Sorry for the formatting on P1, it was copy and pasted from Google Sheets. Even though it showed correctly on my side it posted in one paragraph. I’m still working on fixing it.

I was the last one up the next morning. I walked in the kitchen to Abby making a grocery list.
“Good morning, hun. I’m going to run out and grab some groceries and I’ll grab breakfast while I’m out and bring it back for the three of us.” She greeted.
“Oh okay, that sounds great. Thank you.”
“We’ll it’s just a thank you for taking care of little man all night last night. You must be tired.” She said, and kissed me in thanks.
“Is Campbell up yet?” I asked, hoping I wouldn’t have to deal with the awkwardness of the three of us being in the same room immediately after waking up.
“You know, it was the weirdest thing. She woke up and asked if she could borrow a razor because she forgot hers, and she’s been in the bathroom for over an hour now.” Abby told me, confused at her sister’s absence. I had an idea of what was taking so long.
“She probably was just wanting to take a swim, but hadn’t shaved her legs recently. You know how she gets sometimes.”
“That’s probably it.” She agreed.
I heard Abby tap on the guest bathroom door and ask Campbell what she wanted to eat. She came back in and told me she would be back in about an hour and a half, grabbed our wild man of a son, and took off to the store.
With Abby gone and it just being Campbell and I, I wanted to straighten out that last night was a one time event, but I also didn’t want to go barging in the bathroom. I sat down with a book in the living room. The natural light of the morning filled the room through the windows on the front of the house. I hadn’t been reading for two minutes when I heard the guest bathroom door open and Campbell come out. She went to the kitchen first before finding me in the living room. She was tearing a silk robe that I remembered her parents getting her and Abby for Christmas a couple of years back.
“Listen, Campbell…” I started before being cut off.
“So, after you left last night I googled some things and I’ve decided what I want us to do next,” she interrupted.
“Cam, there can’t be a next time,” I began my speech just as I had rehearsed in my head.
I heard something hit the floor. I turned my head from looking out the back windows from the morning sun glistening on the river to see that the robe had hit the floor. My eyes made their way up freshly shaved legs to a completely smooth pussy. Her small B cups with the sun shining through looked so inviting, her nipples poking up in the air conditioning from where we keep it cooler at night. She was standing there like a goddess with a smirk on her face that showed confidence that I hadn’t seen in her before.
“Campbell, we can’t.”
“Your shorts are telling me otherwise,” she smiled at my erection starting to show itself. She started walking towards me. “Like I said, I got on Google last night. People do shave down there, so I shaved myself smooth for you. I also watched a few videos and I’m going to suck your dick and you’re going to eat my pussy.”
I was too in shock to hear this once so innocent girl talk like this to stop her from straddling me on the couch. Our lips touched, our tongues met and slid together as if it were the millionth time we had done this. She lowered herself down to where I could feel the warm moisture of her pussy on my stiff cock through the same gym shorts from last night.
We made out passionately for what seemed like several minutes but was just a brief moment. She moved her soft lips to my neck and up to my ear. I gasped for air, she had found my spot. Her teeth nibbled at my ear lobe as she moaned.
She whispered into my ear, “I want you to cum in my mouth.”
I had had it. I slid my hands under her ass and stood up. She instinctively wrapped her legs around me as she continue to kiss my neck and ear. I carried her straight into the guest bedroom and laid on her on the bed. Our tongues met and danced for another moment before I moved to her neck. She was the one gasping for air this time. I moved from her neck down her chest to her left nipple and began to playfully lick and nipple, as I slid the right one between my index and middle fingers. Her breasts were firm from her years of working out and high intensity soccer training. I loved that about her. She audibly moaned from the first time she’s had her nipples sucked. I swapped between her tits for a few minutes showing both of them equal love before kissing her abs sensually as I lowered myself down to give her what she wanted.
