A male coworker

Your pussy is begging to be fucked and you finally decide to give in

"Old Rule: Secretaries must be obey any sexual request"

"Old Rule: Lesbian sex is not considered inappropriate at work"

"Old Rule: Sabrina is very horny when at work"

You get in the elevator to go to your office, after one floor the elevator stops and a coworker of yours enters. He clicks the 20th floor and says "This should give us enough time not to get caught, suck my dick". Blowjobs are still taboo, so you risk getting fired, but the rulebook forces you to get on your knees sucking. The risk arouses you even more that you normally would, you start sucking voraciously.

His cock is on the smaller side, so you manage to push it deep enough in your throat that the tip of you tongue is now licking his balls, quickly you feel him tense up anticipating the orgasm, but you are not done yet. You slow down a bit and slide your hand behind his leg, up the thigh and finally start stroking his asshole "Not ther..." he stammers, but he doesn't finish the phrase so it doesn't count as an order.

You first slide in the tip of your finger and then slowly but steadily all the rest, he moans. You are almost at the end of your (elevator) ride, so you decide to let him cum: you hasten the pace of the blowjob and insert a second finger in his asshole, he pushes all his balls into your mouth and cums directly into your throat.

He pulls up his trousers just as the elevator opens to reveal several other colleagues waiting.
