With Bia....... I get the impression that she isn't keen on multiple rounds (judging by her profile text) and with me being fairly young and gym fit, going 3/4 rounds in an hour (provided she's fit as fuck) is no problem. Now only issue is if she'll allow it.....
She looks fairly gym fit.... but if she's bonked 10 punters that day before you get there you're probably screwed whoever you see.
Wouldn't enquiring with her pre-appointment be the way to go?
If this is the text your referring to:
Ps:
1. If you are looking for a fucking session (not interaction, just sex) PLEASE DO NOT call me. Do not call me asking how many times you have because with me you woul have a session where we gonna relax, enjoy NATURALLY!
I took it a bit negatively at first, but its directed more to pre and post sex as she does like to interact (basically suck the fluffys in or fluff up the punters that don't know they're fluffys yet.....

), during the action itself she's like any other decent prossie.
