When we were living in the New England and the weather was cold so I took advantage of it. On evening my wife asked me to go shopping with her so I told her yes under these conditions she would go braless with her small breasts and have to wear a sweater which would let me pull her long light brown nipples through the knitting holes of her white sweater. She agreed to my terms. So I went to my tool box and get two small O-rings to place on her nipples. I told her to get topless and got out nipple suckers and put a small amount of lotion on each nipple. I wanted to stretch them out about an inch long. I slid the O-rings over the nipple suckers then placed it on one her nipples making sure it had a good seal. I started twisting the nipple sucker and watched as her light brown nipple was sucked into the tube. Her nipple was clearly stretched out a full inch that is when I slide the O-ring off the tube and onto her nipple. I released the suction and pulled the tube off her long nipple. I repeated the process on her other nipple with the same result.
With the O-rings on both of her nipples I knew they would remain long and hard until the O-rings were removed. She then put on her sweater and I pulled her inch long light brown nipples through the sweater holes so they were visible and poke out about three quarter of an inch. So off to the mall we went for fun and games.
