He knew he shouldn't feel this way but he couldn't help it. The tingling sensation in his groin started almost as soon as he saw her out there in the garden, on her knees and bent over facing away from him. She was digging some shallow holes and pulling weeds and roots for the marigolds that she was going to plant in his garden. She was only visiting for the week but had happily went about sprucing up the place with a woman's touch.
Her skin was glistening with light perspiration as she worked in the full sun of the early-morning summer heat. Her tanned legs were tucked under her, and her short shorts were riding up enough to make any man stop and stare. The slight motions she made were not meant to be sensual but they were, and they made him feel funny and warm down there. He really should stop staring. This wasn't right and he knew it.
But he couldn't help himself. He hadn't become fully erect but he was very focused on the tingling deep inside his pelvis. His breathing was growing deep. Pulling in the air and holding it for a second while he contracted his lower abs, creating pressure. At the same time, he started to gently contract his PC muscles, one slow and gentle upwards pull at a time. Both of these sensations seemed to be putting pressure on his prostate and it felt so good.
As she rocked back and forth digging and pulling in the garden, he slowly rocked his hips back and forth with the contractions he was making, becoming fully aware of how good it felt, and how it was escalating. He put his coffee cup down and put his hands on the counter. He kept watching her from the kitchen window, thinking now about how good she might taste. He started thinking about how it would feel to part her pussy-lips with his dick and slowly slide in, feeling her tightness wrap around him. He had never looked at her this way before and couldn't explain why now of all times, that he noticed her as the woman she was.
Suddenly his heart stopped and he froze. Had she just looked back at him? Did she see his face, pleasantly contorted with the growing feelings of pleasure deep in his groin? But she wasn't looking at him now. Maybe it was paranoia. Afterall, he was in the wrong here. But he just couldn't stop with the slow upward pull of his sphincter, and the slow rhythmical rocking of his pelvis, further making his prostate feel everything.
She sat higher up on her hands and knees now, with her back arched low. Her soft heart-shaped ass was in full view. He wasn't sure if it was her sweat or what but it looked like her shorts were moist in the middle. It had to be the morning heat, because there was no way gardening was a turn-on. Well, it probably wasn't a turn-on for her but he was shamefully soaking up every bit of the view. The kitchen window was also low enough that he thought he could see up the bottom of her dangling shirt. He would love to see her tits from any angle he thought to himself. His breathing got a little faster.
He was still in his pajamas. He liked to sleep commando so his semi-hard dick hung freely but was printing pretty hard through his black shorts. He wanted to reach down and start stroking but he would never be able to hide a full hard-on if she suddenly got up and came inside. Instead, he hiked up the left leg of his shorts and let the tip of his dick hang out. The pleasure was building up and he kept contracting his abs and his PC muscles. The precum was starting to seep out and he felt like he might explode soon. He gripped the counter again.
She was using the spade in her hand to chop at a stubborn root in the garden. This caused her to rock back and forth with a little more force. He could see her tits sway from side to side a little. Each time she rocked, her ass seemed to swallow the thin bunched up fabric of her shorts between her cheeks. All he could do was imagine she was instead thrusting up against him and taking him all the way into her. Suddenly he felt like the point of no return was upon him.
He started taking deeper breaths and holding them in, helping add pressure inside his abdomen. This along with the flexing of his PC muscles and the gentle rocking of his hips really brought him to the brink. His precum started to flow instead of drip. This was it. He was about to blow a load right there in the kitchen and he hadn't even touched his dick. He thought about unloading inside of her, as wrong as it was.
He thought about how warm his cum would be, mixing with her wet pussy.
That was the last straw. He started to cum and he gripped the edge of the counter with all his might. Wave after wave of pleasure rolled though his whole body. He felt like he had been riding the edge of the point of no return forever. He could feel the thickness of his cum as it flowed out freely and hit the floor between his feet. His eyes had rolled up. He tilted his head up involuntarily as the last of the waves of orgasm flowed over him, and the cum flowed out.
He wanted to stand there for a minute and think about how he just had a true hands-free orgasm, but now he had a gob of slimy cum to clean up. He reached over for some paper towels and bent down to start wiping it up. The head of his sensitive dick rubbed against the fabric of his shorts and he felt like he might cum again right there. He focused on cleaning up the first mess before trying to make another.
He stood up, paper towel in hand and with some feelings of guilt looked out the window at her. To his immediate horror, she was not there. Suddenly the sliding door that led to back yard slid open and she walked in. She closed the door and turned towards him with a smile.
