Pathetic morning fuck

This morning started like a lot of mornings with me and my wife cuddling. As I ran my hands over her soft warm body I noticed that she wasn't wearing any panties, meaning that she was probably very horny and might even want to ride my pathetic premature dick. Obviously the thought of this instantly made me rock hard and desperately throbbing. She turned to lay on her back and spread her legs open. I gently caressed her eager pussy while she moaned with overwhelming pleasure. She asked me if I thought I could handle fucking her for a change or if I just wanted to grind on her until I came in my boxers again. It stung a little but in a good way as she almost never makes fun of my pitiful lack of stamina. I told her that I would love to fuck her but it obviously wouldn't last very long. She said it's fine as long as she still gets to cum one way or another. I buried my face between her legs and gently licked her pussy with my finger inside her. It only took a couple minutes before she moaned out that she was cumming and her pussy was squeezing my finger. After she finished cumming she asked if she could get on top. Whenever she asks to be on top it means she really wants to fuck because it's my "longest" lasting position. She got on top and slid down and surprisingly it wasn't too overwhelming. I thought I might actually be able to last awhile. Then about 45 seconds in with absolutely no warning or build-up it flipped and I could feel myself ready to cum. I whined out that I was gonna cum and she started riding harder until I exploded. She stayed on top of me and kept riding until my useless cock finally went completely limp.
