It was his first time. Not hers though, she had told him. Asami had been so gentle and understanding of his awkwardness, holding him, kissing him, telling him exactly what to do; what felt good and what didn't. She was so caring. And he was inside her now and all he could feel was wet, tight heat. He was blinded with pleasure and could do nothing more than bury his face in her neck and moan while she said his name over and over again.
"Mako."
He stayed still for a few seconds. Everything felt so good, he couldn't chance moving and ending it all too quickly. He breathed deeply and moved slowly, groaning while pulling back to look at her. She was lying on the bed; her hair all splayed around her head in beautiful curly waves, her skin so much like porcelain. She looked like an angel. For a few minutes as he moved inside her he could do nothing more than be awed by her beauty. But then she's moaning and moving her hips slightly again his. Breathtaking pleasure. He's reaching that inevitable place of no turning back and he moans, burying his face in her neck once more. And suddenly he's not with Asami anymore, suddenly he's kissing Korra outside the arena, and her lips are so soft and everything about it feels so right. As he looks back at Asami she's suddenly not there anymore, instead it's Korra looking at him; her dark skin glistening with sweat, her bright blue eyes staring at him with pleasure. His hips buck and he's thrusting harder, wanting to please her as much as he can. He moves faster and she makes the most wonderful noises. He's close, so unbelievably close, and as the blinding pleasure takes over him and he spills himself inside her, he can only moan one thing:
"Korra…"
He falls on top, breathing heavily, and immediately notices what has happened. The girl beneath him has changed, it's not Korra it's Asami. Asami. She's completely still, her eyes wide and filled with tears staring up at him. There's nothing he can do but freeze and stare back wide eyed. What has he done? He withdraws from her, scrambling backwards quickly on the bed.
"Asami…" he says, "I'm sorry – I don't – "
"No." she answers, "Don't say anything."
She turns on her side, wrapping herself up in the sheet.
"Asami, please. I just –"
"No. I understand everything now." She whispers, "Everything."
