I awoke the next morning, the thunderstorm had passed and sunshine was now streaming through the window. I found myself snuggled with Marie in a spoon position, her back to me with my morning erection pressed firmly against her ass and a hand holding her breast. I turned to the clock to get the time: a little after 7 a.m. Marie felt me stir and turned slowly to face me.
"Morning," she whispered and tenderly kissed my lips.
"Morning to you too." I replied. "I thought for a moment that I must still be dreaming, holding a beautiful woman in my arms, but, if I'm still dreaming, I don't ever want to wake up."
Marie smiled and kissed me again, her eyes tearing up a little. We held each other for a few minutes, enjoying the closeness. Nature was soon calling us, so we both decided to get up and visit our own bathrooms. Marie got out of my bed and picked up her nightshirt off the floor. She flung it over her shoulder as she walked towards the door. I couldn't help but stare at her swaying ass as she walked away. Marie peeked over her shoulder and caught me staring.
"Haven't you had enough?" she laughed.
"Never!" I replied. "Some guys like tits or legs, but, I'm an ass man, and you have one of the nicest I have ever seen!"
Marie laughed and gave her rump a little shake. "Why don't you meet me in 10 minutes in the master bathroom. We can take a shower together, conserve a little water?"
I agreed without hesitation.
I went to my own bathroom to freshen up a bit. After brushing my teeth and shaving, I looked at myself in the mirror. Well, you're no longer a virgin, I thought to myself, and it was your own sister who initiated you. I grinned like a fool at my reflection and then headed for the shower and my sister.
The master bath was in our parents room. They had a rather large shower, plenty of room for 2 people to share. I heard the water running as I entered the room. I saw through the glass shower doors that Marie was already started without me. I opened the shower door and just stood there for a minute, enjoying the view. Marie was facing away from me, her hair hanging down her back, slick against her skin. The water glistened against her tan back and ran down to her untanned ass. The white of her butt contrasting nicely against her tan legs and back. Marie turned around to face me.
"Are you just gonna stand there all day or get in?" She asked.
"Just enjoying the view," I replied, "I'm coming."
"Well hurry up, it's getting cold," Marie said, looking down at her now erect nipples.
I laughed and got in and closed the door. I gathered up the soap and started to lather Marie up, covering her whole body with suds. I paid extra attention to her tits, and her pussy and ass. I took the detachable shower head and rinsed her off, noticing that Marie really seemed to like the feel of water pulsating against her pussy. I made doubly sure her tits were rinsed off by check them with my tongue, taking her nipples into my mouth. Marie grabbed some shaving cream and proceeded to lather up her legs for shaving. I never thought a girl shaving her legs would be so erotic! After her legs, Marie applied some lather to her pubic mound.
"Gotta get the bikini area too!" she said.
