The first thing we had to do to get you set for your little "journey" was to get you situated comfortably on the bed. I had you lie on your back and spread you arms and legs out spread eagle so I could secure them to the four corners of the bed. When I finished I propped your head up slightly with a nice soft pillow. I asked if you were comfortable and you said yes. We were ready to begin.
"Now my dear before we get into the serious part of this activity" I said, "We must precondition those sweet cute nipples of yours" You had no idea what I had in mind. I continued... "What I plan to do is use these nice little plastic film canisters you brought (you know, the ones from those 2 rolls of pictures you sent me of yourself!) and get those nipples to stand up as much as they possibly can. You see while I was tying you to the bed, these canisters were soaking in hot water in the sink. They are now very pliable and can be twisted to new shapes." I then put some KY jelly around your nipples in a ring about the diameter of the canisters. I also put some KY on the inside of the canister. I then squeezed the middle of the canisters such that the cylinder looked like it was crushed at the center. I then proceeded to place each canister on your breasts with the nipple in the center of the circle. When I released the canister you immediately felt the tug of the suction from the canister as it tried to regain its cylindrical shape.
"You see my dear as the canisters cool down, the walls of the cylinder will want to revert to their original shape. In addition, as the air temperature in the cylinder cools, the pressure inside also decreases. Since the KY jelly formed a perfect seal between your breasts and the canisters, both of these factors will cause those nipples to be sucked further and further into the canister! And every passing minutes will cause those nipples to grow."
You could immediately feel what I was talking about as the canisters began their magic. It was a quite pleasant sensation...more than pleasant...like me sucking you're your nipples but without the tugging. It was very pleasurable and you immediately began to get excited. And since you had bought Fuji film (they use clear canisters) you could see your nipples rise before your very eyes!
I then proceeded to put a blindfold over your eyes. From this point on I wanted your mind to be the primary driver of your excitement...and of course some highly erotic titillating breast and nipple play. I told you I was going to take a shower and would be back in about 15-20 minutes. I left you alone with your thoughts in the blackness...with a constantly increasing suction on your nipples.
When I returned I could see that you were really enjoying those canisters on your breasts. Joy was already very wet (hard to hide when you're spread eagle – hee hee) and there seemed to be a soft purring sound coming from your lips. You didn't notice that I had come back into the room.
