Button awoke suddenly, feeling thirsty. He sat up, glancing at the digital clock next to him. It was just after midnight. The bed he was is was comfy, better than the one he had at home. It made him consider ignoring it and going back to sleep. He was currently out on vacation with his mom, now renting a nice beach house for the week. Outside the window he could hear the sounds of waves and inside he could just make out the dolphin themed room he was in thanks to the moonlight. The beach house was a three bedroom, two bathroom place with an indoor swimming pool extending out from one side. The swimming pool was nice with sky windows and a few pool toys set up in the corner with a table and some chairs. It was the first night here and he was looking forward to trying it out in the morning then maybe hitting the beach.

He clicked his tongue, deciding to get up for that glass of water after all. He was currently shirtless and wearing nothing but boxers but it wasn't like anyone was going to see him. The beach house was far enough separated from any prying eyes, much to both Button's and his mom's delight. Made things easier to just relax.

As Button Mash got up, he glanced at himself in the passing mirror. He was fairly skinny but had a reasonable build. Eating a bit better and jogging to the arcade had helped keep him in decent shape. No longer was he a slightly chubby, short stack colt, now he had leveled up to a slightly more tall, skinny and decent looking stallion. His hair was cut short with a bit of fluff to it, looked a bit wild right now but again, who was gonna see him to care. His mom was probably already in bed anyways. Glancing at the nearby digital clock revealed it was close to midnight.

He sighed, feeling more wide awake. Getting back to sleep might be tough. He exited his room and walked down the long hallway past the bathroom and the two other rooms. His moms room had the door closed.

As he made his way to the kitchen, grabbing a water bottle out of the fridge, did he catch the sounds of something splashing. The kitchen had a window that overlooked the indoor pool. Button took a sip from his drink then glanced though the window in curiosity. He nearly spit out his drink.

Down below him, Cream Heart, his mom, was currently standing in just a bathrobe. He hadn't expected to see her awake and it nearly made him jump. She was never a late night woman.

Button wiped some water from his chin. It was no secret that his mom was a looker. Those large Double D breasts, curvy ass while still having a chunky but still good looking form. Her long hair and still fairly youthful vibe would cause any of his friends to do a double take any time she was in the room. But it mattered little to Button, he knew they would never get anywhere close to where their minds went.

Button slowly turned and crept down some stairs that lead to the basement and by extension, the pool. He was careful not to make the stairs creak as he walked down until he was facing a door that lead to the basement and another that led towards the pool. Going through it he went down a short hallway past a bathroom and changing room, coming up to a glass sliding door with a now great view into the pool room.

He watched with an eyebrow raised as the sexy woman removed her robe, revealing her hot naked body underneath. She let the fabric hit the ground and stretched out. Then with a quick jump, she dived into the water. Button gave a low whistle as she came up, water running down her long hair as she began to swim forward, breast stroking with little effort as she took in the the sounds of the waves outside though the small open windows surrounding the poolroom and the warm water inside.

The young adult quickly grabbed the handle of the door, fully intent on just watching the sexy woman do her laps. He waited till she had her back to him and was underneath the water so the sudden draft wouldn't give him away. Quickly opening the door as she dipped down and quickly slipping in before closing it. He then slowly walked around the outside, watching her as she flipped onto her back, slowly kicking and swimming backwards. She stared up at the bright moon above, clearly enjoying herself.

Button sat down, enjoying the view just as much. He had never seen her so relaxed before. Also clearly enjoying herself as well.

Just as she was about to start swimming again, she looked to her right, suddenly catching sight of Button Mash in the moonlight. She jerked a bit, suddenly moving into a standing position as she put a hand over her heart. "OH! Oh, Button, I thought you were asleep. You nearly made my heart jump out of my mouth." She let out a small sigh, wiping some water from her eyes.

"I could say the same. Though I can't say that I blame you, I was planning on trying out that pool in the morning too."

"Well." She stared at him seductively, putting an arm over her breasts as she leaned forward a bit. "You like what you see?"

Button felt his boxers start pitching a tent. "Yeah, kind of hard not too. Your hot, wet and sexy. That's quite a mix."

"Do you want to join me?" She said, a blush slowly appearing across her face.

