Quatre bras

As soon as you hit the button on the omnitrix, Ben started to trasform and transformed into Quatre bras.

Immediately your eyes widen with lust.

"What has gotten into you Gwen?" Ben asks.

"Hush, don't talk"

You pull down Quatre bras pants, revealing his massive cock witch slaps in your face.

"Fuck yes, just like i immagined"

You get on your knees is front of him and start to stroke his massive cock, slowly getting it hard. You start to lick it and stroke it faster until it is completely erect.

You stand up and look Quatre bras straight in the eyes with lust.

"I want you to fuck my ass"

"But Gwen...." Ben says

"No but's. I don't care what you are going to say"

"But you're my cousin" Ben tries

"So? Don't you dare trying to convince me that you have never taught about fucking my ass like there was no tomorrow!"

"Well.... that's true" Ben said a bit ashamed

"Now you get your chance so do it!" With the last word you turn around, showimg Ben your firm bubble butt.

That does it for Ben and he picks you up with ease, holding you above his massive cock.
