My father in law has a huge cock. He is very thick, probably a fosters can thickness but I might say thicker and he is about 8-9 inches. I have seen it in use and OMG he has stretched those tight pussies. He also has a massive load, so much cum, just gushes everywhere. It's very hot watching him at work.
Can't wait to hear about what happens with your GF's husband and you and your daughter
