One day, for a change of pace, I went to a men's spa and was surprised to find that my best friend's girlfriend, Honoka, was the therapist... I was taken aback by this unexpected turn of events, but Honoka was considerate and handled the situation maturely. Despite her clear appearance, she possessed solid massage skills. Naturally, the relaxation was top-notch, but the sense of transgression, as if betraying my best friend, heightened the atmosphere between us... I repeatedly climaxed through the back options of handjobs and blowjobs that I requested. That experience was unforgettable, leading me to revisit the shop. We engaged in forbidden and incredibly erotic sex, and sharing this secret accelerated the progression of our relationship. In serious sex with her, where I kept it a secret from my best friend, through intense internal massages and continuous ejaculations, it became unclear whether it was cheating or not.
