I was away with my Master, staying at a nudist campground in a caravan. The weather was a bit dull one day so Master decided we should have a session. I was lying naked and blindfolded on the bed ...and waited. Some time later I heard a vehicle approach and someone knocked on the door. I heard quiet voices and had no idea who was there or what was in store. Next I felt a warm tongue trace a path up my leg to my eagerly awaiting pussy. I didn't know if it was a male or female as I was tantalised with a tongue and soft hands massaging my breasts. I was finally allowed to touch when Master joined in and found a very smooth an hard cock. Still blindfolded I climber on top and started to ride...suddenly I was grabbed from behind and another cock was plunged into my ass, it was my Master. I was full to the brim with delicious cocks. The feeling was so intense, my first double penetration and the sensations were almost unbearable. I came explosively and collapsed back onto the bed. I was finally allowed to remove the blindfold and found a lovely young Countdown delivery driver was who had come to call! I hope that his deliveries weren't too late as a result of his detour.
