Holding my penis inside of her

So, when I have sex with my girlfriend, we tend to stop for a little while to have a conversation or a laugh, while my penis is inside of her.

It feels so good because I could feel her heartbeats on my penis.. It gets tighter and tighter, and it's a very good feeling.

One time, she coughed while we stopped for a little bit, and it grabbed my penis like crazy. IT was a good feeling!

Does anybody else do that with their partner? Having a little break while inside without motion??
