Condition

So, I have this issue where if I am in contact with a girl for long enough my desires builds up... she looks quickly at Ellie who blushes hard, you know she has been focusing on medical studies and when she doesn't say anything to counter what your mom says she resumes saying.

"It builds up over time and continues to get worse to the point where it cannot be relieved by normal means, it requires a girl to release these desires. while normally it would be fine and all but you are planning on having her move in soon right?"

"Yes" you say realizing that she hasn't told you yet that she has got a massive cock and you can't just say you know already because that would out your peeking earlier.

Your Girlfriend has started to tremble a bit, before you can ask her what is wrong your mom continues "Well it's fine now but if we are going to be together more often it will eventually reach this point so I want to ask you to let me use her when it becomes unbearable please!" she still hasn't brought up the fact that she has got a massive dick and probably is going to have her relieve that... you ponder what your girlfriend would look like sucking on her cock and notice you can't because you don't really know how big it is when it's hard.

You look to Ellie she is now trembling a lot with tears starting to form in her eyes, "What's wrong? you put your hand her shoulder" she jumps a little as if just noticing you were next to her

"Oh... I'm just very worried for Ms. Jullia.... I've heard about the condition in my classes it can get pretty bad, and its severity changes based on age..."

She must have some history with this condition if she is like that.

"So what do you want to do, you're the one who will have to do this after all"

"I want to help her... Please... Let me relieve her when the time comes. But if you don't want to we just have to hire a girl to take care of her"

You think for a bit over your options...

I will have to come up with an excuse if I want to find a way to study this condition and maybe its tied to her having a cock.

I can go with it and just accept that she will be sucking my moms cock regularly

or deny her and hire someone else to take care of her.

Your mom speaks up "Well I'll let you two decide I'll be upstairs don't stay up too late" she kisses you both on the head as she heads out.
