"Oh fuck! Oh fuck me you fucking stud! Yes! Yes! Yes!"
Waking up half the street was Alex; her naked body riding on top of her brother's as her pert ass smacked against Daniel's thighs and her heart-stoppingly fantastic huge tits bounded around between gravity and her brother's more-than-keen hands.
It was early, but not too early; they'd slept together and only just woken up. Alex had awoken first, and feeling Daniel's massive hard-on, couldn't resist acting out the wet dream she'd just had by mounting it immediately. Daniel woke up to the irresistible sight of his naked sister fucking him senseless.
With one final deafening scream, Alex came and that tipped Daniel over the edge. He spunked yet more hot, fertile cum into his twin and Alex fell off him to lie by her brother's side.
A shocked face watched from the doorway and quickly left. Completely unawares, the twins stared adoringly at one another and kissed.
"Morning," Alex giggled, stroking Daniel's cheek as he stroked her majestic breasts.
"Morning sexy. Mum and dad are back from Belfast today, have you thought anymore..."
"So, that's what our son and daughter get up to in their private time, is it?" Murphy said, after hearing Catherine describe what she'd seen over the boiling kettle in the kitchen. "Serves us right for being back early."
"Murphy!" Catherine said as quietly as she could muster despite her shock. "Our kids are fucking like rabbits. And not just their friends. Each other, Murphy; they're fucking each other."
"What do you want me to do about it?" he asked. "I'm not going to get mad."
"It's unnatural."
"Some would say that about a happily married couple who fucked around with two guys and three girls after a night out at the theatre. Girls the same age..."
"I know," Catherine exasperated. "What do we do?"
"We talk to them."
"Mum? Dad?" spoke voices from just inside the kitchen. They turned and looked to see Daniel and Alex, fully dressed, looking a little apologetically at their parents. "We have to talk."
"You saw!" Alex screamed as they all sat on the sofa. "Oh my God, I'm so embarrassed," she blushed, turning away and towards Daniel.
"It's okay, Alex," Catherine said. "It's okay."
"You almost sound like you approve," Daniel spoke sceptically.
"I wouldn't go that far, but... you two obviously love each other, and that love has turned into something more passionate and sexual."
Daniel looked to his father; Alex still too mortified at the thought of her parents seeing her moist naked body writhing on top of her brother to look anyone in the eye right now. "Dad?"
"I'm fine, son," he confessed. "Don't worry about me. How long has this been going on?"
"Last night, I seduced her," Daniel admitted.
"And you've just had sex, or..."
"Murphy!" Catherine reprimanded.
"What? I want them to be confident enough to flaunt their relationship about the place. And to do that, I want them to be confident enough to tell us what they get up to."
"You don't tell us," Alex said, looking up for the first time.
"Last night, your mother got fucked by me and two male actors, then we had three girls your age have an orgy with us."
