I took a job at a female-exclusive sensual spa to pay for tuition. The pay was good, but it was essentially a "sex trade," so I didn't want anyone to find out. I had a rule for myself to avoid actual intercourse. Then, the neighbor's wife, whom I always helped out, came in as a client. I tried to treat her discreetly, but it was impossible to hide with just a mask. She demanded "real intercourse" on the condition of keeping it a secret, and I had no choice but to agree.
