It seems that "Pretty Face" is not yet added to the list of taggable parody works.

Parody: Pretty Face

This is a large full color set featuring the transformed feminized Randoh being trained by Doctor Manabe.

Why does he start fingering instead of faping

Base +8, chaos-x -18

Pretty Face hentai is Pretty Rare.
And it's not actually futanari (chicks with dicks), since Randoh is a male with extreme reconstructive surgery after a bus crash (new face plus breasts).

Semi-hard to categorize. There's only one route but it comes with options that don't really branch out into anything, being more like how you want the protag's "experience" to run its course (adding toys, drinking or getting semen on your face and so on). You could very well categorize this as game CG if you wanted to.

Actually it's To love-Ru.
