OMG - Full injection!

My girlfriend's boyfriend surprised me in the shower! He was so cheeky and took full advantage of the fact that she wasn't at home. At first I didn't know how to react, he just stood in the bathroom and took his clothes off! That made me really hot and he really fucked me in the shower! His girlfriend could have come at any time. But it was really intense that he held me tight and squirted everything in my pussy with sheer lust. I can only hope that nothing happened! Would you have been so bold?
