Scientifically- Your Penis!

Your Penis of course! She decided to be scientific about it.

I'm doing a survey, and i need data that is hard to find. If i could simply borrow your penis one second we can do this accurately.

I just want to stack 2 doughnuts on your cock... i mean penis. And if you can transport them on your pecker for 10 feet, I'll let you perform research on me. As she said this she pinched her nipples making them hard and visible, to show she meant buisiness.

She placed her hand out in front of his crotch jokingly, inviting him to take it out.
