Tifa's trying to hold back. It feels amazing, and she doesn't want it to end, but Nami's words send a whole other heat through her.

"N-Nami," she whispers, whole body trembling as she tries not to buck or crush Nami in her legs. "You're -- you're --" She gasps, eyes wide and her back arched, body heaving and shuddering as she forgets to breathe. She's never come this hard, her vision going black and white an an electric heat blossoms and bursts.

Finally she slumps down, panting and woozy, gently petting Nami's hair. "So did you," she says, lame and breathless, her eyes wide as she looks down at the other woman.
