Kattie stood in the forest looking down at the knew appendage that the goddess had given her, and was thinking what she could do with it. "If you are not sure what you want to do you can alway just test it out" said Ruby in her head. "How do I do that. I have only seen a boy's parts once before on accident when my dad was getting out of the shower." Replied Kattie. " its easy you will want to remove those ruined underwear you wearing and lift your skirt higher before you start". After Kattie complied with Ruby's directions she was told to grab hold of shaft and slowly rub up and down. When Kattie grabbed hold she felt a slight shock at how sensitive this new part of her body was. After a few seconds of rubbing she felt a surging of blood into her penis and an increase in pleasure coming from it. "Is it supposed to be getting bigger" said Kattie as her member was reaching 8 inches in length. "This is normal and it will start getting very hard when it reaches its final length" answered Ruby. Kattie was subconsciously increasing the speed that she was rubbing herself that when she reached her max length of 10 inches she had an almost frantic pace. The pleasure that she was feeling was going to her mind and blocking everything out but her and her pleasure. Then there was a tightness coming from right underneath her shaft and she felt her balls rise up and hug the bottom of her dick. She then ejaculated sending globs of white fluid in a streak in front of her.
The sudden intense sensation of her first orgasm left her slightly dazed and she sat on the ground. "That was great for a test run" said Ruby into Kattie's mind. "That was so good I can't wait to do it again" said Kattie. "You know you can feel even better if you do it with someone else" replied Ruby. Kattie was thinking about who else she could do it with when she remembered why she was out in the forest in the first place. "I want to but Jake won't stop teasing me so I don't want to go back home to find someone else". "Why don't we just do it with Jake". Suggested Rudy. "But how he would just laugh at me". "Don't worry leave that to me".
20 minutes later after Kattie had walked out of the woods back to her house and up the stairs she found her self outside of her brother Jake's room. Jake being 4 years older than her at 12 years old could be heard for the out side of his room playing a noisy video game. "So I just walk in there and touch him on the neck" asked Kattie to Ruby. "Yes and after that the fun begins". Before she gets too scared she opens the door and walks in. Jake was sitting in the middle of his room facing away form the door. He was turning around to see who just entered when he saw his sister walk up and touch his neck. He immediately froze up and was unable to say anything."It worked. Now what" said Kattie. "Ask him to stand up and remove his pants and underwear" said Ruby. After receiving those direction from his sister Jake as if in a trance stood up and removed all of the clothes from his lower body. "Now ask him to bend over onto the bed" continued Ruby. Moments later Kattie was looking a her brothers butt and tiny asshole. "We should prepare him before you have you fun. Start by rubbing his checks. Kattie grabbed each check and stared to massage them. Jake unconsciously released a moan as his rear was being assaulted. After a minute of this Jakes butt started to expand a little had his hips widen. Another minute later Kattie looked at his asshole to find that it looked light a little puffy donut hole. "He's ready" said Ruby in a luscious tone. Kattie by now was fully erect and needed no further prompting. She lined up her cock with his rear entrance and pushed forward. Her cock seemed to release precum the second she made contact and allowed her to enter Jake's anus on her first thrust. He released another long moan at this point as he felt the first 5 inches enter him. On instinct Kattie began her humping to get the rest of her self into him. After several thrusts getting her up 8 inches deep she pulled back leaving just her head in him. She then gave a mighty thrust bottoming out with all 10 inches in him. The pleasure that she was feeling was intense and she wanted more. She continued to thrust in and out picking up speed slowly, as she groped around his body and found his erect cock. To her estimate it was quite a bit smaller than her's. She started to rub his like she had done to her cock back in the forest. Only a matter of seconds later did she feel a wetness on the hand that was rubbing his cock. "He seems to be quite the quick shot. What a waste, I should just give some of that length to someone who can use it" said Ruby. Kattie then felt an increase in the resistance to her thrusts and a srinking of her brother's cock. The resistance increased until she could not take it anymore and she released her girl cum into her brother's ass. After a solid minute of her pumping his stomach full she finally pulled her self out of him to see her now 14 inch cock. "That was great where to next" said Ruby
