Beth had to admit, she was slightly disappointed when Mikiri dropped to the back of the group.  Still, considering how badly the other girl's member was straining against one leg of her pants, she couldn't really blame her.  She supposed public indecency wasn't really the poor girl's thing.  That other girl who was deliberately showing off her own 12-inch cock, on the other hand...  Sensing a fellow exhibitionist, she fell in next to the girl and snuck a few glances as the tour continued.<br/><br/>There was some talk of after school activities, but that didn't really hold Beth's attention much.  She never had been one for sports, though maybe she'd be able to have some fun helping out a teacher or two.  Of course, if helping out the nurse who gave them their shots meant that she had to wear the same sort of outfit as what that incredibly voluptuous woman was wearing...  Well, she was sure she'd be helping out in the nurse's office if that was the case.<br/><br/>Not wanting to be outdone by the other exhibitionist's impressive twelve inches of length, Beth took the opportunity to adjust her outfit a little as the headmistress stepped out to use the facilities and the PE teacher was left to take over and explain their second class of the day.  She hadn't originally planned to make much of a change, really.  She'd just wanted to unbutton the first few buttons of her shirt, show off a little of her modest cleavage.  Then an idea for something a little more daring occurred to her.  Unable to resist once the impulse took hold, she reached back behind her and grabbed at the hem of her skirt in the back, pulling it up and tucking it into the waistband.<br/><br/>Now her ass was on display as well, and walking behind her wasn't going to prevent her from providing a very tempting view...
