I told myself to go, to make my way back through the grass to the beach and run as fast as I could back the house. That’s what I told myself, but when I saw the scene he was actually watching, I stood transfixed, unbelieving, paralyzed.
Brian was spread-eagle on a towel in the sand, Janie straddling him, both of them completely naked. He wasn’t inside her of her-not yet. Her back was mostly to me, but I knew it was her, from the spill of her honey-colored hair over her shoulders to the Celtic tattoo in the small of her back that she’d shown off to Gretchen yesterday in the kitchen during dinner.
Brian’s cock was in her hand and she stroked it between her ass cheeks as she rocked, obviously getting ready to fuck him. Staring, I moved further into the weeds, parting them so I could see better. Now I could see them almost from the side, Janie rubbing Brian’s cock between her legs. He gripped her hips, his fingers digging into her flesh, his eyes half-closed. They were only about ten feet from the cabana where Henry was hiding watching…and about twenty feet, now, from where I was hiding…watching…
“Oh yeah!” I heard Brian’s groan clearly as Janie slid him inside of her. I even heard her soft cry of surprise and pleasure, the sound carrying toward us downwind. Glancing at Henry, I saw his gaze on them, his cock hard in his hand as he watched his sister being fucked.
Had he followed them down here? Just stumbled across them? For a moment, I found myself angry that Brian and Janie were given so much freedom, that they were down here doing whatever they felt like on the beach in the first place-but I had to remind myself that they were grown-ups. Janie was drinking age now, for god’s sake. Henry, too, was an adult. Mr. and Mrs. B. probably wouldn’t care if their daughter had brought her boyfriend down to the beach for a little rendezvous… but what about their son’s activities as he watched his sister getting fucked?
“Ohhhh yes, yes, Brian, harder!” Janie’s voice carried again as she threw her head back, her breasts pointing skyward as she rocked on him. Brian had taken over most of the motion, though, his hips bucking her up and up, again and again. Christ, she was beautiful, her body pure perfection, a long, lean, tawny treasure, not a tan line in sight. I found myself wondering if Janie was shaved, like her mother, and the thought made me flush. I told myself it was from shame, but my pussy throbbed and I cupped my mound through my jeans to quell the ache a little.
I couldn’t decide where to look-knowing I shouldn’t be looking at any of it.
Henry was stroking his cock faster now, biting his lip as he peered around the cabana, watching as his sister rode her boyfriend like he was some bucking bronco, Brian’s hands cupping her breasts, kneading them in his hands. Janie leaned over him and pressed her breasts into Brian’s face, giving both Henry and I a full view of her pussy taking the full length of her boyfriend’s cock.
I suppressed a gasp and found myself wanting to get closer-god help me, I wanted to see. My hand rubbed unthinkingly between my legs, shoving the seam of my jean shorts up between my pussy lips, seeking the hard, aching button of my clit, looking for some sort of relief.
Then Brian was turning her over and Janie complied, getting up on her knees and arching her back, her bottom rising into the air like a cat that wants petting. He positioned himself behind her, his cock nice and slick and hard as he stroked it against her ass. Oh god, that was gorgeous. Simply stunning.
The little squeak that Janie let out when he entered her made my nipples tingle with longing, and I found myself slowly unzipping my shorts and sliding my hand inside for the second time that morning. I couldn’t help it, apparently, any more than Henry could have. That’s what I told myself as my fingers found my clit and began to rub it-that he’d stumbled across them and, like me, had been so surprised at first he couldn’t move… and then… well… nature does take its course, and sometimes urges are so strong…
Henry’s fist encircled his cock, pumping faster as he watched his sister now taking her boyfriend’s cock doggie style, and I wondered how he could stay so quiet. His face clearly showed both his pleasure and his restraint-he didn’t want them to know he was there, but he loved watching, was just as turned on as I was. And oh god, I was.
One hand crept up under my t-shirt, tweaking my nipple as I watched Janie getting fucked, her blonde hair hanging down over her face, her breasts swaying beneath her in the sand. The towel they’d been lying on had been forgotten in the heat of the moment as Brian pounded her hard from behind.
“Oh god, oh Janie, oh god baby I’m gonna-“ Brian’s warning brought an instant reaction from Janie, who shifted her hips quickly forward.
“Not inside!” She gasped, grabbing his cock and turning to start stroking and sucking him.
