'You ye never been fucked until today!' he shouted.
'Listen, big brother, you might be big, but you got a lot to learn. I've had guys get me hotter blindfolded.'
'Sure.' Billy walked to the kitchen and got himself a Coke. Then the two girls stood in the middle of the room and started doing their exercises.
'What are you doing?' Billy asked them. 'Exercises. They're called exercises.'
'But what for?'
'So we can fuck better!' Robin answered. 'You ought to try it, Billy,' Janie told him.
'Get serious.'
'It might help you, Billy,' Janie added. 'Couldn't hurt,' Robin said. 'Listen. What do you girls want from me anyways? One minute you're telling me to fuck you, the next minute you tell me to get lost. What kind of game are you playing?'
'We're just saying you need a few lessons, big brother.'
Billy was really getting angry with them now, and he was starting to get a hard-on.
'Listen. I'll fuck both of you at the same time better than any two guys you can find!'
His words made the two girls stop. They looked at each other for a moment, knowing he was right, but they couldn't let him win, so they both broke into laughter.
'You gotta be kidding,' Robin said.
'Come an, big boy. You're not Superman, you know.'
'Then let's all get into bed and we'll see.' The girls raised their brows again, looking at each other. Those were the words they were waiting for from Billy. 'Well?' he said.
'I don't know,' Robin responded. 'You're crazy to think you can handle two of us.'
'Well, we won't know until we do it.'
'I know right now you can't,' Janie said. 'You couldn't even handle me!'
'No, I won't,' Robin exclaimed.
'Yeah, me, too!'
The girls seemed to be backing down, but actually they were teasing their naive brother.
'Oh! Now look who's backing down! The sex twins themselves!'
'Nobody's backing down,' Robin said.
'Then let's go,' Billy demanded, his rod getting hard with anticipation. Robin watched as his prick grew before their very eyes. She walked up to him and took his hardened tool in her hands.
'You'll wear it out, Billy,' she told him, and stroked it again, then let go.
'It'll tear you apart first!' he cried. His cock was getting bigger and bigger now, mid the girls resistance was wearing down. They wanted to get in bed with him more and more as his big tool grew.
'And if you don't?' Robin asked.
'Let's go!' he shouted, and he pushed the girls into the bedroom and slammed the door.
CHAPTER FIVE
Billy was the kind of man that all girls dream about. Tall, muscular, well-tanned, and very handsome. And more than that, he was a strong man, a man who knew what he wanted and went after it. He was the kind of guy that told girls how to act, and what he wanted from them. And confidence – there wasn't a person more confident than Billy was now. Having conquered his virginity gave him the strength he'd always wished he had. And last, but certainly not least, of course, he had a huge cock! When his two, sisters saw his enormous tool, they just couldn't refuse another round of fucking.
The two sisters obeyed their big brother as he pushed them into the bedroom. The very thought of a three- way orgy excited the girls as they awaited his next command. But Robin wanted to make him a bit angrier, because she knew that Billy fucked best when he was mad, when he went completely animal.
'You're a fool, Billy,' she said to him, and Billy turned to her. He held his erect cock in front of her, and Robin watched as it swelled to a tremendous size.
'No, you are,' Billy responded. 'Now who wants to be first?' He waited for an answer.
'Janie?' her sister called, and they looked at each other for a moment, trying to make a plan. Then Janie looked over at her brother.
'You are!' she shouted, and the two girls advanced on Billy and pushed him onto the bed. Billy lay on his stomach as the two girls sat on top of him, Janie on his shoulders, and Robin on his stomach.
'Wait a…' But Billy couldn't finish speaking as his sisters started tickling him all over. He felt Robin tickling his balls while Janie's hands found his armpit. Billy was laughing as hard as he could now, Robin's hands tingling his buttcheeks and his asshole, while Janie worked his very sensitive sides.
'Stop!' he cried, squirming under their soft, warm bodies, trying to free himself from their hands that were working so hard on his mast sensitive parts. Robin reached a hand down to his feet and tickled the bottom of them. Billy could have gotten up if he'd really tried, but all those hands and feet an him were feeling very sensual. All of a sudden he felt a hand reach under him and find his anxious cock, squeezing it as hard as she could.
'Ooooowwwww!' he cried, but Robin only squeezed his rod harder.
'I thought you said you could handle us, big boy,' she said in his ear.
Billy was mad. Gathering all his strength, he rolled over onto his back, flipping the girls off balance.
'All right, the games are over, you bitches!' he yelled, now very furious that they were taking advantage pf him. The tone of his voice scared the girls, and they could see the muscles in his body flexing as he reached for Robin.
'You're going to get it first, sweetheart sister!' he said, picking Robin up and putting her legs around his hips. Janie watched her brother as he manipulated Robin to the exact position he wanted her in.
'I'm going to rip your cunt wide open,' he told her.
Robin pretended to be frightened of him, but actually she was enjoying the whole thing, because the harder a guy fucked her, the more she liked it. She just couldn't ever find a guy who could fuck her long enough, or deep enough, or hard enough to really satisfy her. But she admired the ones who tried.
Robin sat on him and licked her lips as she got ready to enclose his huge prick in her hungry cunt. Her swollen nipples throbbed in his palms as he reached up and massaged them, pulling them and pinching them with his fingertips, then squeezing her entire boob in his hands. One of his hands roamed down to her belly and tickled her there a minute. Now Robin was breathing terribly hard, her forehead dripping with perspiration, her fuzzy, moist cunt mound brushing against his hard dick, anxious for him to fuck her.
Janie watched intently, for she'd never seen her sister screw before, nor had she ever seen anybody screw. The whole scene excited her as she watched her brother's cock grow to preposterous lengths. Janie felt her cunt getting wet, and, reaching down, she felt her clitoris grow hard in her fingers as she watched the two lovers enjoy each other.
Robin's pussy was very moist now, ready for Billy's tremendous shaft. She pleaded for it as Billy's wandering hand found the center of her sex.
He pushed on her sensitive clitoris and felt the excitement vibrate through his sister's young body.
'Put it in!' she cried, and arched her crotch more, landing on his eager cock.
Janie watched as his throbbing spear slipped into her sister's aching twat, fitting smoothly into her hole. A perfect fit! she thought, and she imagined how his tool felt inside her as she rubbed her clitoris even harder with her fingers.
Robin started moving her whole body around and around, her juices running freely now as she moved from side to side on top of Billy.
His face tensed as he gritted his teeth, pushing his prick farther and farther into his sister's twat, moving it in and out, back and forth, hard and fast, trying to stretch her tight cunt as much as he could.
Janie watched him as he drove his rod into Robin's box, pulling her ass tighter to him so he could fuck her even deeper. His mouth opened as he sighed in pleasure, and his long tongue flew out at the air, but there was nothing there for it to touch.
Janie couldn't stand watching her sister go wild with passion any more, and Billy's long, wandering tongue
