As you were having fun with the dildo in your body, you feel yourself beginning to change. First your eyes begin to turn black, while the iris's, and pupils fade into them, and a second pair of eyes grows about them. After that, your breasts grow two cup sizes bigger, causing your bra to break in half.
You then feel something grow inside the skin of your legs, as you were going at it with the dildo, which was glowing under your pussy. Finally, as your thighs, knees, and ankles begin to swell, the skin on then rips, revealing four long purple tentacles on each leg. Your new tentacle legs grow even more, and two of them rip your jacket in half, from behind. You finally cum through your pussy, after growing big enough, that the top of your boat rips apart, and you leave through it.
Skin was also removed from your bottom skin, as you take out the dildo that transforms you. You decide to share the dildo with other people who would come towards your waters.
