   Summary

   There was little slick from Cross, and the friction became tenfold, Killer could tell his dick was chafing from the lack of wetness but it only served to set his soul ablaze, “Woah wait-!”

   Cross slowly dragged himself off the hardened organ, Killer supporting him by using his remaining strength to keep him from hopping back down. “You want lube? You better come.” He demanded evilly, as he shoved his pelvis back down.

   OR; Cross and Killer fuck nasty.

   Prompt: Painful sex
