Finally fucked my elder sister

So one day, when my older sister and I were sharing a bed, she thought I was asleep and took my hand and started kneading her breast while still clothed. Since then, she did this almost every night, gradually she started to keep it inside her t-shirt, and soon she started to keep it in her bra too. But as things escalated, she started playing with my dick, fingering me, sucking her boobs, etc. One night we decided to go all out and have sex, we did it all, I tried to insert my dick inside her, but something happened and I decided not to do it...I wish I had, but somehow 6 years passed and it became now (a few days ago), we were alone at home, both of us were dating, we were sitting on the couch, and all my teenage memories started coming back, and...she was so turned on, one thing led to another, and we fucked, we have been having sex almost every night since last week, but last night she was so turned on that she took off the condom and let me cum inside her. And I think I got her pregnant. I don't know if she'll keep it or not, but it's just too hot. I swear to my mom it's true.
