I live in the U.S. and I've always called them panties. I thought that knickers was a term that was more common in Great Britain and Australia. The only time I've heard the term knicker was in British and Australian porn.
Personally any of the boobs I've seen that were fake I could tell were fake. I prefer natural boobs. Most of the fake ones look like someone attached a tire pump to her nipple and forgot to take it off soon enough. Most of the time they are too round and look over inflated.
I would only consider it cheating if I wasn't invited and there were no pictures.
I absolutely love eating pussy, and will eat my lady's pussy as much as I can. I get off making her cum. It's an amazing feeling to be able to give someone else pleasure in a way they can't do themselves.
No guys don't think about having sex with every woman they know. There are only a select few I think about having sex with. It has more to do with personality and how we interact. If she is a bitch to other people, she's probably going to let that spew out on everyone around her at some point, and I want the distance to remain not spewed on.
I once had sex on a pool table in my girlfriend's basement while her parents were upstairs. At a drive in movie (Now I'm showing my age... LOL). Between two sets of railroad tracks while a train was passing through. In the bathroom of a laundromat. In the women's room at work.
Does this count?
After being married to my wife for fifteen years. All of which she denied masturbating. We were going to bed one night and when i pulled the blankets down there was an eight-inch purple vibrator and anal beads on the sheets. I could see that the vibrator had not been cleaned. She did admit that she masturbated regularly that night.
