I missed this part :)
They wore just the party clothes for the short drive to the party. Other guests were already there and the parking places right outside the house were taken. Steve parked a short distance from the house and Emma and Christine wearing just their basques and Mike and Steve wearing just their shorts walked back along the road to the house.
Bill opened the front door to let them in. Behind him stood Linda, naked from the waist up.
"I was going to offer to take your coats but as you're not wearing any I can't. Where are you parked?" Bill said.
"Down the road."
"You're brave walking along the road like that. Were you seen?" Linda asked.
"A police car slowed down. I think they were going to stop and question us but suddenly the lights on their car went on and they sped away." Christine said.
Steve introduced Christine and Mike to Linda and Bill.
Linda held Emma's arm stopping her from walking away and when she was sure no-one else could hear she asked. "Are you sure they're OK with us being family?"
"Yes certain. Don't worry. They're brother and sister. Who's here?"
Emma and Linda caught up with the others who had stopped to watch a couple in a dark room fuck. "Who's that?" Emma asked.
"It's your dad and your nan." Bill replied.
"Fuck me!" Emma exclaimed.
"Thank you. I will." Bill took her hand and Emma looked around the room. "Is that your son sucking your father-in-laws penis?" Emma asked.
"It sure is. Let's join them." Bill said.
Linda led Steve into another room. Christine and Mike followed them.
On the floor in the centre of the room was Linda's daughter Amy. Steve's naked cousin lay on her back, legs apart with his mother licking her pubic mound while Amy's husband fucked Maureen from behind.
Linda pressed her bare breasts against Steve's chest, placed one arm around his waist and placed her other arm around Mike and Christine pulling them close. Linda kissed Christine on the lips and Christine returned the kiss before breaking off and kissing her brother.
Looking up Amy saw her mother and Steve kissing. She watched as her mother pulled down Steve's shorts and Amy studied his penis as her mother sucked and licked it. Her mother guided Steve's stiff penis into her wet inviting pussy and Amy watched her cousin's backside move back and forward as he fucked her mother.
Christine and Mike stood by the door kissing. "Can you believe what we're seeing?" Christine said to her brother.
"This is incredible! Do you want to fuck your brother?"
"I'm a virgin."
"You're a what!"
"I'm a virgin. Be gentle I've been waiting for the right person."
Mike looked around the room but could not see a suitable place for them. In the other room Mike and Christine saw Emma being fucked by her cousin Kevin while her father sucked on her nipples and she sucked her grandfather's penis. Emma's grandmother was sucking Bill's penis.
"We can use those cushions next to them in the centre of the room." Christine said.
Mike was gentle, kissing Christine all over, making sure that she was moist and ready before he pushed his penis inside her virgin hole. He moved slowly and gently before filling her with his cum.
Kevin stared at Mike's backside as it moved up and down. Leaning over he touched it and gave Mike time to object before he pressed his fingers between Mike's crack. Mike enjoyed the feel of Kevin's fingers exploring his anus and did not object when his finger explored inside.
"May I?" Kevin asked.
"Yes." Mike replied and then said to his sister. "I'm about to lose my virginity as well."
Kevin moved behind Mike and pulling his finger out replaced it with his penis.
In the other room Amy leant across to her cousin Steve and cupped his balls as he fucked her mother. "I've wanted to fuck you for years. Now I have to watch you fuck my mother and I hear you've been fucking your sister and mother as well."
"All you had to do was ask."
"Bastard." Amy gave his balls a playful squeeze.
"Do you want to fuck my daughter?" Linda asked.
"Do I have your permission?" Steve joked.
"Yes, but be careful. Her husband's behind you and might hear you." Linda joked.
"Are we changing partners?" Asked Amy's husband.
"You and mum can fuck while Steve and I fuck." Amy said.
"We can't leave Maureen out of it!" Linda said.
"It's all right. My legs have gone to sleep. I'll stretch them and see what they're doing in the other room."
Amy looked at Steve's stiff penis that glistened with her mother's juices as she slid it into herself. Her husband moved between her mother's spread wide legs and she watched him push his penis into her.
At the door to the other room Maureen watched her nephew bugger Mike while Mike fucked his sister Christine. Next to them her husband was fucking his mother and her daughter was sucking her grandfather's penis. Maureen sat next to Bill her brother-in-law allowing him to stroke her pussy while they watched the scene in front of them.
At midnight they all lay in a circle and to the muffled tones of 'auld lang syne' they sucked penis and licked pussy.
"This is the best New Year's party ever." Christine said and Emma agreed. They sat quietly together watching everyone else have sex. Steve was fucking his grandmother.
"Your brother must have fucked everyone except me." Christine said.
"I'm sure he'll fuck you if you ask him."
"You won't mind?"
"Why should I mind?"
"I saw the way you look at each other."
"When you fuck my brother I'll fuck your brother. That is if Mike ever stops buggering my father." Emma said to divert attention away from Steve and herself.
When the others had gone to bed to sleep Emma, Christine, Steve and Mike looked outside towards the car. It was quiet, no-one else was around.
"Let's all walk naked to the car." Emma suggested.
"What!" Exclaimed Christine.
"No-one's around to see us. It'll be fun."
Emma was first holding her basque in her hand. Steve followed and looking back said. "Are you two coming or are we going home alone?"
"Come on it's not far." Mike suggested to his sister as he stepped out of the house holding his shorts in his hand. With new found courage Christine stepped out behind her brother and not to be outdone threw her basque into the car and refused to get into the car after it.
"I'll walk. It's not far. Any one care to join me." Christine said.
All of them remained naked. Emma, Christine and Mike walked with Steve driving slowly behind just in case they needed to jump into the car quickly.
"Come in for a coffee? You're welcome to stay the night." Christine suggested as they arrived at their house.
At the back of the house was a swimming pool where Mike and Steve swam. Christine showed Emma the bedroom where she and Steve would sleep.
"You never did get to fuck my brother."
"And you didn't get to fuck mine."
"We'll fuck our own brothers before we go to sleep, and tomorrow we'll try each other's."
