Chapter 16

Four days later, early on a Saturday morning, Penny came to Peter's room and climbed into his bed.

Mae and Lars were sleeping late they had gone to a party the night before. Peter filled his hands with Penny's buoyant, firm breasts. She lay beside him and filled her hands with his large, half-hard cock. She stroked and manipulated his lengthening organ. She sighed with enjoyment as he kissed and sucked on her stiffening pink nipples. She said, "We going to fuck this morning?"

"Ready for it?" Peter moved a hand to her pussy and gently inserted a finger. He watched her face as he explored the entrance to her vagina.

Penny smiled. "I did that myself before I decided to come in here. I even tried the handle of my hairbrush."

"Oh?" Peter slid a second finger into her...then a third, in a bunch. He pushed them to the limit.

Penny didn't flinch. "That stings a little"

"I guess you're ready." Peter withdrew his fingers from her cunt and slithered them up over her clitoris. Penny was getting juicy.

"Any time, from now on." She had his cock fully hard. Her fingers gripped and regripped its thickness as she slowly pumped.

They kissed passionately.

Penny whispered, "Fuck me!"

"In a minute. We've got to coordinate on our plan to get rid of Lars. This is the day."

Penny nodded. She continued -to tenderly stroke Peter's cock. "There's no place for him in this house now. He's just an intruder."

"I'll tell Mom to go shopping for two hours. She'll tell Lars where she's going and how long she'll be gone."

Penny smiled. "Then I go in to him and do my thing."

"Right. But before that I'll let him know indirectly that I've gone to the park to play tennis."

Penny frowned. "Think he'll really be scared enough to split for good?"

"We've got to play it straight. Be sincere."

"Umm. I'll give an Oscar performance." Penny rolled onto her back. "Now?" She drew her thighs up and clutched them to her breasts. Her wet pussy was exposed, open, ready.

Peter rolled over on top of her. "You really want it, don't you?"

"God, do I!" Penny writhed to get her hands between their loins so she could guide his cock. "Don't you? Don't play games with me."

"Sure I do!" He kissed her again. His tongue was an exciting, hot eel in her mouth.

Penny moaned and brought the head of his giant, rigid cock to her wet slit. She squirmed a bit lower as she responded to and continued the kiss. She had the head in position to enter her. She slid her hand around onto Peter's ass. She urged him in. Peter responded by easing his cock slowly into her. The glans was enclosed in her jellied sheath...Penny urged him in faster. She tore her mouth free of his kiss. "Don't be so damned careful!"

He grinned. He surged into her cunt deep DEEP!

Penny strained up to meet his total thrust. "AHHH...God, I love it!" She was gorged, bellyfull, stretched. The monster in her cunt lay throbbing, a massive club of hot gristle. "Oh, Peter, I love you!"

"I love you, too, Penny. Always have." He drew back slowly, until all of his glistening shaft was out of her except for his glans. "No pain?"

"No. It's okay now." Penny smiled. "I started taking birth-control pills a couple days ago. I ordered Mother to get them for me."

"Then brace yourself, 'cause you're going to get fucked!" Peter rammed all the way. He felt her cunt spasm and clench around his buried cock. He drew back thrust-thrust-thrust!

Penny was in heaven. The physical shock of taking over eight inches in one huge penetration was almost traumatic, but she knew she could hold it. The distension was fantastic, but it wasn't a pain sensation...more a weird inner thrumming of her cunt walls as she was stretched and filled. Oh, God! How she was filled!

Again and again and again...on and on...more and more plunges of Peter's cock...until she was panting and writhing and clawing her fingers into his ass, urging him to fuck ever faster and harder. She was taking heavy, jolting thrusts of his massive cock; the bed squeaked and quaked. Her breathing came in forced gasps. Her face mottled with the congested flush of extreme orgasmic arousal. She groaned in her climax...groaned with amazed ecstasy . wasting it to go on and on.

Peter panted with effort and lust. Jesus Penny was tight! What a hungry cunt! He started to go...He felt like his cock was a foot long. A great wracking, trembling wave of pleasure expelled a high cry of golden agony from his throat. He gouted semen into her hot, sweet cunt. He was blind to everything but the cascading rapture that shook him.

When they had recovered, long moments later, Peter said, "We've got a lot of fun ahead of us, sister of mine, twin of mine."

Penny nodded. She was still feeling the afterglow of her orgasm, it had been that strong! "We're depraved, aren't we? We've committed all kinds of incest! We're enslaving our mother...wow!" She giggled. "I love it!"

"We still have to get rid of Lars the outsider."

Penny nodded again. "I'll do my bit, and you do yours."

Five hours later, around one o'clock in the afternoon, Penny went out into the back yard where Lars was lying in the sun on the blue chaise. She wore her very brief green bikini, the Indian headband to keep her long red-brown hair under control, and green sandals.

Lars didn't hear her. He lay sweating, his skin refusing to tan. He wore a purple bathing suit too small for his fleshy hips and belly. His genitals bulged the tight cup of latex.

