Much tried to say "Oh fuck" as he kissed her, but no one was that good at multitasking when her body - oh his fucking life her body - was taking him inside her. Any last traces of meaningful thought were squeezed out of his mind by the mindblowing relief of how good she felt. Every shitty thing he'd felt today was made right, every trace of guilt or self-loathing or her-loathing was forgotten because the next thrust of his dick into her was all that mattered, was - for all he could see right now - all that would ever matter again.
He couldn't possible last very long, but what did that matter when every single stroke was mindbending bliss?
