At the very same moment, he felt the hot spill of Remus’s come filling him and his orgasm throbbed on, harder still, pulsing more and more come between them. It dripped off their stomachs and between their legs as they slid together, messily falling into another kiss, not ready, quite yet, to break apart. It should have felt gross, but it didn’t somehow. Instead, it made Sirius feel closer to Remus than ever, sharing in this intimate, vulnerable act. They kissed and held each other for a long time, until Remus’s cock slid out of Sirius’s body on its own and they just breathed together, their skin cooling but still warm where they touched.
