Go see the Fruits of Your Labour.

In about five minutes you make it to the shop, knocking on it's door and heading inside. It's empty as of now, and you're met with your reptilian friend manning the counter, eyes wide in excitement when your enter. If that's any indication, his serum worked as intended.

"Stephen!" He exclaims, putting down whatever trinket he was fiddling with to pass the time, and beckons you over with his hand. "The potion worked better than intended, I could tell at a first glance when I woke up this morning with a hard o-" He shuts his mouth covering it with a hand after he realizes he was speaking a bit more vulgarly than intended. "I-mh. Sorry about that. I'm just a bit excited, that's all. Would you like to see the results?"

"Of course, why do you think I stopped by- ah," You look off to the side, a little embarrassed for having to ask a guy for his name after you sucked their dick the afternoon prior. "Could you, perhaps, tell me your name, before we view the results?"

"Oh! I don't think I told you, did I! I'm so sorry! My name is Heilus. Nice to make your acquaintance, Stephen." He proffers a hand shake to you, abashedly as you asked for his name. "Either way, I'm really excited to show you the results. It seemed your, uh, administrations on my- er, sack, had a profound affect too." It's clear he's a bit uncomfortable saying things like this, but it's not like you blame him. You did suck his dick a whole ten minutes after meeting him.

"I'm looking forward to it, Heilus. Maybe we can discuss this in your office." you say a bit cheekily. "Or maybe you want to advertise the fact that your brew works so well? I'm not opposed, really." This earns you a look of shock, awe, and then finally embarrassment as he realizes you are messing with him. "The office sounds like a great idea!"
