Don't particularly enjoy blowjobs and asked her not to bother, so can't speak with any authority on the owo/cim front, sorry.
You know when you're fond of a girl - or anyone for that matter - and you describe them as slim to others even when they're a little plump because, well, you like to speak well of them?
Well, Felicity isn't that kind of slim. She's genuinely slim. Her photos - such as they are - are unflattering.
Not tall. Perhaps 5' 4". 'Petite' covers her size pretty well.
