Is it normal that i want to have an intimate relationship with my niece?
I don't know how to word this, but I feel like I am in love with my niece (sister's daughter). When she was younger, I always noticed how beautiful she looked (the type where you realize that when they grow older they'll be really attractive), but over the years she just became stunningly beautiful and sexy that I started to think of her in a "dirty" manner.
The problem is, I'm married right now to my best friend in the whole world, and it's heartbreaking to have to keep this a secret from her, but it's just so hard to control myself now. We even visited her house over the weekend a couple months ago, and I snuck into her room and started jerking off to her scent. However, she caught me with my dick out, but instead of calling her parents, she just went on me and we ended up fucking the whole night, and holy crap it was fucking amazing I think about it every night.
It's been three months since then, and I don't know how to break it to my wife, but I can't stop thinking about her so what do I do? Right now, she's 18, and I'm 45, and I know it's the age of consent, but I don't want to betray my wife or my sister. What should I do?
