Definitely no way to be certain. But hell, Squall's far more confident and capable in this area than Seifer had ever expected. He'd been through this song and dance over the years with others. But Squall?

Guy must be a natural or something. He groans as Squall meets him force for force, and his hips roll as he moans over the way his tongue gets sucked. The guy really was doing more than expected.

And of course, it has the expected effect on Seifer's body. An effect he has no problem grinding against Squall's body to get himself some of that wonderful and sweet friction.
