This is a 4K video requested by a user who is a master of the art of tit bondage. I am so delighted to make these kinds of videos because I like bondage and it challenges me to do it. I take these kinds of requests as a personal challenge, so I hope you like it. I am open to feedback so that I can improve and grow in this art. It's the first one we've done during my breastfeeding, so we agreed on 3 hours without breastfeeding before starting, but I think next time we should wait many more hours for a better result. We used 5 rubber bands for the nipples, 4 zip ties for each breast, and 3 shoelaces for each breast, a spoon, and a Hitachi vibrator.
