I knew my brother had been spying on me getting changed. I left the door slightly open on purpose, just to see if he would. He thought I couldn't see him in the crack of the door. That's why, when we went on holiday and had the villa pool to ourselves, I asked him to put the lotion on for me. I was lying on my stomach and I knew he'd watched me get out of the pool. I took a long time drying off on purpose, the sunglasses he was wearing didn't stop me from knowing he was looking at my hard nipples poking through my bikini top. I made a great show of getting onto the sunbed and then casually threw the bottle at him, asking him to do my back. He tried to hide it, but I could see the bulge in his trunks when he sat up and I had to turn my head away to hide my smile.
The cream was freezing cold against my skin, but I reached around and unfastened the string at the back of my bikini so he could do my whole back. Then I unfastened the string at my neck. "I don't want tan lines! Make sure you do it properly, I don't want to burn so no missing bits please," I said. I could feel his hands shaking as he massaged the cream into my skin. "You need to do the whole of my back please John, that includes the sides!" I heard his breathing change and smiled again. As his strong hands moved around to my sides, I shifted myself up ever so slightly so that both hands came into contact with the sides of my breasts. He froze. "Carry on!" I said, "What's wrong with you?"
