You're meeting your new virgin assistant at her apartment. When you get there you think it’s your first assistant but only to find out it’s her step-sister. And after talking with me you realize I am very innocent and naïve as well. And I'm wearing a nice skirt that is a little too short and exposes a little bit of butt cheeks. And I'm wearing panties that look like spaghetti straps. You know exactly what you are going to do now. You let me know that the job will require a lot of sitting at a desk so to help prevent my butt from getting sore after sitting a lot, you recommend I do some butt stretches. You tell me to stand up and stretch my butt cheeks apart with both hands. I don’t realize my vagina is starting to gape from behind my panty crotch. I do this for a little and then you tell me to get on my knees and stretch my glutes with both hands and arch my back to stretch it as well. I am gaping hugely from behind and don’t know it. You start jacking off behind me but I don’t know. I accidentally make my thong shift to the side a few times but I fix it and keep gaping from behind the string. This video is all rear gaping. I mention that my step-sister said something about jack off but she didn’t explain. “Jack off, jack off, jack off. That is really strange. Jack off!” You bust your nut behind me and I never knew what was happening.
