Muss and Sara were ready for breakfast after their explorations of the morning. Muss drew his shorts up and Sara wrapped her robe back around her. Once in the kitchen, Muss grabbed a bag of cereal and filled a couple of bowls. His unease at what he and his sister were doing was beginning to return. 
However, as he ate his thoughts kept returning to the way her butt felt rubbing his sensitive cock or the way her mouth felt gliding over its head. He was unsure he should continue to mess with his sister that way, but his traitorous appendage was already yearning to feel the caress of her hand, butt, or mouth. 
Muss shoveled his cereal as fast as he could. Then, excusing himself he went to the bathroom to take a shower and think without Sara sitting right there to cloud his mind. However, once in the shower all he could picture was the gray of the movie with her hands working over first her pussy then her mates cock. 
Meanwhile, Sara was thoroughly enjoying the glow brought on by the ministrations of her brother and her hands. Her pussy continued to give off a low-level pulse of pleasure, and her mind returned to the scene she had witnessed, as well. She kept seeing the way the silver’s cock had slipped so easily into the gray, and she remembered the way just putting a finger into that hole in her body had lit a fire in her abdomen. 
Thinking of the scene and the feelings invoked a sudden desire to feel them again and she spread her legs and started to rub the lips of her most private area. As her fingers slid over the sensitive skin of her forming womanhood, she could feel the rekindling of the fire she knew would come. She thought back to the way it first felt when Muss placed his hand were she was now rubbing, and the sparks grew even stronger. She imagined Muss walking in and taking her small and nubile breasts into his hands, and let her other hand act that part out for him. Her breath started to come in quick gasps as her hands worked her body. The middle finger of the hand on her pussy slid between the smooth lips of her sex, eliciting a gasp at the growing fire in her belly. In her mind, Muss had placed his mouth over her tit and was pulling the other tit with his inexperienced yet capable fingers. Her middle finger was now working furiously over her responsive clit and her pleasure juices were running freely.
The fire she had stroked to life was now a raging furnace of pleasure, and she remembered the cock entering the gray. So, despite the need she had created in her body, she stopped and moved quickly to the refrigerator. Her finger continued to work over her pussy as she looked around until she found what she was looking for. She pulled the carrot out of the fridge and returned to her chair. 
Sara worked her pussy a while longer, returning it to the burning need she had halted to find the carrot. Once she returned to that feeling, she grabbed the carrot and ran it up and down her slit; the cold of the carrot contrasting shockingly to the furnace that was roaring inside her. She continued rubbing the vegetable up and down the entire length of her now raging pussy unconsciously allowing it to be well lubricated. Deciding she could wait no longer she turned the carrot lined it up and slid the tip into the hole of her pussy.
Just as she was placing the carrot to her sex, Muss walked through the door. The argument he had devised to halt further encounters with his sister died on his lips. The shock of what he was watching froze him in his tracks and his ever-ready cock defiantly stood to attention.
With a moan of pleasure, Sara slid the carrot slowly, ever so slowly into her body, allowing her body to get use to the stretching that was taking place. She stopped when the carrot was in about a quarter of the way and once again started vigorously rubbing her clit as her pussy adjusted to the intrusion she had initiated. It did not take long before she was moaning in pleasure. 
All this time Sara had her eyes shut, envisioning the carrot as her brother’s cock, and with her eyes closed, she was unaware of the fact that Muss was stroking that very appendage and raptly watching as she moved the carrot. She briefly pulled on the carrot feeling its rough texture slide out. Then she slid it back pushing it just a bit further than the first time. Once again, she was unable to stifle her groan of pleasure. Continuing, she moved it faster and pushed it further with each stroke. Her hips began to move on their own accord and she emitted a gasp or moan of pure bliss with each thrust of the carrot.
Muss was far too excited know what he was doing. Indeed, he did not even realize he had moved until his hand grabbed the carrot and pulled it from Sara’s hand and pussy. Sara reaction was a mix between a gasp of surprise and a groan of disappointment she had been so close. However, when she saw Muss’ erect cock lined up to take the carrot’s place, she huskily moaned out, “Please take my pussy with your cock; I need to feel you inside.”
Muss immediately rammed his hard member into Sara’s open, receptive, and well-lubed pussy, and was promptly rewarded with her scream of pleasure as her whole body convulsed in the largest orgasm she had yet encountered. The site, sound, and feel of that massive orgasm put Muss over the edge and before he could take his cock from her body, he unleashed a torrent of cum into her well-used pleasure hole.
For a brief time after the two had their first brief but explosive experience with intercourse, Muss and Sara did not even move as they basked in the glow of what they had just done. Both knew that they would never be able go back, but neither much cared. As Muss felt his cock slacken and slide out of his sister, he could only think of how good it felt to be inside her. It was better than anything they had previously done before. He now understood why the silver on screen had been willing to remove his cock from the gray’s mouth. Sara for all that she had enjoyed having the carrot inside her knew that she would take the stretching she received from her brother’s cock over the carrot any day. Both knew that this was only the beginning of a very pleasant relationship.
