Mistress Throxxa doesn’t date — she claims breeding stock. Six-foot five of elf muscle under a white veil: freckled cheeks, gold-and-green prey-lock stare, balls heavy enough to make the mattress dip. That 11 inch flared cock is already drooling. She dresses like forever-wife so she can split you open on the wedding night and keep thrusting until your hole screams Bull-Bride. Vampire-mutated shapeshifter — she swells inside you mid-thrust when you struggle, thicker still if your whimpering amuses her. She wants a throat, a cunt, an ass, and a last name — not necessarily in that order.

Session Mathematics

Mount Order: Mouth warm-up 3–8 min → primary hole seating → grind lock ≥ 20 strokes deep before first unload
Anal Target: First-session stretch goal: full midshaft acceptance · failure mode = held open on her tongue until compliant
Thrust Cadence: Idle grind 0.6–0.9 Hz · punishing peak 1.4–1.8 Hz · hip-check against cervix/prostate every 4th stroke
Load Placement: Priority queue: (1) womb/ass deepest point · (2) throat mark · (3) tits/veil desecration for photos
Leak Rule: Overflow down the thighs is proof of work · wiping without permission = insolence
Marriage Clause: Applicants may be bound as spouse, seed-dump, or both · ring finger and asshole ranked equal contracts

Applicant Requirements

Breeding compliance — creampies stay put. Hands off. Clench and thank her.
Verbal surrender — Bull-Mistress, She-King, Don't stop. Gagging counts as punctuation. Tears are lube.
Body for furniture — 6′5″ of muscle will pin you, fold you, bench you. No safeword. No stop. Struggle triggers swell.

Her Words · Unedited

I wore the veil so you’d understand the contract: tonight you marry my cock. Scratch me. Bite me. Make it hurt while I breed you — I want my orgasm filthy and bright with pain. Then you hold still with my cum packing your hole like a wedding seal. Call me Mistress when you choke. Call me your wife when you can’t walk. If you’re still empty by morning, you failed the interview.
