Jimmy couldn't believe what he was doing. With his beautiful teenage sister splayed out and naked but for a tiny thong beneath him, he was straddling her amazing body and groping her tits for all he was worth. As she laid back with her eyes closed and a dreamy smile on her lips one could guess that she was sleeping and barely aware of his sinful doings, but he knew well that she was fully awake and, judging from the soft grunts and moans escaping her lips every now and then, seemingly enjoying his kneading almost as much as he did.
He didn't know for sure how long he just kept savouring the feeling of her wonderful tits being squeezed and rolled under his palms, but at some point when he had more or less lost himself staring down her cleavage he realized she had opened her eyes again and was watching him with an attentive smile. As she met his glance she slowly pulled her left arm from beneath her head and reached out for the sun oil still sitting at the ground beside them.
"I think we need a little more..." She grinned as she opened the bottle and started slowly pouring a good amount of the oil onto her chest, letting it flow in a steady trickle from side to side of her cleavage. As she finished she put the bottle away again and then surprised him a bit by reaching out and touching him, placing her hands on his muscular thighs and gently caressing her way up to his hips.
"Sis...?" He started, stopping all movements and just nervously staring down into her still smiling face as her petite hands gently tugged at the waistband of his trunks. "Hey, stop that...!"
"Why?" She chuckled, flashing him another mischievous grin while slowly working his pants downwards over his hips. "You got your hands on my boobs, and you think it's not fair for me to check your willy?"
"But..." Jimmy tried to protest, but was too paralyzed in shock to push her hands away or come up with some argument against her reasoning. Instead he just swallowed his objections and looked away in embarressment into the cloudless sky as he felt his hardon spring free of his trunks and also lift it's head up toward the heavens.
"Ohmygod...?!" He heard his little sister gasp beneath him and couldn't keep himself from looking down at her surprised face while she just lay there staring at his manhood. It wasn't really an unusual reaction he had to admit, and he had been with several more experienced women in his life than Jenny. "Are they... supposed to be that big...?!"
"It may be the genes..." Jimmy mumbled while giving her tits another little squeeze, somehow managing to come up with some kind of joke even in his state of shock. Some sort of basic survival instincts, he'd guess. "You're quite well endowed yourself..."
"Thanks!" She giggled, seemingly getting over her own surprise in a matter of seconds as she laughed at his silly comment. "I'll take that as a compliment!"
"Sure..." He quietly replied, daring a quick look down at her as he felt her hands leave his hips. For a second he almost thought she'd want to touch his exposed dick, and felt a slight sting of disappointment as she didn't. Instead she placed her hands on his own much bigger ones that were still clinging to her breasts.
"Come..." She whispered, gently helping him to press her breasts together while giving him a soft and inviting smile. "Give them a try... Just like you did to my butt."
Questions like "You were awake?!" started to form on Jimmy's lips as he stared down at his sister's beautiful face, but all he managed was a slight nod of his head. The valley between her tits sure did look good enough for a dead man to get a serious woody. His own cock throbbed in anticipation at the very thought of what she was suggesting, and before he knew it he found himself leaning forward over her and getting the upturned shaft into a more horizontal position.
"Mhmm..." Jenny let out a little grunt, staring fascinatedly down at her breasts as her brother's fat cockhead pushed up through her cleavage. "Ohmy..."
Lifting his head to the sky again and trying to focus on something completely different than what he was actually doing, Jimmy hesitantly started moving his hips, feeling his sack brush his sister's belly while his massive hardon slid through her well-oiled cleavage. Not his sister, he tried to tell himself while starting to squeeze her breasts again. Not sweet little Jenny... Not his innocent little sister... |