Penny said, "Lars, do you know where Peter is?"

Lars blinked his eyes against the sun. He sat up, leaving a coating of sweat on the hot blue plastic pad. "Umm...yeah...he had his tennis racquet. He went up to the park to practice with one of the neighbor boys...Mike, I think."

"That dumb Mike. What a retard! I was going with Peter, but not if Mike'll be around." Penny sat on the end of the chaise, next to Lars' feet. She ran her hand along his leg to his knee. "You're starting to burn."

Lars agreed. "I don't tan. You do, though." He openly admired her body. "Beautifully."

Penny smiled. "Thank you. I have a problem. I need advice or something. Could we go inside?"

"Sure. You mind me taking a bath to get this sweat off me?"

"No, why should I? You haven't got anything I haven't seen before."

"That's right."

They went inside the house. Into the master bedroom. Penny watched interestedly as Lars pushed down his purple trunks. He had half a hard-on.

"Looks like you need another hand job." Penny laughed. She boldly flipped his large, slab-like cock with her fingers.

Lars grinned. His cock grew still more. "I wouldn't turn it down." He stood naked and reached for Penny. He drew her tight against his body. "I warned you about playing games with me. No teasing!" His hands rubbed over her skimpy bikini bottom. He cupped her round, firm buttocks. He pressed his cock against her belly. The top third of it pressed nakedly, hot, pulsing, into the tanned flesh above her bikini waistband.

Penny pretended a bit of fear. "I wasn't teasing! I'll jack you off if you like."

Lars cocked his head. "I'd like a lot more." He brought his mouth close to hers. His blue eyes searched hers. "Hmm?" He pressed his mouth to hers.

Penny resisted for a few seconds kept' her lips pressed tight together then yielded and opened her mouth to his insistent tongue.

Lars made a triumphant, guttural sound. He trenched her passionately.

In spite of herself, Penny was turned on by his mouth and the hard, hot throbbing of his very thick cock against her belly. She began to play tongue games with him in the kiss.

His hands moved up to her halter string at her neck. He pulled the green cords and the bow knot came undone.

Penny pulled away from him. Her golden brown eyes were large; she appeared afraid, baffled. "How much more do you want?" Her eyes were drawn down to his massive erection. His cock was as wide as her wrists before narrowing to the small glans.

Her halter sagged loose. She put hands up to halt its slipping off her big, jutting breasts. "Don't " Lars seized her wrists. He grinned and watched the small green cups slip away from her body. The halter finally fell to the floor.

He examined her lush young breasts with gloating eyes. "A beautiful pair of tits."

"I suppose you want to get your hands on them, too...like last time."

"Sure." He pulled her hands to his cock. "And you can get your hands on me like last time."

Penny let her hands remain on his hot shaft. She looked down at the long, broad cock. She watched Lars' hands come up and claim her breasts. A shiver of excitement went through her. She slowly closed her fingers around his cock. It took both hands. She began pulling and pushing the skin.

Lars' mouth took hers again. They tongued. She was really becoming aroused. She liked his aggressiveness...and resented it. She was afraid of him, too, a little. He was built like a bull those massive shoulders, that thick chest. And above all, his power of will made her very uneasy. She broke the kiss, glanced at the open bedroom doorway, and said, "I think I should leave." She bent to pick up her bikini halter.

"Not without telling me what's bothering you." Lars went into the bathroom and turned on the water. "What's your problem?"

Penny went to the bathroom door. She didn't bother to put on her halter again. "Sex. I think I'm getting to like it too much. I'm getting so I can't control myself."

"Yeah? In what way?"

Penny drifted inch by inch into the bathroom. Lars was standing at the mirror, running a hand over his blond chin stubble. She said, "I sucked off a boy the other night and I loved it."

Lars glanced at her sharply. "All the way? You let him squirt in your mouth?"

"Yes. And I swallowed it." Penny defiantly met his glance. She had to grit her teeth to keep from smiling. If he knew which boy!

"Nothing wrong with loving to suck. You can suck me off any time you want."

"Don't tempt me." Penny made herself stare hungrily at his cock.

Lars turned off the tub water. He looked at Penny speculatively. "I said 'no games.'. "

"I know. I'm not...I'm just finding out things about myself. I don't know how to handle..."

Lars took a wide stance on the red bathroom carpet. His massively wide cock stuck straight out from his blond loins. "Let's test you. Get down on your knees, girl, and suck me!"

Penny blinked. "Hey, that's not fair." She licked her full lips. She pretended to be lured.

"DO IT! Let's see how much control you have! Let's find out if you're compulsive! Down on your knees!"

Penny thought: Just like Mother! She hung her head. "Don't make me, Lars!"

"Suck me!" He put his hands on her shoulders and pushed her down.

