[MF] Still live with my ex and I fucked her friend.

This is my first time submitting, be kind! :P

Me and my ex broke up 3 months into a year long lease.  We had been together for 10 years before that,  so we decided that instead of wasting the money breaking the lease we could be civil and live with each other for a few months.  Needless to say,  it was a tough living situation,  but it had its benefits…

Shortly after we broke up she started meeting new friends and going out all the time.  She would bring them by the house before they went out for the night and occasionally one or two would spend the night. One night I had fallen asleep early and didn’t realize her friend Amanda was sleeping over. I had always thought Amanda was sexy. Blonde, 5’2″, just the right amount of curves on her tight little body,  blue eyes and little rosebud lips.  When she slept over she liked to tease me, she would change into these tight little sweatpants and she would always leave her panties she had been dancing (and soaking) in all night in my bathroom (the only bathroom in the house,  coincidentally right next to my bedroom door). I would come home from the bar and find her skirt and black panties covered in cream on the bathroom floor. The only thing I could do was pick them up and see what her pussy smelled like. I would take out my dick and rub her pussy wetness all over the head of my cock, and use it to jerk myself off. I’d shoot my entire load into her panties and leave it for her to find the next day.  She always smiled at me when she left and she never told my ex, so I felt like it was our dirty little secret. I had a lot of fantasies about fucking Amanda.
