A bright smile swept over Tannsy's pretty face. "I'm glad you-u think so anyway," she said happily. The abrupt squirming of her hips almost drove the stiff point of his cock into her wide open cunt. Clark quickly swiveled his hips sideways, rudely dumping his tiny sister to the bed.
"Hey-y," Tannsy protested, "I wanted to do that some more. It felt good."
"No way," Clark said sternly. "We almost really did it. It almost went in."
"Would've been okay with me, hey. -Okay, okay, I know. Nothing dumb. So I liked it better when we were touching all over anyway, didn't you?"
Tannsy's nimble fingers raced over the buttons of her brother's pajama top. She rolled against him, again slipping her tiny warm hand between their bodies to encircle the base of his dick, her fingertips feathering curiously along the soft canal on the underside of it. She giggled suddenly.
"At least it didn't bend over like when we used to try-y to make it go in, hey?" she said. "God, I'm so w-wet down here, Clarkie. Is that all from me or does your thing do that, too?"
"It's from you. The girl always-"
"…. The girl always what?"
"Nothing. Forget it."
"Hey-y, come on, Clarkie. When did you and me ever not tell each other something?"
"… Right on, honey, I'm sorry.-The girl always gets real wet and slippery down there so the guy's thing'll… well, like slide into it easy."
"Well, so… sli-ide it on in then, hey?"
"Hey, knock it off, Tannsy. You know we can't go that far. You're still my s-sister even if we are… like we shouldn't even be doing."
"Oh, pee on sister. Anyway you said we re pretending I'm not your sister this one-" Tannsy clapped a hand to Clark's hip, thrusting herself hard against him. "No, don't get away. Please. I'll be good, I promise, only let's do this some more. This can't hurt anything, can it?"
Clark pulled Tannsy hard against himself for a moment, then, with a brief mental struggle, blanked his mind against the hard tips of her breasts boring twin holes into his chest. He lay carefully motionless save for his hand caressing her warm behind but his mind refused to stay blank for long against the moist thighs fucking the foreskin back and forth on his giantsize cock, the smooth rippling of the muscles in her behind going soft and firm by turns as Tannsy moved, and the warm little cotton bolster of her hand caressing the cheek of his own tingling ass.
The sweaty little smacking sounds suddenly ceased as Tannsy hunched her hips and slipped her hand between them to pull the big exciting cock more tightly against her slippery cunt. And then more tightly with each stroking. Little by little her body shifted backwards until she was frankly rubbing herself along the full length of the big exciting cock and then bunting her cunt against the end of it.
Watching Clark's face at first but quickly losing herself to this new pleasure, her toying fingers began sliding the rubbery point back and forth along the solid slit of her cunt, her lithe little gymnast body gradually shuffling around until her bottom thigh was tight along her tummy, the ankle fitted snugly under Clark's side. Biting her lip in concentration, Tannsy hooked her other heel behind her brother's knee and her hips began to come on in instinctive little rolling motions as she searched for the place that big warm wonderful thing was supposed to go into.
Clark stiffened warningly but Tannsy quickly silenced him with jittery fingertips pressed against his mouth. "Just a little bit?" she pleaded shakily. "Please?"
Clark felt his cock nestle into the dimple of Tannsy's cunt and then, to his great surprise, he felt the slippery lobes begin to spread against the blunt end. There was a little thunk feeling, suddenly, and a breath stealing feeling of shimmering wet heat around the head of his dick, and then the firm rolls of girl flesh snapped around the shoulder rim, snug and tight as a pair of rolled rubber bands.
Tannsy's eyes popped wide open. "I thought it'd be too big to go in," she chortled.
"I did, too. I couldn't hardly even get my finger in it a little while ago. Didn't it hurt?"
"N-not really hurt, no. It felt kinda funny for a minute but now it's really great. Like a great big warm-m-rubber ball, you know? it feel good for you, too?"
"Oh man, honey, like wi-ild!"
"Well, whyn'tcha- Oh nuts, Clarkie, why don't you go ahead and sli-ide it on in one time, okay? Just one time, okay? No, wait. I wanna see what it looks like first."
Tannsy curled her upper body over and Clark arched his backwards so they could both see the solid bone bridge curving over between their bodies, the end of it anchored so tightly in the overstuffed lips of Tannsy's cunt.
"God," Tannsy breathed. "We really did it, didn't we? I never thought that huge thing would really go in there."
"You sure it's not hurting you, Tann? You look like you're… about to split clear apart or something or like your whole belly's full of it or something."
"No-o, I told you. It feels… like fantastic. God, doesn't it-isn't it-doesn't it make you feel all craazy inside seeing it stuck in me like that? It sure does me-e.
Tannsy gripped inquisitively at the throbbing shaft with hands that felt like two tiny bands of white hot cotton cutting the turgid length of it. Her hands moved gently toward Clark's body and Clark could feel the foreskin of his burgeoning cock stir within the snug chrysalis of the little velvet vise. Tannsy stroked toward her own body and he could feel the same skin piling up against the tight-stretched velvet lobes of the brand new girl hole. He gritted his teeth until his gums ached.
As Tannsy's hands moved toward her own crotch, the heel of her hand brushed across the point of her supererected clitoris. Her breath caught in a sharp hiss. Her hands tightened convulsively on the big prod between their bodies and her hips swiveled against it, wedging the bulging head a tiny bit further into the tight-clinging grip of her wet little hotbox. Her pretty little pixie face bloomed with a look of surprised voluptuousness that hollowed Clark's stomach from the top of his swirling head to the tip of his suddenly catatonic cock.
His hips lurched in spite of himself and suddenly the boiling in his gut was beyond his control. He lunged at Tannsy from sideways but her satin smooth hip slipped away from his sweating hand and Tannsy's tiny body went skidding backwards across the slippery silk bedsheet, the head of his dick still stuck in her cunt. He thrust an arm behind her hips, scrambling desperately, and finally got on top of her. In a blind stupor, he stabbed his enormous rigid supercock at the brand new, never-used, virgin cunt laid out so wide open for him to take, vaguely feeling her tummy collapse as Tannsy tried suddenly to cringe away from him. Vaguely, he was aware of a tearing sensation in front of the ballooning head of his dick and of Tannsy's strangled squeal and of her head lashing no, no, no, against the headboard of the bed. But then he was hammering deep, deep, and deeper into the soulscorching heat of the whimpering little body and he was aware of nothing but his own body melting into one huge prick and then exploding, blasting his whole goddam life into the tiny tiny girl hole he was driving the spurting prick into.
CHAPTER II
Maybe she really was okay as she had insisted, in spite of the blood all over everything this morning. Even as he watched, Tannsy's tiny body did an incredibly swift whip over the lower of the parallel bars, springing into a hand stand on the upper bar that spun on into a blurred double whirling and a flying flip from which Tannsy landed lightly on her feet bare inches in front of Lorene Wilson who was standing by observing her every move. He saw Tannsy give her bright little smile of encouragement and lay an affectionate pat on Lorene's skinny ass and lead her to the bars to try the routine. As earlier, in the cafeteria, the self-assured movements of her lithe little body took on that strange new aspect of maturity that was just not his favorite little sister anymore.
