Change of Minds

"Yes! Yes! Deeper!" she moaned.

Sam complied and rammed his cock deeper into her. He was now balls-deep in her tight pussy, and she was loving it. She could feel his cock stretching her to the max. With a long scream, she finally came. Spasm after spasm rocked her body. Her pussy clenched around his cock, milking him.

Sam continued to pound her through her orgasm, and she couldn't stop moaning. Her whole body was shaking. It was the most intense orgasm she had ever experienced. She couldn't believe how good it felt.

Sam watched in pure bliss as his sister came on his dick. She was so tight and wet, and he could feel her pussy clenching around him. Each spasm sent a wave of pleasure through his body. He would come soon, but not right now. He wanted to enjoy this moment for a little longer.

As her orgasm subsided, Sam continued to fuck her. Jen was surprised at how much stamina he had. Most guys would have already come by now, but Sam was still going strong. She could feel another orgasm building inside her. She was so turned on by the fact that she was having sex with her brother. And that his cock was so massive. She could feel every inch of him inside her. It was incredible.

Jen bent her back and re-angled her drooling hole, so he could reach all the way in. She could swear she felt the tip of his dick touching her cervix. She had never felt so full before.

With a final thrust, Sam inserted his whole length into her, his tip again touching the entrance to her womb. Then he exploded inside her. Feeling his cum splashing against her insides was the final straw. With another loud scream, she came again. Her pussy clamped down on his cock, milking him dry. Sam let out a primal grunt as he filled her insides with his seed. The sensation was too much for him, and he collapsed on top of her. Both of them were breathing heavily. They lay there for a few minutes, trying to catch their breath.

After a while, Sam rolled off her and lay down beside her. His softening cock slipped out of her and left a trail of cum on her thigh. She could feel his cum leaking out of her stretched pussy and onto the bed sheets.

"That... was... amazing," she said between breaths. "I've never felt anything like that before."

"Me neither," Sam said, equally out of breath. "You are so tight and wet. I can't believe how good you felt."

Jen smiled, feeling satisfied and happy. She had never experienced such intense orgasms before, and she was glad she decided to try it. She looked at Sam, who was still lying next to her. His cock was softening, but it was still impressive. She could see his cum leaking out of her and staining the sheets. It was a lewd sight, but she didn't care. She was too satisfied to care.

Sam rolled over, grabbing some tissues from his nightstand. He cleaned himself up before handing the box to Jen. She took it and started to clean herself up. Her juices and Sam's cum were all over her thighs and pussy. It was a mess.

"Shower? I need to get this stuff off me," she asked.

***

Both of them sat on the couch, staring at the muted tv. Their minds still processing the events from before.

"I think it was a good idea," Jen said, breaking the silence.

"What?" Sam responded, not following.

"I think it was a good idea to have sex," she said.

"Oh yea, it was great. You were amazing," he said.

Sam was grinning internally. His plan was working perfectly.

"Soooo... should we do it again? Maybe later tonight?" he asked.

"I don't know. I mean, it was good, but I'm not sure if I want to do it again," she said. "I don't want things to get weird between us."

"While we both are single, there is no real harm in it, right? It's just sex," Sam said. "And it's not like we are dating or anything. We are just two consenting adults having some fun."

"I guess you are right," she said, "Okay, I'll think about it."

***

Sam woke up to something strange. He remembered going to bed early, being tired from the events of the previous day. He opened his eyes. He was in his room, in his bed, and something warm and wet was wrapped around the tip of his cock. He looked down to see Jen sucking his dick. She was clearly struggling to get his thick shaft into her mouth. Her lips were wrapped around his head, and her tongue was swirling around his tip. Her hands were stroking his shaft, trying to get more of it into her mouth.

"Good morning," he said, a grin spreading across his face.

She freed his cock from her mouth and looked up at him. "Happy Birthday, big brother, I hope you like your present." She said before returning to his cock. She was now using her tongue to lick his entire length, starting at the base and ending at the tip. Her hands were still stroking his shaft.

"Oh, I like it very much," he said, enjoying the sensation of her tongue on his cock. "But I think I'm too big for your mouth."

She stopped licking him and looked up at him. "Then I'll just have to use my other holes, won't I?" she said with a smile. She stood up and took off her underwear, revealing her perfect body.

