It's a pleasure to see Marius like this, all caught up in physical pleasure, all brought on by the workings of a simple touch. It's glorious to watch Marius writing beneath him, body jerking to him on instinct as he reaches up for Rat, leaves to sunlight.

Moving quickly, Rat joins Marius for the kiss, fingers still working at him intently. The feel of Marius' body along his is too much and Rat is only barely aware of how his own instincts are winning out as he rubs a hand against himself, his own fingers nudging inward, hands moving in time. One against Marius, one for himself.

All of it bracketed by Marius' kisses.
