By the time it came to us leaving the beach I thought nothing about walking to the car park naked. I had been nervous being on my own with people star...ng at me the first time but that wore off as the day went on. I was feeling a bit sad when we finally drove away from there I hope Jon takes me back there one day.We put our vests back on again and drove back to San Antonio. Just on the outskirts Jon told me to put my vest on and we drove to the car hire place. Jon gave them the keys and we. The cleaner then rushed into the stall and quickly locked the door.The cleaner held me against the toilet and as she climbed on top of me, she covered my mouth so that I could not make any noise. She was breathing heavily on me as she unzipped my pants and grinded her ass on my semi erect dick. I was still in panicked mode due to her sudden actions and tried to push her aside. She used her whole body weight on me and locked lower body from moving around.She uncovered my mouth and quickly. The two sisters stood there, wide eyed, wearing neat white blouses and dark blue pleated skirts, white stockings and buckled shoes. I felt my face start to burn, spreading down the front of my body. I couldn’t imagine how much of a mess I looked like. “I told you” one of them hissed to the other. Standing there like that I couldn’t have told you which was which. Same white teeth. Same perfect faces. The other one reached forward and ran a hand along my belly slowly, saying softly “Yeah but this. However, a few moments later she handed me the dildo and said in a husky voice: "Fuck me with this." She leaned forward again, grabbed hold of her ass cheeks and I gazed again at her rosebud, which was still slightly open and wet from my saliva. That's when I noticed that the about one third of the dildo had been thoroughly lubricated with KY jelly. I took hold of the dildo right above the lubrication, where it was still dry and placed my other hand on her ass. I carefully guided the glistening.
