Vic and Matt have really gotten a lot of use out of that book so far. But they haven't tried some of the more aerobic positions, including Matt's favorite -- Pillar and the Ivy. While they're physically fit enough to try it, Matt has second thoughts about his own ability to support Vic's weight as they make love standing up. He's not the one with super strength, after all.
But Vic thinks maybe they could pull it off ... in the gym's swimming pool. The only problem? They're beginning to learn that position alone doesn't dictate which power Vic receives. Their environment during sex has something to do with it, as well.
And sex in the pool brings on a pretty fishy superpower.
