Abi got up and walked with Robin back to her office. She was no stranger to the feelings of intense arousal. In fact, it was pretty common for her and had been for almost as long as she could remember. If she could have gotten away with it she would have put her arms around Robin right then and there, but she didn't dare, Instead she walked quickly with them to her building, then into the elevator - alone. She was tempted to kiss Robin after the doors closed but she knew that the building security had a camera in the elevator so she put out her hand towards them, and then motioned up towards the camera. Finally they arrived at the 3rd floor. Abi's office was in the farthest wing of the 3rd floor. Her office was set apart from her colleagues and was actually in one of the building turrets, which gave her a wonderful panoramic view of campus. Trembling she fumbled for her keys and then opened the door and slipped inside with Robin. She closed and locked the door and turned around and faced him leaning against the door.<br/><br/>"All of this talk of threesomes..." She spoke breathlessly in a whisper. "You know what it has done to me!" She slipped her hand into her blazer and began to squeeze her breasts as she moved her other hand down over her tummy down between her legs but still overtop of her knee length skirt. "I can't help but see Xavier's big cock in your mouth as I lick you and finger myself."<br/><br/>She pulled up her skirt slightly so she could get her hand underneath her skirt. Her white cotton panties were by now soaking wet, her nipples were painfully erect and she could not stop herself from caressing her breath and pinching her nipples through her blouse and bra and rubbing herself with her other hand.
