Went for the 4 handed massage on Thursday after reading this. First time with 4 hands and it is certainly an amazing experience!
One of the ladies is an older (40s) Chinese lady and a younger (20s) English girl. Nothing extra offered and I didn't ask, however, the older lady had her hand up my boxers and brushed my balls several times so I think extras may be available with her on her own. Didn't get that impression from the English girl which is disappointing as she was very attractive.
The place is a proper beauty Salon place in Whitley Bay with what appears to be only 1 treatment room. I'll be back to see her on her own and see what's available and also for the 4handed massage as it was a great feeling
