Shinka wanted to go to the picnic grounds for a cookout for his birthday and we were going swimming before and after. Our parents wanted us all to dre...s before we went, since the bathrooms at the park were horrible.I had a pair of light blue swim trunks that went all the way to the middle of my knees. They were brand new; I hadn't even put them on yet. Kizuna also had a new swimsuit. It came as no surprise to anyone when she picked out a one-piece light blue one.We both stripped, talking while. His kisses were electrifying, and the noises the other couple were making were turning me on even more.As we kissed, his hands slid down my back and cupped my ass. A jolt of electricity ran straight through to my pussy. I gasped into his mouth and grabbed his ass in turn, things were getting seriously hot. I thought I heard the sounds of a zip from the other couple and knew things there were getting even hotter. She groaned and the noise sounded familiar. Then I got distracted, his hands were. She resisted, more than I had expected.“What’s wrong? That was very nice, Big Brother. Did you feel that? That ... electricity that just happened between us? Could I have another one of those, please?” She smiled so demurely.“Carol – I’m sorry, that was so inappropriate. I tell you ... I-I feel weak in the knees when I’m around you. I just ... lose control of my emotions and you are so gorgeous and your ... your eyes just, just...”“Just what, Rann?”“Ever since you became a teenager, your eyes. My uncle is signalled to lick my mum's asshole. He moves quickly. My dad has a beer bottle in his hand, he drinks the last mouthful and when my uncle is on his knees bent over licking my mother, dad shoves the bottom of the bottle roughly in his asshole. Fucking my uncle with the bottle.My dad leaves the bottle in my faggot uncles ass , moving to my aunt who now is on her knees moaning from my mothers talented tongue, he grabs a handful of mums jet black hair pulling her head toward his.
