Passing my mom and dads open bedroom window (We lived in a ground floor apartment. We've moved since) when I was fifteen years old, I saw and heard my mom with two guys. My dad was driving his truck I don't know where, but I knew he'd be gone at least another two days, so did my mom.
She was naked, as were the guys and both were fucking my mom. She was sat on one guys cock, whilst the other young man was fucking her asshole from behind. And both men were not much older than I am now, probably around eighteen.
I didn't let them know I was there and I didn't try to get a better view. I didn't need to as they were only maybe ten feet from where I stood. The big muscular guy who was fucking my moms asshole sheilded me from anyone seeing me, so I just stood there totally shocked.
Before I came to my senses and moved away, I distinctly heard my mom telling the guys to fuck her until she orgasmed again. Her voice brought me back and I walked around the block to a freinds house completely freaked out.
It happened two years ago. Yes I'm seventeen. And I've never said a thing. Not because I don't love my dad, I do love him so much. It's because I know just how much he loves my mom and how much it would hurt him. The thing is, it's making me feel real bad knowing my mom has cheated on him, and I know it.
I've never seen the two guys again and as far as I know, she hasn't done anything like it since. But then I'm not always at home.
I'm now wondering if I should tell my dad, or at least let my mom know I saw her that day getting fucked by young men, not much older than I am now.
