You get creative, then have a little heart-to-heart

You take one more big gulp of milk before letting the nipple pop out of your mouth.

"M-mom," you belch, "come here."

Sierra tries to move her tits out of the way so she can lower her face to yours, but you latch onto them with your hands to hold them in place.

"Not you," you growl, "you keep these fat jugs where I can suck them. I mean my actual mom!"

Your mother comes running -- well, crawling -- up the table to you, stroking your chest lovingly to let you know where she was. "I'm here, John. What do you need?"

"Sierra's milk is so warm and creamy, I wanna feel it on my cock. Get a nice big mouthful from her other teat and give me a blowjob with it."

She blinks for a moment at this unusual request, before remembering what Caitlin just told her. This is your condition. You know what you need, and it's her responsibility as your mother to give that to you, no matter how strange it may seem.

"Yes, sir!" she answers at last, climbing over to the other side of you so she can reach Sierra's free side. She watches as you go back to sucking and tries to copy your technique as much as possible.

Sierra shivers slightly. "Mmmm, I've never had them both going at once... It's really nice..."

Through the tut-tut-tut of your and your mom's breastfeeding and the slapping of your sister's ongoing handjob, you hear a rhythmic shlick as your former babysitter-turned-nursemaid starts masturbating under the table. Before long, though, your mother comes loose from the other tit and hurries, cheeks bulging, down to your crotch again. She lines up her tightly pressed lips the head of her cock and taps out a three, two, one warning against your thigh before plunging down onto you as quickly as possible to keep too much from leaking out.

The feeling is incredible. The warm milk sloshes around in your mother's mouth as she moves back and forth, and she maintains an insane level of suction to create a seal between her lips and your shaft. A little bit of it does slip out, of course, and it runs down your balls is sticky white trails. Caitlin sees this and jumps in, licking and kissing your balls as they clinch.

You hold out for as long as you possibly can, but this wonderful blend of textures around your shaft has you pumping a load down your mother's throat in no time. You don't even think about warning her, but she gulps down the copious amounts of breast milk and man milk at the same time. She just keeps sucking the entire time, too, and doesn't let up even after your orgasm passes.

You have to sit up and physically pull her off of your tender cock to get her to stop, and when you do she just stares at you with the most frenzied, loving eyes. She throws her arms around your neck and starts crying against your shoulder as she strokes your hair.

"What the hell, mom?" you feel yourself blush as you look around at the women sitting around the table and watching this sudden display of affection.

"I just love you so much," she sobs. "You're my baby, and I love you, and I want you to live the absolute best life you can."

"I love you too, mom," you sigh, tears welling up in your own eyes. "You are the absolute best mom a guy with my condition could ask for! You're so sexy, and you're willing to do whatever I need you to do, and you've given me two of the best fucking blowjobs I've had all day!"

There's another quiet awww from the audience over that, especially once Caitlin jump in and joins the naked family group hug.

"And I can't believe you set up something this crazy just for me! Celebrating my birthday with a house full of beautiful women is the absolute best present I could have asked for, and it's even better knowing that you two organized the whole thing just for me!"

Your mom and your sister each kiss one of your cheeks, leaving little white milk spots. You wipe them off, using the gesture to hide that you're also wiping the tears from your eyes, then turn back to Sierra.

"That was fucking awesome!" you beam, climbing down from the table and reaching under the table to wrap your hand around the one she's using to rub her own clit. "You've definitely earned an orgasm."

You kiss Sierra's neck and massage her breasts with your free hand while you play with her pussy. You let her keep up her pace on the clit and start fingering her at the same time.

"I think I'm gonna need you to start babysitting me again soon," you whisper as you nibble her ear. "You can help release my pressure whenever I need it, and I can help release yours..."

In demonstration, you take your fingers out of her cunt and squeeze both of her tits as hard as you can. Milk squirts out of her nipples, spraying out across the hardwood table in a rain of white droplets.

This rough stimulation is all Sierra needs to go over the edge, and she screams out in pleasure as she cums hard right there in the dining room. She reaches back and clings to your neck as her entire body quakes, pulling you around to shove her tongue into your mouth. It's not a kiss, exactly -- she's really just licking up any residual milk that's coating your cheeks and gums. This woman is exactly your kind of freak.

"My number's on my panties," she reminds you when she finally comes down from her sexual high. "Just give me a call whenever you're feeling horny, or hungry."

"I absolutely will," you promise, before collecting your fluffers and walking away.
