After a long day at work, Jamie (Erika's older sister) really wanted to catch up on her favourite shows but figured she'd have to kick her little sis off the tv to do so. But when she reached the living room Erika was nowhere to be seen. "I hope she didn't have another bad day at school" she said to herself, "I keep telling her if she'd just speak up more that people would realize that she's really interesting". Jamie decided to let Erika be alone for a while, if she is upset then she probably wanted to be alone for a time. Tomorrow was Saturday so Jamie figured she'd take Erika to the mall to try and cheer her up. And maybe pick up some febreeze while they're there, something is stinking up the house but she can't quite put her finger on what the smell is. Although, it was making her kinda horny.
Meanwhile Erika was slowly waking from a pleasant dream. It was crazy, this stuff was coming from her private part and it felt really good. She got it everywhere and it's stench made her feel something she couldn't describe. In fact she could almost still smell it, like it was right in front of her. She moved her arm to assist in getting up off the bed but realized it was soaked, she slowly raised her head to look down and saw her panties were drenched in some sticky stuff and stuck slimily to her waist. She looked further on and saw the far wall away from her bed looked like someone had shot a firehose at it. In an instant she sat up in her bed and said "Holy cap it's reeaaaaaAAAAHH~". As she sat up the muscles in and around her pussy had shifted causing an intense orgasm, way stronger than before. She couldn't move, the pleasure was too much and she breathed heavily to keep her brain from shutting down again. "th- thi- hiss is amA- Z- ZAANG!!!" She lasted for a solid minute before her body relented. The amount of juices that exited her body was in the gallons, forming a kind of puddle all over her bedroom floor and had started to find it's way through cracks in the floor.
Jamie was startled, she had been building up to an orgasm when she heard her sister crying all the way from her room upstairs and noticed some water leaking from the ceiling. She figured that the washing machine was had come unlatched again and made a mental note but decided that her sister was currently more important. So, feeling sisterly, she cleaned off her hand went to her sister's room to comfort her. As she climbed the stairs and heard her sister scream so she quickened her pace. But as she passed the washing machine she slowed down because she saw no sign of a leak anywhere. There wasn't even a load of laundry in it which is odd because Erika usually put her clothes in when she gets home. "AAAAHHGH~" Jamie heard another scream "I'm coming Eri, everything's gonna be okay!". Once she reached her sister's room she announced to Erika that she was coming in. Hearing no response and grunting from inside, she opened the door and took a step in but slipped and fell.
Jamie steadied her self against a semi-dry wall and wiped her now soaking hair out of her face. "Erika what the fu-!!!" She was too startled to speak, Erika hadn't even noticed that her sister had entered the room. Her fingers were desperately exploring her folds, letting girl-cum blast through her digits against the back wall. Her face was planted firmly on her completely soaked mattress literally drinking her cum out of her it. Jamie was so suprised she didn't notice that her body was getting smaller and her pussy more sensitive, it began gushing her own stream of seemingly tasty girl-cum (at least according to Erika).
