I 19F was am visiting some childhood friends "Kyle" 20M and "Kristina" 19F in another city. This all happened about 3 hours ago and we weren't the only ones doing this. While I am here they took me to a place where they explained to me that the park which commonly known as couple park, where you commonly found couples in sexual act like kissing BJs, and rarely intercourse behind the trees. After getting settled down on a picnic table near an area dense with trees they both start kissing and sucking me. slowly unbuttoning my shirt to expose my breast publicly which clearly visible to every one present there, but they don't care who see me they just both keep sucking on both my tits. They pulled me up and ripped off my leggings. Now I'm completely naked and Kyle laid me on my back on the table and spread my legs. At this point he wasn't fucking me yet. He was just rubbing his tip on my pussy like he was teasing me. Kristina on the other hand was siting on my face telling me to eat her out and from what I could see she was also playing with her tits. While I was focused on Kristina I forgot about Kyle and he surprised me by suddenly shoving it in my ass instead. I'm not complaining, it did feel good but he was teasing my pussy for so long just to put it in my ass. After I made Kristina cum Kyle also started to shoot his load inside me about a minute later. I'm not sure but I think it's due to Kristina sucking on this sack. After finishing his load inside me Kristina pulled her plug out of her and plugged me up. it was getting around lunch time and we decided to finish things up. Kristina and I took turns giving Kyle a "clean up blowjob".
