I walk up behind you and massage your shoulders through your shirt, reaching round I loosen your tie and slide my hand into your shirt, running my nails over your nipples and making you moan. I pull off your tie and tie your wrists together, your arms wrapped round the back if the chair.
Moving round to your front I open your fly, pulling your partially erect cock out I coat my hands with lube and start working them up and down until you're fully hard. I reach down to get at your balls, cupping and squeezing them before running my nails over them hard and fast.
Going back to your cock I alternate between hard strokes along the full length and massaging the head with my fingers. I slide my hands over you, each hands stroke starting as the other moves off, I feel your cock throb and pulse as you get near cumming so I move off to cup your face, kissing you deeply as you groan your frustration into my mouth.
