Such a cute futa fucking her sister! Great x-ray view on p. 18, I like that a lot! Thanks for sharing this one with us

is it contagious or is it that they both are futa but when not in the mood it is hidden?

@dinosayr : from what I can read, the younger sister grows a penis when she is horny and the older sister helps with it (but masturbates afterwards). After the two have sex in the final scene, the older sister suddenly grows a penis

pg25: panel 1: What is!? This is!!
panel 2: No Way...!? Why
panel 3: Why, on my genitals----

Leads me to believe that she wasn't a futa before and that it's contagious.

My Japanese isn't great, so that's all your getting. If anyone that's good at Japaneses can verify, that be great.

I really like the futa action but I wish it wasn't a love live doujinshi
