The biggest I saw my ex-wife take was a bit over 11" and as thick as a Pepsi can. She measured it in front of me and she took him right to the nuts 1st stroke. She told me it hurt like hell until the 1st orgasm hit her, then she was all in for the fucking she got.
Her first bbc was the biggest, over 10” and very thick, thankfully he knew how to refrain from forsing it all the way in, 5’2” and 105 lbs, she is not as deep as some bbw’s we know! She took as much as she could like a champ and loved it.
No it isn't. Well, that day he was acting in that capacity I suppose but no he is not her regular lover is what I think you are asking. This was a one time thing. Back then we really had no idea how we were going to get started. A friend of hers offered to have my wife join them in a threesome to kind of break the monogamy ice if you will. Had this worked out it would have been much simpler as they live close and he is dating my wife's friend so no attachment issue.
