With her mouth

Sarah takes you cock into her mouth and proceeds to suck on the head, with all her might.

"Mmmm, yummy," she says before running her tongue along the underside of your shaft and sucking your head back into her warm wet mouth. Her head bobs as she picks up the pace and you grip her hair in your fingers moaning, you can feel the rush of your semen preparing to escape its prison.

"I'm close Sarah!" You yell using all your strength to prolong the sensation of this nympho hungrily consuming your cock. It's all in vain though as Sarah does something you hadn't prepared for and swallows your shaft into her moist tight throat, grunting you feel your dick convulse and shoot your load straight down Sarah's neck.

Sarah pulls you out of her mouth and throat slowly and with a satisfying pop, the best blowjob of your life ends your slobbery cock settling down satisfied.

"I hope that was good," Sarah says purring. As you both lay there basking in the afterglow of what just happened between the two of you, the door to the equipment room suddenly opens.
