He doesn't, someone else does

Janet had been steamrolling her test and was basically finished with her midterm when she heard a gasp from next to her. Looking in that direction, she recognized Mackenzie from her previous escapade but was very surprised to notice the alluring redhead was a little... underdressed, for the class. She watched in amusement between questions as she saw Zack push down her pants, steal them and finish unraveling Mackenzie's shirt. She noticed him placing the items in his bag. She always had a crush on Zack, and felt a little jealous at the attention Mackenzie was getting. On the other hand, Janet liked being first at everything. She was attractive herself, but had found herself less the center of attention since Mackenzie's earlier incidents.

She had been infuriated at hearing for weeks about the "hot redhead streaker" who was "beautiful beyond words". No one shows up Janet at this university! She thought to herself. She had swore that she would get Mackenzie back if the opportunity ever presented itself. Well, well, well.. Two birds... She thoughtfully mused to herself. Noting that Zack had ceased his ****, she came up with a plan. She tore off a small slip of her exam's blue book. Usually the spare page is detachable and disposable when its not used. (Janet had been quick and to the point, so she had extra.) So she wrote a little note and waited a moment for the professors watchful eyes to pass over again. As he focused on his desk, she tossed the note over to Mackenzie's desk.

Mackenzie was still sitting with her arms crossed as the note landed on her desk from the side. She looked over and saw a girl smiling at her. I know her... I think. Her name starts with a J right? Mackenzie thought to herself. Cautiously holding the bra with one forearm, she reached out to grab the note and read it.

'Hey, looks like you're in a bit of a tight spot. If you give me your bra, I'll give you my dress. I have shorts on underneath but I don't have a bra myself, nod if you agree.' Mackenzie looked Janet over again. The girl was in a cute sundress made of thin cotton. It looked a little frail, but it certainly would beat being naked. Mackenzie nodded once subtly, looking nervously towards the front.

A second note dropped onto her desk.
'Alright. Hand over your bra with the notes and I'll give you my dress.' the second note read.
Mackenzie hesitated for a moment, thinking. Surely a dress with nothing underneath is better than just a bra. She convinced herself, rationalizing that she didn't really have any other options anyways. She nervously took a deep breath before slipping the bra off beneath her arms, trying hard not to expose her boobs to the rest of the class... again. Covering herself with one hand, she waited and then tossed the bra and notes back onto Janet's desk, before bringing her arm back to cover herself again.

Janet, for her part, was shocked. To be honest, she didn't think it was going to work. She figured the girl would be suspicious. She figured it must be true what they say about maxing charisma at the detriment to other stats. This girl is beautiful but she is dumbbbb, lol. She chuckled internally at her nerdiness, thinking her DnD night halfling rogue would be so proud right now. +1 RP rating, **** and a cute bra! She thought connivingly.
