"Saber! Why don't you come in the water with us? It's every refreshing." Shirou called out from pool.
"I am just fine where I am, Shirou." Saber said stiffly from where she was standing at the pool's edge. Though the Clock Tower usually spent its luxury money and frivolous ostentation and art work, some of it did go to its public faculties. On such faculty was a recreational center, which happened to have an outdoor pool. When a particularly good stretch of warm weather came to London, her master had decided that it would be a good time to make use of it.
"Oh come on Saber." Rin called out, treading water next to Shirou. "We didn't come here just so could stand in the sun. Besides, I got you that swimsuit just for this."
Saber had to force herself not to cover her body with her arms as she remembered what she was wearing. Her master had told her that it was called a 'bikini', but really it just seemed like a strip of white cloth around the chest and another around the nethers. She usually wore under things more substantial than this! Though this wasn't the first time her mater had suggested she wear something… exposing, this was the first time she had done so outside of her home. "I simply do not see the need to enter the water is all."
"Why not?" Shirou asked as he paddled closer to her and rested his arms on the lip of the pool. "Didn't you ever spend time relaxing by swimming in lakes or ponds in the old days?"
Saber looked off to the side. "I was much too busy for those sorts of things. My training for knighthood when I was a child prevented me from participating in such frivolousness. Even more so with my duties as a King as I got older."
Shirou frowned at her for a moment, as if mulling over her statement. Then his face lit up like he had a thought. "Wait, are you saying that you never learned how to swim?"
Saber felt her face blush at this. "O-of course not!" She said as the man hit the nail right on the head. "That is utterly preposterous! And besides, even if that was true, I can walk on water, thus making learning the skill irrelevant!"
"That's probably why you don't know how in the first place..." Shirou muttered. "Tell you what, why don't I teach you now?"
"What?" She said in surprise. "I don't know..."
"Yeah, that's a great idea!" Rin said as she pulled herself out of the water. "Besides, it'd be a waste if you didn't get at least a little wet." Her master then gave a small leer and wrapped her arms around her Servant, her wet body soaking what little clothes Saber had on.
After much more blushing on the former King's part, she eventually found herself standing in the shallow end of the pool with her two lovers. "Alright," Shirou said. "Let's start with something simple. Try floating on your back."
Saber gave a small scoff at this. Honestly, that was a little basic. All she had to do lay down-
Naturally, the moment she tried this she started to sink. She flailed wildly for a few moments before Shirou and Rin pulled her back up to the surface. "Geez, you're too stiff," Rin said. "It's like you have a metal pole up your spine."
"A-a King must always have good posture." The blonde woman sputtered.
"Well, I think even a King must make allowances for the laws of buoyancy." Shirou remarked dryly. "Alright, try it again, but this time let yourself relax and curve at the middle."
She didn't quite succeed that time either, but she didn't get too far down before the other two reach down to support her. Rin gave her a gentle push on her middle to coax her into position, and soon the two had let go of her and she was floating on her own. After a moment she had forgotten her trepidation and was experiencing the rather novel sensation of weightlessness. True, she had been in tubs before, but this was much more… free and open. In spite of her herself, a small smile formed on Saber's face.
"See? I told you it was fun." Shirou said, looking down on her with a smile of his own. "Now, on to the actual swimming."
Saber was then flipped onto her stomach, her and Shirou's forearms griping each other to keep her afloat. He then gently led her around the shallow end, instructing her how to kick her feet. In no time she was quickly learning what was apparently called the 'doggie paddle'. It put her into a mildly embarrassing pose, but she quickly ignored it for the oddly thrilling sensation of moving about the water on her own power. For someone who had been bestowed the favor of the Lady of the Lake, she wondered why she had never done this sooner.
Eventually Saber came to a stop and only briefly flailed before finding purchase beneath her feet again. "That was… pleasant." She finally settled on. "I never knew that being in water could be this… fun."
"Oh, there are even more fun things to do in the water." Rin said, a smile slowly forming on her face again.
"Like what?" Saber asked.
She was genuinely curious about what her master was talking about until Rin's smile turned into a rather familiar leer. The last thing she heard before the dark haired woman pounced on her and sent them both under the water was Shirou's panicked cry of "Rin! Not in public!"
