Concept: XXX Files - Episode 3

I felt stalked, watched, and like my privacy had been violated, even in my own house, and I secretly liked it. When my family and I first started getting these letters from a stranger telling us he had been watching us, my husband thought it was a prank. But this person knew our routines, our habits, and even the type of lingerie I wear at home, or the times of the day I let my big tits out. They even knew that my husband loves eating his stepdaughter's pussy, or that I have tempted my stepson into letting me suck his dick dry more times than I can count. The letters claimed our stalker wouldn't stop watching us until we moved out, but we couldn't leave, and we couldn't stop having sex with each other either. We were too horny to go back, so if he was going to watch us fuck, we were going to give him a show he would remember forever, all four of us.
