Chapter 103

Sally caught the movement out of the corner of her eye, and noted how close the two were as Emma came forwards to try and push her under the water. She briefly thought it was curious that the two would be so comfortable being so close with Mike being naked, but the thought was lost as Emma wrapped her arms around the girl to bring her over to another part of the pool.
She turned her around and began to tickle the older girl, causing her to thrash about in her arms. She noticed Sally trying to get a hold of her swimsuit, and in truth wouldn't have cared about wearing one or not, but figured she'd better play the part of the sister that didn't want to be naked in front of her brother.
She lunged away from the older girl but felt the tips of the fingers grasping at the back of her suit, and she put her hands to her small breasts, trying to keep the suit on. Sally was relentless however, and soon all that was holding Emma's top on was the desperately grasping fingers of the youngest sister.
