It wasn't as tough Sulu had any particular preference, not when it came to things like this, and he was enjoying the position they were in just as much as Ianto, so there was no real reason to turn Ianto down there. Truthfully, he was really, really up for staying this way, especially if it involved him pressed against Ianto like this, and really, what better use for a couch was there?

He moved his hands down to one of Ianto's, pulling his hand away from his side in order to wrap his fingers around the bottle he'd just dug out of Ianto's drawer. With both hands free now, he reached up to pull Ianto's head away from his shoulder; as much as he liked Ianto flustered, he liked being able to make eye-contact with him more. "I wouldn't mind at all." He paused for a moment, then added, "Wait... Do we have to use a condom?"
