Ignis chuckles a little at how Felih's cock is saying 'hello' as it always does. He loves how expressive it is as the rest of Felih.

"I will and more," Ignis promises fervently, kissing Felih's hair. "I won't make you wait...."

He really can't let him wait. Felih's so obviously pent up, already dropping full sentences for pleas. The first time they're together like this again is always a fast dance, so desperate are Felih's needs. Ignis could last longer if it was just him, but looking at Felih makes him just as desperate. Because the sooner they are done with this, the sooner Ignis can recover and have Felih inside of him....

Felih's already relaxed, of course--his body always seems ready for this. Ignis pulls out his hand, rubbing the lube that has pooled on his palm to lube up his erection. The only thing he pauses for is to dry the lube off his hand so that he can hold Felih properly without his grip slipping.

He aligns Felih's hips once that business is done, letting just his tip slip inside him. Then he claims Felih's lips, enjoying the power to muffle Felih's reactions within his own mouth. Felih doesn't need it to beg or plead anymore, either, as Ignis lets Felih slip down the wall just as he thrusts up with his hips, letting gravity increase the force Felih feels inside.

This was why he wanted Felih to still wear that robe: to avoid splinters from all the movement they'll be doing.
