Cute newcomer Penelope Snaps seduced her stepbro

My First: Penelope Snap’s, the Voyeur Virgin

Movie description: Dear diary, you won't believe what just happened. Mom and Dad left for a trip, so my stepsis and I were supposed to be all alone in the house. Yet, she took the first opportunity she got to sneak her boyfriend in. They've been having sex nonstop, and I can hear them from my room! Two nights ago, I decided I was sick of it, so I went to confront them, but when I saw with my own eyes what he was doing to make her moan so loud, I wanted that too. He was riding her like a cowboy, sliding his big, fat cock inside her pussy over and over. Each time harder and deeper than the last. I couldn't help touching myself as I kept watching them fuck. Penelope and I even had an orgasm at the same time, but I still needed something else inside me, something bigger than my fingers. Then, I heard footsteps approaching my room. It was her boyfriend. He saw me spying on them, and he thought that was hot. Before I could ask him what he wanted, he made me lie on my bed and ripped my panties. He was about to pop my cherry and show me why my sis moans so much, and I was wet and ready.
