Murphy and Catherine were very proud parents. Both in their late thirties, they'd got married early and had two children; twins Alex and Daniel. They were both eighteen now, and a month away from leaving home to go to university not far away in Belfast.
Both had realised that their children had been a little too close for some time now, but as Alex had a boyfriend, they trusted any concerns were no longer necessary. Both hadn't been out for a while, so Murphy booked them into a hotel in Belfast so they could go to the theatre and stay away for the night.
"You're not leaving?" Alex said to Daniel. "But Tim is on his way. He'll be here in half an hour."
"And?" Daniel replied, continuing to make his coffee. "I'm not stopping you two from fucking."
"We don't fuck, Daniel, I told you."
He laughed at his twin; a stunning black haired big titted girl he fancied the ass of, despite them being blood relations. "Yeah, right. He's hot, you're fit... what's the problem?"
"If you think he's so fit, you fuck him."
"Maybe I will," he smiled.
Alex smiled too now. "Oh my God, you're fucking gay."
"If I was gay, I wouldn't have had that bath with you."
"Oh, we were pissed."
"And. It was fun. Besides, I'm actually bi. Just like you."
"I'm not bi!" Alex protested.
"Of course. Sure. Absolutely."
"Fuck you!"
"See, you're nasty," Daniel teased in a mock camp voice. "Fucking your own brother."
"We didn't fuck," she pointed out, walking off towards her room.
"True. But I do know what you look like naked. So... I'm off to have a bath."
Daniel was there later, naked in a clear bath of hot water when Alex came into the open doorway. "Tim's not coming," she said.
"Then strip."
"Daniel, this is wrong!"
"So? I wanna see your titties, let me see them."
Alex found Daniel so handsome; lovely short hair, beautiful eyes, and she already knew from the illicit drunken bath they'd had together (in which no contact took place) that he was very well endowed. She'd even listened into a girlfriend's conversation to hear about how he pleased her when they shagged two months ago, and she spoke about how wet he could make her by speaking in his Irish accent.
The accent didn't affect Alex as much as her girlfriend as she was Irish herself, but he was still so lovely, she couldn't resist. And with the absence of their parents who interrupted them last time, there was nothing to lose.'
Alex stripped off her top and skirt, before strutting to the bath. Daniel came to the edge expectantly, and Alex knelt down by the side to move her head to his. Immediately, his head moved forwards and his tongue went down her throat.
Shocked, she couldn't reciprocate for some time, but as Daniel slipped a wet hand inside her huge bra to fondle her fantastic boobs, she decided to do so as she put a hand into the water to feel around for his crotch.
Daniel soon became a little impatient and unclipped Alex's bra, dropping it into the water as he took his tongue from his sister's keen mouth and placed it on her naked FF cup breasts; massive great things he groped and licked. On the umpteenth suckle of a nipple, Alex groaned and stood, before turning around. She felt her brother touch her bum and she bent over before sliding her thong off.
Her ass stuck out, as did her swollen clit as she exposed a cleanly shaven cunt. She was so wet, and only got more so as he pulled her in reverse to the bath, sat her precariously just past the edge, and positioned his head so he could take a long lick of his twin's pussy.
She screamed louder than anything he'd ever heard, and carried on. Reaching around her backwards, he managed to cup her incredibly massive tits and tweak her nipples as Alex squealed her brother's name. He continued mercilessly licking her cunt; sliding two fingers into her eventually, and soon she spurted cum all over his face.
"Ooh, you're a spurter," he smiled as Alex stood up.
