/d/'s thoughts on nipple penetration?

>>11301449 (OP)
I love drawing it

It's the best. I wish there was more in the diffusion threads.

>>11301449 (OP)
bizarre, but then again, that's what /d/ is for
not my fetish is all

>>11301449 (OP)
Can it be done? Any medical students wanna answer this?

>>11301449 (OP)
I hate it. Because i love big nipples, but it always pared with this tag. Totally ruins it for me.

>>11301512
Sponson, that you?

>>11301449 (OP)
It's one of my favorites, I wish there were more. I have read everything on nhentai with the tag

Not enough content featuring it.

Absolutely impossible. The nipple is not actually an orifice. Milk comes out through pores in the skin so unless you can fit your dick in one of those this is something that will only happen in hentai.
Not a medical student.

Love it, can’t get enough

>>11304680
This is fantastic

I don't like it when it's done with dicks. But if it's sextoys, tentacles or nipples i'M rock fucking hard.
Sometimes i have a dream of a lactation and breast expansion virus that only infects others through infected milk hitting their mammary glands. So nipple to nipple or syringe action needed.

>>11301449 (OP)
Doesn’t do much for me. (I’d probably prefer the nipple penetrating desu)

>>11301449 (OP)
There's not enough of it.

Also needs more of its variants like mammary glands inflation (by milk or cum) or breast pregnancy.

Maybe invent new creative variants of it.

No. Milk comes from a series of glands and comes out of pores. A woman would need to be genetically modified to grow an orifice that could contain a cock there.

Also another fun fact, breast size has nothing to do with milk production. Gland depth does not directly relate to breast size

A lot of stuff in hentai is straight up impossible when applied to real life. Like all of those hentais where you see a woman swallowing gallons of cum would probably destroy someone's innards in reality. Not a medical student either.

>>11311231
Well, there's "impossible" and there's "impossible", right? Milk ducts and milk glands exist IRL. It'd be really weird and unlikely that something could evolve to make alternate use of them, but they are there in ways that a nipple pussy capable of handling a human cock just isn't.

What the fuck is with you faggots and maggots?

>>11311653
Nematodes. It's absolutely not implausible that some kind of nematode could evolve for that.

>>11312642
Where do you think we are?

>>11301449 (OP)
Tubes inserted into nipples for breast inflation is so rare most new art is AI.

A lot of of what I've got is super old because there just isn't very much of what I consider good content.

The world would be a better place if we could impregnate women this way.

Rains Rave (RJ154362), Lilia's Livelihood (RJ189029) and NurseryDimension (RJ294242) all include nipple fucking, breasts pregnancy and nipple birthing.

(be warned picrel is from guro set)

Hot
Imagine if you could rape and impregate girls like that

>>11301449 (OP)
I wish there are body modification scenarios where women either:
>Pettankos secretly host parasites on their boobs so they become more attractive. This practice secretly become widespread amongst nobleladies and ambitious harem ladies.
>To achieve nipple penetration, a new type of breast implant is invented. In order for the nipple to accept penetration, constant dilation in form of nipple plugs are necessary.

>>11321405
Sauce?

>>11324076
Filename, rest of set came from fanbox (kemono) though. Also you should be using 4chanX as it'll automatically generate pixiv links (when filename is correct).

>>11324309
I'm on mobile, so unless 4chanX gets a mobile app still doesn't help. Just link me to the pixiv or kimono and stop being a wannabe elitist twat. As unless it pops up via reverse image search it basically impossible to find.

Any good nipple plug art?

SYMMETRICAL DOCKING!

There's a lot of weird anatomic impossibilities in hentai that I don't bat an eye at. Idk why this one just takes me out of it. Feels like ot was drawn by someone who has never seen a nipple up close irl.

Nipples don't have a single streatchable hole in the middle. It's pores

>>11328846
Yes. Doing it properly requires lots of smaller tentacles or parasites. Surprisingly little of that exists.

I like seeing the penetration but I don't like seeing them gape.

>>11311653
There is an isopod that evolved to eat fish's tongue and live parasitically in it's place. It is possible.
