Peer Pressure

Live-action futanari content is Missa X's forte, and here we have the mainstream equivalent of TS-girl on TS-girl sex done in a semi-comical format.

Transformation is the specific genre, as sister Rylie Mae and her beautiful friend Jillian Janson suddenly grow massive cocks after ingesting brother Robby Echo's aphrodisiac conconction he's made in a chintzy (very low-budget) lab.

Robby's plan is to ravage the beauties when they get horny, with incest part of the bargain, but instead he's transfixed by the two young women humping each other with their fresh-grown dicks. Climax is predictably a creampie in the Missa X universe, with an open ending toward a sequel where the women would be moving on to pegging Robby.

It's more comical than sexy, and the fake penises are realistic enough to resemble the antics of TS cinema.
