"Me?" Christie said, trying to hide her shock and not doing a very good job of it.
"I couldn't figure out how it responded to what I was feeling," Andi said, "Then I realized that any phone nearby could connect to it."
Christie sat and said nothing, she was terrified at that moment.
"It was amazing Aunt Christie, Andi said softly, "I've never had an orgasm like that in my life. Thank you."
Christie exhaled, then looked at Andi and saw a look in her eyes that made her melt. She explained how she had seen the notification and ended up outside her door. "Listening to you got me so turned on, I went back to my room and had an amazing orgasm of my own."
Andi smiled; she was so turned on right now. "I know what you mean, after I saw you cum, I went back to my room and fingered myself," she said in a whisper.
"Saw me?" Christie asked, surprised.
"Yes," Andi responded, "Your door was cracked, and I was going downstairs. I stopped when I heard you, then watched you through the crack in the door. I also listened to you another night, but I figure you knew that."
"Well, I suspected it," Christie answered, "I wasn't sure. When I imagined you out there listening to me, I made myself cum again."
They sat quietly for a moment, not sure what to do next. "Aunt Christie?" Andi said, somehow, it felt more exciting when she called her Aunt Christie again, "Would you do it again?"
"Do what again?" Christie asked, unsure what she was asking.
"Control my toy and make me cum like that again," Andi whispered.
Christie sat in stunned silence for a moment. This is what she had been fantasizing about, what she had wanted, at least when it was nothing but an unrealistic fantasy, like Chloe. This was one of those things in life you can't take back, so they both had to understand what it meant and what it could mean. "Andi, I'd love nothing more," she said quietly, "but we need to talk about what this all means before we go any further, and this is not the place for that conversation."
Andi nodded, she knew this was a big deal, not just that it was her aunt, but that they were living together, and it was going to change everything about their relationship going forward. "I know," she said with a soft smile, "let's go back to the house."
They scooped up their belongings and walked back to the house in silence, idle chit chat seemed very out of place at the moment. They set their stuff down and went and sat in the family room on the couch.
Christie leaned in and placed her hand on top of Andi's and said, "First, the thought of this makes me so excited. I have been fantasizing about you since the night you arrived, and I saw what a beautiful woman you have become. But this is something we can't undo, a line that once we cross, we can't go back. It could destroy our relationship if things go bad."
"I know, I've been thinking about it all weekend, since we talked on Friday night," Andi answered, squeezing Christie's hand. "I feel like we've already crossed that line though."
Christie nodded and softly, "Yeah, I kind of did."
"No," Andi said, "We did. Me outside your room watching you, playing with myself was the same."
"OK," Christie said with a smile, it was probably not a time to debate the relative aspects of who is more of a pervert than the other. "And you understand, no one can know about this. I can't even tell Maddi, who I tell pretty much everything, no matter how twisted."
"Is this twisted?" Andi asked.
Christie started to just say no, but she had to admit in some ways it was. If it was something they had to hide from the world, it probably could be considered twisted. "I guess in some ways it is, to be honest," she said.
"Yeah," Andi replied. "It kind of is. But it doesn't feel wrong to me."
Seemed like they had made a decision. "Andi, if it feels wrong or weird or you have any doubts at any time, we stop and we never speak of it again, OK?" she said.
Andi nodded and stood, holding Christie's hand. They walked up the stairs and down the hall to Andi's room. They were both still wearing their bikinis and cotton coverups as they went into the room and Christie closed the door behind her.
"How about I sit over here?' Christie said, pointing to the small armchair in the corner of the room.
Andi nodded as she opened the drawer in the nightstand and pulled the toy out. She turned it on and heard the chime on Christie's phone which made her giggle. "Guess you're always going to know when I'm using this," she said.
"I'll turn the notification off," Christie said.
"No, don't," Andi replied with a grin.
Christie pressed the indicator to pair her phone with the toy and the power button changed from flashing blue to solid blue. Christie sat back and unbuttoned her cover up, letting it fall open.
Andi set the toy down on the bed and took off her coverup, then untied her bikini top, letting it fall to the floor. She stacked the pillows on the bed and slid up onto the bed facing Christie, just wearing her bikini bottoms. "Have you ever done this before?" Andi asked. "I'm not sure what to do."
