One day passed since the little vixen fixed the foreskin-crushing-nightmare ring upon his brother's penis.
The fox feels pain and can't really enjoy the day without the feeling that something odd is happening right now to his foreskin.
He blushes and moves his arms. "Oh what is happening here?"
Vixen while touching his shoulders: "Hehe see it will look even fancier after the ugly foreskin has fallen off."
She escorts his brother to his room and walks off.

The fox can't wrap his mind about how hot his sister has been earlier as she was checking his private parts out. He sneaked a few peaks into her crotch aaaand he's rock hard.
A pity that he still has this Circumcision ring tightly applied around his foreskin. He just can't masturbate properly like that. The fox falls asleep after a few more mumblings, why this has to happen to him.

The next day begins and sis enters the room.
Vixen: "Ohh Foxy! Your foreskin went all black, I bet we can remove it already!"
She makes some tactic movements with her paw on the ring and unties the screw, which keeps the black foreskin in place.
*Chirrp*
Fox: "This kind of hurt a bit..."

The clean glans poked out of the ring and the destroyed foreskin is thrown away.
Vixen: "Did I promise you too much? Your wiener looks so healthy and quite a bit erect now. " ^__^
"Now wait until it heals and we can have some fun."
Fox: "Fun?1 Oh please let me sleep with you!" x3
