The thing about Karen was that she had always had a way with people. I'd seen the way she'd picked up guys and one or two girls, without them even realizing it was her picking them up rather than them picking her up. I'm still not sure how she did it though. If I'm being honest Karen wasn't what you'd call "a looker". She was quite plain looking. The only things about her physique that ever really attracted any attention was her smile and her fiery red hair but her personality was at times gravitational, like a black hole. She's the kind of girl you could walk right by on the street without noticing and then feel an inexplicable urge to turn your head and look back. Anyhow, I'm digressing.
The weekend after my birthday came and for some reason I had not seen Karen all week until after dinner. She'd disappeared off on her own after school and returned at around five, half six, gulped down dinner, showered and then buried herself in homework. It was a bit uncharacteristic for her to behave this way, especially with the start of the summer holidays being just a week away.
The next Friday as we walked to school together she pulled me into the same bushes where she had jerked me off a few days earlier, kissed me and told me to meet me at her mum's place after school. She smiled and I smiled back. Things were getting back to normal it would seem, and not a day too soon. I hadn't cum since about thirteen minutes past midnight on my birthday and as I am sure most guys can imagine my testicles were starting to ache a bit. She gave me her key, told me to let myself in and wait for her. She had something she had to do after school but she'd be there before four. I slipped the key into my jeans and we walked the last hundred yards or so to school.
Of course I knew that this was somehow all related to the surprise reward she had promised for completing my birthday dare and the thought of what Karen might have planned for us kept me in an aroused state all through the school day. I wanted so badly to slip into the restroom and jerk off a quick one but I figured that would be cheating. Not sure why I felt that way but I did. After the school day ended I couldn't get to Karen's place fast enough even though it was just two o'clock.
When I got there I decided to shower and have a snack before Karen showed up. After the shower I went into her room and slipped on a pair of her panties. They were lilac lace and silk. I thought it would be a fun, sexy reminder of the hellish dare she had put me through. After that I made myself a sandwich and sat down in the living room watching TV while I waited.
Half an hour later there was a ring at the door. I knew I hadn't locked it so I was a bit surprised that Karen didn't just come in. Was it part of her surprise perhaps? I grabbed a towel in the bathroom and wrapped it around me to hide the panties when I went to open the door. Just in case it wasn't Karen. Good thing I did because when I opened the door there was a woman I'd never seen before. She was a total looker too and already being aroused by the thought of Karen's surprise reward and wearing her panties I got a full blown erection just by seeing this total babe outside the door. She was wearing short jeans shorts and a thin white blouse under which she obviously had nothing because I could make out the contours of her nipples. Her breasts weren't all that big but holy fuck they were gorgeous. She had sun bleached blonde hair and sparkling blue eyes. In many ways she was the exact opposite of Karen.
Before I could compose myself enough to ask what she wants she asked if Karen was home. I shook my head telling her that I was expecting her no later than four though. She introduced herself as Molly and asked if it was alright if she waited inside for Karen. Still taken aback by her beauty I just nodded and opened the door all the way for her. If this was part of Karen's surprise, which it probably was, then I had to admit she had outdone herself.
I asked Molly if she wanted something to drink while she waited for Karen. She shook her head and reached for my towel. She yanked it off and smiled when she saw my rock hard veiny cock poke out of the panties.
"Damn, Karen was right."
I felt a real surge of sexual energy pulse through me despite the embarrassment of having been caught wearing panties by a completely unknown seriously hot girl. I smiled and tried not to blush too much.
