He wants to fuck you with a bigger dick

"I'd love to fuck you right now, but could you make my penis bigger?" He says. "Sure" you say, not really knowing if it would work so you transform back into your goo form, you try to seperate your goo a bit and suddenly there were two puddles of goo and you had two views. You possess his penis with one of this puddles and tried to morph Jim's penis. And like normal transforming his dick transformed slowly into the dick of your original body. It was your luck that you could transform things you possessed too. You left your goo in his dick for now.

You transform the other puddle into a new copy of Krystal, one that hasn't orgasmed a couple of minutes ago. You now were wearing one of Krystal's night dresses and black panties, matching to the dress.

You put away his Shirt an go down his body with your fingers, making his new dick hard again.

He puts up your dress a bit to see your black panties and puts it down a bit to see your breasts. He begins to grab your boobs, his first boobs ever after all. He begins to massage them and you let out a couple of quite moans. You then put away your panties and place yourself on him and put his dick right under your vagina. You hear him say "Yes Krystal, take my virginity." Taking this naughty boys first time made it only better for you. You begin to put his dick into your pussy and go down until it's completly inside of you.

You start to go up and down and her Jim shout in pleasure "OMG, Krystal's pussy feels so good. Having sex feels so good. This dick feels so good."

You increase your speed with every time you go up and down and soon your at maximum speed, going up and down your original cock. After some time you both cum at the same time.
