I had just turned 19 two weeks ago and was home alone on a Friday night watching the football on TV. My mum was out with friends and said she wouldn't be back until late. My dad had left about six months earlier and it was her first real night out for ages. She just said "don't wait up" as she was going to have a big night and let it all hang out and enjoy herself.
The football finished and I put some music on. I stared reading a forum magazine that mum keeps at the bottom of the pile out of the way. I came to a story about a guy and an older woman. I was very hard and horny at this stage so I undid my jeans, pulled out my cock and started wanking while reading on. She was telling him what to do and he was following her every word.
Knowing that mum wasn't coming home was for a while made me stay where I was and not go to my bedroom.
He had his head between her legs licking and sucking as she was approaching her first orgasm, like I was.
Suddenly I heard a voice from behind me, "Mmmmmmmmmmmmm you better put that boy away Rob, your mum will be in soon." It was Sherri, mums best friend. I quickly stopped put it away and straightened up. Mum came in after paying the cab driver, she must have stayed for a chat with the cabbie or she would have been the one to catch me.
I quickly went to the bathroom and just sat there until my embarrassment left my face. "Do you want a coffee?" mum called out from outside the door.
I said, "please, I'll be out soon." As I was leaving the bathroom Sherri was going in.
"I want to see you cum next time," she whispered to me. That really knocked me back, I looked back at her and she just grinned.
Sherri was 44, widowed. She was a very slim and petite lady and before tonight I didn't think about her, she was mums best friend and that was it. I was in the kitchen with mum when Sherri walked back in. "Wow" I thought, this is one gorgeous lady, whether it was from reading the story or what she had just said to me, I saw her in a different light to what I'd done before.
I could see her nipples were hard through her top and just thought she was still aroused at the sight of my dick. We both exchanged smiles across the table, before we all finished up and Sherri headed home and mum and myself went to bed.
I got to my room, undressed, and threw back the covers to get into bed. Lying there was a pair of black panties and knowing they were Sherri's, gave me an instant hard on. I picked them up, jumped into bed and put them to my face. They smelt wonderful and to my surprise the crotch was wet. It didn't take me long before I was shooting my load with Sherri's panties still on my face.
I got up about 10 the next morning, the phone rang and mum was in the shower, on answering it with a "Hi."