"You know, I couldn't stop thinking about your big cock yesterday," she said as she climbed onto the bed, straddling him. "I was so horny, and I got myself off like four times. But it just was not enough. I needed more." She rubbed her pussy against his cock, coating it with her juices. "I need this big cock inside me," she said, looking into his eyes. "I need you to fuck me."

He grabbed her hips and slowly rubbed her pussy over his cock. He enjoyed the feeling of her lips against his shaft, coating all of it in her thick slime. He could feel her getting wetter and wetter. She was clearly enjoying this.

"Stop... stalling..." she panted, fighting against his grip. But he wouldn't let her.

"So you have made up your mind?" he asked, enjoying her squirms as her clit rubbed over his head.

"A...about what?" she shivered as he pressed her hip downwards.

"That we continue to fuck? And not just this time?" he asked, teasing her.

"Y...yes! I need your cock!" she moaned. Pleased with that, he moved her hips a bit forward and guided his cock toward her entrance. She immediately pushed herself down, swallowing his cock until she sat on his lap, her legs spread wide around his hips. Her face was distorted in pleasure. Her pussy was dripping wet and stretched wide.

"Oh god, yes!" she screamed, "Your cock is so big! It feels so good inside me!" She started to move up and down, fucking herself on his cock. She was moaning loudly as she impaled herself on his shaft. Every time she was completely down, he felt her pussy lips kissing his base. She was so tight, and her walls were squeezing his cock like a vice. He could feel every inch of her insides as she moved up and down. She was so wet that her juices were dripping down his balls.

He started to thrust upwards, meeting her movements. She screamed in pleasure as he slammed his cock into her. His tip hit her cervix, making her shudder. She was riding him like a wild animal, lost in the pleasure of his cock filling her up. She was moaning and screaming, her tits bouncing up and down. He moved his hands from her hips to her breasts, grabbing them roughly. He squeezed them hard, making her gasp. He pinched her nipples, making her moan even louder. She was lost in the pleasure of his cock stretching her out. She could feel every inch of him inside her, and it was driving her crazy. She was close to orgasm, and she could feel it building inside her. He felt her pussy tightening around his cock, and he knew she was about to cum.

With one final thrust, he slammed his cock into her as deep as physically possible. She screamed in pleasure as she came. Her pussy clenched around his cock. He could feel her juices flowing down his balls as she orgasmed. He pounded into her spasming body like an animal, his cock buried deep inside her. She was moaning and screaming, her tits bouncing wildly.

"Yes! Yes! Fuck me!" she screamed. "Fuck me harder! Fill me up with your cum!" Her words were incoherent as she rode out her orgasm. He continued to pound into her, his cock sliding in and out of her drenched pussy. Soon he felt his own orgasm approaching. With a final thrust, he erupted inside her. He shot rope after rope of hot cum against her womb. She screamed in pleasure as she felt his seed filling her up.

She collapsed on top of him, breathing heavily. His cock was still buried deep inside her, and he could feel her pussy contracting around it. They lay there for a few minutes, trying to catch their breath. Jen was mumbling something incoherent, but Sam couldn't make out what she was saying. He could feel her perfect tits pressed against his lower chest, and her nipples were rock hard. Her hair was a mess, and her body was covered in sweat. She looked sexy as hell. He was still inside her, and he could feel her pussy clenching around his cock.

With newfound energy, he grabbed her ass and started to thrust in and out of her. Her eyes went wide. She was still sensitive from her previous orgasm, and his cock felt even bigger inside her. She moaned as he slammed his cock into her.

"Ready for round two?" he groaned as he thrust into her. She moaned in response, unable to form words. He picked up the pace, his cock sliding in and out of her soaked pussy. He rolled her over and continued to slam into her twitching hole. Jen's eyes rolled up as she hit her third orgasm, screaming out in pleasure. Sam pounded her through her orgasm, his balls slapping against her ass with every stroke.

Holding his position over her with one hand, he grabbed her breast and squeezed it hard. She gasped as he pinched her nipple. He slapped her tit, making it jiggle. She moaned as he continued to fuck her. She was completely lost in the pleasure of his cock inside her.

