Well, by now you know what happened with Aunty Sue, Shelly and myself on our little harbor outing. The weather turned nasty later that day and I had to take the yacht back to the mooring, with two rather bedraggled (but still very sexy) woman on board.
We all got drenched on the trip back, one of Sydney's famous 'Southerly busters' came up, wind, rain and cold (well still 25 degrees C) weather came up, and we all packed up, piled in the care and Aunty Sue drove us home. Shelly and I sat in the back seat, trying to keep warm, it's amazing the ways a very horny sister can keep you warm, Aunty Sue (she still insists that we call her Aunty Sue, rather than Sue) could hardly keep her eyes on the road. Shelly was alternately rubbing my colder part (well I told her cock was cold) and pushing her tits and pussy against me. We both came several times during the drive home. I can still taste the delicious taste of her juices.
As we came around the corner to our place, Aunty Sue warned us that our parents would be home in a few days, and that maybe we should all 'cool it' for a while. Shelly looked at me with those sexy eyes, as if to say 'not a hope', we both said 'yes Aunty Sue, what ever you want'.
We pulled into the drive, and parked the car. We all piled our of the car, with Aunty Sue saying 'I get the shower first', Shelly and I looked at each other and grinned. We let her get into the shower while we unpacked the car, put things away and had a little 'brother and sister fun'. We then crept up the stairs and could hear the shower running. Shelly looked at me and told me to strip. My cock was hard to start with, but with the sight of my sexy sister stripping beside me, got harder than rock!.
