"Please, let me have sex with the horseman!" you exclaim as the last glimmers of your old self are extinguished.
"If you insist," Mistress says with a smile. "Horsey, get hard and take this girl from behind."
The horseman's penis becomes erect on command. You hope one day you'll be that obedient to Mistress. The horseman walks over to where you stand on all fours. He kneels behind you and thrusts into you with his powerful hips. It feels even better than you imagined. He thrusts into you again and again. You sit there moaning, passively getting taken. Mistress didn't order you to do anything, after all.
At last, you both orgasm and you feel his sweet seed enter you. His penis starts to go flaccid when Mistress says, "Keep going."
Instantly, his cock becomes erect again and he thrusts with renewed fervor. You don't know how long you sit there getting taken from behind, but you don't care.
When it's finally done, Mistress puts a bell collar on you and tells you that your new name is "Kitty."
"All who slight me end up here, as my pets/toys/slaves," she explains to you. You're so lucky Mistress chose you.
She has you give the horseman a handjob and he cums all over you. You lick yourself clean, then Mistress orders you to take a shower. All five of you go into the shower as you shower you say to Mistress...
