Watching Natasha coming apart is fascinating. The last time they were anywhere close to this situation, she was much younger and while she was already an accomplished and talented student, Natasha wasn't the Black Widow yet, and was still very much a young woman with her first lover. Now to see the cynical, toughened Natasha he's come to know let herself loose with them is kind of amazing.

James' introspection ends quickly at Sara's question. By the time he looks down again, Natasha's hand is flying over his cock and her mouth is wide open and inviting. "I wasn't going to," he says heatedly, "but since you asked so nicely..."

He takes a breath and lets go of anything he was using to hold back. A few more pumps of Natasha's hand and then he's growling loudly, legs almost buckling under him as he starts to spurt onto her tongue.
