Yes too many visits to the entrance lobby over the last 2 days will cause the limp dick syndrome.
Although he has been trying hard (sic!) and fucked her many times in the last 48 hours he cannot satisfy her with his limp dick, so he has to eat her or she then has to use the vibrator.
Anyway, they do seem to be into each other and she has not use her phone very much during the sessions. They are also fucking without protection now, so maybe potential boyfriend.