Penny let her knees bend. She knelt. She smiled down at the carpeting. Another minute, Lars grabbed a handful of her hair and pulled her head up. She found herself facing his cock. The small glans danced in the air a few inches from her mouth. "Please, don't make me do it!"

"You want to! You wouldn't be in here if you didn't want to!" Lars pulled her head closer. He now had both hands entwined in her long aubum hair. His grip was tight and irresistible. He positioned her lips against his glans. "Open up!"

"No " The instant she opened her lips to speak his cock was thrust into her mouth and her head pulled forward. The glans surged far back in her mouth. Her lips were stretched by the ever-thickening bulk of his shaft. Penny struggled and tried to pull back.

Lars gritted, "SUCK, DAMN YOU! YOU PRICK-TEASING BITCH! SUCK!"

Lars was facing the bathroom doorway. He saw Peter instantly when Peter came into view. Peter saw. Lars' body went rigid. He jerked away backward from Penny. He almost fell into the partly filled tub. Peter stood stunned, gaping, eyes wide. "OH, CHRIST!"

Penny spun like a trapped animal. "Peter!" She burst into sobs. "He made me do it. He forced me!" She covered her face.

Lars recovered his balance. "She's lying. She tempted me in here and told me she wanted to go down on me!! "

"I didn't, I didn't!"

Peter came into the bathroom. His face was red with fury. "YOU BASTARD! I saw what you were doing you were holding her head forcing her " He swung at Lars and hit him awkwardly on the neck.

Lars almost hit back. He ducked a second blow. "Cut it out! Stop it before I get mad!"

Peter was shaking. He almost swung again. He was panting with rage. His eyes burned. "You-you better get out of here, mister! You better leave this house and never come back!"

"Hey now hold it..."

"I MEAN IT!" Peter managed an edge of hysteria in his voice. "You can't attack my sister make her do something dirty "

Penny huddled on the floor, sobbing, between Peter and Lars. She was proud of her heartbreaking, realistic crying.

"She said she loved to suck! She "

"I didn't! He he tore off my h-halter and grabbed my b-breasts..."

"She's lying! For God's sake, Peter!"

"I know my sister! You pack up and leave! Right now! RIGHT NOW! Or I'll tell Mother! I'll go to the police! Penny's only fifteen. You'll go to prison for twenty years! You forced her to perform an unnatural act! That's perversion!"

On the floor, Penny shook with repressed laughter.

"Peter, let's talk about this "

"NO!" Peter helped Penny up. He put his arm around her. He led her out of the bedroom. He yelled back over his shoulder, "You pack up and get out in a half hour or I'll call the cops! I mean it! I MEAN IT!"

In the hall, Penny started to break up into helpless giggling laughter.

Peter whispered tightly, "Play it straight!"

Penny nodded and sobered. They went into her room. She put on a skirt and blouse. They waited, talking in low tones.

Twenty minutes after the confrontation they heard Lars emerge from the master bedroom. He yelled, "OKAY, I'M LEAVING! YOU CAN TELL MAE ANY DAMN THING YOU WANT!"

They heard him bump suitcases into the kitchen and out the back door. Penny and Peter ran to his room which had a window facing the garage. They peeked and watched Lars load the bags into the trunk of his car and drive away.

Penny whispered, "We did it! We did it! We did it!" She hugged Peter. Her eyes were dancing. They kissed wildly. They fell off balance onto his bed. The kisses turned hot and passionate. Penny snuggled against Peter. She said, "I want to go again fuck me?"

"Let's trade sixty-nine."

"Groovy!" Penny stripped off her clothes. Peter got out of his tennis outfit. Naked, they kissed again and again. His hands reveled over her youthful, firm flesh. Her hands caressed his chest, his back, and trailed fingers around to find his huge cock ready for her lips.

Penny moaned with delight and squirmed around to get her mouth on it. She straddled Peter's head and pressed her pussy down against his waiting mouth as she lifted his long, thick cock with her left hand and stuffed the big glans into her eager mouth.

They were both terrifically excited, filled with triumph and lust. Within a minute Penny's clinging lips and hot, writhing tongue had Peter's cock on the brink of spurting. Peter had his mouth glued to her puffed slit. His tongue whipped across her clitoris so skillfully she was whimpering in the golden spasms of orgasm. He snorted for air as his own climax erupted and his cock jumped, spurting, in her loving, sucking mouth.

When Mae returned in her own car an hour later, and saw Lars' car gone, she sensed something wrong. When she saw the twins and saw the glee in their eyes a weird, sickening joy seized the pit of her stomach.

Penny said, "Your boyfriend left. He packed up and he won't be back."

"Why?"

Penny and Peter exchanged glances. Peter said, "We wanted him out, and we persuaded him to go, that's all."

Penny said, eyes gleaming, "We wanted you all to ourselves, Mom. Now we won't have to share you."

Peter smiled and approached his mother. "Now we can do anything we want, any time we want." He put a hand on her bust. His fingers squeeze one of her breasts. "Can't we? Won't that be fun, Mom?"
