The weeks passed and there wasn't a day Sam didn't take at least one of the women in his life. He did consider further conquests. Mostly he watched the neighborhood wives, thinking about which ones would look good bouncing on his giant cock. The trouble was, the women already in his life kept him plenty busy.
At one point, Lakshmi mentioned that her sister's family would be staying with them for Diwali. It was a Wednesday afternoon and her hips rhythmically undulated as she rode Sam on his bed.
"What's Diwali?" Sam slapped at one of her boobs.
Joyce lay next to them in bed, her breasts and face covered in drying cum. "Sammy, you need to learn more about other cultures."
"Uh ... I'm trying, mom." He reached to his side with his hand and squeezed Joyce's left tit. "That's ... uh ... why I asked."
"It's ... oooohhhhhh." Lakshmi came on the eighteen-year-old's swollen cock. Her hips stopped for a minute, and then started up again. Her dark nipples bounced in an elliptical motion. "It's our festival ... of lights. The lights symbolize ... aaahhhhh ... victory of light over darkness and good over evil."
"Hhhhmmmmmm." Sam liked the idea of the stone conquering this sister while she celebrated light over darkness. "Is your sister hot?" Sam gently smacked Lakshmi's other boob and watched it shake. If he wasn't mistaken, her nipples were darker than before. And there was a definite swell to Lakshmi's belly that hadn't been there even last week.
"Everyone ... thinks that Laasya is the real beauty ... in the family." Lakshmi scrunched up her nose. She didn't want her poor sister to fall the way she herself had. Laasya had a loving husband and young children. The thought made her queasy, but Lakshmi's hips never stopped their motions.
"Don't worry." Sam let out an easy laugh. "I've got enough ... aaaaahhhhh ... pussy right now." He placed his hands on Lakshmi's hips. "Maybe next year we'll try something. You ... think she'll come next year for ... Diwali?"
Lakshmi closed her eyes and nodded.
"Great ... here I cuuuummmmmmm." And Sam's dick exploded in her pussy.

Joyce looked in the full-length mirror. She'd missed her period for a while now and her boobs were definitely bigger. She stood naked in her room looking at her reflection. White sunlight streamed in through her window. She'd just seen off her husband and children as she hurried them all to work and school. She put her hands under her breasts and hefted them up. She let them drop and sighed. They were bigger.
"Of course, Sammy did it," she muttered to herself. She turned sideways and ran her left hand over her belly. It wasn't her imagination, there was a slight bump. The thought that Paul had impregnated her never occurred to Joyce. Sam was beyond virile. Paul ... was not. Joyce rubbed her belly and watched in the mirror. She wasn't ready to do this all over again. It was hard enough with Sam and Bex, but to start all over?
"This is your fault, Paul," Joyce said to the mirror. "You should have known what your son would do to me."

Over the next several weeks, Mallory visited the Higgins house often for
tutoring sessions
. On a Sunday after church, while Bob and Paul golfed, Mallory found herself on her knees in Sam's room. She still wore the modest, blue dress she'd put on for church. Her red hair fell around her shoulders and her mouth pumped on Sam's hideous penis.
"How was the sermon today?" Sam stood in front of her, completely naked. He watched her pretty lips contort around his massive dick.
"Mmmmmmmmgggghhhhh." Mallory removed the penis from her mouth and leaned back onto the balls of her bare feet. "I have to tell you something."
"Okay." Sam nodded. He still had bed-head, his brown hair sticking every which way. "But keep stroking it while you talk."
Mallory complied.
"No, not that hand. With your left hand." Sam liked nothing more than to have her wedding ring in contact with his veiny cock.
"It's important." Mallory switched hands. His penis was slick with spit and her hand easily slid up and down his great length. She looked up at him, her gray-blue eyes full of sincerity. "I'm pregnant." Her face was expressionless as she waited for his response.
"Cool." Sam smiled. "Is it Bob's?"
"You know it isn't." A vertical crease formed on her pretty forehead.
"Okay. Well, what does Bob think?" Sam bent sideways, making sure he didn't pull his dick from Mallory's hand. He pulled out the drawer on his bedside table and retrieved something. He straightened back up.
"He thinks one of his sperm made it past the condom." Mallory's gaze fell. She regarded the mighty penis in her hand. A sense of power moved through her, that she could manipulate and bring pleasure to such a thing.
"Great." Sam reached down and opened his right hand. In his palm was a silver pendant with engraved floral designs on a silver chain. "Here, I got this for you. To celebrate our baby. Take off your cross and put it on."
It was tricky, taking off her necklace with one hand, but she reached behind her neck with her right hand while her left kept stroking. After a few tries, she unclasped the hook. She placed the cross in Sam's open hand and picked up the pendant. "What is it?"
"There's a hidden button here." Sam reached out with his fingers and depressed a little button, cleverly disguised at the bottom of the pendant. The pendant opened. It was actually a locket. Inside was a picture of Sam smiling at the camera. It was his school picture. "Better than that silly old cross." Sam took the locket, closed it, and bent toward her, opening the new silver chain.
Mallory moved her hand from his penis.
"Don't stop," Sam said.
"I don't know what to say." Mallory's left hand went back to pumping and she moved her hair to the side with her right hand, exposing her soft, freckled neck to Sam.
"You should say thank you. My mom helped me pick it out." Sam reached the silver chain around her neck and clasped it. He straightened up again. "There, it looks beautiful."
"Thank you, Sam." Mallory's cheeks flushed. She moved her lips to the head of his penis and took it into her mouth again. Her tongue swirled around the head, met with his salty precum.
"One more thing." Sam placed his hand on the back of her head and started her bobbing on his dick. "My mom's pregnant too. So, my dad needs to get that promotion at work. Cool?"
"Yyyyyymmmmmmnnnnn." Mallory reached her right hand up to Sam's testicles and felt their substantial weight.
"Good girl. Thank you, Mrs. Stevens." Sam looked over at the poster of Gandalf cat. Hang in there indeed. The sounds of a pretty Christian wife slurping filled the room. He tossed the old silver cross toward the trash can by his desk but missed. He was going to cum soon.

