It's an early morning, and Killua decides to give his husband a little something special for his birthday.... Lemon. Smut. YOU SEE THE TITLE. ⚠ Gon and Killua are ALWAYS over the age of 18 in my smutshots ⚠ Will I ever write anything normal? Probably not. ENJOY THE SMUT! Seriously, you better enjoy it. I spent too many hours.
