You have to find out.

You lay on your bed with your daughter, both of you naked, and contemplate the feelings and sensations you are experiencing. Your daughter starts to fondle your soft cock, but you know that you have some notes to take, and soon.

"Soon Kira, let me take some notes real quick," You say as you grab your phone and head to your home office.

Kira complains, but not too much, as you put on some shorts and leave the room. You open some documentation you have on the disease and begin looking at the known cases where sexual activity increased, and where nymphomania was noted.

You also start looking for data on side effects for donors, and there is no data at all. It seems that worldwide no donor has ever presented any symptoms, so maybe it is all in your head. You ask to meet a colleague the next day to discuss something important, a colleague named Maria you have known since freshman year in college, who you trust like a sister.

This is tricky ground, what you are doing is illegal, but who can you trust if not Maria?

Kira come up behind you, "Working today dad? It's Saturday?" Her hands are on your shoulders in a very comfortable way.

You feel her soft breasts on the back of your head, that makes it hard to think.

You turn and look up to her, "In my job, there aren't a lot of full weekends off baby, you know that." You say this with a smile, she already knows this well enough. She leans down and kisses you, and you see her beautiful naked form, as Kira seems to barely wear any clothing anymore.

Kira gets on her knees beside you as you work, and takes your soft cock out of your shorts.

Fuck she is ravenous, you look at the clock, it is about time for another dose for her. Not her fault, not her fault at all.

You still have work to do it you are going to figure this out, you can't just fuck and sleep over the weekend. Kira might not take it well, but this might need to wait, you need to be prepared to meet Maria.