As the days piled one on top of another, Sam enjoyed the ever-expanding bellies around him. But he was in for a surprise.
Late one night, a voice interrupted Sam right as he deployed a fleet in his latest space strategy game.
"We need to talk," his sister's quiet voice said from behind him.
"What?" Sam looked over his shoulder.
"We need to talk." Bex stood just inside his doorway. She closed the door and locked it.
"Okay." Sam turned back to his game.
"Turn off your game, Sam."
With a tap of the keyboard, he paused the game. "Happy?" He swiveled his chair to face her.
"It's ..." Bex wore plaid flannel pajamas. She clasped her hands in front of her, fidgeting with her fingers. "It's positive."
"What is?" Sam cocked his head at her.
"I took a pregnancy test, Sam. I don't know how, but it's positive." Bex wrung her hands together as she looked into her brother's soft brown eyes.
"Strong swimmers, I have," Sam said in a Yoda voice.
"Stop being such a dork. This is serious." Bex stepped toward him. "I'm on the pill. I mean, I was. I just stopped today because ... well, it didn't work."
"This is great, Bex." Sam beckoned her over. "Have you told mom yet?"
"No." Bex walked over to Sam. Out of habit, she fell to her knees in front of him. "I think dad's going to freak out." She reached up and pulled Sam's pajama bottoms and briefs down. His dick sprung out.
"He'll get on board if mom tells him to." Sam leaned back in his chair as his sister's delicate hands went to work on his dick.
"Will mom tell him to?" Bex's nostrils flared as she took in his aroma. His cock had such a pull on her. Like she was a moon in its orbit. "Tell dad, I mean."
"Sure." Sam reached with his hand and gently caressed the back of his sister's blonde, satin hair. "I'll discuss it with her, tomorrow. Maybe I'll take her in the bathroom before school while you and dad are eating breakfast."
"Oh, Sam." Bex didn't need the pressure on the back of her head to know a blow job was in order. But she liked it all the same.
"I'll talk to her then." Sam pulled her mouth onto his dick. "While she's bent over the sink, shaking ass."
"Uuuugggghhhhh," Bex said. She thought that was a good idea.

Several months later, Joyce lay on her back on the bed she shared with her husband every night, her legs spread high in the air. Warm afternoon light filled the room. She lifted her head and tried to look down at her son's penis as it plowed her vagina, but she couldn't see past her belly. She had gotten very big.
"Mom, you look so beautiful." Sam held her ankles, looking down at her distended belly, dark nipples, and obscenely swollen boobs.
"Uh ... uh ... uh ... thank you, Sammy." Joyce rested her head back against the blanket and looked up at her ceiling. Wave after wave of pleasure flooded through her.
Joyce's phone rang on the bedside table. She reached with her left hand, picked it up, and held it over her rocking breasts. "Stop, Sammy. It's your ... uh ... father."
Dutifully, Sam slowed his pace so that she could talk. They were expecting this call. Sam's dick slid in and out of his mother's pussy so slowly that her enormous boobs barely moved at all.
