Surprise Blow Job

I came home from work one day and my wife told me I should go upstairs and take a shower. She said I'll join you and I have a surprise for you. I asked where are the kids? They're at my sisters house. So I went upstairs and started to take a shower. She came in the bathroom and asked how it was going? I replied that I'm almost done so you better hurry up and get in. She then said here put this on, as she handed me a blindfold over the top of the shower curtain. She said if I put this on that she would give me a blow job. So I put on the blindfold and told her to come join me. I heard the shower curtain open and she came in and got down on her knees pulling me to her and started sucking my cock. It felt so good as she was sucking and playing with my balls. As I moaned, my cum exploded in her mouth. I threw off the blindfold and look down and it was not my wife that had given me the most incredible blowjob, but it was one of her coworkers. I said let me finger both of you. As they stood ass to ass, I reached down and fingered their pussies while I slid my cock between there asses. They began to moan louder and louder until they both came and my cum exploded on their asses.
