Sirius ran his hand upward, tracing his fingers just underneath the elastic waistband of Remus's shorts and feeling the muscles of Remus’s stomach flutter as he teased along the bare skin. Remus was so sensitive, so responsive, so hungry for every single touch, and Sirius wanted to put his hands and tongue and mouth all over every inch of him. He reached into Remus’s shorts and took his long length into his hand, gently caressing and pumping while he lavished Remus’s lips with languid kisses. He pressed one more kiss to Remus’s neck before leaning down to speak directly to Remus’s shirt.
