A/N: Sorry for the delayed update. See if you can guess who this mystery lady is. Not too hard to guess.
"Colorless"
Off early from work, Katsuya walks into his home and finds a very unpleasant surprise. Seto Kaiba, his lover, his life; and another figure as well. A female figure. Blonde. The two of them engaged in a kiss. A hand with slender fingers, purple fingernails running across the visible bulge in Seto's pants.
A gasp.
Caught in the act.
The shirtless violet-eyed woman turns to Katsuya. "You didn't say you were expecting company, Kaiba."
"Kastuya—" Seto mutters, but fails to meet the other's gaze.
Instead, Katsuya's honey gaze shone colorless and quiet as he walked out of the house.
