My sister (F23) and I (M22) had sex yesterday

I'd love to elaborate, but I don't really know where to start or stop. <br>- For context, things like this have rarely happened in my life<br>- Both of us have never been attracted to each other. My sister is very pretty, but she never seemed lust-worthy. We get along well, but I didn't look at her like that. <br>- I'm not exactly a virgin, but it's not like I get lots of action. <br>- Same with my sister, who has been in a relationship with someone for years but has never been very sexually active. <br>- She was home for two weeks and she has to go back. <br>- We've both been extremely horny the last few days<br>- We were both lonely, so we got to talking and then we started kissing. A little while later we went to my room and had sex. <br>- It was nice and I was relieved that I could please her. It's been ages since I've had sex. <br>- I know it's wrong and I can't tell anyone else. I also posted this because I'm not sure what to make of it. <br><br>I know this sub isn't active much, but I didn't know who else to turn to. Advice would be appreciated, but please don't judge.
