Andy's asleep, but Amy is home...

Not long after their last fuck session, Andy fell asleep. After about an hour or so, Lily grew bored and decided to explore around the house. She shrank back down to her pixie form and made her way to the hallway. She flew up to the top of the picture frames to get a better view of the pictures hanging within.

Most were of his family over the years, along with some of Andy when he was very young. In one, she was surprised to find a photo of Andy standing proudly in his school uniform, not looking at all like his current, burly self. In it, he looked cute and innocent, and she had to giggle at the thought of him now.

As she perused the remaining photos, she came to realize something important - she knew nothing about Andy at all. She didn't know anything about his friends, his family, or anything else. All she knew was that she was now magically bonded to him forever, and they would now be spending the rest of their lives together.

Suddenly she heard a door slam, causing her to jump and hide in the shadows. A female's voice called, "I'm home!", and a young woman's face appeared beneath Lily's hiding place. It was his younger sister, Amy. She appeared to be late teen, early twenties at the most. She had a petite build, modest sized breasts, and a cute face. Her long hair was tied in a high ponytail and she wore glasses and a jacket over a plain white shirt. It was obvious that she was very shy and reserved.

Lily watched as Amy slowly made her way down the hall and disappeared into her room. She hadn't paid much attention to her earlier, being too preoccupied with her own tasks, but now she was curious about her. She'd have to keep an eye on her from now on. Maybe even have a little fun with her if the opportunity arose.

With the coast clear, Lily emerged from the shadows and flew up towards the ceiling. She was heading back towards Andy when she suddenly heard footsteps, along with the sound of a zipper being unzipped. Following the sound, she headed toward the bathroom and peeked inside. Her eyes widened as she took in the sight before her.

Amy was completely nude. She had removed her clothes and was now standing in the shower with the water cascading down her body. Lily couldn't believe it. Amy had a beautiful figure. Her smooth skin glowed under the warm water, and her breasts bounced up and down as she cleaned herself with the soap.

Lily quickly dove into the room, hiding herself under the sink, to get a better view. As she watched, Amy took the soap and began running it over her stomach and thighs. Lily couldn't tear her eyes away as she felt her own body start to heat up.

"I may be bound to Andy, but nothing says I can't have a little fun with this cutie," Lily thought as she took out her palm and blew some magical dust toward Amy. "Have fun honey," Lily snickered.

Amy's mind was lost in the euphoria of the warm water raining down on her, and the sweet aroma of the soap as it lathered her body. She was completely unaware of the tiny winged woman hiding underneath the sink, nor did she know she was about to have the best sexual experience of her life.

As Amy continued washing her body, Lily noticed her nipples were starting to become erect. Her breathing was becoming deeper and heavier. It was obvious that she was becoming aroused.

"I can't wait to play with this one," Lily thought as she blew more dust into the air.

Amy felt her body growing hotter and wetter. The water on her skin was starting to make her tingle. She rubbed her thighs together and felt the slickness between them. Her heart was racing and her pussy was starting to throb.

"What is this? I've never felt this way before," Amy thought.

She ran her hands over her breasts and squeezed her nipples. She gasped and arched her back as a jolt of pleasure shot through her body. She closed her eyes and let her head fall back. She moaned softly and continued to fondle her breasts, pinching her nipples and rubbing her thighs together.

"God, I'm so wet. I've never been this wet before," Amy thought.

Lily licked her lips. The sight of Amy fondling herself was turning her on. She could feel her own body tingling and pulsing. Her wings fluttered in anticipation.

"Time to up the ante," Lily thought as she blew another cloud of dust into the air.

Amy felt an incredible amount of lust well up inside her. She couldn't hold back any longer. She dropped to her knees, placed one hand on the tile wall for balance, and the other reached between her legs. She moaned as her fingers found her wet pussy. She rubbed it gently, gasping and moaning as she stroked herself.

She felt a tightening in her belly and knew she was getting close. She cried out and plunged her fingers deep inside her. She fucked herself as hard and fast as she could, her mind a frenzy of arousal.

"It's time, honey," Lily thought as she grinned wickedly.

Amy's body stiffened as her orgasm crashed through her. Wave after wave of pleasure washed over her, causing her to cry out in ecstasy. Her eyes rolled back into her head and her mind went blank, her body going numb. She fell onto her side, curled into a ball, her fingers still inside her pussy, her juices dripping out of her.

As the sensation of her orgasm started to subside, she slowly regained her senses. When she tried to pull her hand away, however, it wouldn't budge. Instead it started acting on its own and began finger fucking her swollen pussy.

"What the?" Amy shouted in confusion as her other hand clutched her bouncing tit.

Amy writhed and squirmed, trying to fight off the strange sensations coursing through her body. She screamed and moaned and groaned as her fingers drove deeper and deeper into her.

"What's happening? Why can't I control my hands?" Amy began to panic.

