I think Elias should be a monsterfucker. Btw. Look humans are alright, but after a good few decades they start to get. Bland. I think Elias would love subbing for a huge, terrifying monster that could easily snap his neck but doesn’t, and I think he would ESPECIALLY love domming one. Bringing it to it’s knees. Exerting power and control over a deadly killing machine that could make all his worst fears come true if it weren’t so busy whimpering and pleading for more, harder, deeper. Anyway I think when he sees monster Jon he probably has a good handful of Emotions about it, but a solid chunk of those are “I need to get that thing pregnant NOW.” Just. Pure, unadulterated lust. He learns monster!Jon has a cock now (with BARBS. and a knot) and immediately decides that he needs that thing inside of him and as soon as possible. Thinks about Jon’s stomach swollen with his offspring, tits full and aching with milk, and gets so hard he almost passes out. As soon as monster!Jon spreads his legs Elias is there. And he is letting out 200 years of pent up monsterfucker horniness. (Look my man is terrified of death. Odds that he has felt safe enough to bed a monster more than maybe a teensy handful of times? Low. And now the opportunity to dominate and breed an incredibly powerful monster arrives?? He Is Going To Fuck That Monster.)
