Have you ever masturbated on the terrace/balcony? I love it! You hear passers or cars driving by and then you always imagine how they would react if they only knew what was happening upstairs on the terrace. I get extremely excited by the thought of masturbating like that. So I don't even bother sunbathing for long and move my fingers straight to my nipples, which instantly become hard. I play with the nipples for a while and notice how the pinching makes my pussy wet. Immediately my hands slide further down and I start to give it to myself with my fingers. Just the thing on such a hot day :)
