Sex With Me Is Better

I’ve had sex with my good friend’s boyfriend Nathan so many times and she has no idea. It all started about a year ago after a night out when I was crashing at her place. She was drunk and went to bed, leaving us alone together. He made the first move but I didn’t resist. We ended up f***ing on the sofa and he stuffed my mouth with my thong to stop me moaning and waking her. We felt guilty after, but less than a week later, it happened again. This time at my place, where we could make as much noise as we wanted. And he’s been cheating on her with me ever since. He says he loves my friend but that the sex with me is better. I feel bad, but I also love that he wants me enough to risk everything. It’s so hot whenever we’re together.
