A midday rutting and evening

Saber was getting what she needed after such a day of being toyed with for so long. She was going to have her release. She rode Shirou's shaft as he pounded up into her, diving Divine boons against draconic desire again. She gripped his shoulders as he kept going, her own thrusting down increasing her pleasure as she moaned. It took only a minute for Shirou to climax into her again, helping with her own release. She sighed as she came shortly after, Shirou working up for a second round. Well, the king wasn't going to object...

Unnoticed by either of them, the two were being watched by a few others, one much more subtle about it than the others.

The blue haired woman from before was watching from above, the Caster servant in spirit form to spy on the distracted sexy figures beneath her. "oh my, I thought she was beautiful before, but how shameless... and her Master, oh he's a prize catch as well~." She thought to herself. If she'd been in a physical form, she'd be rubbing herself off a few times as she watched. "I simply must have that Saber." The Blue haired mage drifted back to base in spirit form. She needed to plan for tonight.

One being relatively less subtle was watching from behind, an albino little girl watching from a bench nearby, her jaw dropped as she watched. Ilya twitched back and forth as she watched, resisting with all her might the urge to dive her hands between her legs as she watched her sexy adoptive brother ream his Servant. Eventually she couldn't take it any more and ran off, hiding in some bushes as she treated herself to the relief she desperately needed.

"Stupid sexy Shirou!" She grunted under her breath as she relieved the tension she'd gotten from the minute or so of watching that. It was perfectly normal, of course, but her her adopted little brother was definitely enjoying that servant. How she wished that was he- Stop that Ilyasviel! You're the one who's going to Cum on top- come out on top here. Stupid sexy Shirou.

It was many minutes before she had it out of her system. By the time she was done, Shirou and Saber had finished and were heading home, meats and new clothes in tow. Ilya pouted, stamping her foot in frustration over everything. That was it! She was going after Shirou tonight and ending this!

And the last observer wasn't noticed by anyone, even the Caster. But that makes sense. After all, it's normal for Assassins to be masters of stealth...

Shirou and Saber returned home with the supplies, Shirou saw Sakura was cleaning. The instant she locked eyes with Shirou, she collapsed against a wall. "W-welcome back, s-sempai." She said, panting hard as her face returned to its flushed state. Immediately worried for her health, Shirou escorted her back to her room. "Sakura, You really shouldn't be up if you're this sick. The normal thing to do if you're this unwell is to try and get some bedrest." He helped put her back in her futon, using his normality to try and help her recover.

Shirou then spent most of the day discussing things with Saber, they also invited Rin over to strategize. Taiga appeared on her own as they prepared dinner, and they had a reasonably pleasant time. But Shirou and the other's minds were elsewhere, tonight was going to be important...
