I've been there a few times, you can strike lucky on occasion.
Most recently I saw a Helen, twice. First time we agreed HJ, then she suggested she sit between my legs, and spend some time on it, I was to tell her if I came close to coming, then she'd slow down. Of course I agreed. Maybe 20/25 minutes, very good hand job, letting me dictate the pace, when I asked to finish she tightened her grip and quickened the pace. Excellent, so I gave her an extra £10, £30 tip in total.
They have a three/four week rota at this shop, so I checked when she was working again and paid a visit.
There were two 'girls' working on this second visit, I agreed quite early on to go for B2B this time, but the clothes didn't come off until the second half and then it seemed reluctantly. I asked her to give me a repeat long extended HJ again, expecting her to remain nude, but she told me five minutes in that she needed to get dressed, as there were two girls working. Didn't make sense to me so I told her I'd prefer she remained nude, things then got a little heated, her repeating that because there were two girls she couldn't stay nude and give me the same service as the previous visit.
This all rather spoiled the moment, so I stood up, got dressed, gave her a £10 tip and left. Had to go for another 'massage' the next day

Shame, as I said I'd had a few good sessions there, but this put me off.
