Kissing was something Severus had gotten quite good at over the two months he'd shared with Regulus. Unfortunately, it was a difficult task to accomplish while trying to also simultaneously concentrate on his hand and the motion of his hips.
Severus huffed a laugh against his lover's lips. "I'm afraid I'm not very good at this."
