Your ex pants and looks at you. "Still having fun?", you want to reply but all you can do is bray at her, cum still dripping from your new cock still making you shiver with pleasure.
"Genie, this form is too good for him...I wish he becomes my cock!"
The genie laughs "Well your wishes just keep getting better and better. Since he's gonna be an animals part I'll allow it" and he breathes smoke at the two of you. You feel yourself attracted to hir cock again. You can't stop yourself and you start sucking on hir again.
Your ex smiles and enjoys the attention you're giving her and just watches the change happen. You feel like you're body is melting, but you can't take your attention off hir cock. You're shrinking and you don't care, you rub your whole body against hir cock and it starts to merge with hir shaft. Your legs are pulled up and disappear into the base. Your ex moans as your arms disappear and your body has nearly completely merged with her cock. You keep sucking and eventually you notice you can't move at all. Your head disappears into her large bull cock which has become even larger because of you and your vision shifts to the tip of her cock.
Your ex smiles and puts hir hands on you and rubs you all over, eventually cumming, you feel a jet of cum shoot from your former mouth.
"Wasn't that nice...ahh I gotta unload" Shi holds you and before you've recovered from the sensation of cumming you feel piss coming out through your mouth, leaving a foul aftertaste.
"That felt good" your ex stretches and wonders what to do next...
