Behind The Bike Sheds,
Chapter 1
Donna
This story begins on a Saturday evening at Adam's mom's house. Adam's mom had a girlfriend over, whose name was Donna. Donna and Matt's mom were in the kitchen sharing a few bottles of wine between them while we all sat in the front room playing on Matt's computer games. As the wine continued to flow, Donna kept appearing in the front room and flirting with us all. She would stand in front of the TV and say things like, 'Wouldn't you rather be looking at me, than playing boring computer games?' Donna must have been at least 20 years older than us, and though she wasn't what you'd class as a beauty, she was reasonably good looking and her bubbly personality was infectious.
Later that evening, she sat down on Mike's knee and wiggled her ass in his lap. She then stood facing the TV and hitched up her skirt to show us her panties. They were 'mom panties', that covered her ass almost completely. Adam's mom wondered what was going on and wandered into the room, and Donna quickly dropped her skirt and went back into the kitchen. Adam's mom didn't see anything, but as one of Donna's friends she must of known what she was like.
It must have been another hour before Donna re-appeared, and we were about to pack up and head home. Once again she stood facing the TV with her back to us and lifted up her skirt, but this time her panties had gone, and she flashed her ass at us. She dropped her skirt back down and turned to face us.
"How's about one of you lovely boys walk me home?" We were all tempted, wondering what it might lead to, and all looked at each other. In the end Mike said he would, and we finished our game and cleared everything away.
The kitchen was on the way out and as we leaving, Donna made her goodbyes to Adam's mom and left with us. Donna was fairly drunk by this point. She hugged us all and then turned to Mike.
"So, are you walking me home then?"
Mike replied, "Of course, it's on my way" (it wasn't on his way but it wouldn't add much to his journey). She turned to Conan, Adam and I, pulled her mom panties from her handbag and facing away from Adam's mom so she couldn't see, waved them at us, then turned back to Mike and put her arm around his waist.
The next day at college, we quizzed Mike as to how it had gone with Donna. Mike told us that the walk home was uneventful, but they approached her front door, she turned to face him and lifted her skirt again, this time flashing her pussy at him and anyone else who was walking past, though as it was late, there was no-one else around to see.
She said to Mike, "Would you and your friends like to see some more?"
"We sure would," Mike had responded. Donna took out a pen from her handbag and beckoned to Mike to come closer. As he did, she grabbed his hand and wrote her cell number on it. As he walked off, she blew him a kiss.
We weren't sure what to do next, but we decided that I would call Donna that evening and see what she had in mind. My heart was pounding as I dialled her number and before it had rung more than twice, Donna picked up.
"Oh, Hi, it's Matt, how are you?" I stuttered. After exchanging greetings and me feeling more at ease talking with her, Donna eventually responded in a very disarming tone.
"I guess you're calling about my offer?"
"Uh, yes, me and the guys would love to, er, see some more of you," the words stumbling from my mouth.
She laughed, "I was drunk. Do you really think I want to show you and your boyfriends more than I already flashed at you yesterday?" I was dumbstruck. Of course she was drunk and flirting last night, and now I felt really stupid.
"Sorry Donna, we just though that after your, um, show last night, you might have been serious." After a short pause I added, "But we were all keen to see if you meant it!"
"Well that's good to hear. A group of good-looking boys like you deserve some fun, and let's be honest, there isn't much fun to be had in this shit-hole of a town. Of course I meant it."
The about turn threw me, "Um, what did you have in mind?" My mind racing with wild ideas.
"Do you know the old water tanks behind the playing fields at the back of your college?"
"Yes, I do". It was a place we knew well, as we would occasionally sneak off there at lunchtime to get away from the eyes and ears of the college professors.
"What time do you boys finish college?"
"It depends," I responded. "We all usually hang around until 5 and come home together, whether we've got lessons that late or not."
There was a long silence, which Donna eventually broke, "OK. You and the boys meet me there at 5.45 on Friday, and bring a camera, I want you boys to remember what you see for weeks to come!" (emphasising the word come with a cheeky giggle). I was taken aback by her sudden crude tone, and could only reply with a neanderthal, 'Uhu.'
"Is that all you can muster, an 'Uhu'? How's about, 'That sounds fantastic Donna, I can't wait to see you. We will be there'?"
"Sorry," my brain reeling at what might be on offer. "I wasn't expecting you to agree to meet us. It sounds very exciting and I can't wait to see you. I know I will be there, and I'm sure the rest will be too."
