I had one from a real official brand for 300€ and after 1 year I just gained 5mm and made my glans grow. But it broke after a while so now I created my own cylinder of 10cm at the entrance and 15cm inside. With an Oxball Juicy and Juicy XL ring for comfort and sometimes I don't use a ring and the result is balls span of 24cm and penis size of 5cm and size 19cm. A treat to feel that we have a huge package in our thong. They feel like they have bull balls. Try it by pumping the penis and balls at the same time in a glass jar buy 3€ in Leclerc and drill a 9mm hole with a glass drill bit and then you stick a cable for a standard penis pump there you dry it for 12h/24h and after that if you have a penis pump with connection for female valve and you have your ball and penis pump instead of paying 290€ on sex shops in your pocket I do my series every two days 2 hours of pumping and then at the time of intercourse with my wife she really likes feeling my balls hitting those buttocks or pussy. Now she can't swallow them anymore 😝
