Sexy Fun Times/Ten/Girl/Gym

Your BFF Amy told you that the new gym has a special offer for under twelves on Saturday morning, so you are going together to investigate. They have taken over a shop just off the High Street. You meet Amy outside and follow her in, feeling a little nervous because up to now, the only gym you've ever been in is the one at school.

There is a reception desk, and a nice lady takes down all your details. She tells you that the first session is free and if you like it, you can sign up for a very reasonable price. Once inside, you both get changed into shorts and T-shirts and put your outdoor clothes in a locker.

The gym is not all that big, but they have all kinds of equipment. A man comes over to greet you. He is tall and quite muscular, with black hair, brown eyes and even, white teeth. "We'll get to the equipment later, but you have to warm up first," he says. He gets you both to do a warm-up exercise while he talks to a couple of older kids who are already exercising. A few minutes later, a teenager comes over. The older guy is obviously his father. He starts you doing bunny jumps and some push-ups, then gives you some dumbbells to work with. After a while, he takes you around the equipment and shows you how it works.

After an hour of this, you are both tired and sweaty, so when he says that you can have a free massage you jump at it. Amy says she doesn't have time, so she goes off to change while the older man takes you into a separate room where there is a massage table. You've never had a massage before so when he tells you to get undressed and lay on the couch which is surprisingly comfortable, you just do what you are told

You hear some whispered voices but keep your eyes shut as someone comes over and pours some warm, sweet-scented oil onto your tummy. The hands that start spreading the oil up and down your chest and over your shoulders feel soft but firm and a voice murmurs nice things like how pretty you are and have such beautiful skin. With the scent of the oil, the gently kneading and stroking, and the quiet voice, you are so relaxed that you almost fall asleep. Even when the hands are massaging your budding breasts, it just feels natural somehow.

You're told to turn over and some more oil goes on your back. Your senses are swimming with the scent of it and the gentle hands are roaming over your shoulders, down your spine, and then working on your legs. Each leg is oiled and manipulated from your toes up to the top of your thighs, but never quite touching the private place in between. In truth, you are so relaxed you wouldn't care anyway. Your legs are parted and you feel the hands squeezing and kneading your bum cheeks, pulling them apart and pushing them together.

The massage stops and just as you think that it might be over, you feel movement behind you. Then the hands are back on your bottom and you relax again. You feel your legs being pushed further apart and the hands working on your thigh muscles. It feels different somehow as if the angle has changed, but it's all pretty hazy. A voice says something but you don't listen, so when an oily finger slides into your ass, it's a surprise, but you assume it's part of a massage and it feels quite nice anyway. The finger wriggles about inside and you are glad you had a poo this morning.

When the finger pulls out and you feel something bigger pressing against your bum hole, you think nothing of it. When whatever-it-is slides in, it does feel a little uncomfortable, but the hypnotic voice is telling you to relax, so you do and it goes even deeper than the finger. It stays still for a while and then starts easing out, before coming back in even more. It stops eventually, and you feel some warm stuff going right inside you. "More oil," you think as your bum is suddenly empty.

You are still in a bit of a daze as you get cleaned up and dressed and feel as if you are on cloud nine as you head for the Mall to meet Amy for lunch. The receptionist asks you if you enjoyed the session, and when you say you did, she tells you that as a special offer, you can have a free pass for six months.

The food court at the Mall is an area with a variety of different vendors who share a common seating area, so while Amy chooses noodles, you settle for a burger and fries. "How was the massage," she asks as soon as you sit down.

You think about it as you unwrap your food. "It was great," you say.

"Was it a woman or a man who did it," she asks.

"I'm not sure," you say. In truth, the whole experience seems like a dream, and you are having difficulty remembering exactly what happened. "I'm going again next week. Are you?"

Amy nods. "I think I might try the massage next time."