I positioned myself between her legs and draped her legs over my shoulders. I noticed a damp circle below her from where her juices had started to collect on the sheets. My first lick ran the full length of her slit in an attempt to collect all of her juice that I could. She tasted so incredibly sweet. She arched her back and let out a moan, or more of a scream. She was so very sensitive. I used the point of my tongue to massage her clit while I used my index finger to put slow pulsing pressure on her vagina, as if to tease penetration.
Her moaning was satisfaction in enough for me. I was more turned on than I have been in years. I slowly got faster and the arch in her back got higher. I finally inserted my finger and continued my work on her clit with my tongue. Her moaning and breathing got faster and heavier, until I felt her climaxing. Her legs were shaking, I was fingering her as fast I could from the position I was laying, and my tongue was working overtime to make the orgasm last as long as possible.
“Oh my God,” she moaned as the orgasm subsided, “that was amazing. You are so good at that.”
“That’s my favorite thing to do, so I’ve gotten good practice.”
“Now it’s your turn,” she said sitting up from the sheets soaked with her sweat and juices.
She got up, grabbed my hand, and pulled me up as well. She kissed my neck, my chest, and slowly worked her way down my abs. As she bent over to kiss my abs, I could see the rear profile of her perfect asshole and pussy from the mirror on the dresser, and it gave me an idea.
“I’m so glad you keep in shape. Your baseball years really did you good,” she said rubbing her hands across my abs.
She finally knelt down to face level with my cock which, like last night, was standing almost straight up. She kissed my shaft, which I almost didn’t feel because her lips are so soft. She raised it straight up and licked from base to tip, then repeated this on each side. She looked and smiled before opening her mouth and sliding it in. She only made it about halfway before coming off it.
“You are so big. I’m going to have to try harder to take the whole thing.” She said looking up at me.
“You don’t have to take the whole thing. This is your first time.”
She winked at me as she opened up again and took 3/4 of it this time and one more time back down she had the whole thing. I heard the gulping noise that comes with the gag reflex being activated and I knew my head was in my 18 year old sister in law’s throat. She slid me in and out of her throat easier than I would have thought possible for her. When I was all in her mouth I could feel her working me over with her tongue. She took her free hand gently grazed the backside of my balls while let her tongue do the work on my shaft. This drove me wild and it was all I could do to keep myself together. She slid me into her throat one more time before working me with her hand and tongue at the same time while the other hand cupped my ball sack. I couldn’t hold it this time and started releasing my cum into her mouth. I gave at least seven good pumps and didn’t see a drop come out.
“You really did get on the internet and do your research,” I said, breathing heavily
“You don’t become Valedictorian without doing your research,” she gave me a wink.
“I bet you didn’t find this in your research,” I told her as I helped her up off her knees and turned her toward the bed.
She had lifted a leg to climb back in the bed when I pushed her down forcefully in the middle of her back, bending her over the bed. She let out a yelp of surprise, but didn’t object. I spread her legs, resting my cock that had just been drained in her ass crack, as I kissed her neck and down her back until I knelt in the floor. I then alternated kissing each leg higher until I got to her pussy. Her legs being spread gave me the perfect view of how tight she was and he cheeks spread by themselves to show me her perfect little rosebud.
I proceeded to stick my tongue in her vagina and tongue fuck her, like I didn’t get to earlier. I kept at this while gently rubbing her clit with my finger. I felt her second orgasm building and pulled away completely. I couldn’t let her finish that quickly. She was breathing heavily, her hands by her head grasping the sheets. I started rubbing her slit again gently with one finger. I inserted my finger in her and began fingering her from behind. Her writhing continued while her moaning intensified.
I couldn’t take it anymore, I dove in tongue first to her asshole, starting gently for her to get used to the sensation and then building the intensity. I felt the orgasm coming back, this time I embraced it and slipped a second finger in her tight pussy and sped my tongue up moving up and down on her hole. The orgasm last every bit of 30 seconds as I maintained everything I was doing. I pulled my fingers out and gave one last lick from clit to asshole.
“You’re right, I didn’t find that in my research.”
I laid down beside her and kissed her. We had started something and I was concerned with where it was headed, but it was damn good right now.
