'Well here it is... I hope that you can get an idea of how I made this device and how much Master and I thoroughly enjoy using them. '

What a delightful photo. I am sure that you and your master will have many enjoyable sessions with the new contraption. It looks like a 5 cc syringe. You might look in a large animal supply store or catalog to find other sizes. I would recomend a 10 or 20 cc syringe judging from the size of your areola. More could be inhaled by the barrel and a greate extension could be achieved. If you used some vaseline or ky then you will have a better seal and might actually be able to suspend weights with these.
