Justin Robins - A passionate family

After that, watching his sister masturbate became a nightly ritual for the young boy. And each night, Lisa seemed to become more and more aroused and more violent in her writhings as she masturbated herself, sometimes with the hair-brush handle, sometimes with her fingers. She thrashed wildly about, exposing her lust-maddened pussy to her spying brother. And each time, she prolonged her session, and Billy rapidly learned to masturbate to climax as many as three times nightly. Sometimes, after he had finished and had gotten into bed, he could hear her moaning in pleasure, long into the night.

But during the day, not a sign of the obscene nighttime acts ever showed. The routine had become almost automatic for Billy. He would take his bath, kiss his mother goodnight, then lie in bed, waiting for the sounds from Lisa's room to begin. Then he would crawl to the wall and press his eye to the small peephole, getting there quick enough sometimes to watch her undress and spread her body on the bed, where she began to lewdly tease and caress her breasts and then her cunt. The firm white moons of her buttocks bounced provocatively as she reared and bucked, while her fingers plunged deep into her hot moist pussy. Billy began to live for the nights, when his secret world became a living dream of pleasant, fulfilling lust.

Then one night, he didn't hear the usual sounds from Lisa's room, and he wondered what had happened. Had she tired of the sex game? He felt a vague disappointment, but just as he was falling asleep, feeling somewhat guilty at his own disappointment, he heard the sound of shuffling feet and hoarse whispers, and it was coming from Lisa's room! He sped to the wall and applied his eye to the hole. Bright moonlight lit Lisa's room from the window, making the figures and shapes inside it appear as shadows.

He peered closely, trying to identify the silhouettes. It seemed to be Lisa and a man. But how had a man managed to get into her room? Had he come in through the window? He watched the shadows as they stood close together near her bed, and the whispers became more discernible.

"You're so young and exciting," the man was saying in a husky tone. He cupped her face in his hands and kissed her lips. Then his hands roved her lovely, little-girl body in all its enticing nakedness. Eagerly he massaged her pert breasts and rubbed her curved buttocks, and Billy heard his husky whisper: "You are so lovely… so beautiful and sweet…" Billy heard her expel her breath in a long sigh, and he thought he saw her body shiver. Then the man took her hand and put it on his huge, erect penis. Lisa held it for a moment, then began to stroke her hand up and down its rigid length.

Billy's mind was whirling. What was happening? His own body was trembling with excitement as he watched his sister play with the cock of the stranger in her room. The man's hands were caressing every intimate part of her body that he could reach, tweaking her nipples, then running a finger down along her cunt and into the crack between her lovely tight-mooned buttocks. He made little movements with his hips so that his cock shoved deeper into Lisa's caressing hands, and at times, it touched her bare belly.

He kissed her opened mouth wetly, and Lisa moaned with lustful pleasure. He bent and his lips went to her breast, and Billy heard him sucking noisily at the nipple. He nibbled at the rubbery nubs of taut flesh until Lisa groaned in joyous pain. She was becoming more excited with each lewd move the man made, moving her hips now, pushing her body up against the hardened shaft of flesh that stood out so boldly from the man's hairy loins. His hands circled her waist to grasp her buttocks, cupping the mounds of flesh firmly and pulling her cunt in closer to his hungry body.

Then suddenly the man dropped to his knees before Billy's fourteen-year-old sister, arms wrapped about her legs. His mouth moved hotly down over her curved little stomach, leaving a lewd wet trail, and she shuddered visibly with the thrill it gave her. She appeared to swoon as his tongue probed the cavity of her navel, his teeth nibbling at her yielding flesh, and as he moved his lips downward into the sparse pubic hair that covered her youthful pussy, she gasped and moaned, loud enough for Billy to hear. She trembled as his hand went to the sensitive inner thigh and onward to stroke the underside of her tightly rounded ass-cheeks.

The man was gasping heavily, and his big hand was moving slowly toward the desire-wet crevice between her legs. She cried out "Ooooohhhh…!" as two of his fingers slid slowly up into her cunt and began to move eagerly inside her virginal slit. His breath came in rasping gasps. Lisa was obviously on fire with emotion, her whole body moving as if by the force of the hand inside her cunt, as if she were a musical instrument that was being manipulated by a master. She pushed down against the lewdly impaling fingers, then rose upward on her toes, and almost in a faint, fell against the man's shadowy kneeling figure.

His voice was slurred with desire and lust as he muttered, "My hot little baby bitch… my sweet cunt! Fuck up and down on my fingers… fuck my hand!"

Billy's cock was hard as a rock as he pumped away at it almost without thinking. His lips were wet with saliva as he watched his sister skewering up and down on the man's piercing fingers, and his young eyes were fogged with lust. He wished that he were in the other room with Lisa, and that he were doing what that man was doing. He knew he could do it, if he ever got the chance, and please his sister as much as the strange man was doing.

He watched as the man began to run his tongue along her naked flesh at the juncture of her loins, removing his finger from inside her pussy and used his fingers of both hands to spread the lips of her cunt. His tongue darted quickly inside, bringing wild gasps from Lisa's parted lips, and she moaned in unbridled joy as he began twisting his nose and mouth in the wetly sensitive flesh of her pussy. He was mumbling, "I'm going to suck you until you're dry!"

"Oh, suck it good… suck me… suck me…!" Lisa mouthed obscenely, straining to allow him maximum lewd access to her tormented cunt. Billy could hear the sucking noises as he gathered the nub of her clitoris in his mouth, and his fingers probed the inner recesses of her cunt, bringing more sighs and gasps from Lisa.

She began to buck violently and she grasped his head in her hands. She cried, "I'm going to cum… don't stop now… I'm cumming…!"

The man's head worked furiously back and forth between her trembling legs as she steadied herself above him with her hands on his broad shoulders. As her moans grew higher in pitch, she revolved her hips and writhed obscenely in the gloom, and then she suddenly yelled, "Now…! Oh, now… I'm cumming…!" And she launched into a series of gyrations that made her look like a puppet on a string, out of control.

She collapsed suddenly into the man's arms and he caught her and laid her gently on the bed. Her body was limp and perspiring, and her breath came in deep sighs.

The man stood in the moonlight, staring at her heaving young body. "Now, wasn't that good, baby?" he asked in a whisper.

"Oh… wonderful…!" Lisa sighed ecstatically.

Billy watched as the man took his huge cock in his hand, holding it out suggestively.

"I think that tonight, my sweet baby, we'll be able to get it all up inside your sweet little pussy."

"Oh…" Lisa sounded apprehensive, "… it's so big…"

"Last time, you had it almost all the way in. Tonight, I think you're ready to take it all," the shadowy figure said. He bent over and kissed her soft pubic mound, making Lisa gasp and shudder. She felt vulnerable and she wanted to feel him inside her. He thrust his finger into the tiny tight opening of her vagina, and again she gasped in pleasure.
