Hottest Encounter

I'm 23 F and I have become obsessed with having sex in public my friend with benefits is equally obsessed. Most weekends we will head to a spot get naked and he'll fuck me like a dirty slut until we can't cum anymore. I've been talking about how It'd be hot to have someone catch us and they'd watch from the darkness masturbating to us and last night it happened. We were driving on our way to this lake park in the car I pulled my top down so my tits were exposed to the cool night air and pulled my skirt up so I could touch myself. My friend R pulled his hard cock out and I stroked him as well I made myself cum but he wasn't ready. When we got to the lake we found a good spot he pulled my tits out sucking my nipples while he rubbed my clit and fingered my pussy. I dropped to my knees and sucked his cock until he came down my throat and then he pulled my dress off leaving me exposed and naked he stripped as well and spread me out on the backless stone bench where he ate me out until I came again and he was hard. He pushed my legs up and out opening me fully and slipped his hard cock in me slowly leaving me panting and begging. He set a hard rhythm that left me weak I was getting close to an O when he told me there was someone just outside the light from the lamp post watching us. When I looked I saw him standing there his hand stroking his cock. R didn't stop in fact he picked up pace and made me cum he spun me around and had me lick him clean while he showed me off to the guy. I climbed on Rs lap and began riding him everytime I looked at the guy he got closer until R called out asking if he wanted to join I was shocked but so turned on I was down so was the guy he walked up and R told me to suck the guy while I ride. I did as I was told R then suggested they switch the guy put on a condom and I got on my hands and knees and the stranger slipped in fucking me hard and R matched his pace fucking my throat. They switched a few more times using my mouth and pussy like toys until they came R filled me while the guy came in my mouth. I found out later he was a friend of Rs and it was all a set up but it was so hot I don't even care.
