Secretly fucked in the garden

At the family party, I noticed that my sister's boyfriend really wanted to undress me with his looks. I had the feeling that he was imagining what I looked like under my clothes. Luckily, no one else noticed how much he was staring at me. When he came round again, he went out into the garden and I followed him. I wanted to confront him but before I knew it he was whispering in my ear that he had just imagined me nude and he was so sorry. I just thought, hmmm.....should I take advantage of the situation or not? Oh fuck it...and I already had his cock in my mouth. Mmmhhh...he was so delicious, I couldn't stop blowing but I wanted to take full advantage of the situation so I took off my trousers and got on his hot cock. Fuck me deep in my pussy and fuck if the neighbours could catch us. I really enjoyed being fucked by a guy who didn't give a shit about anything else at that moment. But I still hope that nobody really caught us, because I'm not such a bad sister.
