Sexual Feelings Towards A Co-worker

One of my co-worker(29 F) she is married and has a baby. She is driving me crazy, whenever i see her, i imagine doing sexy acts in office with her. Her lips, ass,neck and legs making my mind think about the stuff i want to do with her, i eyefuck her. I imagine making out with her in the elevator, lifting her top and pressing ass through her tight legging and slowly kissing her gentle lips and neck.I just want to have a hardcore make out session with her,and squeeze her ass, eat her pussy and make her moan. Fuck even her necklace turns me on, it looks so hot on her and my eyes looks at her boobs. Often, i get dreams about fucking her and she is riding on top of me. Sometimes I wish it was real and also sometimes i feel like a creep and weirdo.
