When Rin climbed out of the subway, the Sun had already set. She didn't go right back home. She just couldn't . How could she face her Servant?
'Hello Saber, I just slept with a guy to save your life.'
Thinking like that made her feel worse. Saber could never know about it, it would kill her in ways a sword never could. It was her secret, her crime, her sentence to bear.
And bear them she would until the very end.
…
Habit is the enemy of mankind and human adaptability is its preferred accomplice.
No matter how difficult or degrading a situation, given enough time, the human mind will grow progressively more numb to its effects. The amount of time required, of course, may vary depending from the severity of the situation.
In the case of Tohsaka Rin four weeks had been enough to become more comfortable with her situation. That is not to say that she was happy with it, far from it in fact, but her stubborn attempts at not enjoying Gerard's expertise had started to become increasingly weaker over the first month of their agreement, possibly more so because the pleasure he forced her to feel did nothing but increase every time.
It is to be noted that she didn't feel any less guilty about it, returning to Saber and laying in her embrace every night made sure of that that, in fact it perhaps even made it worse. Going home at night with her body still shaking from being put through several climaxes made her feel dirtier than ever.
That didn't change the fact that keeping her voice low in the midst of intercourse had become an exercise in futility. Rin's struggle was now not getting too much into it, especially since she was expected to actively participate.
"Ah! How does.. – ah! – changing positions –hm- affects –ah! – the flow of Mana?" she asked while she swung her hips up and down over the length of his cock. It took all of her concentration not to add that extra swing to her butt that would have made it burrow just right into her.
"The position," he grunted, "changes little. It's the emotions that affects – fuck- the way Mana is transmitted. Things like… embarrassment and shame."
"You –ah- bastard! Don't… ah! Don't bully me!"
"It's research! And you agreed to it."
"Shut up! Ah!"
"Alright," he agreed, just before he lifted his torso, grabbing Rin's ass while kissing her lips.
"Hmmm!" Rin moaned into his mouth, as he used the hold he had on her to increase the tempo. With each thrust white sparks flickered across her vision. She made no resistance when his tongue slid into her mouth, reciprocating without even noticing.
It wasn't supposed to feel this good. It just wasn't.
He was spreading her most precious place with his meat rod, making her body shudder with a pleasure that neither Shirou and Saber combined ever managed, which only added to her increasing self-disgust.
Gerard broker their kiss, taking a moment to admire Rin's glazed eyes before accelerating the speed of his thrusts.
"AAAh!" Rin squealed when her pussy clenched tight around his shaft, climaxing again. Gerard wasn't done yet and kept on thrusting into her.
" Whaaa~t are you doing? " she half moaned and half cried. "I just. I… don't …! I'm going to… IiiiiH!"
Riding the edge of her first climax, Gerard brought her over a new one and still pushed ahead.
"Stooohp! You bastard!" she cried, slamming a fist against his chest. "Don't make me...!"
"Make you what?" he asked. "Tell me so that I can understand."
"Baaastarrrd!"
"I'll just keep going then."
"Noooh! I'm… I'm cummiiing!!"
And indeed she came, admitting it out loud for the first time in a month. Only then Gerard allowed himself to release his seed into her receptive womb. She scratched his back with her nails to the point of making him bleed but that was fine.
She shuddered and trembled with her head buried in his neck, trying to hide the fact that she was clenching her teeth, while her pussy drank his semen and his energy to the very last drop.
"Right, that much isn't enough to fill your Mana," he considered after a while. "We should do it one more time."
"Ah…," exhaled weakly. "Okay…"
He lifted her and himself from the bed, shaft still hard and buried into her, holding her by her ass and pinning her back against the wall in a precarious position. She was forced to wraps her legs around his waist or she would fall.
"What are you doing?"
"What does it looks like?" he asked and again begun pumping into her.
"Let me down… Not like this… Hmm!Ah!"
But Gerard was deaf to her complaints. Though he was holding her up, the body natural reaction when suspended midair was to cling to the nearest support and Rin did exactly that. Her pussy tightened magnificently around his dick, squeezing harder than ever.
"AhhhnnN!" she moaned into his shoulder, clinging to him with all four limbs.
"Do you like it this way, Rin?"
"Hmm!" she shook her head in denial, unable to trust her own words.
"Is that so? Guess I'll have to try harder then."
As promised his efforts redoubled and Rin was yet again approaching the point where she could no longer think. Biting her lip she prepared herself to have another orgasm wreaking her mind, but just as she was about to do just that, Gerard slowed to a near crawl.
Her pussy clenched, but it was like grasping at straws. She gasped in something that was relief tinged with disappointment.
Gerard gave her no chance to regain her bearing and increased his pace once more. There she was, approaching again that dreadful edge, only to be stopped and brought down empty another time.
She swallowed a curse. What game was he playing at, this time?

AN: I am aware that Rin has more than enough Mana to keep Saber alive and then some. I forgot to specify that she's overworking to keep up her reputation tarnished from Shirou's Sealing Designation in order not to be banished from the Clock Tower, thus losing any chance to help him in any meaningful manner. She also has a part time job to cover the expenses of every day and to pay for her not at all cheap jewelcraft, meaning she has less time to rest and to recharge.
