System, why isn't the main quest finished!?
Inside the closet, Kaede began demanding her rewards. The quest was to "personally participate in a party." Does hiding in a closet while Rin fucks her friends count?
[The Host is merely hiding in a closet. This is not participation.]
So what if I'm in the closet? Isn't "Observation Play" a thing? In H-manga, the hidden observer is a key part of the scene! This party wouldn't even happen without me!
[Logical and convincing. The Host has persuaded me.] [Main Quest 1 complete. Reward: Mystery Mega-Bundle.]
A beautifully wrapped gift box appeared in Kaede's vision. She clicked it open with anticipation.
[Congratulations! You have received a 'Reinforcement Mega-Bundle' X1. Use now?]
What's in it? Kaede asked warily. It better not buff my sensitivity again. Her sensitivity was already at 3x; she couldn't imagine what would happen if it went higher. She'd be relegated to the end of every party just to clean his "stick" with her mouth because she wouldn't be able to handle the friction.
[The target of this system is Rin Ito. The bundle will grant random reinforcements related to him.]
Kaede sighed in relief. Open it!
Dynamic music played in her head, and Rin's status panel appeared.
[Ding! Rin Ito has gained 'Conception Probability Increase' (67%).] [Ding! Rin Ito has gained 'H-Manga Volume' (46%).]
What the hell is this!?
[Any female filled by Rin Ito has a 67% chance of pregnancy, even during a 'safe period' or while on birth control.] ['H-Manga Volume' increases his current ejaculate volume by 46%.]
Kaede gasped. 67% chance to get pregnant even on the pill!?
[67% is the base value for safe periods. During ovulation, it increases based on individual physique.]
Kaede caught the loophole. If he doesn't cum inside, the chance is 0%, right? And the system said birth control is ineffective, but it didn't say condoms are.
[Correct. Even this system cannot cause pregnancy from a distance.]
And what about the 'System Condoms' (Spirit Shields)? They stop the sperm from reaching the egg, right?
[Correct.]
Kaede relaxed. The "Spirit Shields" would protect the other girls unless she purposefully didn't use them. But for herself... she'd just have to make him wear a condom. Wait! She had considered going raw during her safe period once... the system really didn't want her getting filled, did it?
Angry, she looked out at the party. Rin's fluids were visible on Kaguya's thighs. He was her boyfriend, yet every other girl got filled while she had to use protection.
As for the "H-Manga Volume"... Rin was currently producing about 137-161ml per load—roughly half a can of Coke. Not quite full "manga levels" yet, but far more than a normal human. Without the Spirit Shields, he would knock these girls up instantly.
Hmph, let them get pregnant? Not until I've graduated and had my own baby first!
