Merges your dick and Zoe

You see your mom press a button on the calculator and there is flash of light over your sister. When the light fades you see your sister standing there but she looks larger, hotter?

You notice her breasts are bigger, her body is also tighter or looks harder? You cant seem to describe it but she has viens all over her body like a body builder and looks harder?

You are definitely hard, however while you can feel your dick you can't see it anywhere.

You suddenly feel like there are tiny hands touching your dick, while you notice Zoe touching herself.

"Well that wasn't what I was expecting..." mom says to Zoe. "How are you feeling?"

"Great, never thought I would ever be this close to my brother, let alone his dick." Zoe responds.

It then dawns on you that mom merged Zoe with your dick, but that it effected her in a strange way as she is still in her body, albeit it being enhanced she and is connect to you through your dick. You then fantasize about having sex with your mom.

Zoe suddenly shouts "Thats a great idea bro!" As she approaches your mom.

Zoe wastes no time ripping moms clothes off and inserts two of her fingers inside moms pussy. You moan as it feels like you penetrated her pussy with your dick. Next Zoe rubs her breasts against moms which feels like someone is rubbing the head of your dick directly. Zoe then gives mom a deep kiss and shoves her tongue into her mouth deeper than should be possible, resembling more a dick than a tongue.

The mutliple stimulation proves too much for you as you orgasm causing Zoe entire body to convulse as she cums from every orifice, cum flowing out of her covering herself and mom.

You are exhausted from Zoe's dick body cumming and you pass out. You wake up a bit later.
