Yeah I actually bought that one.
I've got a request.
There's a fairly short doujin that goes like this:
>Alien frogs make pills to give themselves huge cocks because that's apparently what humans want
>a girl and a milf take one each and grow huge cocks
>girl finds boy jacking off to a lewd pic.
>Stuffs her cock in his mouth
>futa milf then takes his ass. There's an amazing page for the spitroast that ensues that shows those huge cocks in him
I can't fucking find it, no matter how hard I look.
