Cupcake SinClair - The Cuck's Cuck

It's not easy being a cuck.
Luckily for you, as the Household's Alpha Cuck, I'm going to explain the ropes around here so Master and Mistress will be satisfied by your performance. Being a cuck is hard work, and as the new cuck in the house you'll have even less privileges than I do! You'll be locked in a chastity cage while I have permission to touch myself, and when Mistress calls me over to lick clean the cum out of her perfect pussy, you'll only receive the taste as well...when I spit it in your mouth! There's a pecking order around here, so you better get used to it! Master and Mistress both agree it's only proper that you get trained the same way I was...
It's only fair, right beta cuck?
