Ass - the concept of all significant, because the ass is different. For example, this hubby is just crazy about a luxurious blowjob of a young woman and just drags herself from her slender elastic ass and at the first opportunity inserts a thick erect penis into her pussy. But this is one thing, but if he is so excited during sex that he does not have time to take out the penis and ends up inside her, then this is a completely different matter.
