The smell of smoke and blood waft through the air, a rather unpleasant atmosphere. This was normal for a mage, but... “normal” doesn’t help relieve the overwhelming pain in your chest. It’s the 5th Holy Grail War, and you made a few alliances. Most notably with Rin Tohsaka, a beautiful albeit pretty harsh girl. She was pissed at first. She wanted to be Saber’s master, but it ended up being you who was the master of Saber while she was stuck with Archer. She got over it eventually, and you two got VERY close. It wasn’t time to think about that, though.

You lost your Servant during this final battle. Sure, you’re a very talented Magus, but there’s only so much you can do. The enemy’s servant blasted a hole through your chest. It was hard— no— impossible to breathe. Rin won. She won the Holy Grail War, but... at what cost? You’re going to die. Well, you WERE.

In order to save your life, she used her wish to save you. It was a spur of the moment thing, not even she knows why she did it. Her entire life, she trained to win the Holy Grail War... just to use that wish on you

“I’m such an idiot... falling for a guy like this, what have you become, Rin Tohsaka...? No, that’s not what it was. You’re just really kind...”She mutters to herself, not fully believing in herself

A few hours later, you wake up in her room, head pounding. Your mana level is low, you can tell that much. Just as you start to get up, Rin walks in the room.“...you’re finally awake. You’ve been out for a day. I-“ *She cuts herself off, shaking her head* “No, we won. I used the Holy Grail to save you, plus give you a few upgrades. But your mana level is still really low.”

She turns away, blushing and pouting“And to fix that... we need a... mana transfer.”Confused, you look at her quizzically

She sighs at your lack of knowledge, before continuing“In other words, w-we must become... one in body and mind.”She purposefully leaves some details out to avoid the embarrassment. Seeing as you’re still confused, she gets visibly pissed off

“Ugh! Can you be smart for once?! We have to have s-sex! And cum at the same... time...”She almost completely shuts down at the fact that she said it spontaneously. All she wants is to crawl into a hole and hide

“Hurry. And. Take. Off. Your. Clothes.”She demands you, unwilling to show weakness to her mate

She begins to remove her own clothes, before looking over at you.“S-stop watching me! It’s weird...”

After a few seconds of silence, she stands before you, naked besides her thigh high socks. You begin to tell her she should probably take those off too, but she seems pissed enough.“Stop looking at me like I’m prey... it’s embarrassing.”She sits on the bed beside you, her long, slender legs and foxy figure bare before you. Despite acting hesitant, she lies on her back and spreads her legs slightly, submitting to you.

“...go ahead. I’m just glad it’s you I teamed with.”
