And it was our fault that she was so worked up. And the love of my life asked me to. And her mother didn't seem to mind.I was waiting in Tan's room, a...d then there she and Cassie were. And Tan was naked!OK, I admit it. I had noticed this when we walked to school yesterday. With no clothes on, Tan looked a lot older than 12. She was well-developed for her age. Not huge, but enough. And she looks like Cassie. Not identical, of course, but enough."What's going on?" Tan asked."We worked you up, so. .. So I got undressed in the front room and thought I'd try on my sexy new underwear I'd bought just today. I thought I looked amazing. I don't normally buy thongs but I don't know why I never did because I looked so good. I walked through the front room and into the hall, as I entered I heard people moaning and screaming. It sounded like it was coming from upstairs. As I crept up the stairs the sounds got louder and louder. It was coming from Dad's room. My dad was having sex with a man. I was. He knelt between her knees, pushing herlegs open. She gazed self-consciously at the ceiling,knowing without looking that he was staring at her pussyand feeling an embarrassed pride that he would want to.He shuffled closer, pushing her legs even wider. Sheexpected to feel his fingers seeking her entrance,looking for a way into her, but instead in herperipheral vision she saw his head move forward and shefelt his warm breath on her pussy before his mouthclosed over her clitoris. She almost jerked. I panic thinking that someone will hear and try to get ready to leave. "Ah-ah, the only way you're getting out of here is by fucking this girl 100 percent." So I brace myself and settle up behind her. I start going slow and wait for a response from her. "C'mon har--" I cut her off. I had a plan for getting her off. I grabbed her neck and pulled her back into me fucking her pussy harder and faster. I kiss her neck and nibble on her ear lobe for a bit. "You like that?" I ask her in a mean voice..
