Sarah was absolutely amazed by how perfect her figure was, she began to get jeoulous and wish she had her body as well. She continued to watch her until she appeared to go to sleep. She took this as her chance to come out of her hiding spot and come closer towards the girl. Once she got close enough, she got the sudden urge to touch and grope her plump ass. She figured she was fully asleep and didn't think it would hurt to try, just one touch. She slowly reached her hand forward and closed her eyes. Once she finally touched it, she gasped at the pure softness of her rump and wanted to feel it some more. But she decided to wait to she if the girl would react.