"That's better," she said. "Please don't tell anyone else though, just keep this between yourselves."
And before I could reply, she ended the call.
I immediately called the rest of the 'boys' (as Donna had called us) and told them what had been discussed. Adam said that he had baseball practice after college on Friday but would try and get out of it so he could come along. The week seemed to drag on interminably and we all chatted about what Donna had in mind, fantisizing about what might happen. Would flash her bush at us, as she had done to Mike? Would she let us take a picture of her? Perhaps she would flash her tits at us? Would she let us touch her? Might she even want sex with us? Friday finally arrived and as 5 o'clock came around, we all met by the exit to the playing fields, and walked over towards the water tanks. It was a warm, sunny evening and we all stood anxiously, anticipating the arrival of Donna.
At 5:40 she turned the corner. She was wearing matching green blouse and skirt and a pair of black heeled shoes and carrying a black handbag. She walked right up to us, put her handbag on the floor, and winked. I'm not sure who noticed first, but Adam, who was standing next to me, elbowed me in the side. I looked at him and he raised his eyebrows and waved his head towards Donna as if to say, 'haven't you seen'. I turned my head back towards Donna and then I spotted it, she obviously didn't have a bra on underneath her blouse, as her nipples were causing lumps in her top.
"Right boys," she smiled and continued. "Here's the rules. Stand about 10 feet away from me. No touching, either me or your cocks." Adam blushed. By now, all of our cocks were straining hard against our shorts, so her words were probably sound advice.
"Who has the camera?" Conan waved the camera towards Donna. "It's Conan isn't it?" Donna asked.
"Yes mam," Conan was always the most polite of us.
"You can take as many pictures as you like, but keep your distance, is that understood?"
"Yes maam," was all Conan could manage.
With the four of us standing at the appointed distance from Donna, she started by lifting up her skirt and flashed her panties at us. These were no 'mom panties' like we had seen before but were tight fitting and very high cut, a triangle of material covering her bush and a thin black strip running around her waist to the back. She also had a thin silver chain around her waist, as well as a silver and a white bracelet around her ankle.
She dropped her skirt back down. "You've seen my panties already boys. Would you like to see something new?" By now, the part of our male minds that deal with speech had virtually shut down to give back-up power to our eyes and cocks. We all managed to nod. Button by button, Donna slowly undid her blouse. I counted six buttons. She started at the bottom and worked her way up. With five of the buttons undone, the blouse began to fall open to reveal her chest. As she unfastened the final button, she put one arm across her chest to cover her breasts and used the other to remove her blouse which she let fall to the floor.
There she stood in front of us with her top off. There was no doubt now in any of our minds that she wasn't wearing any bra but her arm was still covering her tits so that we couldn't see them. She turned away from us and raised both arms in the air, and then leisurely turned back around to face us. Her tits were not large, but they were pert and I noticed for the first time what a wonderful figure she had. I would add 'for a woman of her age' but her slim figure would have put many girls of my own age to shame.
"What do you think boys?" The question threw us all, but I remembered what she had said when I had called her and replied.
"You look fantastic. We can't wait to see more."
"Good answer. Now what shall I take off next?"
"Panties," blurted Mike.
"Mike, isn't it, the one who walked me home?" Mike nodded. "But if I take off my panties now, you won't get to see my bush as I still have my skirt on, do you want to see my pussy again Mike?" Mike nodded again. "Then I should take my skirt of first, don't you think?"
Donna turned around again to face away from us so we could see her ass. Her panties had a black string around her waist, but at the back she appeared naked as the strap that ran down her ass was so thin as to be nearly invisble. 
She raised her self slowly back up, and turned to face us. Though Mike had caught a fleeting glimpse of her pussy the previous weekend, we could all now see it clearly, in all it's feminine glory, right in front of us. Though Donna was probably twice our ages, standing there in the open air, wearing nothing more than her high heel shoes and silver waist chain, we were all entranced by the vision of woman in front of us. Her tits were beautifully formed, her figure was svelte and girlish, and her beaver looked tight and fresh.
"That's it then. You've seen all there is to see. I'll get dressed and be on my way." To a person, and without thinking, we all let out a groan. Conan piped up for the first time that afternoon.
"Er, I've only got a couple of shots of you, would you let me take a few more pictures?"
"No." Donna said. More groans from the boys. "Unless," a very long pause, "you all strip down to your underwear for me."
"But we're out in public, just behind the college, what if someone sees us?" Mike piped up.
