She gives in

Amy decided that Rose was right and it was distracting to have to constantly fix the straps as her bestie was trying to help with getting her tutored. Amy shyly asked Rose if she minded that her training bra would just be out and Rose blushed while saying as long as it helped Amy. Rose watched Amy slide her straps off and watched her training bra come back into view. Rose continued her lesson as she watched Amy diligently take notes. Amy would lean forward occasionally and Rose could peek down and see Amy’s bare breasts freely moving about the loose cloth. Rose felt herself losing concentration when Liz reentered the room saying that the laundry was still wet and needed a little bit more. She was confused why Amy was sitting with her bra out. Amy said the straps were annoying her and getting in the way of her studying.

Liz suggested Amy just to take the dress off altogether since she was stretching it out further by having it around her waist like that. Amy had not realized that the way she was sitting on it and making it even more stretched out. Amy stood up and felt the fabric fall once as it grabbed on her diaper causing it to shift without her really noticing . Liz suggested that a trip in the dryer might help it with the over stretching and told Amy to hand it to her. Amy bent over to hand her sister the dress and flashed a bit of her pussy lip to Rose that had appeared with her diaper shifting. Rose felt herself blush as she could see a bit of her besties pussy peeking out of her diaper.

Amy asked Liz for something else to cover up but Liz said everything was in the washer at the moment so she would have to be ok with being in her underwear. Amy was disappointed but sat back down and said to Rose that hopefully her lack of a clothing didn’t get in the way. Rose knew she would be even more distracted as the cross legged Amy was flashing her pussy lip once more from the side of her diaper. Rose said it wasn’t a big deal and decided to do some math homework next.

Rose illustrated how to answer a few questions and leaned over to try to help Amy when she had questions. Her massive cleavage came into view for Amy as she was showing her how to do the formula and the constant moving around on the paper caused her tits to jiggle as well. Amy would try to follow what she saw as Rose stared at Amy’s bare chest or peeked down to see her bestie’s pussy peeking out of her diaper. The math lesson did not go well at first but after a few hours the two girls laid back on the carpet feeling absolutely exhausted. Amy rose up first to see Rose’s pussy lips completely on display as she admitted to Amy that tutoring is tough. Amy blushed and thanked her best friend for staying so late to help. Liz came back in and offered for Rose to stay the night since it was past 10pm now.
