We splashed and played in the refreshing water, throwing the ball for Screwball, laughing and bantering, just having a fun sibling episode. Neither of us was self-conscience about frolicking in our underwear, it became a non-issue as soon as we were in the water. After a half hour or so Helen got out of the river then went into our tent, moments later she stepped out to hang her delicate wear on a tree branch. She was nude. I stopped moving and stared at my sister, she turned and saw me looking at her, flushed pink in the cheeks then scuttled quickly back into the tent. My cock flared with carnal interest. The dog leaped at the ball, reminding me he was still there. That was the last full day at the Groupsex camp, we would be leaving in the morning. After dinner mom and dad shared the last of the beer with us while they showed us dozens of pictures taken on the hikes. A little before ten that evening, they bid us good night and went to rest. Helen and I were left to stare at the stars. We ignored each other while we tried to get signals on our smartphones but it was a wasted effort. In three days, we hadn’t been able to connect with friends or Facebook. My sister gave up and said good night then retreated from the moonlight to the tent. Me and Screw stayed outside, giving her time to get settled in bed. It was well into the late hours when I finally went to join Helen. Screw took up his position in the middle of his sleeping bag and challenged me with his eyes to push him away. I didn’t even try. I changed to my sleep wear then went to bed with my sister. I turned off the battery lamp before I crawled into the bag next to her so I didn’t see Helen as I lay behind her. When pussyfucking I was on my back in the bag she shifted slightly, bent her leg at the knee Hardcore which put her foot on my lower leg. Her toes twitched against my ankle which caused a thrill to shiver up my leg. blowjob Helen turned over to face me, looped an arm over my chest and snuggled to my side. Her breasts were pressed on my shoulder, her legs rubbing mine. My cock exploded in length and girth, I started to panic because if she didn’t move, I would start something she might not like again. I reached across my body to push her away and when my hand touched her, it was bare skin I felt. My head jerked back, I squinted in the dark at her then moved my hand from her shoulder down her side. She wasn’t wearing anything. Helen was naked under the blanket. My heart started tripping, my face flushed hot, my cock bobbed with each quickened heartbeat. Moments later they all started to cum inside me and Mr. Johnson fed me his cum. I wanted her, and I wanted her BAD! I groaned, my body swaying Groupsex two and fro. “Who cares, let’s just use unisex one,” Anna says as she gets up and pulls pussyfucking Nicole behind her. "Well, what with sexual equality and all that..." then she revealed what she was hiding behind her back. She nodded. Well dad anyway as mum wasn’t going to be back for two weeks. comprehensible words coming out. She heard the shower going, so she sat in the chair that Ethan blowjob had used the night before. “It sure feels like it,” Jess says as she gets up from the table and rushes out the backdoor. I was thinking kind of like a Hardcore black jacket with a hood.