"So it's OK if I get caught here totally naked. But if you get caught in your underwear, that's somehow worse? Hand me my skirt would you." Donna indicated towards where here clothes were piled on the floor.
We turned to look at each other and a brief conversation ensued. Mike was appointed spokesman.
"Alright, so if we strip down to our underwear, you will let us take some more pictures of you?"
"Yes, that's the idea. A girl's got to have some repayment for the services she has offered."
As we all played sports, we'd been undressed in the changing rooms before, so we weren't ashamed as we all took of our shorts and shirts until we were standing there in our sneakers and briefs.
"Shoes and socks too", Donna instructed. Mike was just about to say what we were all thinking, that without our shoes on, we would not be able to run to safety if anyone turned up, but we all bent down and took off our sneakers.
"That's better. I can now clearly see that you've all been enjoying the show so far." With our pants off, it was apparent that we were all nursing solid hard-ons. "Let the show go on!"
"Who would like to help me with my skirt?", she asked. This time it was Mike whose hand went up first. "OK Mike, pick my skirt up and come over here". Mike grabbed the skirt and eagerly went over to Donna.
"Kneel down and hold my skirt just above the ground, with the waist open, so that I can climb back into it". Mike did as he was told. Donna raised one foot and held it just over the waistband of the skirt. With her legs once again spread, Mike's face was within a few inches of her now very visible bush and he was almost paralyzed as he stared at her. Donna slowly lowered her raised leg into the skirt. She raised her other leg and repeated the exercise.
"Now, stand up slowly, and as you do so lift my skirt up so that it is back around my waist where it should be." Mike slowly began to raise himself up, lifting Donna's skirt back up her legs. Donna wriggled slightly as the tight waistline caught around her thighs. "I can take it from here", she said, and with that she got hold of her skirt, Mike released his grip, and she pulled it back up around her waist. "You can go back to your friends now." Mike came to stand back with the rest of us.
"I hope you enjoyed the show boys. There's one last thing I need you to do before I go. All of you, put your hand inside your underwear and grab your cock. Wank until you cum. When you're cum is all over your underwear, take it off and give it to me. You can go home without any today."
Unlike before when she had asked us to undress, there was no discussion this time. We were all desperate to jerk off and within less than a minute, we had all exploded, dark patches of semen obvious on the outside of our underwear. We all stripped off our cum-soaked briefs and handed them to Donna, who put them in her handbag. She pulled out a camera and before we had time to cover ourselves, she took a picture of us all standing there, in the nude, our cocks still dripping cum.
"Well done boys. Now remember what I said, what happened today is to remain just between ourselves. If any of you go telling any stories, this picture, and your semen-stained underwear, will find its way to the college, or your parents, or your girlfriends, whoever I choose. As for me, if we meet again, you will pretend as if nothing ever happened." At this, she blew us all a kiss, turned and walked away leaving her panties sitting on the ground.
As you can tell, my memory of this day is as vivid now as it has been since it happened. You don't forget a woman like Donna coming into your life, especially when it was the start of an adventure that would span several years.
About 3 weeks after Donna's show, she called me unexpectedly. "How are you doing?" she asked.
"Oh, Hi Donna, it's nice to hear from you. I'm alright, how are you?"
"I'm very well. I was sharing a little of what happened with you boys with one of my girlfriends over a few bottles of wine the other evening, and she happened to say that she had always wanted to do something similar but didn't have the wherewithal to go through with it. She had fantasized about having a group of attractive men lust over her. You would be suprised how many women are turned-on by the idea of hypnotizing a gang of men with their bodies. I told her you and your friends were more fresh young boys than men, but that seemed to be more of a turn-on to her than the idea of some older guys. Would you be interested in Amanda's phone number?" I was taken aback. I had though that Donna would be a once-in-a-lifetime experience, but here she was suggesting that one of her friends might want to offer a repeat performance.
"For sure!" I responded.
"Don't be too enthusiastic!" Donna gave me Amanda's phone number and we wrapped up the call.
"Don't you have anything to say to me?" she asked.
"You said never to mention what happened, even to you," I retorted.
"I'll relax that rule for a minute. Now tell me, how many times have you wanked whilst thinking about me?" I was a little shocked that she would be so direct, but I'd come to realise that she wasn't one for being shy.
"Most days. And most nights. Conan's emailed us all a copy of the pictures. He didn't take many but they're an awsome reminder of how unbelievably erotic you were, and how horny you made us all. Thank you."
Donna said nothing and just hung up. Seconds later she texted me a 'winking' smiley face.
