I say,
If you haven't had a threesome before, take 3 cialis and do the hot chick first, then kick her out and do the threesome. Business meeting. That's a good excuse. She'll say "Call me when you're finished!"
Otherwise:
Piss in the 2 above average chicks' mouths, then get a double Blow Job where they fight for your sperm, slap their asses and kick them out after you cum all over them (business meeting), then take a bath while the hot one comes over.
It's like eating carpaccio before eating a steak. The steak will appreciate your whetted appetite and increased decisiveness.
