My cold husband from an arranged marriage uses me as masturbation material every night while I pretend to be asleep

https://www.cmoa.jp/title/330630/ Born into a poor noble family, I, Amelia Windisch, was always compared to my sociable and lovable younger sister. The one who said he wanted to take me as his wife, on the condition that he would take over my family's debt repayment, was Lord Darren Austin. But immediately after registering our marriage, the words that came out of his mouth were a rejection: "I have no intention of getting close to you." …So he doesn't plan to love me. That's what I thought, but… why…? While lovingly calling my name as I lie (pretending to be) asleep… he's checking my breathing! My scent! And… m… masturbating to me…!?
