Guys first small paragraph is M-rated not to much detail but you can skip it you want, its not nessercary for the rest of the story.
Sex
Adam pinned Kono against the wall, lifting her shirt over her head to trace patterns all over her body. He flicked the clasp on her bra revealing perfectly round breasts waiting to be touched, her nipples hardening by the second. He took her right nipple in his mouth and he played with the other, alternating between the two. Kono undid the button on his jeans, pulling down the zip and pushing his jeans and boxers to the floor, his hard member brushing against her leg through her jeans. Adam undid her jeans and pushed them down in one swift motion, cupping her through her panties, and then pulling them down also. He captured her lips in a searing kiss that took her breath away, his tongue exploring her mouth. Kono moaned in delight. Adam lifted Kono in his arms, laying her on the bed and hovering above her. Adam lowered towards Kono, covering her body before entering her in a quick thrust, rocking together until they became one….
"Auntie Kono, why were you and Uncle Adam making strange noises last night?" Grace asked as Grace, Adam and the team sat around Adam's patio table having breakfast.
"What!" Kono choked as she almost spat out her orange juice. Her face turning a shade of red that matched Adam's. Danny's face reddens also but Kono guessed that was due to anger.
"Last night I got up to get a glass of water and when I passed your bedroom, I could hear strange noises and you kept screaming Adam's name" Grace stated with all the innocence in the world.
Kono's face became even redder. Grace had stayed the night with her and Adam as Danny and Steve had stayed up on the north shore after a long case.
"Grace sweetie would you go grab me a glass of water?" Danny said simply leaving no room for discussion.
As Grace ran inside Danny turned to Kono and Adam glaring at them.
"What the hell Kono! Could you not keep it in your pants for the one evening I let my daughter stay with you?" Danny exploded
"Don't just shout at me" Kono said in defence "Adam was a willing participant!"
"Oh believe me I'm equally pissed at him!" Danny said, staring at Adam daring him to argue.
"Danny were sorry" Adam started to say
"No were not!" kono cried. "Last night was awesome, I'm not apologising for that, I dint expect Adam back from business until next week, when he surprised me I couldn't resist, besides Grace was in bed" Kono said trying to argue her point of view.
"Well clearly she woke up and heard the two of you! She's twelve Kono!" Danny yelled, anger boiling.
"Exactly Danny, she's twelve not four, she probably already knows stuff about sex" Kono said
"Well she will now, she will be asking me about it now and I'll have to be the one to try and have a sex talk with my daughter! And if I don't speak to her about it, she will tell Rachel who will then ban me from seeing my daughter because I let her stay with the resident porn stars." Danny ranted as his hands flew around all over the place.
Before Danny killed someone-Kono, Chin piped up.
"Well why don't you punish Kono my making her have the sex talk with Grace" Chin said, pleased with himself that he found a solution.
"Cuz!" Kono yelled, not ready to be telling her niece about the birds and the bees.
"I totally agree with Chin" Steve piped up.
"I suppose that could work." Danny agreed.
At that moment Grace returned.
"Hey monkey, Kono needs to talk to you, she will drop you home later, and we have some stuff to do"
And with that Danny,Chin and Steve left.
"I have work to do also" Adam rushed out before running to his office.
"Hey!" Kono cried
An hour later.
Kono had put of talking to Grace for the past hour they now sat together on the coach.
"Hey Grace so I need to talk to you about something" Kono said
"What's up?" Grace asked
Kono fiddled with her hands trying to find the right words. "Grace do you know what sex is?"
Grace rolled her eyes "When a boy and a girl really like together, the erm twiglet goes into the hola hoop" Grace said shyly
Kono giggle at the analogy Grace gave.
"Yeah but you know the twiglet isn't actually a twiglet?" Kono said
"I know…!" Grace drawled out.
"Look last night when you heard me and Adam making strange noises, we were ermm well having sex" Kono said embarrassment spreading across her body.
"I know" Grace said with a smirk.
"What! What do you mean you know!?" Kono exclaimed
Grace started to giggle hysterically. "You promised me we would have a girl's night together, but when we got home and Adam was here, you forgot about me and you were all over Adam and smooching and gross" Grace said making a face at her Auntie. "So I rung Auntie Catherine and told her you were being boring and asked if she could come over and have girls night with me, then maybe you would join in, but she was busy, so I explained what happened and she said I should get you back, so I decided to pretend I heard you and Adam, yah nooo." Grace said giggle still
"Wait you never actually heard us?" Kono asked, realisation hitting her.
"Nope, not a thing!" Grace said
"Oh my god I'm so embarrassed, I acutely admitted to your father that I had sex with my boyfriend with you in the house all because you said you heard us and It wasn't even true!" Kono exclaimed
Grace grinned at her Aunt, satisfied she had got her back for leaving her out.
