Found!

Felicia's moan's were loud and constant now. Both sisters lay in silence, their hearts racing with the fear that they would be found any moment. Lisa half expected the frat brothers in the doorway would hear her heart beating and discover them but Felicia was doing a good job of making sure nothing was heart. The springs creaked above them and there was an obscene slapping sound suggesting the 'Monster' was giving Felicia the ride of her life. Lisa heard the sound of a phone camera taking a few pictures from the door then after a bit of laughing the door swung mostly closed and the watching frat brothers moved on.
She would never admit it but part of her was disappointed. Lisa had always been very concerned with her image and didn't like letting others take control of anything but something about the events of the last few days had made her curious, and a part of her which she would never give in to, wanted to know what it would feel like to be taken, her own desires ignored and made into one of these frat idiots fuck-babe. She groaned inwardly at the thought, simultaneously repulsed and excited.

She mentally shook herself, pulling herself out of that train of thought. She was sure she didn't want to another cheap victory for DKM, no matter what it would feel like, and as she thought about it the idea of one of these pig's conquering her was repulsive. Still, she had to admit the train of thought (perhaps aided by the loud moans coming from her sister) were having an effect on her. Ignoring her arousal, she turned to look at Sarah. Her eyes were closed so she leant over to whisper in her ear. Unfortunately as she shifted closer she moved under the center of the bed. She was about to suggest trying to get the pennant again when a particularly heavy thrust, accompanied by an extra loud moan from Felicia, **** the mattress to sag low, hitting Lisa in the side of the face. She let out a yelp of surprise. Sarah's eyes shot open and she looked at Lisa in horror.
