First Time - Surprise Shemale

I could feel her cock bashing against my prostate and my cock was dribbling pre-cum like mad. Then I started to feel the welling up of spunk, the gradual rise of semen and cum juice. That familiar feeling when you know you're on your way to orgasm. Only this time it was different. It started at my toes, up my calves, my thighs, right through my group, up my belly, mid-riff, chest, shoulders and finally head. My eyes were bulging out of my head, my whole body was screaming out and as I looked into her eyes she knew what was going to happen. I panted out "I'm... going... to..." and then it happened.
I came.
I didn't just have 'an orgasm' my whole body, my sloppy wet, well fucked asshole, my raging cock all exploded and shook as semen shot up my chest. As her cock pounded against my prostate and each shot of cum and each gasp of breath hit me, well... I'd never felt anything like it. I was most probably shouting/screaming or moaning, VERY loudly as she slowed down the pace as my orgasm subsided. I lay there spent and she said "I don't need to ask if you enjoyed that" as she pulled off her condom. "Fuck" I exclaimed, panting for breath as she moved over to a nearby sink to wash her cock. Once I re-gained enough composure, she beckoned me over to wash my cock and well lubed and now looser ass hole. I stood and looked at her like I was a zombie, totally speechless. She giggled and asked me if she'd like me to invite her genetic girlfriend in for some more fun. Now if she had asked me that to start with I would have jumped at the chance, but I was spent, physically and financially too (my wallet was empty). I declined and started to get dressed and I tried to mumble my thanks. As I left she pecked me on the cheek and said "come back soon".
I never did see her again, and i've never had such an amazing orgasm either.
I keep trying though :)
