I know she's a professional and I know this was professionally produced, but that's about as real as it gets...
I re-watched a bit of this just now. Again while jumping around the video. Yes, about as real as it gets.
A minute I happened upon and thoroughly enjoyed watching
39:48 her mouth opening,
39:52 quick exhale and moan
39:59 the breathless laugh she emits
40:03 "fuck", the light sheen of sweat on her upper lip
40:10 toe curling
40:13 the smile on her face as she brings the dildo to her face "Wooo"
40:17 where she wants to begin again
40:23 when she lips her upper lip
40:45 to 40:52 her toes wiggling
Dang ST, I'm going to woo you for this.