"Not in person," Christie answered. "Just do what you would normally do, and we'll go with it."
Andi nodded and held out her hand, spitting in it and rubbing the saliva over the tip of the toy. She moved the toy to her nipple, her eyes on Christie the whole time.
Christie started the main arm vibration, very low at first then increased it slightly as Andi moved the toy slowly over her swelling nipple. Christie's free hand reached down and pushed her bikini top down, exposing her breasts as she watched.
Andi moaned softly as Christie increased the vibration level, Andi's hand sliding down her belly and over her mound, pushing the bikini bottom to the side and exposing her pussy. Her lips were glistening as she had been wet since the conversation first started down at the pool. Andi slipped a finger inside her pussy, slowing gliding it deep then pulling it out and moving it to her lips where she playfully sucked it while looking at Christie.
Christie's hand slid down her body and her legs spread, when her fingers reached her pussy, she began to rub it softly. She watched as Andi set the toy on the bed and slid her bikini bottom off.
She picked up the toy and moved it between her legs, setting the vibrating tip against the opening of her pussy and slowly pushing it in. She moaned and her hips lifted from the bed as the toy penetrated her slowly. Once the toy was fully inserted, Christie began the rotation of the main arm, alternating the intensity up and down, then turning on the vibration of the small arm that was pressing against Andi's clit.
Christie continued to alternate the power of the three actuators, watching and hearing Andi react, her fingers plunging deep inside her own pussy as she did. Andi began to squirm, and Christie stopped the toy suddenly cause Andi to exhale sharply and say, "Oh fuck, not again, please don't stop."
She started the toy up again, slowly increasing the intensity and listening to Andi squeal with delight and pant as she said, "Fuck yes, that's it, fuck, fuck, Aunt Christie."
Christie was close to cuming, but she held back as she watched Andi squirm. She couldn't hold it off any longer, so she dropped the power on the toy to a slow rumble and finished herself off as Andi watched and pleaded with her not to stop.
She smiled and rubbed her dripping pussy as she eased the power up on the toy again. Her fingers slipped back inside her pussy, and she began fucking herself again. Christie brought Andi close to orgasm five or six more times and made herself cum again as Andi's pleas became more urgent.
Once again, Andi felt the power levels of the toy increase as she panted and thrashed on the bed as she neared climax again. She felt the power begin to drop again and begged, "No, no, no, no, no. Please, Please. Not again." This time, Christie pushed the power back up and Andi felt a nearly instant surge as her body let loose and she was pushed over the edge.
Christie smiled as she watched Andi's body shudder and stiffen, her hips driving up as her back arched. She eased the power of the toy down until it was off, then sat and watched as Andi settled back down onto the bed, whimpering softly and easing the toy from her pussy.
Christie disconnected the toy from her phone and stood, walking across the room. Andi lay on the bed, panting and still shaking softly. Christie ran her fingers through Andi's hair and leaned down and kissed her forehead. "You are amazing, Andi," she whispered.
Andi's hand ran up Christie's arm and she smiled, "I've never felt anything like that."
"I'm going to go make us something to eat, sweetie," Christie said, then turned and left the room. On her way downstairs, she changed into shorts and a T-shirt.
Andi lay there for a few minutes, basking in the afterglow. She got up and went into the bathroom and cleaned herself up, then dressed in her sleep shirt and a pair of cotton panties. She grabbed her phone and opened the shopping app, ordering another of the toys and paying the couple extra dollars to have it delivered to the locker the next day. Smiling, she went downstairs and helped Christie make dinner.
They ate dinner, then went into the family room to relax. They sat together on the couch, holding hands and leaning against each other. When it was time to go to bed, they went upstairs and said goodnight, then went to their rooms and quickly fell asleep.
As she walked down the stairs in the morning, Christie wondered if there was going to be a feeling of awkwardness between them after what they had done the day before. She didn't feel it at all when she saw Andi and if Andi felt it, she didn't show any signs. Andi's face lit up when she saw her, and she gave her a quick kiss on the cheek as she headed out the door for the gym.
