To be honest, stitching a cock and balls onto herself and making sure they worked properly is something I can see Fran doing. Though it'd be more likely she would knock Veronica out and put them on her.
It is SO rare to really see good Franken Fran futanari. The only other good Franken Futa I recall seeing is an OLD doujin about 10 years old at least. Huh... I never realized they started a revival last year. Shame Pixiv still has so little porn of it... Then again, it is a pretty twisted series. Nonetheless, this is a VERY welcome little set! Thanks SO much, megaericzero, thanks SO much!
