Spencer glared at Prentiss as she left for the evening. She had wanted to finish the geographical profile before she called it a night. Now it was just Spencer and the map left. He stalked up to it, he knew it wasn't its fault but the jealously burned within him.
Prentiss hadn't been asked to do the profile, Spencer had been out with Rossi interviewing a witness and she had nothing else to do. She did a perfectly fine job but coming back to the station to find her hands running over the map, to find her leaning over it breathing on it, whispering to it. Spencer just seethed. The map was his, and now it was tainted.
Spencer stood in front of the map, his anger had turned to sadness that this map would never be his. He pulled out the first map he ever loved, a map of Middle Earth, from his satchel. He always carried it with him as a reminder of those simpler times and of the rush of discovery. He lay it on the ground and after undressing he pulled Prentiss' map off the board and together they lay on the map on the ground.
Rolling Prentiss' map up he covered it in lube replaced the anal plug inside him with it, also something he always had in his satchel. The plug he had put in earlier that day when he first saw Prentiss and the map.
Turning over so that his front was lying on the map Spencer began to redo the geographical profile on a new map. Slowly rubbing himself against the map on the floor. Once he was done Spencer proceeded to lick the new map while fucking himself on the old one. When he felt himself about to come he pulled the map out and shot himself all over it.
After redressing and putting his map up on the board Spencer sneaked into Prentiss' room and left her now stained map on the pillow next to where she was sleeping. When she awoke she'd learn that maps were Spencer's.