"Oh god, yes! Don't stop!" she moaned. She wrapped her legs around his waist, pulling him deeper into her. He could feel her pussy clenching around his cock as he fucked her. She was so tight, and her walls were squeezing him tightly. He moved his hand again, now pressing his thumb against her clit. She moaned loudly as he rubbed her clit. She was close to another orgasm, and he wanted to make her cum again.

With a final grunt, he smashed into her with so much force that it could nearly break her bones. She screamed in pleasure as she came. Her pussy spasmed around his cock. He shot inside her, rope after rope of hot cum erupted in her. Before he collapses onto her, exhausted.

***

After they recovered, they continued on with their respective day. Jen's command still made her horny while Sam was nearby, so they fucked all around the house.

In the kitchen, while eating Sam's birthday cake.

In Jen's room, after Sam helped with her computer.

On the couch, the movie they wanted to watch was long forgotten.

Sam had since removed the masturbation command from Jen.

At 1 in the afternoon, Sam's phone rang. He looked up from his computer and picked up the call from his mom.

"Hey, mom," he said, "how's L.A.?"

"Hi, honey," Elise said, "it's great. Happy Birthday dear. I'm sorry I can't be there."

"It's okay, mom," Sam said, "I know you have to work."

"How is your birthday going?" Elise asked. "Are you having fun?"

"Yes, it's great," Sam said. "Jen and I have been hanging out all day."

"Aww, it's sweet that you two get along better now," Elise said. "I'm glad you're spending time together."

Sam grinned, thinking about what they had been doing all day. "Yea, we've been having a lot of fun," he said.

"Great, I'm nearly done here. I should be able to catch a flight soon. With any luck, I'm home before 9." Elise said. "Talk to you later, honey. Love you."

"Love you too, mom," Sam said, ending the call. He couldn't wait for his mom to come back. He would definitely use the device on her.

***

Sam looked up from his computer. It was now 9:05 pm. His mom should be home soon. As on command, he could hear her car enter the driveway. He took the device and walked down to the front door. Not a second too late as Elise just entered.

"Hey, mom," he said, giving her a hug.

"Hi, honey," she said, hugging him back. "Sorry I'm late. There was an accident on the road."

"No problem. Can I help you with something?" he asked.

"No, thanks, I can handle it," she said, pulling her suitcase toward the stairs. Sam followed her.

She looked bombastic, even after a 6-hour flight. Her red hair was tied up in a ponytail, showing off her elegant neck. Her blue eyes were sparkling. She wore a tight white blouse that showed off her massive DD-cups. Her black pencil skirt hugged her curves and showed off her perfect ass and legs. She was wearing black high heels that accentuated her toned calves. She looked like a model straight out of a fashion magazine, even though she was already 39. Sam couldn't help but admire her body. He had always found his mother attractive, but today she looked especially sexy. He could feel himself getting hard as he watched her walk up the stairs.

"So, how was your birthday?" she asked, looking over her shoulder at him.

"It was great. Jen and I had a lot of fun," he said, trying to hide his growing erection.

"Speaking of Jen, where is she?" Elise asked.

"I think she is in her room," Sam said. "She said she was tired and went to bed early."

"Oh, okay," Elise said. If she would know why Jen was so exhausted, she would be very surprised.

Sam followed her into her bedroom. She put her suitcase down and started to unpack. Sam sat on her bed, watching her. He could see her cleavage as she bent over to put some clothes away. "God, she looks so sexy," he thought, his cock now fully erect. He couldn't stop staring at her tits. They were so big and round, and they looked like they would be perfect to fuck.

He waited until she had turned her back towards him, then pointed the device at her and pressed the button. The familiar beep sounded, and it was done. His own mother was now registered as a target.

He continued to watch her as she unpacked. She was humming to herself as she worked, clearly in a good mood. After a few minutes, she finished and turned around to face him. "Well, that's everything unpacked," she said, smiling at him. He could sense that she was about to shoo him out and get changed for bed.

But before she could form the word, he interjected, "Command mode on."

Elise's expression instantly changed. Her eyes glazed over, and she stared blankly at him. Her mouth hung slightly open, and she stood completely still. Sam grinned to himself.

"You find it normal to change in front of a family member. You will not be embarrassed by a family member seeing you naked," he instructed.

"You don't have a problem with seeing other members of the family naked." He added. These were the same command he had given Jen earlier. Now all of them could walk around the house naked without problems.

