Anything Hammer crafted with his own two hands was going to do more harm than good for the user-- as long as it wasn't supposed to benefit Tony, he wasn't too worried. He groaned as his tortured bones settled back into his seat, head dropping back with genuine exhaustion now and glaring blearily at the ceiling. Hammer's ability to lie to himself was constantly awe-inspiring, but Tony didn't even want to tackle the mental contortions he would have to put himself through to be convinced Tony was so easy to break. He shrugged his tight shoulders like he couldn't imagine what Hammer was blabbing about, sighing and muttering, "I've been waiting for you to suck my dick since freshman year." Or kiss his ass, or fuck off and die; he could give Hammer a list of things he was willing to sacrifice. Engineers were supposed to be precise, no wonder Hammer's little toys never worked.
