“Ohh, Dima!” Katya cried, wrapping her legs and arms around him, holding him tight as their bodies pressed as hard as they could against one another – him shooting his energy into her, her surrendering to it, to the shocking waves of pleasure. They groaned and bucked, white light filling their minds, white heat overtaking them. Katya felt as if it would never end, as multi-colored stars burst into being in her vision, even though her eyes were closed. 
But it did, slowly, slowly receding. The two spent, exhausted lovers floated up from the depths of their little death to consciousness, knowing where they were and what they were doing. They had pressed their faces hard against the other as they came, and now Dima lifted his head, looking at Katya with supremely satisfied eyes. 
“That was wonderful, darling,” he sighed. Katya just smiled, feeling too much like jelly to move or even reply. Dima drew a deep breath. “We should start getting back,” he said, tickling her nose with a finger, then kissing her. “You seduced me into staying, you naughty girl, but it's already quite dark.” 
In the next few moments, several things happened so fast that Katya couldn't comprehend it all in her post-orgasmic state. A rustle of the tall grass and reeds around them, a short, sharp whistle, dark shapes moving. Dima's cry as he was pulled roughly off of her, and then Katya herself being captured by two strong pairs of hands grabbing hold of her arms. 
“No!” she cried, understanding too late what was going on. Watching in horror as Dima struggled with the dark shapes. 
One of them came towards her, his dark face, framed by the traditional black felt hat and long, curly black hair, drawing closer to hers. His eyes were like the darkest coal, and his skin was a deep, sun-burnt olive color. A black beard covered the bottom of his face. He looked into her eyes, and she fell silent, intimidated by his silent, powerful presence. For a long, drawn-out minute, the silence was deafening and his stare bored into her eyes and through her. She felt naked in front of him. Which, she realized with a cold chill, she was. But he pierced her more than that, and finally, Katya mustered up the energy to close her eyes and turn her head away. She heard the Tatar – by now, she knew that he must be the leader of this raiding party – laugh, a full laugh from his belly. 
“Looks like we've caught you, little mockingbird,” he told her – surprisingly, in her tongue. “You and your little fairy of a man. He could screw you, but he couldn't protect you!”
