Not saying it's real but a third breast there is rather more likely than a third breast in the middle like in other fake vids. I have a vestigal third nipple myself, as does my father. I suspect there are women out there with a third boob below one of the others. Maybe the people who faked this were striving to be a little more convincing. The cock isn't that unbelievable though if it was real, why didn't they show it going in or coming out? If it was a fake helmet the ejaculation was pretty well done.
I have an ex with an ex-boyfriend who sounds like he had a cock head of similar proportions. She reckoned she couldn't get close to getting her fingers round the shaft and the head dwarfed the shaft. She couldn't get it in her mouth. Unfortunately it was too painful to get his foreskin over it while erect and they were never able to fuck. She couldn't talk him into getting circumcised either.
