It was almost eleven when Cathy got out of the livery service car and walked carefully to the door to her house. She walked carefully because she was sore. Her little pussy had been packed nearly to bursting by Terry Dunn’s adult prick and for all she’d enjoyed it, now she ached.
Carefully also because most of her other muscles were tired from the repeated clenchings and spasms of her nearly constant orgasms. She still couldn’t quite believe how hard she’d cum when she’d lain atop Julie, their tongues lapping at each other’s clitoris, while Terry plunged his big dick impossibly deep into her cunt. It’d felt like his cock was going into her stomach.
She let herself into the house. Her grandmother was fast asleep, of course, and her mother and father were out at some benevolent association meeting. Was her step-brother home? She doubted it; the house was too quiet. Just as well, she thought. She wanted nothing more than a long, hot soak and a good night’s sleep.
A half-hour later, skin tingling from the nearly scalding bath, feeling cleansed inside and out and exhausted, Cathy crawled into bed and was asleep almost as soon as her head hit the pillow.
It seemed only seconds later when she was waking, restless and still sleepy. Her eyes opened, and she was staring at her step-brother, leaning against the closed door of her room, his arms folded. He was watching her.
“Tim! What are --”
“Shut up.”
His tone silenced her as much as his words.
“Reena came by the schoolyard last night. She sucked off Billy, Joe, Arthur, and me.”
Cathy was still blinking sleep out of her eyes.
“She said she learned how to do it by watching her step-sis and mine. Is that true?”
Cathy immediately knew that Reena had seen her the night before — with Reena’s step-sis and father. “It’s none of your business,” she said softly.
“Of course it is!” he snarled quietly. “I won’t have my baby step-sis going around --”
“Why not?” she snapped at him.
“Because you’re my step-sis --”
“Reena is someone’s sis, too.”
“That’s different! She’s more mature and --”
Cathy was shaking her head. “That’s not what you mean. You mean she’s got big tits.”
“Well...”
“So if I had big tits, it wouldn’t bother you if I sucked cock? If Reena was your step-sis, you wouldn’t mind if she sucked cock?”
He smirked. “If Reena were my step-sister, I’d want her to do it — with me.”
“So you don’t care if it’s your step-sister as long as she has big tits.”
His face reddened. He’d talked himself into a corner, and he knew it.
“It wasn’t Reena’s boobs that got you off last night,” Cathy said earnestly, angrily. She began unbuttoning her pajama top. “It was her mouth. She’s got a good mouth, doesn’t she?” She sat up all the way, pulling the pajama top off, revealing the tiny lumps of her breasts and the swollen nozzles of her pert nipples.
“What are — what do — what --?”
“I know she’s got a good mouth. When we licked each other, I thought her tongue was going to make me catch fire.” She unsnapped the waist of the pajama bottoms and thrust her hand inside, down over her pussy. She felt the moisture starting as she slipped her finger into her tiny cunt and let the ball of her thumb brush her clitoris. “She really liked licking me, too, and she said I tasted wonderful.” Cathy withdrew the hand from her pajama bottoms slowly, watching her step-brother’s gaze follow it. She brought her finger to her mouth and licked it. “And I do. Want to try some?”
His confusion immobilized him. His mouth opened and closed without words issuing. Cathy skinned the pajama bottoms off and lay back, naked and spread before her step-brother.
“Come over here and lick me, big step-brother, and then I’ll suck you off — and then you can tell me who’s got a better mouth.”
She could see the lump in his jeans.
“Come on, Tim. I’m not some make-believe bimbo in a magazine, and I’m a lot better than your fist.” She began playing with her nipple with one hand; the other hand was back between her legs.
He took a step forward haltingly, as if he were a marionette whose strings were manipulated by a careless puppeteer.
“Come on, Tim. Do a good job and maybe you and me and Reena can get together. Come on.”
The bed creaked as her step-brother crawled between her legs, his breath hot on her thighs. “What — how do I --?’
“First,” she sighed, “just kiss it...”
Her step-brother had been slow on technique, but got high marks for tenderness. He’d finally confessed he’d been afraid of hurting her; because she was so tiny and hairless, he’d treated her as if she were fragile. It had been exactly the kind of tonguing she’d needed. Her hot, sucking mouth had been exactly what he’d needed — three times. Only the last time had he lasted more than two minutes.
Taking a deep breath, she dialed Reena’s number.
“Hello?”
“It’s me.”
“I don’t want to talk to you.”
“You come over and talk to me, or I go over there and talk to everyone.”
She heard Reena mulling that one.
“Reena, we’ve been bestest friends since fourth grade. Please — we need to talk and — and — I miss you.”
Reena sighed. “I — I kinda miss you, too. Uh, who’s there?”
“Just me and my step-brother. Mom and Dad and Grandma are out in Great Neck looking at some more property.”
