When they both slowly calmed down, still trembling and hot but not that frantic anymore, Clint gave in to the weakness in his knees finally. Still holding Natasha tightly against him, he somehow made it to lay down on his side, staying inside of her to not risk hurting her after all with a rash movement.
Instead he pulled her close to his chest and buried his face in her damp hair, trying to get the shivers shaking him under control, with little success.
He felt completely drained, for the moment at least, a beautiful nothing on his mind but the scent of her body and her lust and the perfect way they fit together. His arm hugging her close was gently draped across her chest, fingertips caressing her shoulder and neck, and he smiled when he could still feel her pulse race.

"Jesus, Nat... Wow."

Okay, so coherent speeching was still on holiday. But he thought she would still have a pretty good idea how very much he had enjoyed this. He pressed his face against her neck, still smiling, just felt and listened to her breathing. He let the last of their lust wash over them while the natural movements of her muscles and his flattening erection slowly guided him outside of her tight hotness.
Another blissed out sigh escaped his lips. Yep, definitely sensitive but so much worth it. Hopefully she felt the same.

"You good, Tash'? I didn't hurt you, did I? You've had me pretty far gone there in the end."
