Cum hungry slut ♥

This is great

god this shit was so peak

All hail Jaydot and SisterNakadashi

I'm not sure if I want a little tight petite sister to both abuse and love and taste or a fucking big breasted whore sis that knows exactly how to make a man feel good

@SisterNakadashi Bro's a fucking real incest enjoyee

Holyyyy peak

Yo this would be good if it wasn't incest and there faces didn't look so weird

@SisterNakadashi That's not the point of that part. They are still siblings, but their relationship changed. The whole argument in the plot is that they are siblings, and how the FMC reacts to the change of their relationship. In fact, i would say that line was pretty fire. The FMC was confused/insecure during the entire plot until that point. She realized what was happening under the heat of the situation and manifested her toughts that way. The little brother that always needed her help is now pounding her. So no, sibling's shouldn't have sex because they are sibling's what the hell is wrong with you?

Why tf did he turn black he was fucking white at the start

They got along really well I'm not kidding at the end i expected them to get married

I don't really like the art style but the everything else is goated. You can't make them have sex for 30 days and she didn't get pregnant!

thank you Sir JayDot

@SisterNakadashi spitting the truth

OUU SHII🔥😭🔥🔥

Based and Habsburg-pilled. 10/10 nut.

Made me buss

SisterNakadashi spitting, they should like each because they're siblings, not in spite of it!! still, it was a great doujin, both wholesome and sexy... also this is prolly just recency bias + similar sister design (and im not tryna accuse the artist or anything), but this felt almost inspired by /g/635266, there were a few similarities i kept noticing, the cover is almost the exact same pose flipped, some scenes were quite similar like the ice cream -> blowjob scenario, groping while sleeping, FMC perspective etc; regardless, lots of unique scenes and super hot 🔥

I love incest tbh

@SisterNakadashi Based af, I agree

That's it !! 30 days is a looooong time to make a baby 💦👶 Btw thanks for @Jaydot i love you so much

@SisterNakadashi dangerously based beyond belief

Okay so the first night is never usually that bad in any of games so I'll play through-

Holy shit 🔥

"My little brother no longer regards me as his big sister" "I'm no longer his big sister" You do not understand how much I hate this shit, it's the worst trope in incest hentai. Pray tell, retarded fucking gook author, what exactly is the point of writing a sisterfucking story if the fact they are siblings ultimately doesn't matter? If they are effectively unrelated people starring in a generic hentai plot, what is the fucking point of writing them as siblings? Siblings should be having sex BECAUSE they are siblings. Incest isn't a fucking obstacle to be compartmentalised, you stupid cunts, IT'S THE ENTIRE POINT. IF YOU DON'T WANT TO WRITE SIBLING LOVE, DON'T MAKE INCEST PORN. FUCK YOU.