Button stood up. "Thought you'd never ask." He grinned and pulled down his boxers, his rather large dick springing into view.

He grinned before slipping into the water with a small splash. The water was very warm, perfect for him. As he half walked and half swam with the water going up to his chest, he admired the the view in the moonlight.

The view was even better up close as he went around behind her and began to fondle those wonderful melons, his mouth gently biting into her shoulder. Cream let out a low coo of delight.

"Its funny, never would have conceived we'd be doing something like this just a few years ago but something just awakened and clicked in both of us. The need for affection and the perfect amount of love I suppose." Cream shuddered at the touch. She really did love what they had started. Not a care in the world could ever make this weird to her, this was a different kind of love.

Button felt his fingers sink into her flesh, feeling her nipples hard as a rock as he continued to squish and move them. He eyes glazed over as he smiled. "Like we are the only ones though. We've heard rumors about the Sparkle family. At least we have some tact." He slowly rubbed his dick between those wonderful legs, feeling that incredible ass push against him.

"I don't know if by tact you mean we still try to keep it a secret or I make sure to take the contraceptives' whenever you are home. Most of the time at least... Either way, stop teasing me and start pumping, I want to feel that dick deep inside me. Its all I've been thinking about since we got here."

"As you wish." Button said with a chuckle, rearing back, using a hand to guide his large member between her walls, feeling it slide deep into her. The water splashed and moved around them as he began to pull and push slowly, going back to playing with her lovely beach balls.

Cream let out a low hum. "Mhmmmm... That's the ticket. That's the feeling I just can't live without. Go on, make some waves sweetie."

Button nodded and picked up the pace, feeling the pool begin to stir around him and watch as waves splashed again the walls of the pool. She felt so good, slamming deep as her body seem to rebound slightly. Her ass looked good too, he would have to have some fun with that later as well.

He took a deep breath and started to really move his hips, bouncing deeper and deeper within Cream, hearing her moans and gasps with each trust. It was the sounds that really got to him. Hearing sounds so desperate and filled with lust as his dick dominated her pussy. In and out, thrusting over and over with splashes of water. He let out his own low groan knowing that he could not hold out long as much as he wished he could.

Cream was becoming a panting mess, her cheeks deep red as her eyes glazed over. "Yes, YES, DEEPER... JUST LIKE THAT. ALMOST THERE!" She cried out.

The young stallion gritted his teeth. He wanted to hold on, needed to hold on. She felt so good and the high he was chasing was putting his brain on cloud 9. Lust, pleasure and cute noises, so many things drove him to keep going. But stamina was still something he lacked at the end of the day. He felt his dick become of slopping mess as his build up the big moment came rushing up fast.

Button clenched his teeth and cried out. "Gonna cum!"

"Yes, fill me up sweetie. Cover my insides in you wonderful love!"

Button gasped as he hugged his mom tight and drove himself in as deep as he could go. "AHHH." Cream cried out as Button hissed and felt his cum unload itself deep into her core. He felt it spurt out and keep going, rinsing her insides as he hugged her tightly. Cream moaned like a creature in heat, feeling that wonderful white hot love fill her core, shootings its wonderful seed deep inside. She loved this feeling just as much as the feeling of the dick that delivered it.

Soon his potent spear stopped twitching and he slowly pulled out. Cream casually fingered herself as she let out a low sigh. "Gotta work on that stamina but I can't really talk to much, I came just as you did."

Button slowly walked around and stood in front of her, hand on his hip. "So, looks like we got quite a fun vacation to look forward to. What do you want to do now?"

Cream grinned and wrapped her arms around him. "You head on back, I'll be turning it soon, just need to do one last lap. Don't want to waste our first day sleeping through it because we had sex all night long."

Button raised an eyebrow but nodded. She let go of him, watching him turn around and swimming towards the step ladder. He slowly got out and walked out, not even bothering to grab his boxers. He simply turned and gave a thumbs up before slipping out and closing the door behind him.

Cream Heart sighed and leaned back, floating on the water. She really did love him so much. This was a truly taboo relationship but she just couldn't help herself. In any case, Button was right, its not like they were the only ones. Cream smiled as she decided to come up with some fun breakfast ideas for tomorrow as she floated in the pool, her fingers still teasing herself slightly.
