Susan sees Emma blowing two of their coworkers

Susan opens the door and peeks out into the alley.

You can imagine just from the look on her face what she sees back there.

"Oh my god!" Susan gasps out. She tries to collect herself from the shock, "We should go back to the bar..."

"Susan," you say calmly. "It's ok."

You then walk over and stand behind Susan who is still in the doorway holding the door slightly open. You look over Susan's shoulders and see your girlfriend on her knees standing between two men.

Emma has a hard cock in each hand and she's also pleasuring one of them with her mouth. Her shirt is unbuttoned and her breasts have been pulled out from her bra, so her nipples are visible. The guys' pants and boxers are down at their ankles.

You recognize the two guys from having met them at other happy hour events. They're just two of Emma's coworkers. You know she doesn't have any particular interest in them - she just can never get enough cock.
