Susan Mitchell was standing in the middle of the classroom as her classmates came in. She was naked as always, her wrists bound together over her head by a chain to the ceiling. A pair of cuffs around her ankles attached to a metal bar kept her legs several feet apart. Her mouth was gagged. The students took their seats surrounding their nude classmate.
Mr. David Morgenstern walked in and addressed his advanced math class. "Before the holiday break, we were working on some of the basics of game theory. I thought we might spend some time today playing some games to work on those concepts. We have a few special versions of some basic games, thanks to the help of our industrial arts and technology classes, and of course our special volunteer, Susan." Susan felt even more vulnerable than usual, wondering what type of games the teacher had in mind.
"First, let's start with a simple children's game all of you have probably played at one time, called Connect Four." The teacher brought out a wooden box with six rows of seven holes drilled in it. Morgenstern continued, "This is, as I said, our own version of that game, but the concept is exactly identical to the one you've played. You drop disks into the slots at the top and the disks drop all the way down. Each player alternates turns, until one person has four colored disks in a row, either horizontally or vertically."
The wooden box had two hooks at the top of it, to which the teacher tied a pair of strings. He brought the box over and tied the strings around Susan's breasts, wrapping the strings around her tits so the box now dangled in front of her, suspended from her chest. Her breasts were now being compressed by the strings around their base. The box itself was not extremely heavy, but Susan still had to lean slightly forward to account for its weight, straining her arms tied over her head.
"Jill and Bryan," the teacher said, motioning to a pair of students sitting near Susan, "how about the two of you play our little game first." He showed each student a stack of metal disks, half painted red and the other half black. The teacher continued, "As we discussed in class, Connect Four is a game with so-called 'perfect information' because each player knows every move that has been made and every move than can be made. There are, however, 4 trillion possible game boards. Jill, you may choose your color and play first."
The girl picked up one of the red disks and dropped it into the center slot where it dropped all the way to the bottom. The boy placed his black disk in the middle on top of the first and the pair alternated in the middle column. Susan soon realized the metal disks were weighted and the strings around her breasts tightened as the box became heavier with the six disks already in it. She also saw that neither of her classmates seemed interested in winning the game, as they proceeded to fill another 14 slots with disks. The girl's breasts were turning purple and she was leaning as far forward as she thought she could, straining her shoulders. If she could scream, she would be yelling loudly for the pain to stop.
Ten more disks clanked into the wooden box and still no one had made four in a row. The weight bearing on Susan's tits was nearly a pound and there were still 12 disks to play. The girl leaned forward even more, the pain in her arms almost unbearable now. The students placed the remaining discs carefully, with Jill finally winning on the 41st move. Susan was whining in agony as the heavy box swayed in front of her, almost completely full. The teacher unsnapped the bottom of the box and the metal disks spilled out, clanking to the floor. Susan stood upright as the weight was relieved.
The teacher closed the box and helped the students pick up the discs from the floor. He handed a black disc to Bryan and bade him to start another game. Susan grunted behind the gag. This time, however, it seemed Bryan was determined to win and he caught Jill after she made a mistake on her seventh disc and he was able to complete four in a row with just two more moves. The third game between the pair, however, once again stretched to 47 discs, stretching Susan's abused breasts as well. After that game, Morgenstern unwound the strings from the girl's tits and Susan panted heavily as she felt the blood returning to her tortured orbs.
"Very nice set of games, you two," the teacher said as Susan tried to recover her composure. She prayed there would be no more abuse for her tits, but she knew better than to expect that.
"As you can see," the teacher continued, "Connect Four is a game that very much favors the person who goes first. Unless that person makes a mistake, they always have a slight advantage. Our next game is a little different in that the players don't have that "perfect information. They know all of their possible moves but can't see the entire board, as it were." A pair of students brought in two boxes which the students quickly saw were an electronic version of the game Battleship. "In Battleship, you have a 10x10 grid," the teacher said, "and five ships, one five squares long, one four, two with three and one with 2. So each player has 17 possible targets in that 100 point grid."
"Speaking of targets," the teacher said as two students walked in pushing a pair of devices. Susan recognized them instantly and the look of fear on her face was evident. Each was one of the whipping machines that had been used on her in the past. The first student positioned one behind her where the whip would strike her directly on her bare buttocks. The other was placed in front of her, aimed directly at her already tortured breasts. She pulled hard on the chains holding her arms over her head and squirmed in her bonds, even though she knew there was no way she was going to be able to avoid the torture.
Two students sat on opposite sides of a table, in front of the game. They started by placing the ships on their grids. The player on the far side of the table called out his first move, a miss. The other player missed as well, but then the first player was greeted with the electronic game shouting "hit". The device behind Susan spun around and brought the whip against the girl's ass and she bounced forward. The force wasn't as bad as she had felt in the past, or even the whipping she had taken last week at the farmhouse, but it still hurt.
The next eight moves were all misses but on the next round from the near side of the table, a hit was recorded and Susan felt a sharp smack across her bare breasts, right above her nipples. The players were fairly evenly matched and Susan felt an almost even number of swats against her breasts as she did her tits as the players kept calling out numbers. As the game progressed, the number of hits increased so the whip wound up quickly and struck her several times in succession. She was bouncing forward and back as the force of the whip hit her, screaming in pain with each swat, although the class only heard grunts.
The game ended with 17 hits for one player and 15 for the other, a total of 32 swats of the whip against Susan's body. The red stripes across her ass and tits were evidence of the closely matched game.
The class period ended and the students exited the classroom, giving Susan a little time to rest. The teacher came over with some ointment and spent far too much time, in Susan's opinion, rubbing it over her injured breasts and butt. But the salve and massage did lessen the pain.
