Just Say 'Yes'

Two young k**s. A brother and a sister playing with their friends from down the block. Up in the tree house the four of them giggled as one showed his penis to the others.
"Your turn."
One by one they all dropped their underwear exposing what they had. The two boys were very hard. Each girl felt one of the boys' penises. The boys got to touch the girls' pussies but no penetration. All were bare and hairless. It seemed so much fun to get naughty that way.
Fast forward three years. Jack's sister Terri had grown pubic hair and was in the middle of changing into a woman. Her hormones raged within. There was an opportunity with her brother. A night at Grandma's and Grandpa's house. The two had to share a queen-sized bed. In that bedroom Terri reached over to touch her brother. Her hormones drove her to be bad. Her hand felt her brother's penis. It instantly became rock hard. She whispered to him. "Take off your clothes." They stripped and quietly she guided her brother between her legs. Jack felt his siter's pussy. He discovered she had grown hair down there. She let him look at her new pussy. He rubbed it with his hand. Then she had him grind into her. His little boy dick could not quite penetrate very much at all. They continued grinding until they both became tired, and they put their clothes back on and fell asleep. The next day it was as though it never happened.

The road stretched out long. Four hours of driving took him to his sister's place in Napierville. He pulled into her driveway and shut off the truck. A sigh of relief came over him. He sat there recalling that time they grinded together. Now that her long-time boyfriend Tom had passed, he knew she would be lonely possibly in a way he might serve her. The last visit he had heard her and Tom making the bedposts hit the wall as they obviously enjoyed making love. He knew she would be missing that. He also knew he could take Tom's place if she had any desire for it. He got out of the truck and headed inside. There they met. "Hi!"
"Hi!" They hugged. Jack noticed immediately that his sister was braless. "We can't golf tonight."
"What?"
"They had to close the course for repairs to the water system. They had a huge water main break, so we're stuck here tonight.
"Oh. Okay."
"I thought we'd order a pizza. Is that okay?"
"Sure."
Her nipples were very hard poking her tee shirt.
"So, how have you been?"
"Lonely. But I get by."
"You miss Tom."
"Yes, I do. In many ways."
"I'm sure you do."
"How is Jo?"
"She's fine."
"What's wrong? That came out kind of sour."
"We're not getting along so great."
"Oh? What's wrong?"
"Seems she isn't in the mood anymore."
"Oh! That sucks!"
"She even told me she would be just as happy going without from now on."
"HHHHHHHHHMMMMMMMM! I need a drink. You want a beer?"
"Absolutely."
"After I make this drink, I want to go change into something more comfortable since we're not going anywhere. Then you can tell me all about it."
Terri reached into her fridge to get a beer. Her tight jeans outlined her curves as her brother looked at her. He knew something was brewing between them. She handed him the beer with a smile. Then she began to make her martini. "Why don't you come up with me and talk?"
"Okay."
Up in her bedroom Terri took off her jeans.
"You know, I never knew how much I would miss just having someone to fuck with."
"I bet." Jack could see her pubic hair spilling out from her panties. She dug into her dresser trying to find a pair of comfy sweatpants.
"Damn it. I think they're in the laundry. Oh well."
"Remember when we were at Grandma's and shared a bed together?"
"I do. We were bad that night. Funny you should bring that up."
"I know. Would you like to try that again?"
"Right now?"
Jack began to undress. Terri froze, lost in deep thought as she watched her brother undress. She let him take everything off and his cock looked so hard and thick. "Wow!"
"Let's fuck!"
"Somehow I knew we would."
"I knew it too! I think we were meant to be together that way!"
Jack moved close to her and slid his hand inside his sister's panties as she gently held his hard cock. Her pussy was soaking wet. Jack put his lips on hers and her lips opened as their tongues swirled together. Both began to breath much heavier. Jack's cock was throbbing hard. The kiss ended. Jack knelt down pulling his sister's panties down exposing her big fluffy black bush. He pushed his face into her muff extending his tongue into her nether flesh tasting her pussy.
"Oh God!"
"MMMMMMMMMMMMMMMM! I just love sweet pussy!"
He began to lick her as she widened her stance giving him better access. "I can't believe we're doing this!"
"I can! I love i****t! I want to fuck my sister and come in her pussy!"
"Yes! Take me!" They moved to the bed. Terri laid back and spread wide open. Jack moved in and began licking her pussy. He licked and teased driving her crazy with his tongue. For five minutes he worked her into a lather. Then he sucked her clit into his mouth and began flicking it causing her to scream out in passion. "OOOOOOOOOOOOOOOOOOOOHHHHHHHHHHHHHHHHHHHH!!!"
Suddenly pussy juice came squirting out of her pussy splashing her brother's face. The sound was unmistakable. Jack quickly moved up. Her pussy juice dripped from his face onto her naked body. Their eyes met as his cock slid inside his sister's wet pussy. "Fuck me!"
"Yes! Finally, I get to fuck my sister!"
It was so surreal. They both wanted it so badly. The passion ran very high as Jack began to move slowly in and out of her. They kissed passionately as their bodies adapted to one another. They pawed at each other touching in ways they had only imagined they would have before. Now it was real. They were connecting the way they knew they could if given the right circumstance which had just presented itself. Now it was game on, and they were determined to complete the transaction.
"I want you to come inside me!"
"I will. But I want to make this last and make it count!"
"Take your time baby! MMMMMMMMMMMMMMMMMM, you feel so good inside me!"
"Your pussy is so hot!"
"Hot for your cock! It's been months! You wouldn't believe how horny I am right now! I needed this so badly!"
"We have all weekend. I'll give you all you want!"
"We can come straight home tomorrow and start fucking!"
"Yes!"
Jack raised up on his arms. He began to thrust deep and hard while his sister rubbed his chest. Their bodies slapped together furiously as Jack began to holler out. "YES! SHOOT IT IN ME! FUCK ME! FUCK YOUR SISTER JACKIE!"
"AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHH!" Jack began to pump twelve big shots of come into his siter's gushing pussy. She could feel his power as her pussy began to convulse with a delightful orgasm. Jack slowed down to a stop and they began kissing again. He stayed deep inside her satisfied and happy. She held onto him caressing his buttocks. They just laid there catching their breath feeling each other's bodies touching in such a forbidden way. The deed was done, and they enjoyed every dirty touch. "Mom would be so proud."
They both laughed. "I kind of wish she was here watching."
"Well, it was fun watching you do me."
"I loved every second of what we just did."
"I think we could have a lot of fun together."
"I know we could."
"I'm glad it finally happened."
"Me too."
The rest of that weekend was filled with plenty of golf and even more hardcore fucking. They made a pact that they would get together one weekend a month and go at it like a****ls. From then on it was understood. They were secret lovers. No one else could ever imagine how hot and intense that kind of love really is. There was something very hot about taboo love.
