Warning: Dark and BDSM theme story which involves highly adult content in the beginning.

What if she one day came across them? Who would hire her to serve as his personal maid? Who would control her body? Whose heart would she rule? Who would she fall in love with? Who would she despise? *** “Please don’t punish me. I’ll be on time next time. It is just that-“ “If next time you speak without my permission, I’ll shut you up with my shaft.” My eyes enlarge, listening to his words. *** “You belong to me, Kitten.” He pounds into me hard and fast, going deeper into me with his every thrust. “I… be…long.. to you, Master…” I’m just moaning insanely, clenching my hands behind my back.

Julian Cross has always been a good person. Soft-spoken and loyal, he’s the kind of person people trust… and use. He’s also been in love with his best friend for as long as he can remember.

A man who doesn’t feel, doesn’t care, and doesn’t let anyone get close enough to matter. It should have been simple. A game. A plan. A means to an end. But nothing about Nikolai is simple. Not the way he looks at Julian like he already owns him. Not the way his touch burns, leaving behind something darker than desire. Not the way Julian starts to crave him… even when he knows he shouldn’t. Even when he knows it can cost him everything. Because Nikolai isn’t just a man. He’s control wrapped in violence. Obsession disguised as restraint. And once he decides something belongs to him… he doesn’t let it go. What started as a game… ends as an obsession. Now Julian is caught between loyalty and temptation, truth and deception, control and chaos. And the deeper he falls into Nikolai’s world, the harder it becomes to remember— Was he ever the one playing the game? Or was he the target all along?
