Serene is delighted that her experiment worked, and Leana eagerly strokes her new cock until it becomes big and hard. After that, the two futanari beauties celebrate Leana's transformation by having incredible sex. Behold, the power of science!

Kimmy is eager to please, and agrees to it.Serene says that the first product to try is lingerie. She surprises Kimmy by rapidly stripping Kimmy out of her clothes and getting her into the sexy lingerie. Serene then maneuvers Kimmy into various positions, to test the comfort of the lingerie.Kimmy then gets surprised again when her lingerie is quickly stripped off, and Serene tests various massage oils on different parts of Kimmy's body.Next, Serene uses a vibrator and a dildo on Kimmy, to test which one she likes better. After getting Kimmy's feedback on those two items, Serene says the last thing to test is a strap-on. She admits that she's the most concerned about the quality of this item, so it would be better to test it under 'real world circumstances'. In other words, they should simulate realistic sex. Serene asks if that's okay. Kimmy is still in disbelief that all this is happening, however she's also turned on, and agrees to it!
