Mary chickens out.

No this has already gone too far. Mary mentally chided herself. Sexually assaulting my best friend is not how I planned on starting my vacation. With that decided Mary closed her friends top.

Ugh, I still need to cover her lower half. I can't have her brother peeking back here and seeing his sister half naked asleep in my lap. Mary thought as she searched for something to cover her friend up. Finally, she spied a blanket on the floor board. That'll do. Mary decided as she leaned forward to retrieve the covering. As she did, she felt Susan's nose brush against one of her breasts. Mary was just barely able to keep her composure at the unexpected stimuli she did, however, look up as she as a small jolt of pleasure went through her body. Wait, was John sneaking a peak. Mary froze in terror at the prospect. She stared at the back of John's head for what seemed like an eternity before she was satisfied that her mind was playing tricks on her. Finally, she picked up the blanket and covered Susan. Her nerves frayed Mary drifted off into a dreamless slumber.
