Nick closed the screen door behind him as he exited the house and walked over to the pool. Anna lay there tanning, her golden skin shining over her soft curves. Nick thought again of Irene and Anna's differences, both where incredibly attractive, Irene in an athlete's way and Anna in an Instagram Model way. Where Irene's muscles made her legs thick and pliable in a dangerously sexy way, Anna's lithe young body held curves that only genetics could give. Nick said hi as he took a seat in the lounge chair next to her as she smiled and took her headphones off.
"Sorry about the commotion, I haven't seen your sister for a bit." He said with a smile.
"Oh no I'm sorry!" She replied with a mischievous smile, "It's not like this is my house or anything, no reason why you can't just fuck whoever you want wherever you want."
Nick took a second to process what she could have meant by that and stole another furtive glance at her perfect body. Her young full tits filling out a bikini top that was clearly too small for the gravity-defying orbs they held. Then he snapped out of it. "Yes! I get your sarcasm," he forced a laugh, "I'll be more careful about where I'm enjoying myself."
"Oh no! That's not what I meant at all!" Anna smiled big and sat up moving much closer to Nick. "In fact I think I'd prefer to see you enjoy yourself more often." she moved in almost a liquid like fashion as she fell off of her lawn chair and onto her knees in front of Nick.
Nick did his best to ignore the slow, sex-filled movements but his cock definitely didn't as it was already fully hard again and the impression it left on the front of Nick's pants was clear. Anna was rapt with attention and had sat up to take a better and closer look at it. Her hands drifted to Nick's thighs as she gradually moved her whole body in a damning position, practically drooling at this point.
"You know, you aren't the only one who hasn't had any in a while" her hand slowly moving up his thighs, getting to the bottom of his shorts.
Nick could not believe what was going on five minutes ago he was balls deep in this girl's older sister, his girlfriend, and now he had her younger sister in front of him, on her knees, in her bathing suit, practically begging him to show her what he can do.
