Fingered on his terrace on the first date

He wanted to cook for me, so he invited me to his house. It was so warm outside that I sat on the sofa while he was cooking inside. Since I didn’t have time to finger myself at home before the date, I thought I’d do it on his terrace. He couldn’t see me that well anyway, because he was standing with his back to me and there was a thin curtain between them. So I took off my panties and did it right on his sofa. OMG, that was so damn risky but also so hot! Every now and then he came out to ask me something and then I acted like nothing was wrong. Haha, I’m a slut, aren’t I?
