One day, I went to a men's beauty salon to unwind, and to my surprise, the therapist was my best friend's girlfriend, Honoka! I was surprised by the unexpected turn of events, but Honoka was considerate and treated me like an adult. She may look innocent, but her massage skills are solid. Naturally, it felt amazing, but the feeling of being betrayed by my best friend made the mood between us strangely heated... I asked for a handjob and a blowjob, and I ended up ejaculating multiple times. The experience was unforgettable, so I returned to the salon. We had forbidden, erotic sex, and our relationship, now a shared secret, progressed at an accelerating pace. Without telling my best friend, I had a continuous, milking-the-cum-from-my-sperm vaginal massage, and it became hard to tell whether I was cheating or not, but I had serious sex with my girlfriend.
