He cowers downstairs

Cursing his cowardice, Adam stayed paralysed at the bottom of the stairs. He listened intently, their voices now a lot clearer.

"Since you were so kind with helping me with my package downstairs, I think it's only fair if I help you with yours," Aga teased. Adam could imagine the salacious look on his girlfriend's face as she spoke those words.

"W-what are you doing?" the man's voice stammered. "Please, I don't want any trouble."

"Shhh," Aga hushed, "just relax and enjoy yourself. I know I am."

There was a brief silence and Adam imagined what was going on. He couldn't believe he was listening to his girlfriend's voice, and the words she was saying, without even intervening.

"Mmm," the delivery man groaned. "That feels good."

"You like that?" Aga purred. "I bet your wife never does this to you."

Adam heard another moan, and imagined his girlfriend kneeling before the man and sucking him off. His own cock twitched at the image, although he couldn't help but feel jealous of the stranger. Only moments ago, he was the one being sucked off by Aga.

"Fuck," the delivery man grunted, "that feels so good."

Adam's cock was now fully hard again, and he was tempted to touch himself. Instead he just listened to the sounds coming from upstairs. He could hear Aga laughing between her sucking noises and the man moaning.

"I think you're getting close," Aga teased. "You can come whenever you like. I'm ready."

The man was panting, and the sounds of Aga sucking his dick had become louder and quicker. Suddenly, the man gave a loud moan.

"Fuck, fuck, fuck!" he yelled.

"Ooh!" Aga squealed.

Adam realised that the man must have been coming in his girlfriend's mouth. He could hear a wet slurping noise as the man came and Aga swallowed his cum.

"Oh wow," the man said, sounding very satisfied.

"Mmm, that was so good," Aga purred. "I bet you've never been tipped like that before, huh?"

"I- I've never been tipped like that at all!" the man exclaimed. "That was amazing."

Adam could hear the sounds of movement upstairs and then a zipper being done up.

"I have to get back to work," the man said, a tone of regret in his voice. "But if I'm ever in the area, can I come visit?"

"Maybe," Aga's voice answered coyly. "It depends if I'm feeling generous that day."

The delivery man chuckled, and then Adam could hear the footsteps approaching the stairs. He scrambled back towards the kitchen, trying to be as quiet as possible. He made it there just as he could hear the delivery man's steps down the stairs. Adam waited until he heard the door open and shut, and the van engine start. He could only assume that the delivery man was leaving with a grin plastered across his face.

Adam stood in the kitchen, dumbfounded as Aga walked in.

"See, I told you I'd get rid of them," Aga smirked.
