The combination of wine and the sedative had calmed Sara's frayed nerves, and she finally looked relaxed. She had removed the vibrating egg from her butthole and it lay on the floor by the bathtub. I picked it up and washed it thoroughly in the sink. Once I had dried it, I examined it closely. It was a very unique work of art. Made of smooth aluminium, it was very light, slightly smaller than an egg, and perfectly balanced. It had a long-life internal battery that was solar powered which never needed replacing. For this reason, there were no external ridges like most cheap anal eggs, that needed to be opened to change the battery. This made it extremely comfortable to wear for long periods of time, with no physical discomfort. It was also very easy to insert and remove. You could vary the temperature by heating it in warm water, or chilling it in the fridge or freezer. It was obviously custom made and had Japanese script on the side that I couldn't understand.
Sara had turned her head and was watching me as I examined the toy. She stared intently as if to prevent me from throwing it away. I asked her if she was planning on keeping the vibrating stimulator, and she nodded an enthusiastic affirmative. I could tell she fucking loved that sex toy and so I placed it in the bathroom drawer. She asked me to put the Apple Watch in there too, so that neither piece got lost. I shuddered again at the control Adrian had been able to exert over my wife, using stimulation as reward. Sara went to bed shortly after her bath, falling asleep within moments. I returned downstairs to do a final clean up before my bedtime.
