Ok so I have had quite a few people ask and also got curious myself. So my friends whom I have known for some time, the pic I posted "Wife and Cuckold Husband". We had an in-depth conversation after I had confronted them when I discovered their lifestyle. Told me all kinds of details, but one particular which will be the subject here was when she was fucked by 2 different guys (2 seperate occasions) with 10 inch cocks. Told me about how the second guy it took 15 or so minutes to work it in and another 20-30 minutes of working it before she was able to finally take him balls deep. Questions had been asked and my own curiosity got me, what would that look like and how deep in her is that big of a cock? So I took one of her pics of a full frontal to find out. She is 5'2", which is 62". So I laid out a grid with 62 evenly spaced boxes. Measured from where The beginning of her pussy is up 10 marks. Drew a line to represent the accuracy of the measurements. And this photo is what I got. With that being said, AM I looking and doing this correctly to figure it out? Looks like a 10 in cock, once all the way in her balls deep would be up near her diaphragm area. She got her pussy stretched that far in to her guts if I am correct about it. What do you think? Am I correct? Here is the grid system I used to measure.

no, your cock (or any) does not go straight up !

We cuck also. I have a 4” dick hard and have had threesomes four different times with guys that were8” to 9 1/2”. I always get naked and she measures both of us hard so I can be humiliated. I further get humiliated after he has fucked her for a bit and then she has me stick my little dick in her so she can embarrass and humiliate me more in front of him. I usually start cumming really quick. More embarrassment. She always loves the big ducks fucking her.
