Malcolm walked quietly to the guest bedroom, and watched his mother-in-law pack her overnight bag.
In his hands were his clothes for the two nights they would be away together. "Shall we share an overnight bag?" He asked.
She jumped when she heard his voice. Her heart raced and, she spat out the words. "Don't creep up on me like that."
"Sorry! I thought you knew I was here."
"No, I didn't!" She held her arms across her chest, leaned against him, and took a deep breath. He smelt good. "You bastard! You almost gave me a heart attack."
He held her in his arms, like an adult comforting a child, her hair touching his face. She smelt of apple shampoo. "I'm sorry. Are we still friends?"
"We will be as long as you don't creep up on me like that and frighten me to death."
"I won't do it again." He hugged her, and with his hand moving across her back discovered she was not wearing a bra. He held her tight, her soft breasts pressing against his chest, and her hard nipples digging into him.
"What do you want?" She asked, her heart pounding.
"It's silly for us to take a bag each, so I thought we might share one."
She looked at the clothes in his hands. "Is that all your taking?"
"Yes."
"If you're a good boy and don't frighten me again I might consider sharing." She smiled at him.
"I promise I won't frighten you." He squeezed her tight enjoying her breasts and nipples pressing into him.
"Drop your clothes onto the bed." She smiled.
"How did you sleep last night?" He asked.
"I couldn't sleep with the noise you and Debbie were making. You two are very loud when you have sex." She had hoped to embarrass him, but failed.
"We know. We've been told before. You and Barry made a lot of noise too. It sounded as though you were enjoying yourselves last night."
"Hearing you fuck turned us on." Sandra felt her face go red at saying the F word, and she pushed Malcolm playfully to cover her embarrassment.
It was only a gentle push but Malcolm fell onto the bed a lot easier than she had expected. He held her tight taking her down too. Landing on him she made a half hearted attempt to escape his grasp.
"Let go of me, Debbie or Barry might see us." Sandra squirmed.
"Debbie won't mind."
"Are you sure?"
"Positive. Will it bother Barry?"
Sandra shrugged, hoping that her husband would not mind what she was doing with their son in law.
She squirmed some more in a half hearted attempt to escape his grasp, only stopping when she felt his hard penis pressing through her clothes. Sliding her hand inside his shirt she rubbed her fingers over his chest. "I'm looking forward to our trip to the Bio Dome."
"So am I." Malcolm was not thinking about the Bio Dome as he ran his fingers through her hair. He was thinking about what might happen between them in the bedroom they would share that night.

Later that morning, standing by the front door Malcolm hugged and kissed his wife goodbye. A few steps away Debbie's parents were doing the same thing. Holding Malcolm's hand Debbie guided him over to her parents.
"Let's have a family hug." Debbie placed her hand on her father's arm, and her parents moved apart giving them the room to join in. Debbie linked arms with her husband and father and, leaning forward kissed her mother. Both Debbie and her mother felt Barry's penis stiffen against their thighs.
"I feel overdressed standing here with you two." Sandra said to her husband and daughter.
"We'd better go. We've got a long drive ahead of us." Sandra said to Malcolm.
Although Debbie was naked she stood outside and waved to her mother and husband as they drove away. Her father stood back in the hall so the neighbours would not see that he was naked.
"You enjoyed standing outside naked didn't you?" Barry said to Debbie as she stepped back inside and closed the door.
"Yes, I get a thrill out of doing it."
"Aren't your afraid your neighbours will see you and complain?"
"They've seen it all before and never complained. I think some of them get off on it."
"You're lucky to have neighbours like that."
"You've got neighbours like that too. I can't imagine Catherine or Ian objecting to you or mum being naked."
"They wouldn't mind. But your mum would tell me off."
"No she wouldn't. She's been okay with us all being naked for the past few days."
"We might have a problem with mum. Last night she heard you and Malcolm talking, and whatever she heard made her get out of bed and stand by your bedroom door. From what I heard it sounded as though you were have sex."
"She's a voyeur."
"Don't joke about it. This could be serious. What were you talking about?"
"I can't remember."
"She quizzed me on what you and I did while she was out shopping yesterday."
"How long did she watch us?"
"Long enough to get turned on. We had a wonderful fuck when she came back to bed."
"We heard you. It turned us on." Debbie sounded aroused.
Bringing his hand up to his daughter's face Barry gently touched her cheek with his fingers. "Your mother's the love of my life and, I know it's wrong, but all the time I was fucking her last night I was thinking of you."
Debbie was excited and, she kissed his fingers. "Let's fuck now." She walked towards her bedroom, then realising that he had not moved turned towards him. "Come on. I want to have sex with you now."
She was planning to fuck him cowgirl style. But when they got into the bedroom he took charge. Laying her on the bed he put his hands on her knees and moved them apart. He inspected her beautiful labia and, kneeling between her splayed legs put his tongue between her puffy lips and, licked along her moist slit. She tasted good. Easing the tip of his tongue into her he moved it in then out of her.
She lay still, and felt her father's hot breath bathe her pussy, and with every lick of that sensitive area the intensity of her orgasm built up inside her until she was screaming. Neither of them cared that the windows were open allowing the sound to broadcast what they were doing to the neighbours. The old man from a house opposite heard them as he walked to the local shops. He knew what was happening, he had seen her naked and heard Debbie's screams before.