"Well good morning sunshine, how did you sleep?" She asked.
"Uh, pretty good, I think. Just woke up." He said with a nervous laugh, and added, "Spilled some coffee, I was just wiping it up."
He tossed his cum-soaked paper towel in the trash hoping she wouldn't notice, grabbed his coffee cup and headed to the small table by the window. All he could think about now was wondering if she had noticed. He wondered if she could smell the cum. He sat down, face still flush from both the most intense orgasm he has ever had, and the embarrassment that he may have been caught cuming all over the kitchen floor.
She watched him walk away seemingly flustered and she smiled. He didn't see her smile and by the time he would have been able to, she had turned towards the cupboards to grab a mug of her own. She poured her own coffee and walked over to the small table by the window and sat down with him. Her skin still damp with the morning humidity, she wiped her neck and upper chest with her hand and let out a strong exhale. She took a sip of her coffee, staring at him over the brim of the mug.
It was all he could do to not stare over at her. She was about 5' 6", toned and starting to get a nice tan. He tried hard not to think about her 34D sized tits, nestled in a bra under her light t-shirt. He tried not to think about her trim waist, her tight belly, her exposed navel, or the beautiful curve of her hips. Even though he just came what felt like a cup's worth, he started to feel his dick get a little harder.
"Thanks for starting on the garden already, but I would have helped if I knew you were getting up this early." He said to her.
"You were sleeping and looked peaceful so I decided to start early."
"Well, you look like you got a lot done already!" He smiled.
"I'm glad to be here helping." She added, "Besides, I am really glad to be here to spend time and catch up."
He couldn't stop feeling guilty about how much pleasure she just gave him and how wrong it was. He wanted to focus on something else. He tried thinking of anything to say to move the conversation on and let his thoughts about what he'd just done die out.
"So after we plant these flowers, got any plans for the day?" He asked, as nonchalant as he could.
"I'd love to find a café or somewhere to grab lunch, and really start to catch up with my brother." She smiled back at him.
There it was. He had to acknowledge he was in fact her brother and he just came, a lot, thinking about fucking her. He swallowed his sip of coffee and looked out the window to the side of the yard that overlooked a small brook. He thought about how freely the little brook was flowing and thought about how freely the cum flowed out. He just couldn't stop himself.
He stood up, walked to the sink and dumped the last of his coffee. He turned around and said, "Well, I am going to get changed and help you with the flowers, then we can get cleaned up and head out to town."
"Awesome" she said with a wry smile. "Also, might want to put on underwear. Your dick is teasing me from under your shorts." She added as she turned away and sipped her coffee.
He wasn't sure he heard her right or what to even make of that, so he turned towards the short hall and to his room. He walked past his sister's guest room and peeked in as he passed. Neat and tidy as always. They were both neat growing up and that carried over well into adult hood. Having a clean home just felt good. He supposed it also helped him right now, with feeling dirty about what had just happened to him.
He quickly put on some clothes for working in the yard, and took his sister's advice and put on some underwear, too. He took a deep breath and let it out in a sigh. He didn't technically do anything wrong he thought to himself. And as long as he never told her or acted out on it, then he'd never hurt her. While he never felt this way about her before, he did absolutely love her for their whole lives.
Growing up as fraternal twins, they were always close, but in a brother-sister twins sort of way. They had the same circle of friends in high-school and hung out often at the same places. However, after graduating, they both went off to separate colleges. She went up north to UCONN and he went to a trade-school in South Carolina. They stayed in contact with one another and occasionally saw each other at holiday gatherings, but no more than a few hours at a time, a few times a year. She had called him up and they both realized they hadn't really seen each other in a long time. The last time was at their parents' funeral.
Claire worked remotely for a software company and wanted to get out of the northeast for a while. They had talked on the phone for about an hour or so when she finally piped up and said, "Hey, what if I come down to visit for a week, would that be ok?"
Ben happily let her know that she'd be a welcome sight for his weary soul and that he could pick her up from the airport.
Benjamin had finished trade-school early and started working as an apprentice electrician. However, it was soon apparent that he was a gifted electrician, and the owner of the company promoted him to lead a team. That was short lived too, once their parents had died at the young age of 56 and 58, respectively. They had left both kids about a hundred-thousand apiece and Ben decided to us that to start his own business and was able to win some large contracts with local manufactures for performance-based support. Claire used her inheritance to pay off her student debt. This gave them both the freedom to work from home, or anywhere. It also gave Claire the chance to come down and stay with Ben for a while.
