How has your book buying/reading been?

I find that when a sex scene just doesn't make sense, I get irritated and want to drop the book immediately. One recently was H and h were somewhere public, she was seated (no mention of slouching or providing access to certain areas) wearing jeans and he somehow managed to insert fingers and happily pump away until she finished. And no one noticed. I guess she was wearing super baggy jeans and his fingers are kind of magical? I'm sitting at the computer in stretchy pants and there is no way some large hand and arm is going to somehow access my body to that extent without creating some noticeable movement that others would notice. Not to mention she was silent through the whole thing. That is either really impressive or actually really not. I don't have patience for stupid scenarios anymore.
