Oops! "Where the fuck are we?" asked Boo-Ya in that morose whine of his as he lay prostrate behind me. "I don't know. Quit asking fucking stupid questions." It had been his idea in the first place but now we had actually started to tunnel under the wall, he was getting on my nerves. We knew that Pandora was available tonight. She had managed to slip a note to me using one of the Reform School guards who owed her a favour. But that's Pandora for you, always collecting favours. On the outside we had been a sort of item. Well as close to an item as a serial arsonist, who spent most of his time in custody and a hot, nymphomaniac could be. That we both liked sex couldn't be denied and when I wasn't available I had no problem with her spreading it about a bit with other men. To tell you the truth it turned me on. Boo-Ya's tunnel idea had come from our mutual and understandable desire to escape back into the real world and we had been working on it for over two months now but Pandora's note had forced the escape date to be brought forward. There was nothing she wouldn't do in bed. Her sex drive and inventiveness was amazing and it had kept us together for quite a while. So when she sent the note saying she wanted to have a group session with me and a few others, going into precise detail of what she wanted, what could a guy do? I know I couldn't have lasted another month in that place if she was going to send me notes like that all the time. She didn't know about our escape plans of course. She thought she was just sexing me up a bit so that I could have something to read whilst I practice my five finger exercises. Little did she know. I shone the torch onto the tape I held in my left hand. "OK Boo-Ya, time to go up." I could almost feel his toothsome grin. The tunnel wasn't a long one. This wasn't wartime Germany. It was only 10 feet long, starting on our side by a rubbish tip which disguised it well enough from the eyes of our warders and carefully calculated to break into the open again just 5 feet on the other side of the wall. It was only called a tunnel because of the section that went under the wall. The rest of the time it was just a very deep ditch. It took another hour to get out into the cold darkness of night, but because we were now on the other side the air smelled different somehow almost ethereal. A quick whisper down the tunnel and the other three quickly joined us to sprint to the small clump of trees growing nearby. Nobody saw us. It wasn't that sort of place. All the warders were probably grabbing a few beers in what they laughingly called their club before turning in for the night. We hid for a moment behind some bushes to check we hadn't been followed but I became worried about one of the other's mohawk hair style, you know the one that leaves the scalp bear except for this strip of rigid hair running down the centre. Well his was fairly long and just might be seen poking over the bush if one of the guards suddenly became conscientious and shone a light in our direction. So off we went to Pandora's house. She lived in a small apartment with her kid sister, which they moved into when I was sentenced to serve my time up here. As Pandora said one place is as good as any other and she may as well be near me for the duration. Finding the place was easy enough and getting in was simple. But knowing which bedroom was hers posed a problem. I wanted to surprise her and pretend it was a gang rape. She loved kinky sex games like that. So I opened one door and hit lucky straight away. The flashlight showed me her favourite teddy bear, the one I'd got from the shooting gallery a couple of years ago and I went in motioning the others to follow. We hesitated a few minutes letting our eyes adjust to the darkness then, as one, we went over to the bed. Stripping her down, blindfolding and gagging her was a piece of cake. She struggled a bit, but nothing too serious and as she was my girl I had first option. I moved my fingers down to her vagina and began a rapid stroking and probing movement. I knew she liked that and, sure enough her cunt juices soon began to flow. Two of the other guys pulled her legs apart and another two held her wrists above her head, pinning her to the covers. By then I was hot, and stripping off my pants, I stood between her open thighs and slid my rock hard penis into her quivering body. Jeez but it was beautiful. She bucked and rocked a bit but as the rhythm caught up with her she began pushing back against my thrusts. Soon I felt her vaginal muscles clamping around my cock and soft moaning noises coming from her mouth. I began spurting thick wads of sperm deep into her womb. She shuddered and then lay back. But not for long. As I withdrew I was almost pushed out of the way by Boo-Ya who rammed his prick home violently and began fucking Pandora with the energy of a steam engine. She groaned and managed to wrench her left leg free, which she immediately wrapped around his naked body. The noise level was rising now, but we were still fairly quiet. One of the others ripped the gag away from her mouth and pushed his cock between her lips. I could tell by the slapping of his balls on her chin and the soft retching sounds she made that he was enthusiastically deep-throating her. By now she was freed from the restraining hands and allowed to move around as she wanted. And move she did. With one cock in her throat and one up her cunt she writhed and squirmed against the double penetration. She gagged when the cock in her mouth exploded down her throat, as her cunt was once again flooded from the second vaginal fuck. For a moment I heard her gasping to catch her breath, and the rustling of the sheets as her body twisted and turned in orgasm. Then she was occupied once again. Boy did we have fun. My olfactory nerves were filled with the smell of sex. Pandora was sweating quite a bit by now and was beginning to take charge. Another quick fuck up her cunt and she slowly got onto her hands and knees to raise her arse high into the air. The invitation was obvious. And once again it was me that took first place. I put my hand up her cunt and let the spunk pouring from it cover my fingers. I then slid them easily into her rectum. Oiling her up for a good bout of buggery. She pushed back, already sucking on someone else's cock, and my fingers slid in up to the knuckles. I couldn't wait any longer and placing my prick against her anus pushed steadily forward allowing the length of it to slide effortlessly through her sphincter ring and deep into her rectum. She went wild. Wilder than I had ever known her go. We'd done this before, of course, many times, but this time she acted like it was her first. Bucking and squirming against my thrusting belly she worked me up to such a pitch that I couldn't hold on any longer. I began cumming hard. Pandora dropped the prick in her mouth and, lifting her face to the ceiling, howled out her orgasmic pleasure. Even as the cock, bobbing in front of her spurted it's load over her face until she was wearing a white sticky mask, which slowly dissolved into wide streams of cum to drop, in long tacky strings, from her chin onto her wildly swinging breasts. She flopped onto her back, gasping for breath. The room was suddenly flooded with light. "What the fuck's going on here?" asked a still sleepy Pandora, blinking in the light at the six of us in a state of sexual abandonment. I've always been known as a sharp sort of guy who could sum up a situation in the blink of an eye. I looked at Pandora. Then I looked down at her eighteen-year-old sister on the bed with her eyes shut in a swoon of sexual exhaustion and a big satisfied smile on her usually lethargic face. Wrong room, wrong girl. It didn't take more than a nano-second to figure. Like sister like sister… I looked at Pandora's rapidly changing expression from bewilderment to rage and did what any man would do. I pushed roughly past her and fled back to the Detention Centre as fast as I could. The soft padding of bare feet on the ground followed in my wake as the others did their best to catch up. I'm back now, safe and sound and figure, what the hell, by the time I leave this place Pandora will have forgiven me. And now there's going to be two nymphomaniacs waiting for my release. I didn't need a calculator to work that one out. Life isn't all bad.
