Parasite penis

Amanda felt the tentacles move around her cunt as they started to form into a penis.

Suddenly Amanda felt it perk up as she somehow felt it getting hard.

“Alright sinful one, if you truly wish to be forgiven by our goddess, then cum out your sin and rejoice as you join us.” She said

Amanda felt her stomach begin to grow with alien cum of sorts.

She tired to resist the urge to cum until....

1.) She begs for them to help her cum

2.) Shes punished for not being able to cum

3.) They help her cum.
