My summer of sexual awakening

It was only a couple of weeks into summer vacation and I was already sleeping away most of the day from boredom. It was almost noon when I got out of bed. I went into the bathroom and ran the brush through my curly auburn hair a couple of times before heading out to the kitchen. I was wearing a little camisole top and a pair of boy shorts, but was pretty sure I was the only one in the house. My mom and step-dad were both at work, my older sister Chloe was off at some church retreat for the week, and I was sure my step-brother Brian was off with his friends somewhere. Brian usually lived with his mother, but always stayed with us for most of the summer. The last couple of years he had almost always been out with his friends all day long, pretty much every day he was here.

I grabbed a bowl of cereal and started to eat, when I heard some noises from the basement family room. Having thought I was home alone, I quietly crept down the stairs to see who was there. I got to the bottom of the stairs, and there on the couch was Brian and his friend Todd. The couch faced away from the stairs, so they could not see me come into the room. As I got closer, I realized they were watching something on tv, and stopped with my eyes wide in shock when I saw what they were watching. There on the screen was a blond woman totally naked, straddling one guy, while another was behind her. I knew a bit about sex, but I had never actually seen anything like this before.

I stood and watched in shock as the man behind her pulled out of her and moved around to her side. He held his cock in front of her face, and she hungrily started sucking on him.
