Something that has always turned me on and wanting to do when my wife is sit in the living room on the couch topless with her small breasts exposed is to tightly tie them up. We had done breast bondage before but I wanted her to stay with her small breasts tightly tied up for as long as she could stand it and have them turning a light shade of purple.
So Friday night while we were watching a movie I asked her if she would let me tie her breasts up for some light bondage. Since she was already topless and her small 32b breasts were in full view. She agreed to it and I didn't use rope but had some soft red yarn on hand. With her sitting there I measured out two 6 feet links of red yarn to be used to tie up each one of her small breast. I set one aside and with the other made a slip knot at the center. When I was ready I asked her to lean forward letting her breasts hang down for me. With her in position I slip her small breast into the yarn knot and gently pulled the yarn tight as close to her rib cage as possible and pulled it tightly around her dangling small breast. Then I had her sit up and started wrapping the yarn around the base of her small breast. When I was done with her first breast it was the size of a small orange nice, round, and firm.
Because her breast was tightly tied it was no longer looked saggy and her medium size puffy areolas were streached out flat no longer puffy looking about the size if a round coster with a small 1/2 inch eraser bump sticking out which was her nipple. When I gave her breasts a squeeze it still felt soft like before but morr firmer from being tightly tied up.
