You remember your training and breathe deeply in order to control yourself. In the time it takes for Circe to recover her lost footwear, you manage to steady your thoughts and finally focus. However, this does not mean you will completely ignore your urges, but rather, will try to be as smooth as possible in order to satisfy them.
With heavy steps you approach the hawk witch. She turns around when she notices you.
"Piglet? So you are going back on your word and coming back for more?" She smiles bewitchingly. However, you ignore her words and continue approaching.
"Huh? P-Piglet?" She looks rightfully confused, your actions are just too strange. You don't stop though. Once you are close enough, you extend your arms and wrap them around her small body, pulling her into a hug.
Cat and Emiya give some looks, but think nothing of it aside from Cat's mumbling about stealing her master(husband).
Circe is very confused. "D-Did you like the kykeon that much..?" she barely manages to mutter. After a bit, you finally say something.
"...Circe, meet me in my room later." You whisper to her pointy ear before very mechanically separating from her and leaving the kitchen, heading straight to your room.
Once there, you lie down and finish calming down. Really, you have seen soles many times now, with the amount of female servants that wear sandals or go barefoot, so why did this time cause such powerful effect? Could it have been the kykeon? Could it have een because it was Circe? Or could it have been because of a mixture of the two?
You attempt to meditate as the raging boner you acquired doesn't calm down.
Some time passes, you don't feel your face as hot anymore and you head is much clearer, but your hardened penis still doesn't go down. You attempt to masturbate but doing it too hard hurts, while doing it too softly doesn't accomplish anything. You await for salvation to arrive once she answers to your summon in due time...
After seemingly an eternity of crushing your face with your pillow, a soft knocking on the door alerts you. Without waiting for an answer, the door opens. When you look, what you see is none other than the Queen Witch of Aeaea Island. None other than Circe, now wearing her usual clothing. You sit on the bed to face her.
Her face is red though, almost as if she knew what you called her here for... After a while of just watching each other, she suddenly bursts into speech.
"G-Geez! You could have asked more normally, and at a time we were alone! The archer and berserker didn't stop teasing me after you left!" She angrily yells, but not that loud because she probably doesn't want to be heard.
So that's why she was blushing so hard. That explains it.
"A-And moreover, what got into you, popping a boner in the cafeteria?! While my kykeon can have the effect of replenishing and even increasing vigor, it musn't have been enough to achieve that result just by itself." She looks down on you, directly at your crotch. Unfortunately, your Chaldea-brand pants don't hide your erection very well. Upon noticing this, you immediately close your legs.
Circe sighs. "And now you called me here to take care of it, isn't that right Piglet? I-I mean, I don't have a problem with that. Really, I would have c-come if you called me even without that show." She takes some steps closer, but stops before reaching the bed. She then fidgets aggressively.
After a bit of looking around for no reason, she once again speaks up. "R-Really, what even do you want me to do..."
