Get your girl to play with your balls while you are in the act. Let her reach down and massage them. (If it is physically feasible.)
Also, around the choda area is a very sensitive spot. By getting her (or you) to push, knead and massage it, you will receive great pleasure, and generally a quicker orgasm (in your case, A orgasm.)
"I still find each day too short for all the thoughts I want to think, all the walks I want to take, all the books I want to read, and all the friends I want to see."