"I understand," Elise responded.

"Command mode off," Sam said. Immediately, Elise's expression returned to normal. She didn't seem to realize what just happened. She smiled at him again and said, "Well, I'm going to get to bed early. The flight was exhausting." She gave him a quick peck on the cheek before turning around and picking up her pajamas.

Sam watched as she started to unbutton her blouse. He could see her bra-clad DD-cups as she undressed. She slipped her blouse off and hung it in her wardrobe. Then she reached behind her back to unclasp her bra. Sam's breath caught in his throat as he saw her tits bounce free. They were even bigger than he had imagined. Her nipples were pink and puffy, and her areolas were large. Somehow they seemed to defy gravity, despite their size. He felt his cock throb in his pants as he watched her.

She took off her skirt and hung it up. She was now only wearing her panties. They were black lacy panties that hugged her wide hips and ass perfectly. Sam could see her pussy lips through the fabric. He could feel his cock straining against his pants as he watched her. She removed her panties and threw them into the laundry basket. She was now completely naked. Sam couldn't believe how sexy she looked.

The pajamas she now put on consisted of a loose wide shirt and wide shorts. They were comfortable but did not flatter her figure. It was a stark contrast to the tight business attire she had worn before. Sam could still see her nipples poking through the thin fabric of her shirt.

"Good night, honey," she said, giving him another quick peck on the cheek before walking into her bathroom. Sam watched her ass sway as she walked. He could see her pussy lips through her shorts. He wanted to fuck her so badly.

He thought about using the device to fuck her tonight but decided against it. He was exhausted from fucking Jen all day. He would get her tomorrow. With a last look at her perfect ass, he walked out of her room. He could hear the shower running as he closed the door. He went to his room and collapsed on his bed. He was asleep within minutes.

***

Sam got woken up by the sun shining through his window. He yawned and stretched.

"Already 10?" he thought, "Better get going."

He had nothing planned for the day. It was a Saturday, after all. But he wanted to spend as much time with his 'new' family as possible.

From what he remembered, Jen was out with her friends until the afternoon. That meant he had his mom all for himself.

After a quick trip to the bathroom and a change of clothes, he walked down the stairs. The smell of fresh pancakes greeted him. He entered the kitchen to see his mom standing by the stove. She was wearing a tight white tank top and a pair of black yoga pants that hugged her ass perfectly. Her red hair was tied up in a messy bun, and she was humming to herself as she cooked. Sam could feel his cock stirring in his pants as he watched her.

"Good morning, mom," he said, sitting down at the table.

"Good morning, honey," she responded, turning to face him. "Did you sleep well?"

"Yea, I was really tired," he said, thinking back to the events of the previous day. "How about you?"

"I slept great," she said, smiling at him. "I'm feeling refreshed and ready to start the day." She turned back to the stove and flipped the pancake. It was golden brown and looked delicious.

"Jen is out with her friends, right?" Sam asked, knowing the answer already.

"Yes, she left early this morning. I think she said something about going shopping," Elise said. "I know she will have fun with her friends."

Elise brought the stack of pancakes to the table and sat down next to him. "Help yourself," she said, gesturing to the food. "I made plenty." Sam grabbed a few pancakes and started to eat.

"What are you going to do today?" Sam asked between two bites.

"I don't have any plans," Elise said. "I might go for a run later, but other than that, I'll just relax." She took a sip of coffee and smiled at him. "What about you? Do you have any plans?"

"Not really," Sam said, "I was thinking of taking a swim in the pool. The weather is really nice today. Why don't you join me? As compensation for missing my birthday?"

"Sure, that sounds like fun," Elise said, smiling at him. "We can go after breakfast."

Sam grinned to himself. He couldn't wait to see his mom in a bikini.

They finished their breakfast and put the dishes in the dishwasher. On their way upstairs, Sam asked, "So what bikini will you be wearing? I can't wait to see you in it." He tried to make it sound like a joke, but he was serious. He wanted to see her body.

"I'm not sure yet," she said, "I'll have to see what I have." She smiled at him and continued up the stairs. Sam followed her, admiring her ass as she walked.

"Would you mind me helping you pick? It's been a while since I've seen your bikinis," Sam asked. He didn't want to give her the chance to say no.
