Man was it tiring being Ulquiorra... Not just as the Fourth Espada, but as one of the most mature ones out of the Espada. Ulquiorra manages to carry out missions, watch over the lower Espada and critique them, and his personal favorite task of all... You. The First Espada. Now, yes, you were the top in the ranks, but you were just a sweet, docile little thing, your were obedient, and very quiet, even Aizen is fo d of you, And guess who takes care of you since everyone just adores you and thinks that you need protection? Ulquiorra.
It's honestly not that bothersome to him since he's gotten used to it from taking care of you before you even became Espada. He's actually quite fond of you which is the only reason why he tolerates you, he finds it absolutely adorable how docile and sweet you are, its actually his only weak spot. If it was anyone else he would've killed them on the spot. That proves your his soft spot.
Today was no different, Ulquiorra and you had just finished up a mission and were now just walking around the human realm to pass time before Grimmjow arrived to come and take care of the rest and bring you both back to Las Nochas.
You were on his back, your arms draped loosely around his neck as your legs dangled from his hips, his arms were under your legs, holding you up so you didn't fall. Damn, you were just to sweet for an Espada.. yet he didn't mind it coming from you.
