She did the same thing when I saw her, thought it was strange a first, got into it after the second round.During a recent bj, the woman took a mouthfull of hot water from the sink faucet, then she sucked my testicles one at a time into her mouth, then back to bj with her mouth still full of the hot water... It felt really good.
Her name is Yuki at Tiger Spa, I did post a brief review about her in the "Tiger" thread.
