Sex Clubs In and Around Cardiff

Been on SH for over 7 years and just found out my G/Friend- Fuckbuddy of 10 years would like to go to a proper sex club, not a lap dancing club but a swingers club, I've checked online but get the usual Clubs, was wondering if anybody out in the SH world new of any in the area that were a bit more risque, she also want's to try a bit of "Light" bondage, so any help would be you need dates then it would be any time in April, probably a mid-week. Thanks. D
