While visiting a household, I was informed the master hadn't returned yet and would need to wait. A cute maid led me to the dining room and served tea, but I accidentally spilled it on my lap. My clothes were soaked, and feeling responsible, the maid hurried to wipe me clean. Since even my underwear got wet, I had to let her remove my pants. As she wiped over my underwear, the bulge gradually reacted, escalating into a highly erotic situation.
