Tales of Helen and Lisa By Sam James Chapter 5 - The Swimming Party HELEN had the afternoon off and we were supposed to be going out, but when I got to her apartment there was a change of plan. As part of her PE schedule Lisa had a swimming class at the lake and, because of bad weather the previous day, the class had doubled in number. Helen had offered to help Lisa manage them all and would I like to go along and watch? I wasn't too keen, but when Helen cunningly informed me that they were all senior girls in the 16-18 age range, I decided I could put up with it. I made myself comfortable on a rug on a grassy knoll, just above where the girls were clustering near the diving platform at the deep end of the lake, and for some 30 minutes I enjoyed the view as Lisa and Helen, both superb swimmers, gave instruction to the whole group . Then they began to take the girls for individual tuition, leaving the rest of the class to practice on their own. Soon one of the group, who seemed slightly familiar, came away from the group and began to walk towards me. As she got near I saw it was a girl who had stopped to talk to me once when I was fishing, before I met Helen. I was always polite but formal with any of the girls, because I would not have been welcome to fish the lake had I "chatted up" a pupil. But I did remember this girl because she was a good-looking, strongly-built redhead, though she had been too well-clothed at the time to identify any muscle. Now, in her sleek one-piece bathing costume I could see the sinews playing across her shoulders and the swell of remarkably big biceps for a 17-year old. She gave me a warm smile, "Hi, it's Mr James, isn't it ... Miss Troy's fiancee? I'm Lynn ... I met you fishing earlier in the summer". (I wasn't actually engaged to Helen, but she used the term to give my presence at occasions such as this more legitimacy). We shook hands and I invited her to sit down, not quite sure how to play this one. "You leave this term, don't you" I asked, "Going up to university?" "Yes, I'm taking physical education at Granchester ... I hate this swimming, though, I'd rather be doing my special strength training with Lisa... Miss Brandt". It took me a moment to realise who she meant, I hadn't used either Helen or Lisa's surnames for a long while. "Oh, Miss Brandt gives you strength training, does she?" I asked, intrigued to know more. Lynn's eyes took on an excited gleam. "Oh, yes, Granchester has a women's powerlifting team and Miss Brandt says that with a bit of training I'm good enough to join it. "Well, Lisa .. Miss Brandt ... is the right one to teach you that" I smiled and Lynn laughed, "Oh, I call her Lisa when we're working out together...we're good friends". This was getting very interesting and I decided to push it a bit further. "From the look of your biceps you could take up arm wrestling as well" I said with a jokey laugh. She looked down at her right arm and gave a small, quick flex... the muscle swelled and I only just stopped myself from leaning forward and putting my fingers round it! She said, "Oh, I already do that, it's part of my training. But none of the other girls can give me any competition, so I have to arm wrestle with Lisa. She's very strong, but I usually beat her". She gave me a sly smile , "In fact I could always put her down, but sometimes I let her win ... don't tell her, will you!" I realised that Lisa was playing games again, because I knew that if she unleashed her full power against Lynn, this cocky 17 year old would find her big biceps about as effective as Jell-O. Suddenly my thoughts were interrupted as Lynn said, "I say, would you arm wrestle with me, we can lay face to face on the rug?" I gave a gulp and looked round .... Helen and Lisa were busy down at the lake, no one seemed to have noticed Lynn's absence and, well, she had suggested it, hadn't she? I already had my excuses ready! We took our positions and locked hands. Even relaxed her bicep looked massive and as she applied pressure it suddenly stood out and I couldn't resist reaching out and closing my left hand round it. I gasped when I felt the rock-like hardness under my fingers, and said in genuine admiration, "My God, you're big, this is going to be one hell of a match!" Her eyes gleamed with challenge and she said softly, "Big enough and strong enough to put you down, can you handle that?" For several seconds we lay at stalemate, testing each other, and then I felt a surge of power and my arm was being forced down and I couldn't stop it. Her strength was incredible, but I fought back and brought her to a shuddering halt ... she had been admiring her bicep, and now she looked up at me with a shocked expression. I could see her tongue clamped between her teeth as she struggled to finish me, but inch by inch I brought her back to the vertical - and past it. Her smirk of triumph faded and an expression of disbelief and near panic crossed her face. She gave a little moan and I saw her stretched out body suddenly begin to writhe. Her arm and shoulder muscles stood out, rippling and coiling as she strained desperately to stop my advance. With a fantastic display of sheer animal strength she brought me to a halt and as my arm began to ache I realised that if I didn't finish it soon she would win. Exerting everything I'd got I began to take her down and as I did so her head fell forward, she gave a whimpering gasp and her body began to tremble. Suddenly her arm collapsed and she went face down on the rug, her body twitching and shuddering and her fingers clenching and twisting into the cloth. And I realised with total shock that this 17 year old was having an orgasm! After about a minute she raised her head and looked at me, pink with embarrassment," I ...I'm sorry" she gasped. I said, "That's one hell of a way to enjoy being beaten". Her flush deepened . "It's the first time ...." "...that you've lost an arm wrestle, you mean?", I finished, with a grin. "She relaxed and laughed, "Er, both actually!" "That was a fantastic fight, you're one of the strongest women I've ever met", I said, with genuine admiration. She looked straight at me and in her eyes was an expression of sheer sexual hunger. "I'll get my revenge, never fear!". I think that we would have been away and up into the woods, and to hell with the consequences, if at that moment Lisa had not come striding up the slope breathing fire and brimstone. Lisa ignored me and glared at Lynn. "I know you don't like swimming, but you're not supposed to run off like that". "Sorry, Miss Brandt", Lynn dropped her eyes in contrition, and Lisa said "Right, report back to Miss Troy, and don't play hooky again!" I waited for the explosion, but it didn't come. Instead Lisa regarded me solemnly for a moment and said, "I saw you arm wrestling... it's time she had more competition, did you beat her? I nodded, and Lisa smiled with satisfaction, "Good, she's too cocky by half and needed a lesson." I said innocently, "She told me that she arm wrestles with you...and that she often beats you!' Lisa gave a thin smile, "Yeah, well....." "She also said she sometimes let's you win.....". Lisa's smile faded. "Oh, did she! That girl's got a mouth bigger than her biceps! But she's good, and one day we'll see her name in the record books." Then I had a thought. "Why don't you match her up against Helen, that would be one hell of a battle!" Lisa regarded me with a patient expression. "Not a good idea, Sam". I looked surprised, and she went on, "Helen's very proud of her physique, and she happily admits that she's not quite as strong as you. But she's never quite come to terms with the fact that I can overpower her ... how do you think she'd react if she was wiped out by a 17-year old schoolgirl?" Lisa was right, and as we walked down to the lake I felt pleased that she had shown such compassion for Helen. I put my arm round her, gave her a hug and kissed her on the cheek. I felt her hand slide up between my legs and take hold of my testicles ... and then she squeezed until I howled. "I'm not all sweetness and light, you know" she said cheerfully.
