It was Wednesday, and I rushed home, knowing I'd have the house to myself, with only one thing on my mind.

I entered the house, dropped my bag, and kicked off my shoes. As I headed up the stairs, I heard moaning, so I slowed down and crept along the landing.

The moaning was coming from my older sister's bedroom; this was new to me. Someone was home on a Wednesday. It was also the first time I'd heard moaning from a room apart from my parents.

Her bedroom door was open just enough for me to poke my head in. The first thing I noticed was the warm scent of sweat and a sweet smell of something I'd never smelt before.

Then I saw my sister, with her dark mousey brown hair and beautiful, sweet face, with her eyes closed. As I continued working my way down, I saw her gorgeous little tits with hard nipples like cherries on top of a cake.

The more I saw, the harder my cock was getting. I had to see more, so I quickly looked back at her face to check her eyes were still closed. That's when I noticed how flushed her cheeks were and how beautiful her lips looked while letting out a soft moan.

Her breasts were rising and falling as her breathing got faster. I leaned in as far as I could, but could only see as far as her flat stomach and belly button.

My cock was now so stiff it hurt. I gently pushed on the door and saw more of her in the mirror.
Her knees were bent and apart. She had one hand on her pussy, making circular movements, and the other pumping her hairbrush into her.

She was getting louder, and her movements were getting faster. The hairbrush was really wet. Just as I thought about getting my cock out, she groaned really loud and clamped her legs together, trapping her hand on her pussy as she started to shake. I couldn't take my eyes off her as she had a fantastic orgasm.

I was running through my head all the amazing firsts, first naked woman, first orgasm, then I noticed she was looking straight at me. I tried to back away, but I was frozen to the spot.

I tried to speak, but she put her finger to her lips to shush me, and then she beckoned me in. I slowly moved towards her as she sat up on her bed.

As I got close, a wicked smile appeared on her face, and she reached out and grabbed the top of my trousers and pulled me closer.

She squeezed my cock hard. I looked down just in time to see her pull my trousers down to my knees, quickly followed by my boxers.

My cock sprang out, and it was the biggest I've ever seen it, with veins running down the shaft looking like they were going to burst. My big purple mushroom was dripping pre-cum. But before I had a chance to say or do anything, she took it in her mouth.

I watched as she started bobbing her head up and down my shaft, then I felt her tongue swirl around my helmet, which almost tipped me over the edge.

I had to look away, but that didn't help, as I saw her hairbrush sitting in a big wet puddle on the bed. Then I saw us in the mirror; there was my sister swallowing almost all my cock and squeezing my balls.

I watched as I shot my first load of cream into her mouth; she pulled away as I shot a load on her face and another on her tits. She looked up at me while stroking the last of my cream onto her tits.

As soon as the last drop left my cock, she had it back in her mouth, sucking and licking me, and as soon as it started, she stopped, looked up at me, and said, "Now get out of my room."

That was the start of something new.
