Eugene, as much as he tried, couldn't remember what his first kiss with Arthur was like all that time ago. He was a bit drunk at that time, and still had leftover adrenaline from beating up some drunkards. It was fuzzy, and mostly lustful.
But he remembered Arthur to be quite aggressive, perhaps also from the adrenaline of watching Eugene beating up the drunkards. That, or impatient.
This time, the alpha was also agitated, pushing Eugene further into the alley until his back was flush against the wall. A pair of big hands held his waist and the back of his hand possessively, as possessive as the lips crashing into his.
It wasn't a kiss that cared about technique. It was all emotions and feelings, when the body moved before the mind, when instinct was all that was left between two bated breaths.
