You get more and more excited as they describe what they want you to do, some of what Evelyne was saying does not fully make sense, but there is no refuting the fun that Cammy is proposing. You say “OK, what do you need me to do?”

The twins squeal with delight, and start working on getting your pants off. Evelyne says clinically, “First I need to know how much you penis grew after you last session?”

You answer “I didn't measure, but about 2 inches.”

She responds, “I take it that this was your first Penile vore experience?”

You say “Yes that was my first time, it has never done that before.”

She says “Good this data fits withing the theoretical model. Do you know what may have triggered this reaction?”

You think for a minute “I really haven't thought much about it. The best I can think of was that the entry test was pretty intense.”

She ponders for a moment “That is very likely, I heard that you got the second highest score on the pain threshold test, second only to Diana, and highest score a male has ever received on record. There was likely a physiological reaction.” She then says pointing to your member now well exposed, and currently being teased by the twins. “Finally I need that thing to be in the relaxed state. I don't suppose that you have sufficient level of control to get it to relax?”

One of the twins, Tammy you think responds before you can, “Nope! he's a guy, there's only 2 ways to get that sort of thing to happen, first is to make him cum, and the second is to force all thoughts of beautiful women from his mind.”

You finish, “And I'm afraid being you your presence is going to rule out the second option.” Smooth you got her to blush.

Evelyne responds, “Fine you two get his penis to relax, and I'll meet you in the second floor common room in a few minutes. Do be sure to get an accurate measurement, and don't do anything to skew the data.”

The twins grins evilly, they're planning something, only thing is, you're not sure if you're going to love it or regret it.
