As he kissed and licked his neck, he used his free hand to trace his fingers down Subspace's chest, appreciating the bumps and valleys of scars– some intentional, some not. Medkit never would forget some of the things he witnessed Subspace do to himself, all in the name of science. It was never a pleasant sight, regardless of intention. He spent many a night patching him back up after accidents, or “accidents.” He couldn't help but wonder if he was still in the habit of… that.
Medkit moved down further, now tracing those scars with his tongue– taking his time more specifically with the two scars beneath his pectorals. Subspace's chest rose and fell rapidly, his breaths heavy and uneven. He didn't need to reach down to feel between his legs to know that this was getting him even more worked up.