Lily couldn't contain her glee. She watched gleefully as Amy thrashed about, helpless against her own hands.

"This is going even better than I had hoped," Lily mused, licking her lips as she began masturbating to the sight before her.

Amy struggled and fought, but her hands would not relent. They continued to rub and touch and stroke her, bringing her closer and closer to another climax.

"Stop...stop..." Amy begged, but her hands paid her no mind.

She arched her back and screamed as the next orgasm ripped through her body. It was even more intense than the first, sending shockwaves of pleasure throughout her.

"Oh god, oh god, oh god," Amy chanted as her body continued to convulse.

She writhed and squirmed, trying desperately to resist her hands, but her efforts were futile. She lay there on her back, helpless, as her fingers pleasured her.

"Why can't I stop?" Amy wondered, terrified. "Oh god!"

Lily watched with a huge grin on her face. She was enjoying this immensely. To see such a timid and shy girl have her mind and body dominated by her own hands was incredibly hot.

"This is too much fun," Lily thought.

Amy felt tears streaming down her face as her body betrayed her again. She screamed and bucked her hips, as her fingers stretched her and filled her up, pushing deeper and deeper inside her.

"Make it stop," Amy begged.

She clenched her eyes shut and tried to fight her hands, but they were relentless. She lay there, powerless, as her fingers violated her.

"Oh, fuck. Please..." Amy cried.

As the waves of pleasure washed over her, her mind became foggy and fuzzy. Her thoughts were consumed by the sensations pulsating through her.

"Please, please, please," Amy begged, but her hands paid her no heed.

They continued to drive her crazy, making her buck and writhe and scream.

"Oh god, oh god, oh god," Amy whimpered.

Lily's grin grew even wider. She loved watching the poor girl struggle. Her own climax was close but she wanted more. She licked her lips and blew another dust cloud toward her.

"Let's kick it up a notch," Lily thought.

Amy shrieked as her body spasmed and convulsed. Her hands were moving faster and harder now, driving into her. She could feel her pussy stretching and expanding, her fingers filling her up and driving deeper and deeper.

"Please, stop, please," Amy begged, but her hands ignored her. Suddenly, her clit and nipples began to vibrate.

"OH MY GOD!" Amy screamed, her body contorting.

She writhed and twisted, bucking her hips and arching her back, trying to escape the sensations surging through her. But it was impossible. She was a prisoner in her own body, a prisoner to her own mind. Her orgasm exploded through her, the most powerful yet. Her juices gushed forth, covering her hands.

"So fucking perfect," Lily purred as her climax caused her to orgasm right alongside her new toy.

As the last waves of her orgasm subsided, she felt her hands pull out of her, the buzzing stop, and a brief sensation of soreness in her crotch. She collapsed and lay on her back, completely exhausted.

As she struggled to regain her senses, Lily walked to her face and gently kissed her forehead. She giggled as Amy tried to turn away.

"Sleep now honey, you'll need your strength," Lily whispered as her magic sedated her.

Satisfied and spent, Lily made her way back to her bed and rested until Andy awoke the next morning.

The following morning, Andy got up early to prepare breakfast. When he got downstairs, his sister Amy was sitting at the counter.

"Hey Sis, how did you sleep?" he said as he hugged her from behind.

She gave a smile, and then turned back to her breakfast, taking another spoonful of cereal and then munching it quietly.

Andy could sense something was off with her. "Sis? You okay?" he asked again.

Amy continued to ignore him, staring straight ahead and chewing slowly. He shrugged it off as just a bad case of morning grogginess and decided to start making some breakfast of his own. As he cooked, Amy got up from her stool and walked to the living room couch and laid down. He turned back to see Amy was just staring up at the ceiling with an absent expression on her face, her eyes wide and glassy.

"Amy? You're really acting odd, are you sick?" He said, trying to get her attention, but Amy just lay there unmoving and unresponsive. Andy sighed and shrugged again, then headed back to the stove. As he prepared to turn the eggs in the frying pan, something landed on his shoulder, causing him to jump in surprise.

"Fuck," he muttered. It was Lily. She was looking up at him, smiling mischievously. "Jesus, Lily, you scared the crap out of me!" he said, irritated.

She smiled even more, obviously very proud of her accomplishment, but before he could ask her what was going on, Amy walked past them both. Andy watched in stunned disbelief as Amy went to her room without saying a word. He was starting to get seriously worried.

"Lily, did you see how Amy is acting?" he asked Lily, concerned.

She laughed and gave him a peck on the cheek before saying, "She's fine. I think she had a little too much fun with my magic last night."

Andy looked at her, puzzled. "Fun? With your magic? What did you do to her?" he questioned.

Lily put on a pouting expression, pretending to be offended. "I just had some fun with her, that's all."

"What? What did you do?" He questioned.

Lily just grinned, then flew off to Andy's bedroom, giggling as she left him with his questions unanswered.
