What have I agreed to?As 11:00 rolls by I'm already knocking on the door of their cabin. Emily is the one to open the door and looks somewhat dissatis...ied that I'm on time. "You ready?" she asks. "For what exactly?" I ask. Emily moves to the side revealing my sister in a black-laced bra with panties to match. It's a pretty magnificent sight to see and I swallow hard. "Just sit alright?" Emily commands, biting her lip in anticipation for what's going to happen. She places her hand on my chest. . such a ... slut."I knew I couldn't hold out much longer, and was looking for a chance to take a break."Aggggh," she complained, when I pulled my finger out of her ass.I stopped thrusting. "Do you want me to put it back?" Hmmm." You'll have to tell me if you want me to put it back." YES, damn it! Put it back in, PLEASE!"The tip of my finger was no sooner back in her when she took over, carelessly ramming her ass back at me with abandon. All I had to do was to hold on until I could tell that. She turned on the shower for me as I stepped inside the large stall.I just stood there as she took the shower head off it’s cradle and set it to pulsate.It was one of those shower massage set ups that came in handy at times when you wanted a more stimulating shower. I’ve even used it on clits to produce screaming orgasms. It’s pulsation mode felt like little wet fingers tapping all over my body. I put shampoo on my head and lathered it up.I soaped up my body as Connie stood by the stall door so. I surely would not be reliving such a subtly different world whilst I died.Finally, I realised that as I did seem stuck here, I would need to act as if this were a permanent arrangement or there could be big problems. I would need all the experience of my ‘old’ brain to make this work. Pondering all of this nearly caused me to miss my stop and I had to rush to the exit as the doors closed.The driver gave me a surly look. “Pay attention, young ‘un.” He grunted as he recycled the doors. As I.
