what to do when your favourite doujinshi has no tentacle impregnation ?
make one yourself of course
mad men really did it

So love the use of the tentacles wrapping around her waist to secure itself to her pussy, to ensure a proper seal to prevent leakage of cum.

This is absolutely top tier. Is there any name for the fertilization of eggs still in the ovaries?

Do a Parody tag search reveals Mahou Shoujo is practically its own industry

Is there any other doujinshi described forming the embryo like this?

I this really an ongoing series?

Base +8, 9Third +6, kaerFlanA +6

@LUIGI-DUDE yes, there's more pages on the artist's twitter (and still ongoing but the artist works on it intermittently with other projects), but they haven't been translated

I'm looking for more of the "corrupt all your ovum" stuff, anyone got any recommendations?

Base +6

Tentacle Netorare with impregnation and Fertilization Biology Lessons is god-tier genius.

Hentai with educational value is an unserved niche.

To those of yall looking for ovary destruction, Akiyoshitaka has a ton of stuff focusing on that exact fetish: https://e-hentai.org/g/2699847/1f5034d7c9/

The plot thickens... just like Misa's body is going to as that baby develops.

@nhami

I can't find anything by that title. I simply searched for "Fertilization Biology Lessons", but no hits, at least here.

Base +6, testingtesting223 +6

YOU ARE MY SPECIAL

Taking impregnation fetish this far is... a really creative decision. I applaud it.

Base +6, PlutoPowa +6, kaerFlanA +6, pmail8281 +6, 2Forward1 +6, sasukenii +12

thanks.

Are there more pages? A Sequel or prequel?

Base +6, DooMer13 +7, sasukenii +12

Unfortunately, it seems like the end :(
