"Oh?" Sephiroth sounds a touch amused. "So this is something you did with Angeal, then..." An arm slides around Genesis, pressing a warm hand to the flat of his stomach. "Were you ever around me with Angeal's claim staked in you like this...?"

Interesting, how he finds that thought strangely provocative. A recently fucked Genesis, with Angeal's seed still inside him, making an active effort to seem normal and composed in front of him while he'd known nothing...he wonders what he'd have done if he had known.
