So, on one of my ‘study sessions’ with Dr McPhail, I was intrigued when he said that it was a special day, and he had something different in mind....He had me take my shoes off, then took my hand and led me to a door to the cupboard under the stairs. I had never seen it opened, so I was surprised to discover stairs leading downward, to a basement. “I didn’t know you have a basement,” I said.“I don’t use it very often. Come along,” and he led me behind him down the wooden stairs. I was a little. I’m just a bit conflicted about it. It takes a certain amount of effort to suppress a smile or a giggle as she strains to not make a sound. Her front teeth are pressing harder, sinking deeper into her bottom lip. I'm a little afraid she'll hurt herself, but what else is there to do?An idea sneaks slowly into my brain, and it percolates for a few minutes. In my bag, there's a jewel. Something special. Close to my heart. A miracle of mechanical engineering. Powerful, smooth, and rigged for silent. The one in her mouth came, and after a few spurts pulled out to cum all over her face. A guy nearby had been jerking himself off, and stepped up to cum on her too. Soon she was getting very sticky and gooey.The guys just kept cumming. She lost track of how many dicks she sucked, but at one point had 3 going at once. She would just suck one for a few, turn her head and suck another, and then the other. The guys were jerking off in between sucking, so some came in her mouth, some on her face, and. All times and durations would either be pre-planned or booked, or byshort notice request via text or telephone. Likewise, all arrivals anddepartures for such 'service' would be with me fully en femme and theaddition of overnight requests would also be expected as and whenrequired.That made me take a gulp! So far I had always been permitted to changeinto 'Chrissie' upon arrival, so this new development, although doable,would put me on edge!To support her 'staying over' policy, she backed that up.
