"Show me your dick"

Both of you were completely thrown by what you said. If he was shocked, you were completely flabbergasted. Never have you wanted to see a penis before, now you're asking random guys to see theirs?

"Uhh..." The delivery man started, unsure how to respond.

However, his hands made their way down. They made short work of releasing his dick to the world. You were mesmerised. It wasn't like a swinging pendulum or microdick. It was a regular human penis on a regular guy. But for some reason, your mouth watered at the sight, your heterosexuality crashing down. The delivery man was getting uncomfortable.

"Can I-"

"Let me suck it." You say, not thinking.

You're immediately stunned back to your straight life, not believing what you said. You're about to apologise and just sign for the package when you hear fabric hit the floor. The delivery man has completely exposed his lower half, looking at you expectantly. Tentatively, you kneel before him. You know you're going to do this, despite any regard to your, or his, sexuality. You grab the flaccid member, bringing your face towards it. You take a sniff at his blonde pubes, intoxicated by the musk he's permiating. Slowly, you take the head of the dick in your mouth. There's not too much reaction from the delivery man, as he watches you suck your first cock. In fact, his face seems to be fighting a losing war, trying to **** himself out of this situation. You begin to suck on his dick, trying to do things you would want done. Slowly, the delivery man gets hard in your mouth, allowing you to begin slutting yourself out. Quickly realising you're not good at taking long, phallic objects ("yet" you think to yourself) you focus on the head and coat the rest of the dick in saliva, jerking him off as you suck.

"Mmm, fuck." he groans, beginning to appreciate the blowjob.

His groans encourage you on, as you begin playing with his foreskin with your tongue. As your heterosexuality begins to diminish, you begin getting more excited in your fellatio. Your eagerness is not in vain, as the breaths of the delivery man quicken. Your hand travels downwards, playing with his tight balls. That seems to does it for him, as you feel them tighten even further.

"Oh fucking take it dude!" he yells, pushing your head down all the way.

You **** and splutter as you feel the cock rammed down your throat. Cum erupts directly into your gut, though your attempted coughing is bringing some back out your mouth. When he eventually finishes cumming, he awkwardly passes you the clipboard to sign. You meekly take it and sign as he pulls up his bottoms to re-proffesionalise himself. As he leaves, you quickly feel guilt settle in, especially as you look down and find your own shorts soiled with cum.
