Get down from where you were and take the dildos away from your mouth and your ass. Also, grab a third dildo, one that it hopefully larger than the other two. Get on your knees in the slut position.
For the next couple of minutes, you are to give blowjobs to each of the three dildos, moving back and forth between them. If you can, go ahead and stick two or three in your mouth at the same time.
Your goal should be to lube each of the dildos well, as you know they will soon be back in your ass.
