I Am In Love With My Sister’s Daughter

So I am 25 and my niece just turned 20 (my sister is much older than me).

Since she was a teenager, I know that she had a crush on me. She would always find a way to cuddle up to me, hug me, kiss on the cheek.

All sounds innocent until a night about 2 years ago when she showed up at my place, drunk and scared to face her mom in that condition. I lay her down on the couch and as I did she wrapped her arms around me and went to kiss me, tongue first.

I pushed away - at that point not interested. But after a shower she went home the next day, leaving her panties in my laundry basket. I didn’t know what to do so I kept them. Never washed them though.

I don’t know what the urge was but something about having them just turned me on even though I didn’t have any attraction to her. It was that week that she came by again and apologized for making a move, asking me not to tell her mom.

I gave her a hug and before we knew it, our lips were locked. I pulled away but she pulled me back. It didn’t go further than some making out and a feeling each other up but I was wild for her suddenly.

I only knew her as a kid but I could now see that she’s an adult. It became a regular thing any time she came my way to drop by my apartment and have a bit of fun.

Things really got serious when one day, she told me she loved me. We said it all the time “I love you” “love you too” but this time it was different. She looked deep in my eyes and said it, with the kind of love that only comes from romance. I worked up the courage to return the romantic “I love you” shortly after.

And now we basically function the way a committed boyfriend and girlfriend do. Except it’s all limited to my apartment really. We don’t know how far it can go, obviously it can never come out to family or friends but our hearts are really in it.

I just don’t know what to do. But I know I’m crazy about her
