"I'll do anything!" she pleads, grabbing my hands. "I'll do anything. Just let him go. He made a mistake." "That's not an excuse. It was a costly mistake." "Please. I'll do anything you want. Anything at all." I let the silence hang in the air between us as I think carefully, my eyes drawn to how firm and full her tits are. "Anything, princess?" She lets go of my hands and straightens, raising her chin. I watch as she swallows nervously. "Y-Yes. Anything at all." I raise my fingers to her face, smearing my thumbs with her tears.

We stood across from each other, with a bed in the middle. The bed was surrounded with golden pots of burning incense, the fragrance intoxicating. On one side of the bed stood a warrior wolf from my pack, and on the other side was a vampire from Diego's pride, both present to guard us. Chairs were set in both sides of the large room, with the werewolves occupying the right side and the vampires on the other side. Everyone stood when the head witches of the three covens arrived and took their seats adjacent to the two parties. " Creatures of the underworld, we have all gathered here to witness something spectacular, something unheard of, the mating of a vampire and a werewolf. These two from both sides have claimed to be mated to each other even though they are not of the same kind, so tonight, underneath the full moon, we shall witness them in bed to attest if the Moon Goddess truly destined them for each other. Let the drums roll!", one of the witches addressed everyone. The incense had aroused us . My were hard and erect, and I could clearly see the bulge in Diego's pants as he stood across. The drums signalled us to begin the mating process, and we got onto the bed. We gently , suppressing the urge to tear each other's clothes off. I felt a bit insecure and ashamed. I could literally feel my alpha's eyes on me and could only imagine the disdain that will be written on his face. Diego's father too was watching, together with their maester. Everyone we knew was there to watch us have and I just couldn't bring myself to feel comfortable. Most importantly, I couldn't help but wonder, what if we die mating?

Whispers in the underworld mentioned that Jason Marino, heir to the Family with its hands in the cross-continental arms trade, supposedly loved women with slim waists. Since his recent return to the country, his eyes had landed on Sonia Stewart—sworn sister to my fiancé, Andy Black. When Andy found out, he disappeared for three whole days. I finally tracked him down in the Family's club, only to overhear a conversation that shattered my world. "I'm not just going to stand by and watch Sonia marry that playboy Jason," Andy was telling his lieutenant. "On the wedding day, you need to swap Sonia's wedding car with Leona's. No one must find out!" His lieutenant thumped his chest, swearing, "No problem, boss! I'll get it done. But... What about your fiancee, Leona?" Andy let out a confident laugh, as if he were in control of everything. "I'm the Don's hand-picked Consigliere. Jason knows Leona belongs to me, so he won't lay a finger on her. Once I've slept with Sonia, he'll have to give up on her. After that, we'll just send someone to pick Leona up. She won't suspect a thing. Instead, she'll be scared and trembling… Pathetic but adorable nonetheless. She'll come running right back to my arms!" Every word was like a bullet leaving holes in my heart, every tone tearing it apart. I stumbled away as fast as I could, praying they wouldn't hear the sound of my heart breaking. When Andy tried to pick me up according to his plan later on, he broke down.

I've been married to the prince of the underworld for ten years and have endured countless life-or-death situations by his side. My hands, once trained to play the piano, are covered in calluses from holding guns and stained with blood. But at 28, my husband ends up falling for a young woman from the slums. She's as delicate and pure as a chamomile. She's his well-kept little secret—until I run into them at the woman's prenatal appointment one day. I storm up to him, demanding an explanation, only for him to nonchalantly hand me divorce papers. "Sonia is a devout follower of the church and can't have a child before marriage. I must make an honest woman out of her. Sign these, and you'll get 40% of the company's shares." I refuse to do as told, so he corners me. In the end, he has my crippled younger brother tied up and forced under a hydraulic compression machine. "Sign the papers, Maeve, or watch your brother become a human mince pie. The choice is yours." I fall on my knees and beg him to stop. As the machine turns on, my hands fly to my aching lower belly, and I scream as I lose consciousness. When I wake up again, I'm back in the hospital, in the same spot where I ran into my husband and his mistress at her prenatal appointment. This time, I don't confront him. Overnight, I make arrangements with a sanatorium abroad, get divorced, and run away from home. Yet the moment I truly disappear, my husband loses his mind.
