i wanted to collapse forward , but his breathing was harsh and panting , his body bucking , straining for release , and i was caught up in the drawing out of the pleasure , each thrash of his body driving him deeper inside me , my muscles trembling and tense and ready for the explosion , the implosion ... my hands braced on his stomach , propping me up , i rolled my h*ps onto his , ignoring his ever more vocal groans of need .
