Gonkillu! Smut! Oneshots!
Cross-posted Gonki! Of mine from ao3! His erection is still painfully hard, but he ignores it. It isn't important. Killua is. If it had a mind of its own, it would slap Gon across the face, but Gon would fight his own dick for Killua. The cover is my edit! Link inside! First chap!
