This is the third chapter of an ongoing three-way romance between a brother and sister, and the brother's bisexual girlfriend. To recap: Valerie, a cute and kinky twentysomething blonde, falls in love with her boyfriend's lovely younger sister, Anya. After a drunken night out, Valerie seduces Anya and has passionate sex with her. Anya admits that she is secretly in love with her brother Cal, and also reveals that she was badly abused by her past boyfriends. Valerie decides to get Cal and Anya to have sex, in the hope that she can have a relationship with both of them.
As before, be aware: this is an incest story which also has strong elements of bisexual/lesbian romance and some pissing (though not as much as earlier chapters). It also has a backstory involving abusive relationships, but the main story itself does not involve any kind of abuse. Comments are welcome.

Valerie lay naked in the darkened guest bedroom and waited for her boyfriend to return. She knew it was well into the early hours of Sunday now, and she hadn't slept a wink. Usually she would be impatient with arousal, eager for Cal to get back and fuck her raw. He tended to come home horny when he'd been drinking, and she was always happy to oblige. But she'd already had sex tonight, three wonderful, passionate times - and not with Cal.
Anya was sleeping peacefully by her side, her long, graceful legs warmly entwined with Valerie's. Cal's little sister was so beautiful, even with only the faint outlines of her angelic face visible in the darkness. Her naked body was only half-covered by the disordered sheets, and Valerie couldn't help but gently trace her fingers over her full, firm breasts as they lay together. It took all her self-control not to do more to the sleeping girl - to kiss her, fondle her, lap at her gorgeous tight pussy. She very much wanted to wake Anya up and make love to her again, but she knew how exhausted the younger girl was; she had a lot of wine to sleep off. And Valerie couldn't let Cal catch them together, at least not yet.
It was past four in the morning when Cal finally came home. He'd been out with his friends for hours, and Valerie knew how much he liked his beer. She listened to him walk heavily through the dimly lit living room. She worried momentarily that he would notice her and Anya's discarded clothes on the living room floor, but it quickly became clear that Cal had only one priority. She heard him stumble into the bathroom further down the corridor and click on the light. After a long night of drinking, she knew exactly what Cal would need.
"Ohhhh, fuck," Cal sighed loudly, and the sound of his drunken piss filled the silence. Valerie listened, silently aroused despite her nerves. She decided now was as good a time as any. She rose from the bed, kissing Anya's lovely pale face as gently as she could so as not to wake her, and padded naked out of the room.
Valerie saw Cal's tall, muscular silhouette in the doorway of the bathroom. He was dressed in loose grey jeans and a checked shirt, and was barefoot - he must have kicked off his shoes in the living room. His back was to Valerie as he struggled to piss out God knew how many pints of beer. Valerie walked silently up to him, her pussy wet and her nipples standing up hard with arousal once more. She could see Cal's cock dangling down, uncut and enormous, pissing a ceaseless flood into the toilet. Any other day, she wouldn't have hesitated to initiate a sexual encounter with him. But this time, she had Anya to think about. Her only hope of keeping that heavenly girl in her life, without ruining her relationship with Cal, was to get the two siblings to become lovers.
She watched Cal urinate for a very long time, walking closer to him slowly, her bare feet silent in the carpeted corridor. She was almost right behind him before he noticed her. His piss stream gradually dwindling at last, he turned bleary-eyed and smiled a tipsy smile when he saw her nakedness. "Hey, Vali," he said, his voice drowsy. "You look so good, babe."
She stood beside him, standing on her tiptoes to kiss him on the cheek, and softly stroked his broad, muscular back through his shirt. Wordlessly, she reached out her other hand and gripped the enormous shaft of his cock, giving it a gentle squeeze that made him grunt with pleasure.
"I thought you were asleep. I broke the seal," Cal said apologetically as he let her shake away the last drops of his piss. He slid his strong arm comfortably around Valerie's naked waist and leaned his head down to kiss her ash-blonde hair. "Didn't mean to wake you."
"I don't mind. I like watching you," she replied. She felt Cal gradually becoming hard in her grasp, his big cock growing even longer and thicker. His foreskin was pulling back to reveal the swelling red tip of his glans. His balls hung down big and heavy. She gently rubbed his shaft, stroking her fingers playfully along its glorious smooth length. "How much did you drink, honey?"
"Fuck, I don't even know. A lot. It was two-for-one pints all night. The rest of the guys were wrecked to shit by the time I left. I paced myself, though." Cal was slurring his words slightly, but Valerie could see he wasn't very drunk, more just sleepy.
"And how do you feel?" she asked him, kissing his shoulder. She massaged his stiffening cock as gently as she could, hoping that arousal would wake him up a little.
"Kind of drunk. Tired. Happy to see you," he said, eyeing her naked breasts with a lecherous smile. "You look so fucking good. I think I can manage a quickie. Not too drunk for that, at least."
"Mmm, not yet. I like playing with it," she said, and he chuckled and kissed the top of her head. She continued to stroke him gently but teasingly. He was still some way from being fully erect, but he certainly wasn't flaccid any more.
Then came the question she'd been silently dreading. "Did you have fun with Anni?" Cal asked, his arm still loosely round her slender hips.
"Yeah," Valerie said, keeping her face as straight as she could. "Lots of fun."
"How long were you out?"
"A few hours. Anya loves her wine." Valerie kissed Cal's shoulder again, still holding his dripping cock. "She drank so much we had to stop for her to pee on the way home. She pisses like a racehorse, just like you, honey. It was hot to watch."
Cal frowned at her in surprise. "Come on, babe, that's my little sister. Don't get pervy on her."
"I couldn't help it," Valerie said. She realised she was crossing a line from which she could not retreat. She felt fear and shame and delightful wickedness as she went on. "Anya's so beautiful. She pissed a flood," she added, squeezing Cal's cock and making him flinch in surprise. "I watched her, I was touching myself the whole time, baby."
"Vali, what the fuck?" Cal said. There was actual shock on his face. "I mean, why would you tell me that?"
"There's more, Cal. I'm sorry." Valerie locked eyes with Cal, letting go of his dangling penis. She took a deep breath. "Cal, after she was done peeing, I kissed her. I fingered her pussy. And she kissed me back."
