I awoke the next morning in my sisters bed. Marie was already up and around, I could hear her moving around in the bathroom. I got out of bed and walked to the bathroom door to see Marie rummaging through the medicine cabinet. I walked up behind her and wrapped my arms around her naked body, my morning hard-on slipping between her ass cheeks.
“Good morning.” I said.
“It’s about time you got up, sleepy head.” Marie replied, wriggling her ass into my cock.
‘What are you doing?” I asked.
“I’m looking for my birth control pills.” Marie replied. “Ah, here they are, we have to be real careful Ray. I’m too young to be a mama, especially with by brothers kids. I don’t want to be raising any “Flipper” babies.”
“Yeah, I never thought about that. It’s something we don’t need.” I said.
“Right, I mean what we’re doing would be enough of a scandal if anyone ever found out.” Marie said. “Any babies that came from this would be subjected to a living hell for the rest of their lives, I’m not about to put any innocent child through that.”
I agreed completely with Marie on that point.
“You better get a move on, remember Laura is coming over in a little while.” Marie said. “Oh, and there is a surprise on the bed for you.”
I walked back to Marie’s bed to see a small package there. I reached in the sack and pulled out the contents.
“You want me to wear this?” I exclaimed, holding up a black thong swimsuit.
Marie laughed. “Yep, Laura picked it out and even paid for it, so I think she is gonna expect to see you in it. Try it on so we can see how it looks.”
My morning erection had started to wilt a little, but the thought of Laura wanting to see me in a thong had me at full hardness again.
“Uh, Marie, I don’t think its gonna fit with me in this condition.” I said, waving my hard cock at her.
Marie laughed. “Geez, you guys can get hard over anything, can’t you? Ok, sit on the bed and I’ll take care of it for you.”
I sat on the bed as Marie walked to her nightstand and reached inside, pulling out a tube of lotion.
“Let’s try something new.” She said, kneeling on the floor between my legs.
Marie poured some lotion on her hands and proceeded to coat my dick with it. She then rubbed some all over her tits. She leaned forward and placed my cock between her tits and used her hands to squeeze her tits together, trapping my cock between them.
“Now, this is called titty fucking. I’m sure you’ve seen it on those porno’s you watch all the time. Just relax and let me do all the work.”
Marie started to move up and down, my cock slipping through the valley of her tits. It was an incredible feeling, the lotion eased the passage, and I was soon fucking her tits as hard and as fast as I had fucked her pussy the night before. Marie would lash at the head of my dick as it emerged at the top of every stroke, and every so often, she would stop and suck the head in her mouth. After a few minutes of this, I was moaning and on the verge of cumming.
“I’m cumming Marie.” I groaned, and started shooting my cum all over her upper chest and neck. Marie kept pumping until she had drained every last drop from me. She took my softening cock in her mouth to clean any remaining cum off me.
Marie got up and went back into the bathroom and soon returned with a wet wash cloth and a towel. She cleaned the both of us off and then smiled and handed me the thong.
“Now try it on.”
I stepped into the thong and pulled it up my legs. The front pouch covered my cock and balls snuggly and the thin strap slipped between my ass cheeks.
Marie smiled with approval. “Bend over and let me show you how to adjust the back. You lean over and slide your finger underneath the thong like this.” I felt her finger slide under the tong and between my cheeks. “Now you lift and guide the strip into place with your finger.” I felt her finger slide through my crevice, over my asshole and come to rest against my balls. “Just like that. Now turn around and let me see the front.”
I turned around and Marie looked me over. She frowned and I followed her gaze to my crotch. The pouch fit well enough, but there were tufts of hair escaping from the edges.
“Looks like were gonna have to do some trimming.” Marie told me. “You go shower, and when you’re done, come see me and I’ll take care of your bikini zone.”
I took a leisurely shower, dried myself off and headed back to Marie’s room. She too had just showered and was still nude waiting for me. She had grabbed dads beard trimmer and motioned for me to sit on the shower bench.
“Now, I’m gonna trim you down until you’re almost bare before I start shaving.” Marie said.
The hum of the trimmer soon filled the room as my sister went to work. She was true to her word, after a few minutes I looked almost like a child down there. Marie grabbed the shaving cream and soon had my entire crotch covered.
“Now hold still.” She ordered. I don’t want to castrate you.”
Marie soon had the hair above my cock shaved into a nice neat patch. She then took my dick in her hand and held it up against my stomach as she shaved my inner thighs.
“Now you’re really gonna have to hold still, I’m gonna remove any stray hairs from the shaft and then I’m gonna shave your balls clean.”
I held my breath as she worked the razor down my shaft. Marie then gently and slowly shaved my balls until I was almost as hairless as a new born baby. She then had me turn around and spread my ass cheeks. A few quick strokes later, she was done.
Marie smiled at her handy work. “Jump in the shower and rinse off, then we’ll try the thong again.”
A few minutes later, I had the thong back on and we were both happy with the results.
“Perfect.” Marie said. “How does it feel?”
A little weird at first.” I replied. But now I can hardly tell it’s there. It’s really comfortable.”
“Good, now get out of here and let me get ready.” Marie said. “Laura will be here soon.”
I went out to the pool and stared to get it ready for the day ahead. I skimmed the leaves off with the net, and then started to vacuum the bottom.
Laura must have turned up right about then, cause I heard a whistle of approval and turned to see Laura and my sister standing there.
“Looking good Ray.” Laura called out to me smiling.
