A few weekends ago I had to take over boat north to another marina, I had kept an eye on the weather, picked the weekend that we would set out.I rang around some friends thinking a good opportunity to catch up and spend some hours having lots of fun at sea,as the boat is very comfy for this type of entertaining..but alas no takers.So just the wife and I head out of the heads and turn north with the sun shining and flat seas.On the flybridge it was very warm in the sun and the wife was complaining that she had only bought cloths for the cold,I didnt take a lot of notice of the comment and went down stairs to tidy up ,on returning to the fly bridge there was my lovely wife sitting at the helm with not a stich on..so not to make to much of a fuss just came and made small talk as to the lovely warm sun and how beautiful it was, but just perving on her naked body was getting me very hard..Trying to prolong any action I moved to stand behind the helm chair and slowly started to caress her nipples,which started to respond by standing up nicely and then she slowly moved her hand behind and up my shorts to find my member very hard and ready, so after lots of teasing it was time and I lost my cloths and moved around and she stood in front of me while i now sat on the chair and massage her every parts while we still steamed full ahead.She then lowered herself slowly onto my aching cock as she still had two hands on the wheel i had two hands free probing and teasing her clit as she slid ever so slowly to empale herself fully on me.We had just past the lion island as we started to work ourseleves into a rythem that suited the roll of the boat and still soaking up the geogeous sun on our bodies...by now i had my fingers up her as well as my cock and she was riding everything with full power,every rise saw her lovely cum dripping over my rock hard cock and balls..I lost count of the time she came on me and finally I couldnt hold any longer and blew loads into her fantastic pussy..as we sat spent and sweaty i looked across to the shoreline and wondered wether any lucky bugger had a set of binoculars and witnessed a great cruising fuck..i finally took my phone snapped a pic of the wife laying spent at the helm and sent it to my mate with a note ..not to miss the next cruise north!
