The sight of the naked young woman on the screen made Joan wince with sudden, acute embarrassment. As she watched, she tormentedly remembered her own masturbation in front of young Wayne last Wednesday, and her same wanton disregard for common decency as this girl was portraying now. She blushed slightly as shame flicked through her conscience, and twisted her buttocks down in the chair as though she were trying to bury her guilty loins.
"Cl-Class," Joan uncontrollably gasped out loud to her students, "This… this is not the film I had for you. I…"
"What difference does it make, Miss Frazer?" Mickey asked from near the back of the room. "We can see the picture about glands next week."
"Sure," Lucy Hamilton chimed in where she was next to Knuckles. "This one looks as if it might teach us something."
"You don't want to stop it, do you?" Wayne said to her in a low, almost threatening voice. "If I were you, I'd let it run."
Joan glanced over at the handsome youth and caught the wicked gleam in his eyes. A defiance rose in her as she considered the disrespectful tone of his voice and the implication that he could tell her what to do in or out of her own classroom. But then came the warning voice in her mind: two more weeks. That's all you have to suffer through, just two more weeks… She turned her head back to the movie, afraid to say yes, afraid to say no…
The naked girl writhed more lasciviously now as though being attacked by some unseen lover. Both her hands were running over the flat plane of her quivering belly as she groaned softly at her own lust-inciting touch, until finally her fingertips came to rest at the triangle of her soft, dark-haired loins. She groaned again at the sudden contact of her hands with the moistly swelling lips between her legs, but then pulled her legs up, her toes still curled in the moss. She allowed her legs to fall wide apart, exposing to the excited film viewers all the glistening tenderness of her vaginal crevice. Her fingers crawled to the soft, hair-fringed cuntal flesh and spread them slowly apart until even the dark round hole of her pussy entrance was fully visible, and her tiny puckered anus peeked invitingly below the splayed slit.
Joan tensed in disbelieving shock as she watched the dark-fleshed girl slowly insert a middle finger into the glistening pink valley between her widespread buttocks and begin to stroke the tiny bud-like erection of her clitoris. Her sensuous movements gradually increased as her probing fingers worked themselves deeper between the hair-fringed edges, smoothly widening the wet, pink lips of her contracting cunt. Her legs jack-knifed back, knees against her breasts, and the full rounded buttocks rose and fell in response as she joined two fingers with the first and pushed all three into the hungry pink folds of her vagina. They disappeared with a soft, sucking noise, and a sighing moan of pleasure purred from her full, open mouth.
Joan was leaning forward now, her mind rebelling at the lewd spectacle of viewing a young black woman finger fucking her own nakedly squirming cunt. This picture was far more depraved and lewd than even the sex film of last week! Then she heard the mingling gasps of youthful excitement coming from both boys and girls behind her, and she turned around to see what was happening. She was not surprised to see that all their gazes were avidly glued to the film, but was shocked breathless as she made out in the dim light they were doing in the back of the room! Mickey Hagen had his hand deep up inside the unbuttoned blouse of Sharla Gronsworth, his fingers eagerly massaging her budding young breasts! Joan averted her eyes away, only to see the whiteness of Lucy Hamilton's thighs where Knuckles Gerber had lifted her dress above the tops of her slightly spread legs, exposing the smooth flesh of the girl's inner thighs!
God! She must demand they stop before her whole class degenerated into some kind of obscene orgy! But all the corrupting perversions which she had experienced since the previous Wednesday had turned Joan into a loose bundle of raw nerve ends, capable of reacting uncontrollably to the slightest sexual stimulus. The horrified teacher found herself gripped with an awe-struck immobility by the lewdness surrounding her and the pornographic film unreeling before her widened eyes.
Worse, Joan began to sense that her own flesh was beginning to involuntarily throb in response to the masturbating woman on the screen and the passionate embraces of the teenage couples. Desperately, she pressed her thighs together to cut off the unwanted tingle that had started by itself in the pit of her belly and was gradually working downward into the sensuous crevice up between her thighs. The lurid actions of the naked ducky-skinned girl and the blatant sexuality of the boys and girls were causing tiny licking flames of renewed desire to flicker hotly through her blood despite her unwillingness to allow the eroticism. She could feel small pin-pricks of delightful sensations racing through her pulsating breasts, hardening her tender nipples into chip-like projections against the thinness of her brassiere, and she could feel the heat of her breath rushing from her flared nostrils as she became increasingly stimulated.
Her nerves were shattered and her mind whirled in indecision. She knew that no matter what young Wayne threatened to do to her, she had to halt this obscene film before things ran away with all of them. Events had already gone much too far, and Joan's face crimsoned as she thought of Mickey's fingers digging cruelly into Sharla's firm little breasts. The lewd thought sent another electric tingle deep into her belly, and she could feel the warm wetness between her thighs increasing with every passing second.
Oh God, she had to get up and switch off that film! And yet… she couldn't seem to force herself to make that necessary move. Perhaps, she rationalized, it would be all right for a little while longer. The petting of the adolescent couples behind her wouldn't hurt anything so long as it didn't go any further, and she could always stop them if it did. She would sit, she decided… but only until the delicious tingling between her wettening thighs subsided. Joan turned her attention back to the movie, waiting in anticipation and nervous – fear of her own ragged emotions to see what would happen next… The dark-skinned girl on the mossy ground had become possessed by now. Her eyes and teeth were clenched as she writhed beneath her own driving fingers in uncontrollable passion. The rapid rhythm drove moans of pleasure from deep in her throat as her fingers sank into the tight, pink opening of her cunt, making moist sucking sounds as she withdrew them to push them in again. Her face had darkened as she strained for her rising climax. She groaned in frustration as her own fingers fucked harder and deeper. They were not enough, and her head rolled from side to side on the ground, her long dark hair flying in frustration at the inability to bring herself to climax. Still she tried, her hand beating a wild staccato against her wantonly writhing buttocks, the groans faster and louder with each surging thrust.
Suddenly a giant German Shepherd dog ran into the range of the camera and leaped savagely toward the girl. The Negress' eyes widened in terror, and she jerked the back of a hand to her mouth to keep from screaming. She moved to lower her legs and protect herself, but the dog had already reached her and was growling viciously in warning. The young woman froze in the position of masturbation, her thighs spread and with her knees still drawn up to her chest. She didn't dare move as the huge beast growled menacingly over her, his great panting head just above her defenselessly unturned loins.
Joan had jumped when the dog had bounded into the clearing. Her nerves were already on edge, and the sudden rush almost frightened her out of her wits.
