I was home this weekend, and my sister and her boyfriend were hanging out. We were watching a movie, until my sister went upstairs. Her boyfriend followed soon after. Then about 30to min later, I heard bed creaking noises so I went upstairs. I listened at her door, and I heard her moaning. And I gotta tell you, I was horny as fuck. She had the best sex moan I have ever heard, and my cock was hard as fuck. Unfortunately for me, they were pretty much done and started getting dressed again. So, I ran to my room and stroked like there was no tomorrow.
So, im wondering, is it weird to enjoy hearing your sister have sex? I am not sexually attracted to my sister at all, so im wondering how this happened.
