The fourth wall!
Just as he looked, at the fourth wall he felt the wet warm mouth full of endless pleasure close over the heated hard head of his cock. The wall blinked into life in color and he saw a scene. On the wall he saw a man who sat looking at a music book, oblivious of what was happening on the other three walls and in the room as Bob looked down and saw the bobbing head of Mona working over his ramrod cock in the flickering light and it only added to his lewd excitement and he could feel cum gathering smokily his balls. He looked at the wall again. The man's preoccupation with the book soon became evident. A close-up showed he had photographs hidden in the music book, photographs of nude men and women in various positions. He was looking at one of a woman sucking a cock and his eyes closed in obvious pleasure.
With a groan, Bob let his drink spill to the floor and his hands tangled in Mona's carefully coffered hair and his hips pumped lewdly in and out as his head fell back and he looked around at the walls of the room and felt his cock wet and lubricated in Mona's mouth. It was only then that he fully noticed that the ceiling was one huge mirror and he was seeing the movies reflected over again. He moaned his delight as he saw the wall with the cunt reflected as fingers now sawed in and out of the flaccid and well-lubricated cunt as it danced and writhed in front of him.
He turned to the wall with the man as Mona settled into a slow pulling rhythm. The man was responding to a knock at a door and getting up and letting a young girl come in the room. She was a lovely girl, one of those girls who mature and ripen early in life. She was dressed in a short mini-skirt of some kind and carded some books. It was obvious from the pantomime that followed that the girl had come for a music lesson and the teacher as signed her some songs to learn, sitting the girl at the table then left the room. The girl, pretended to study then took the instructors book to check something. The photographs spilled out on the table and the camera showed her sudden shocked reaction and she put the photos away with horror written all over her face.
With a slight sound, sucking hard, Mona let his cock slip from her mouth and she smiled at it, giving it an extra squeeze and sliding the foreskin back until it was taut. She got to her knees and boldly pulled her dress up around her waist revealing her total nakedness underneath and her softly curling triangle of black pubic hair.
She pushed him further out on the couch so that he could see her straddling his waist in the mirror above while he watched the movies all around him. He saw Mona leaning forward and her firm white buttocks jutting out as she pulled the dress up around her waist.
Bob felt he was close to having the strongest orgasm of his life. What they were doing was so insane and dangerous yet he was so hot that he thought the hell with Leo, he must know about it, to hell with him he's crazy and so's his wife, to hell with them and to hell with Carol! He felt a wild lewd jubilation as he looked down and saw Mona with her thighs spread, reaching down with one hand and holding his hard cock in place while she lowered her moist, wide splayed cunt down in his excitedly waiting cock head and began to squirm it wetly around.
The young girl on the wall went back to her studies yet the camera showed the emotions on her face. Horror changed to curiosity and curiosity mounted until it got the better of her. She took the pictures out of the song book and began quickly and feverishly to glance at each one, looking at the door from time to time.
She began to slowly shuffle through the pack of pictures. Close ups showed the various positions of intercourse the subjects in the pictures were in. The camera switched to the girls face, showing wide-eyed amazement in their expressions. The camera remained focused on her face as a slow change came over her expression. Her emotions changed from one of amazement to excitement. Her eyes drooped and dilated and showed the smoky haze of passion drift through them. She began breathing hard and the camera swung low under the table so that it looked right up between her legs. She had pulled her skirt up slightly and had inserted her finger under the leg band of her nylon panties. He could see as the camera moved in close that she was softly stroking the wet little slip of her vagina.
Bob felt his buttocks tense and his whole body grow taut and tingle as Mona slowly, teasingly, lowered herself onto his cock until it sunk up between her open thighs to the hilt. She squatted over him with her dress pulled up to her slim waist, her tongue sticking out lewdly as she began to wiggle her hips slowly as she took all her wild attractive weight on her thighs.
She was astride him, naked from the waist down and her breasts were half-billowing out of her dress as she began to undulate around, his shaft buried to the hilt in her tight not cunt. He could feel her constricting her inner vaginal muscles as the softly nibbling lips tensed and tightened spasmodically around his shaft.
His half-closed and smoky eyes looked at the screen. The girl was reacting in horror as she whirled and saw that the door was open and the instructor had caught her looking at the pictures and fingering herself. He grabbed her roughly by the arm and marched her over to a couch in the corner where he pulled her down across his knees. Her legs kick wildly behind her as he lifted her skirt up over the soft round globes of her buttocks looking like twin virgins and began spanking her through the panties with the palm of his hand. The girl kicked and screamed under the harsh pounding of the tutor, her scantily covered little buttocks quivering piteously under each cruel blow.
The camera showed a close up of the music teacher's face then a close up of her buttocks again where his hand could be seen drawing the flimsy white panties down over their delicious young firmness.
The panties are torn off as the girl pleads over her shoulder to him. The teacher is in a fine lewd rage and he shoves her to the floor and stalks to the table where the pictures lie. He goes back to the girl who cowers before him as he holds out first one picture and the next and makes demands and threats of exposure to the girl. The girl quakingly agrees and they both strip naked, the man's penis standing out like a thick tree stump.
The girl's body is young and lovely and fully developed. She stands with her arms folded in front of her huge, firmly shaped young breasts, trying to hide them. At his instruction, she's made to sit naked on the edge of a cushion on a big easy chair and, at his insistence, she's made to drape her legs up and out over either arm. He knelt down between her wide spread thighs with the camera zeroing in for a close up of her cunt just over the top of his head. He reached forward placing a thumb on either side of the narrow hair-lined slit and spread the tender lips slowly apart exposing the moist pink flesh surrounding her tiny tight cunt. The camera zoomed in closer and one whole wall became her tiny clitoris as it throbbed gently in the air just above the tight elastic cuntal opening.
Bob almost leaped out of his skin. A door opened, cutting a block rectangle in the thigh of the girl on one wall and people came into the room! He started to struggle up, taking Mona with him.
Mona shushed him and forced him down on his back, leaning over him with a lewd smile. "It's all right. Just some people come to join the show," she whispered, leaning way over him so that her breast burst free from the dress and he saw her nipple taut and dark in the flickering light and he saw shadows move, saw couples sink on couches and he looked in the ceiling mirror and saw naked thighs and breasts as bodies writhed and almost blended with the action in the movies on all the walls.
Mona began moving up and down in a slow tantalizing rhythm as she undid his tie and shirt and slowly helped him out of some of his clothes as he turned his attention back to the movie on the fourth wall. He looked just as the man's head moved forward toward the moist pink slit he was parting with his thumbs and fingers. There was a profile view now of his face and the girl's vagina with the tiny, reddish clitoris still quivering from her undulating and restless excitement. The man's tongue snaked out and the tip swiped slowly across the throbbing flesh sending the now-wet bud into a jerking hardness that brought groans of delight from those watching in the room.
