Go grab the lube and the butt plug, then lean down and grab him by his caged cock. Pull him toward toward the bed. Lay down, use some pillows to prop you up a little, and pull him so that he climbs up on top of you.
Now is a good time to tease him: pout about how you're sad that you can't play with his dick, how you'd love to slide it into your hot cunt. Tug on his nipples, rub and squeeze his balls. Lube up your fingers, start rubbing closer and closer to his asshole. If you can't reach it easily, grab his cock and pull him where you need him to move. Keep a tight grip of it, and slide a finger into his hole. Tell him how good it feels, how hot it makes you, etc.
