After a little deliberation, and a lot of confessions about where in the house exactly they had had wild young sex (including Alex telling how -- on her eighteenth birthday -- Daniel's best friend Liam had banged her on Daniel's bed as he shagged Alex's friend Tina on hers), they knew of only one place neither had had sex of any kind.
Alex sat naked on the kitchen worksurface; hot legs akimbo so Daniel could fuck her tits off with his huge knob banging through her pussy. His hands groped her tits as they came to a few quick orgasms, and they finally, snogging their brains out, stopped with a hug.
"Correct me if I'm wrong," Alex grinned, wiping sweat from her brow, "but I don't think we should have done that."
"You're wrong, so I'll correct you," Daniel grinned back, running his hands down Alex's moist titties before pecking her lips. "What took us so long?"
"I dunno, it's been ages since we turned eighteen... well, three months anyway. We've had so much sex since then."
"Tell me about it," Daniel whistled. "Should we tell anyone?"
"Erm... might be difficult not to. How will everyone react?"
"I don't know." He pulled out, his still hard knob dropping between his legs. Alex knew her parents would be back tomorrow, perhaps in the afternoon, and didn't want this to end now. "I'm more worried about what mum and dad will think."
"Oh, we're definitely not telling them," Alex protested. With the help of her twin, she jumped down from the worksurface; the jolt of landing displacing a little cum from her pussy that ran down her leg.
"Ally," Daniel replied, using her usual name for her, "they're gonna notice something's amiss when I smell of your perfume... or dad catches you leaving my room at three in the morning."
"So, we're carrying on?" Alex asked on a tangent. It was such a hopeful question that Daniel smiled and almost laughed. He moved against his twin; their naked bodies pressed together, and he kissed her again.
"We've got the place alone tonight. Let's enjoy it."
"Where and how?" she asked in her sexiest voice. That strong Irish accent Daniel was so used to tore through him, so filling him with desire he just wanted to keep filling her cunt.
"Your room and anal."
Meanwhile, in the Belfast hotel, Murphy and Catherine were enjoying not having to keep the noise down. Although they were sure their two beautiful children were having lots of sex themselves with their peers, they knew kids didn't like the idea of their parents having sex. And it wasn't like these two people only did it once a week.
Whenever a night came around when the kids were out, they'd just get down to it instead of watching TV; almost resulting in them getting caught once in the living room semi-naked pre-penetration. Luckily, neither looked their way for long enough for them to get dressed and act like Murphy didn't have a massive boner, and Catherine's panties weren't soaked through.
The two guys had since left, and after Catherine had begged a suitable amount of times, Murphy realised she was serious about having women in the bedroom with them.
"I never knew baby," he panted, lying naked on the bed as Catherine, naked also, wrapped her hot lips around his stunning, fat knob.
