A nice flat one!

As her cock was still rock hard inside of his ass the futa pulled out a nice flat crimson cage as she let out a deep sigh of relief.
"I think that this is going to look just brilliant on you~"
"W-wait a second! T-that's too small, it won't fit right!"
"Oh don't worry about that, if it doesn't fit right at first then I'll just squish it just right until it fits perfectly on you. Trust me slut you will cum to love it." The futa said as her cock throbbed inside of him shooting a few more shots of her pudding thick baby batter inside of Vince's tight ass. Making sure that she had done her best to knock him up with a litter of her kids as she growled into his ear.
"I'm going to give you a choice, either I can put it on you right now or I can put it on you later in front of your family as I sit on your face. Tell me which one would be hotter to you. Ok?" She purred into his ear making his back shiver as his poor abused prostate sent pleasure shockwaves down his spine as he felt like his life was falling apart!
"I don't want to wear that thing at all!"
"In front of your family it is! I'll be sure to tell your mothers that I'll be coming over for dinner~" Miss Khan said as she licked her lips and began to grind her dick into his ass again her cock was still rock hard as he whimpered in pleasure as she spanked his fat ass once making it jump! Vince yelped as she left a nice big red handprint on his ass as she growled in lust.
"I think I'm ready to fuck your ass again slut, are you ready for me to make sure that you become a mother?" She asked placing the chastity cage onto the desk as she licked her lips and began to thrust into Vince again making him groan and moan in pleasure.
