MAIN Julie, not another boring day.

Day 30

All those mysteries running through Julies head were soon forgotten, her mom sometimes called her "absentminded". The truth was Julie thought a lot, probably a little too much. And sometime even the most interesting thoughts flew away from her when new ones took their place.

So as Julie got up for school the next day she had already let slide those thoughts of her sisters strange behavior. After all it has been a strange month, and Crissy had seemed more herself when Julie got home from school the previous day. She said that the whole bomb thing was traumatizing and that some of her memories were fuzzy, that seemed reasonable. And she was back to wearing the usual casual comfy clothes that she always had. So when she hopped into the seat next to Ashley the next morning her life almost felt like it was back to normal after the last few tense days. In fact it was better than normal, her big sis was home. She had always looked up to her older sister. Crissy was four years older and had always seemed like the smartest, prettiest, coolest girl in the world to Julie. Now that she was 18 and a little less naive she know that Crissy was just a normal young woman, but she would always be Julie's "big sis".

Classes kind of dragged, Julie had always been a good student and with graduation almost here she was just impatient to get started with her life. Seeing as the world had gone topsy-turvy high school seemed even less interesting than usual. So she was so relieved to be riding with Ashley on the way home. Imagining another fun night of chatting up her big sis. Their mom was a nurse that worked an odd schedule, with long hours for a week then a week off and she would be leaving just when Julie got home. So Julie would have Crissy all to herself tonight.

Julie was walking upstairs to ask Crissy if she wanted to do anything special when she heard some unusual noises coming from the second floor. She stuck her head in Crissy's room to see what was going on but it was empty. She looked down the hall and saw that the door to her mom's room was slightly ajar, she could see movement beyond. Then she heard noise again, this time it sounded like a bed creaking and then a soft moaning coming from the end of the hall. Julie was suddenly nervous, she had never caught her mom masterbating but assumed that she did it. As she crept down the hall the space between the door and the jam became clearer. She could see her mothers head and shoulders, she was laying in bed, rocking forward and back. She seemed to be sweating profusely, like she had been working out and was bathed in sweet.

"AWWWW BABY YES!" she suddenly moaned loudly. At this moment Julie remembered that she hadn't seen Crissy in the house. As she went down the hallway a bit more urgently now she thought, "she must be out and mom must have lost track of time." That thought was blown away as she reached the door and got a clear view of what the bedroom held.

Her mother lay in the bed completely naked, her head at one corner of the bed, she glazedly stared up at the ceiling as she came down from the orgasm she had just had. For a woman in her early 40's she was still quite attractive since she worked on her feet and stayed in shape, she had been quite a beauty two decades before. But all that was lost on Julie as she saw the firm tone body of her sister. Her head was at the opposite corner of the bed and she too was softly moaning in post orgasmic bliss. Their bodies were aligned and it seemed they had been pressed up together until just a few moments before. Now their glistening sex was about 6 inches apart but still they were connected. By this time Julie's mind was racing, it had almost gone numb. The smell of sex was so overpowering she was amazed that she hadn't sensed it sooner. The sounds and smell assaulted her mind but it was what she saw between her mother and sister that sent her mind over the edge. It was probably black but was so covered in fluids that it looked grey. It undulated with a life of it's own. Was it a dildo? One of those ones for two women? Julie had never used a sex toy but knew that there were more of them than her virgin brain could imagine. But whatever this was it didn't seem right.

Then it seemed to pull apart. One half receding into her mother and the other half into her sister. As it did they both said "I OBEY" in near unison. Crissy said it in a calm languid way, like it was the most natural thing in the would to be scissoring her mother and saying, I obey. Julie's mom sounded more confused than anything else, she was still panting heavily and her head slumped back as if she just couldn't take it anymore. Julie for her part jumped back and squeaked out "big sis" knocking the door further open in the process.

"Ah your home, good timing" Crissy said as she stood. Julie had seen her naked a few times before and was further stunned by the woman before her. Crissy had been a nice C cup but now was definitely in D territory, maybe even bigger. And her body was more toned and muscled than ever before. While mom was sweating and panting away Crissy hardly seemed to be even a little fatigued and Julie could see in her eyes that Crissy was ready for round two... with her. Crissy took a step towards Julie her right arm outstretched and beckoning Julie to come closer. "Give big sis a hug" Crissy said playfully. Just then it seemed like something black twitched between the folds of her sex.

At that moment her fight instinct surrendered and her flight instinct took over. She was down the stairs before she even knew it. She ran into the backyard and through the neighbors yard faster than she had ever run in her life. She was a mile from her house before she even looked back. Panting she ran behind a hedge and collapsed. What had just happened? Did her sister **** her mom? Seduce her? What the FUCK was that black thing? And most importantly, why was she having trouble keeping her hand from plunging into her own sex right there in public?
