You are paralized

This can’t be real. You must be dreaming, or hallucinating. You simply cannot wrap your mind around it.
While you stare at the pair in disbelief, Xallia pushes Carly on the table and spreads the woman’s legs. She takes her large purple cock and pokes it against Carly’s clitoris. Xallia’s magnificent shaft pokes what used to be Carly’s dick, proudly showing which is the biggest and which is but a shadow of what it used to be.
After that, Xallia slides her dick to Carly’s wet entrance.
She says “Let me show you how much better it is as a woman.”
She then sheaths daemonic cock inside Carly’s human pussy. Carly moans in a high pitches voice as she her pussy accepts its first cock ever.

You watch with your mouth agape as Carly gets fucked by the succubus. She moans and groans as her young pussy gets violated. Her hands reach for Xallia’s head and caress her horns.
“Your horns are so beautiful.” Carly compliments her lover.
You realise Xallia must have shown Carly her true self. How long did Carly know the true nature of her assailant?
“Thank you my sweet.” Xallia replies. “Your breasts are beautiful too. Much better than your ugly masculine chest.”
Almost on command, Carly put her hands on her breasts and squeezes them.
“Mmmh, yes. And more sensitive. Thank you for turning me into a woman.”
You can’t believe what you are hearing. Carly is actually happy for having his masculinity taken away?

“What about down here?” Xallia says while pressing her thumb on Carly’s clit.
“Ahhh.” Carly groans. “Much better then what I had before. Mmmh, yess. Play some more with it, my love.”
Xallia mercilessly toys with Carly’s clit, punishing it for having been a dick for such a long time.
Soon Xallia starts rotating her hips as she fucks the poor woman. Her dick churns inside Carly’s tunnel and pulls more moans from the former man.
You feel your pussy has become incredibly wet just by watching this. You quickly place your hand on it, hoping it would contain the lust, but it seems to have the opposite effect.

“You know, Carly. This transformation is only temporary.” Xallia mentions.
“Noo,” Carly moans. “I want to stay like this, be a woman for the rest of my life.”
“There is a way.” Xallia says and lower her head to Carly’s ear. “All you have to do is let me cum inside.”
Carly instantly wraps her legs around the succubus and yells. “Yes, cum in me. Lock me in this form forever. I want to feel you shoot it deep inside me.”

You’ve had enough, you can’t handle this anymore.
You leave your place by the door and sneak your way back to the stairs. As you are halfway the steps, you hear Xallia moan and realize Carly’s fate is sealed.
You hurry into the room you chose earlier, jump in the bed and hide underneath the blankets. You try your best to sleep, but your dreams are haunted by Xallia. You see her with Carly by her side, the human’s belly swollen with her spawn. The dream evolves and next you see your best friend from childhood nurse from Xallia’s breasts. He too transforms into a girl.
When Xallia mounts your old friend, you see her renounce her masculinity, like Carly did before. Then Xallia orgasms and your friends belly quickly grows.

You experience more such nightmares and have a very restless night.
