I looked at her typing away in her individual office all alone. She didnt even know i was there. She was working late, very late indeed as it was only herself and me left in the building. I'd been round and checked. I watched her type from the doorway, an idea filtering into my mind as i crept behind her.
She was sat at the desk wearing a purple blouse and black skirt with pantyhose underneath. Her black high heels matched her skirt as she typed away still oblivious to the time or her surroundings.
Suddenly i pounced from behind, clamping my hand over her mouth.
"Do whatever i say and you wont get hurt" i whispered as she nodded tentatively, caught by surprise with my actions. I was wearing a black t-shirt and trousers with a balaclava.
"Strip...i do suggest you hurry with that too" i smirked as she slowly raised herself from the chair. She removed her blouse and skirt for me but i made her keep the rest on. She was now dressed in a red bra with a matching thong. A pair of pantyhose covered her long legs. She was a curvaceous, slightly older woman in her mid thirties with blonde, dyed curly hair that flowed down to below her shoulders.
As soon as i had stripped her down i grabbed the rope from my bag and began by tying her wrists and elbows behind her tightly. Two further ropes followed above and below her boobs, pinning her arms to her back before i took great delight in securing a tight and effective crotch rope. Ropes around her thighs, knees and ankles followed before i sat her on the floor and finished her bonds with a large red ballgag.
"Much better" i teased as i groped at her large boobs. She began to moan under the gag.
"Hmm, the office to ourselves, i wonder what i should do with her?" I thought to myself playfully.
