She was good that afternoon. For the rest of the day she sat at her desk and did her work, sometimes pausing when I walked past as I started the vibe inside her. On one occasion I sat at the desk opposite her, and talked to her about a particular customer whilst I used the remote to pulse the vibe in her pussy; twice her head dropped as she nearly came, but a tap on the desk with a ruler brought her head back up and her eyes fixed on mine again as she tried to speak normally, fighting the urge to twitch and rub her clit on her chair. She came twice more that afternoon, the second time she closed her eyes tight and gripped the desk hard to stop any sound escaping as I stood with my boss next to her and chatted casually.
At half past five she rose and gathered her things together, said goodbye to her workmates and walked across the office towards the door. I had timed my own exit to coincide with hers, and managed to get to the door before her, holding it open and smiling at her as she walked towards me, watching her eyes widen as she walked into the range of the remote control and the vibe started up again. As she walked past me she thanked me, and I walked with her down the corridor, changing the intensity of the vibrations whilst chatting. As we got to her car I turned and faced her.
'No wanking before I get there.' I reminded her, 'You do want to please me don't you?'
She nodded.
I followed her most of the way to her flat, but then stopped in the garage for a few minutes, so arrived slightly after her.
She opened the door, and I saw that her bags lay on the floor as though dumped in a hurry, and she had a slight flush around her cheeks. I knew what she had been doing.
'You've been playing with your pussy.' It wasn't a question. I pulled her down the corridor and into the bedroom, sat on the bed and pulled her across my knees. I could see the discarded vibrator on the floor. Holding both her wrists in one hand I lifted her skirt and exposed her panties. I rubbed my hand across the silk, gently following the curves until I raised my hand and brought it sharply down, repeating the action twice. She squirmed.
'Are you sorry?' I asked. She didn't reply. I smacked her again, twice, harder, raising my hand to allow the sting to spread.
'Are you sorry?' I asked again. She nodded, keeping her eyes closed.
I kept her across my knee, and dropped my hand back to her panties. I eased them down, exposing her smooth but glowing cheeks. My head dropped and I kissed them whilst my hand gently stroked up and down her legs, gently parting them and moving to her inner thighs, higher with each return until they found her wet pussy. I kissed her thighs, and ran my tongue up and across her until it slipped between her cheeks, running between her pussy and her anus, probing each one in turn. I heard her gasp, so I lifted her off me and stood her up. I removed her blouse and bra, and spent some time running my hands over her tits, playing with each of her nipples in turn, feeling them harden under my grip. I removed my tie and used it to bind her hands together, then pushed her to her knees and guided her hands to the bulge in my trousers, rubbing up and down until I loosened my trousers and released my erection. I grasped her head and guided her mouth onto it, her bound hands cupping my balls while she sucked and played with my stiffening cock.
I stepped back, then I laid her on the bed and tied the loose end of my tie to the frame, so that she was laying face up with her arms above her head. I removed her panties and skirt, and, taking a pair of stockings out of one of her drawers, I tied her legs to the frame as well, so that she was immovably exposed.
