Tracy has some answers

After leaving Tracy to shower for a while (now nearing an hour), you begin to grow impatient and decide it's time to find out what happened with her post on the online forums. She better not have forgotten to do it or else she would be in for some serious punishment. You head to your ensuite and as you approach your bedroom you start to hear some moaning and can immediately guess it's source. Entering into your bathroom you find Tracy bouncing back into the dildo from earlier, which she's now attached to the wall of your shower. You're now close enough to hear her panting as she smacks her ass cheeks into the wall repeatedly. She seems to be quite invested in her current activity as she still hasn't noticed you yet. Upon closer inspection, peering through the glass wall you're surprised to find that the dildo is actually entering her ass and not her pussy. She seems to have taken a quick liking to anal and based on her current pace, has greatly improved her capacity to take it up the ass.

"I've been waiting for you for quite some time now slut." Tracy turns her head to you with surprise, although doesn't stop bouncing on the dildo firmly wedged up her ass.

"Sorry sir, I got distracted with my new toy. I'll be out straight after my next orgasm."

"So you managed to cum from anal?"

"Yes sir, three times already, with a fourth getting close. It feels like a whole new sensation, maybe better even. Completely different to cumming from being fucked in the pussy, although I still squirt just the same." She moans in between her deep pants.

"I'm impressed. Well I'll be waiting outside for you. Don't take too long."

With that you leave her to her business and smile slightly as you hear her whorish moaning resume. Tracy finally exits the bathroom wrapped in just a towel when she's done. She grabs her laptop off the desk before joining you on your bed.

"So I couldn't help myself and checked the website a few times throughout the day and you'll be happy with the results."

Stacy logs into her account and reveals dozens of messages from strangers online, all stating that they live in your area and expressing their immense interest in taking part in her first gangbang, you couldn't have hoped for a better result. Most of them even attached images of their erect cocks at the sight of Tracy's photo and post. Whilst you read the details of the messages, Tracy seems to have her eyes fixated on the images, her breathing getting slightly heavier at the sight of all those dicks she's brought to full mast.

"This is amazing, it seems we have quite the selection of folks to choose from. How many do you think we'll need for your first time?"

"I was thinking maybe we start out with four others. But the choice is ultimately up to you. Like I said before, I'm just a possession of yours to use however you please."

"I think four is a good amount to start with. How will we choose which four though? Should we get them to send photos and you can decide which one's seem the most attractive to you?"

"I don't care about looks, I only care about the meat dangling between their legs. I was thinking I could sift through the messages and sort them by size and then reply to the biggest four." Tracy bites her lip as she says this, looking slightly nervous and aroused at the same time.

"Sounds like a plan, tell them it's happening this Friday evening. If they're still interested then send them our address, hopefully none of them are serial killers of anything."

Tracy laughs and begins her task of sifting through dozens of dick picks.
