"Don’t mind me, Katrina," Brielle said, tucking her thumbs inside her jeans and leaning back on the door. "You can suck your brother's cock all you want as far as I care. I just thought I'd watch, if you don't mind?"
Gerald immediately slammed across the thought that of course she wouldn't mind, in fact, the idea of her stepmother watching would make Katrina even more turned on. Then, as he decided whether or not he should make his step-mom get involved or just let her watch for the time being (it was, after all, her idea and not his, and perhaps he should make the most of that?) when he felt the tip of his sister's tongue on the head of his dick. Instantly any sagging-ness that had occurred due to his embarrassment at being caught was replaced by a rush of blood that had him harder than he'd ever been before.
He turned his attention back to Katrina, whose tongue was exploring the crown of his penis, relishing the new sensations of how it felt and what his pre-cum tasted like. Then her tongue moved down his member until the head was inside her open mouth. She let out a little pant then, and the warm air sent a ripple of pleasure straight to Gerald's brain, causing him to groan in return.
His little sister couldn't believe her luck. She'd been caught in the act of fulfilling one of her deepest fantasies, but her stepmom actually wanted to watch her doing it – like it was a normal thing! This was another fantasy of hers – being watched while getting sexual with someone else. Admittedly, she'd always imagined it would be another guy doing the watching, but her step-mom was pretty hot, for a woman, and the thought of her enjoying the show made Katrina feel even more horny.
All those hours of practising with the little dildo she'd bought on her last vacation were about to pay off, and she couldn't wait to find out what it felt like. She closed her mouth over the end of her brother's cock and started to suck. She looked upwards at her brother’s face and saw him smiling down at her. She tried to smile too, but her mouth was busy sucking.
Instead, she took a little bit more in, and then a little bit more, until she could feel the tip of his dick against the back of her mouth. Then she drew it out and sucked it back in. She wasn't getting as far down his length as she'd thought she would, but then Gerald's cock was bigger than she’d imagined it to be. Her motions set into a rhythm of in and out, in and out, pause to lick the head, then repeat. Every once in a while she'd look up at her brother, or across at her step-mother, who had raised on hand up to softly caress her left nipple through the fabric of blouse and bra.
Gerald had noticed this too, but was concentrating on the incredible blowjob his little sister was giving him. He wished she'd talk dirty to him, like porn stars did on the videos he sometimes watched. No sooner had the thought left his mind than his sister popped his cock out of her mouth and whispered, "Mmm, baby... I wanna make you cum. You big stud, I want to taste your cum," and then proceeded to attack his pole with even more fervour than before. She took his balls with the had that wasn't holding his dick and started to rub them together.
It was enough to send Gerald's hormones to the next level. The sensations and sight of his sister's head bobbing up and down on his cock, with the moaning and slurping noises she was making caused the familiar throbbing that preceded ejaculation, only three times stronger than ever before.
He looked down at his hot little minx of a sister once more and realised he now had no choice but to give her what she'd asked for. The question was, where would he aim for? |
