Five Years Later
Twenty year old Olvido Santos climbed the stairs of her home and walked into the bathroom. Entering she left the door wide open, stripping off she sat on the toilet, legs wide apart, waiting. Antonio her brother crept up the stairs until the turn gave him a perfect view of his sister. Sensing her brothers presence she raised her bottom slightly and pushed; a thick stream of golden piss jetted out of her pussy, it shot into the toilet bowl and bubbled and boiled in the water. Standing, she wiggled to lose the last drips and walked out without flushing. She walked to her bedroom and striding in, managed to not close the door. She waited a few moments, hearing the feint creak of the flooring outside her room,
"For God's sake Antonio, get in here, I have something for you."
Olvido lay back on her bed, her fingers massaging her clit. Outside the door her younger brother Antonio, peeking through the gap in the door was surprised that his sister knew he was there. He had been spying on her and gently wanking his cock as he watched her lay back on the bed. They had seen each other nude since childhood, spending hours on the local nudist beach, but this was so much more arousing.
Every since he could remember Antonio had been sporting healthy erections around Olvido. He was besotted with his sister and followed her around everywhere much to her consternation. As she developed into a women, Antonio seemed to have a continuous erection. On reaching adulthood, his lean body had muscled up and his body hair had grown thick and fast, which proved very attractive to his sister. He loved his sister helplessly and still trailed hopelessly around after her.
"How did you know I was there?" he grumbled as he walked into the room, his cock pointing up to his muscled belly.
"Because your name's Antonio and since you were four years old you've been trailing round after me." she offered, turning on her side and looking at his cock.
"Okay, but how did you know I'd follow you in here and peek at you?"
"Because I said "It's too hot and I'm going to strip off and lie on my bed" I think," she smiled.
"Am I that predictable?" he asked.
"Yes and I know that as soon as you see me naked your cock's going to stand up like a soldier on parade," she laughed.
"Gulp, sorry, can't help it if you turn me on, you're gorgeous Olly, and you know it." he smiled.
"Maybe, I don't think so, but as long as you think so I'm happy; now you're here, let me explain what's going to happen. You're going to get onto this bed and stick that lovely looking cock in me and fuck my brains out, that is if you can last longer than fifteen seconds." she looked at him and raised her left eyebrow suggestively.
"What, I'm really going to get to fuck you? really? why? why after all these years of complaining and cursing me, why now?"
"Because it's your eighteenth birthday and I can't think of a better present for my lovely little brother than me, what do you think, am I generous or what?" She held out her arms towards him.
"Whoa, wait a minute, you're a virgin aren't you, I can't do that Olly, no way you must to save that up for someone you really love."
"Dear sweet brother, that's exactly what I'm doing. Antonio, you lovely dunce, you are the love of my life, compared to the other boys in my year and most of the older one's, you're damn near perfect, so come on lover get here quick, my engines cooling and I want to enjoy you hot."
Antonio moved to the bed and sat beside Olvido, gently he brushed a few hairs from her face then leaned in and kissed her, on the mouth , feeling her lips parting. They moved together and he felt the sweet soft skin of his older sister. He stroked her side and back, feeling the soft supple skin under his hand curving and rising under him. She broke the kiss,
"God, you're a better kisser than I ever imagined. You're hot little brother, kiss me more." She pulled him back to her and they met again, this time the kissing went undisturbed by conversation.
After a while she move slightly so that his erection was between them, she pushed against it and rubbed it against her skin.
"Move around little brother, let me get on top of you."
Antonio rolled onto his back, as Olvido moved above him, he marveled at her curvy body and bare mound. Slowly she lowered herself down to his cock, reaching down to grasp it. She pointed his long thin prick towards her, rubbing it carefully along her wet slit, before pressing his cockhead against the opening. Shifting slightly she lowered herself onto him, feeling his thin prick ease into her slippery channel. She felt him filling her up, the cockhead now free of the foreskin pushing against the sides of her vagina.
She breathed out and relaxed as she felt him slipping deep into her core. Antonio gasped as his cock went into his sister and a velvet glove lovingly grasped it, pulling him deep inside her and only stopping as her labia met his groin and her bottom touched down on his legs. Olvido grinned and ran her hands across his chest and began to play with his nipples feeling her clitoris mashing against his pubic hair and the base of his prick
