment before looking at everyone else eating, and with a shrug you continue devouring the delicious breakfast.

Before you know it the food is gone, and setting the plate on the end table you slouch down in the couch and let out a sigh. Soon the rest of them finish eating and join you in bliss. Eventually Mark speaks up. "Hey sorry bout last night man, I know you like to drink milk when you are tired, and I completely forgot to tell you that I used the last of it. I was talking to Mary, and she had a wonderful idea. How about as an apology I give you her as your personal milk dispenser?" Your brain grinds to a halt. You had already forgiven him, its not actually that big of a deal, and... wait what?

You turn to Mary with a frown, but she is just smiling at you "Wouldn't it be great to have milk whenever you want it?" She asks in a cheery tone, her hands under her breasts lifting them up to appear even larger.

"Don't you have to be pregnant to lactate?" you sputter in confusion.

She just waves her hand dismissively. "Oh I already thought of that, although you can do that latter if you want. I went out last night and got a prescription to induce lactation, it kicked in this morning. I even put some of my milk in the eggs!" To your shock she peels off her shirt, and you can definitely see that her breasts look a little swollen. Behind her mark is just nodding and smiling. She thrusts her chest out at you. "Go ahead, try some!" You look around in confusion but Mark seems fine with this, and bags reactions don't count considering she keeps begging you to shove things in her.

Seeing your apprehension, Mary deflates. "Im sorry." she say tearing up a little. "You don't need a milk dispenser. I just don't have a job or a place to stay and I thought I could be useful here." Behind her mark is giving you a **** glare now.

Trying to regain some control of this outlandish situation you sputter "No, no, uh im sorry, You just surprised me." Mary perks up and smiles at you while she wipes the tears out of the corners of her eyes. "Yay! here, try some of my milk." you awkwardly lean over and take her nipple into your mouth and when you suck gently a trickle of sweet milk flows into your mouth. Its a lot creamier then you expected, but really good. when you suck a little harder Mary lets out a moan and you glance up to see her blushing at you. As you finish and release her, she bounces up and down and claps her hands before hugging you to her bare chest. "Yay, ill be the best milk dispenser you could ask for. Feel free to drink some whenever you want." She releases you and hops up. "Oh, I got something to celebrate this." she runs out of the room, some milk dripping onto the floor as she bounces a little too vigorously.

You just sigh and grab your napkin and plate and on the way to the kitchen mop up the spilled milk before it dries. After rinsing your plate you set it on the counter and head back into the living room and sit down again. Mark looks oddly pleased with himself. "I haven't seen her this happy in ages. Im sure she will be good for you." he says before getting up. "Anyway I gotta get to work, enjoy your toys." He leaves to his room and you glance over at bag. She has relaxed a fair bit, but with a start you realize you left that can in her. Reaching over you grab it and gently start pulling it out of her. She moans and arches her back a little as you pull it free with a pop and look at her gaping pussy. Its already starting to relax and pull back to normal. You shake your head in disbelief at the elasticity of female sexual organs and inspect the can for anything weird. Aside from the sides being annoyingly slippery the can seems fine, Heck its even pleasantly warm.

Popping the top you down some of the body temperature caffeine and after a few moments you feel it start to work at lifting the fog over your mind. Before you can take another sip though you hear the door open and Mary saying goodbye to her brother as he leaves.

Soon She comes skipping back into the living room wearing a headband with little horns holding her hair back. On her arms are some long gloves with a black and white dappled pattern that goes all the way to her bicep. Her legs have long socks that come up to just past her knees with the same pattern. The rest of her is stark naked and your poor confused penis stirs a bit as she cocks her hips to the side and asks. "Whadya think?" She runs a hand over her bare ass and down one thigh sensually.

"You are basically naked..." you say. Your cock finally decides it likes this and is straining in your pants.

Mary glances down at the tent in your pants with a knowing smile. "I'm dressed like this because I'm your milk dispenser, I thought a cow print would be appropriate. MOO." she says playfully while cupping her breasts. "You need to have access to my breasts whenever you want." she blushes as she hangs on the word for a moment. "A-and my P-pussy is available so you can feed me your milk whenever you want." she manages to finish with a wink. "Besides, the doctor said my milk will be even better after you breed me, and plus I wouldn't need to keep taking these pills. So any time you want, just plunge in there and empty yourself." "Please." She follows up quietly to herself.

you get up and she looks at you with hopeful eyes.
