Marcie was two years older than me as I was seventeen. Her biological dad and mom were Cherokee. I am whiter than white as I am of Irish and Scottish descent. I have red hair and freckles. Black-rimmed glasses surrounded my dark blue eyes.

Marcie had large, heavy breasts with large dark areolas. Her nipples were short and thick. Being an American Indian, Marcie had no hair. I know this as she would walk around the house naked to piss off our dad and my mom. Her mom is in prison for selling drugs. My dad abandoned me and my mom when I was six, and we haven't heard from him since.

Marcie was an angry child and teenager. She used to pick on me mercilessly. Now that I've matured into a big strong teenager, her digs have slowed down to occasional teases, and we have become closer.

Marcie has had many boyfriends, and I have heard them fucking through the wall. I masturbated a lot and was a virgin. I had only kissed one girl, and that was in the fifth grade.

I was stroking my cock while spread across my bed one night. I had my headphones on, listening to an audible porn story. I felt a breeze rush across my body as Marcie had my door wide open watching me arch my back as my fist pounded my cock.

I quickly pulled the covers over me. Marcie came in and shut the door. "It's too late to hide, bro. I saw you jerkin your gerkin," she laughed as she pulled my covers off my body. "That is a big, beautiful cock." Marcie grabbed a ruler from my desk. She pulled my cock straight up and measured from my pelvis to the tip of my cock. "My God, bro, you have a nine-inch cock, and it's fucking thick. Let me finish you off."

Marcie was just in a bra and sleep shorts. My cock deflated a bit with my shock and embarrassment. She said, "Let me help you out." She unhooked her bra, and her firm, heavy breasts fell out. She used two hands to grip my cock and stroked me at a slow, even pace. "Touch my tits," she ordered. Her hands sped up, and the head turned purple. She was panting, and her breasts were bouncing. I squeezed both globes and rubbed her nipples with my thumbs.

"Oh, shit, Marcie!" I screamed. My cum shot into the air and came down on her neck and breasts. She kept pumping until I stopped spurting. Marcie kissed me on the cheek, picked up her bra and walked out my door.

Two nights later, around midnight, Marcie came into my room already panting. "Take out your cock and stroke it until you cum." I pulled out my flaccid cock and started wanking. She pulled off her sleep shirt and stood there with her legs spread and not wearing anything. My cock grew to full length. "Damn, that is a big cock," she gasped.

Marcie inserted two fingers fully into her bald cunt. She wildly fingered herself. She grunted and stared at my cock. She started whimpering as she couldn't make herself cum. Her eyes were wild, and her breasts rocked as she plunged into herself.

She was so fucking sexy. My load shot into the air and pooled on my stomach. Marcie growled in desperation and rushed to the bed and climbed up and squatted over my face. Her juices dripped into my mouth for my first taste of pussy. "Lick my cunt and suck my clit," Marcie half begged and half ordered.

Her wet pussy plopped on my face, and my tongue darted deep into her pink. I knew enough from watching porn to move to her clit. Her clit was easy to find as it was as big as a grape. I sucked it fully into my mouth and worked my tongue over it.

"Yes, fucking yes. Oh God. Right there, bro. Shit, I'm going to cum," Marcie screamed, her legs shook, and I felt her pussy quiver on my face. A river of creamy fluid poured out of her cunt onto my face and into my mouth. Marcie held on to the headboard until her body quit spasming. She dismounted my face and staggered out of the room.

A week later I walked by the hall bathroom and peeked through the crack in the door. Marcie was in the garden tub soaking. Her fabulous tits were floating above the water. She had her eyes closed and her mouth open. It was obvious she was masturbating under the water. I snuck in and pushed my pants and boxers to the floor.

My semi-hard cock tapped her cheek. She opened her eyes and squealed, "Oh yes, bro, give your cock." Her lips surrounded the head, and her tongue twirled around the rim. My cock grew in her mouth as she took more of it in. She bobbed her head on my shaft, gagging and gurgling. She didn't come close to taking it all, but her warm wet mouth surrounding my cock was the best feeling I ever had.

My hands grasped her hair, and I fucked her face as she looked up at me with watering eyes. Her mouth was soft and warm, and my cock slid in and out of it vigorously. My cum blasted out, spraying her face, neck, chest and tits.

"Your cock is amazing, bro. It felt so good sliding into my mouth. Your cum is so salty and creamy," Marcie panted. "I came twice as I sucked you and fingered myself."

"Marcie, how about you don't call me bro during sex? You can call me Kirk, you know," I requested.

Marcie sank down under the bubbles to wash my cum off. "Okay, bro," she giggled as she sank underwater.

I had been away at band camp for three weeks. I was horny as hell as I couldn't masturbate or get relief from Marcie. Marcie picked me up at school. I loaded all my stuff into her car. "Where's Mom and Dad?" I asked.

Marcie replied, "They are gone on a couple’s retreat for the weekend and won't be back until late Sunday night." As we drove home, Marcie whipped out her tits and said, "Pull out your cock and jack off. I missed that cock of yours, bro."

My cock was immediately hard as I ogled her beautiful breasts. I slowly stroked my cock from base to tip, squeezing out pre-cum from the head. Marcie swiped the liquid off with her finger and sucked it. She squirmed in her seat as my stroking sped up and my grunting got louder. I threw my head back and splashed my cum all over her dashboard.

Marcie walked into the house with her breasts hanging out of her blouse. She pushed me into our parents’ bedroom and undressed me. She shed the rest of her clothes. She was standing in front of me, panting, with her legs spread.

"Kirk, I have got to have you inside me. Do you have a condom?" Marcie asked.

"No, I never had use for one. You know I have never had sex," I said.

Marcie had a wild look on her and shouted, "Fuck it, lay down on the bed." I got on my back with my hard cock lying on my stomach. Marcie straddled me, and I licked her nipples as she bent forward. "Oh God, Kirk, I'm so fucking excited." She grabbed my cock and placed it at her pink entrance. She was already dripping and shaking. She sank down, letting the head pass through her opening. "Oh, you are stretching me. Fuck your cock is big." Her wet and warm pussy felt so good sheathing my cock head. She wiggled further down as she gasped for air. Her velvet walls slid over my shaft as I grabbed her hips, digging my fingers into her flesh.

Marcie's eyes rolled up in her head as I watched my cock get sucked up into her tight cunt. No hand or mouth could ever feel this good. Marcie cried because her senses were overstimulated. She had to pull up and then push back down so that her pussy could devour my cock. After about five minutes, she sat fully on my pelvis. "Kirk oh Kirk. I'm going to cum, oh shit fuck it is so good," Marcie cried out. Her body shook, and she moaned. I felt warm fluid pour out onto my body.

She bounced on my cock like she was pumping oil out of the ground. The friction she was causing was going to make me erupt inside of her. Marcie was full out screaming gibberish by now. She was having multiple orgasms, making a mess of our parents’ bed. My cum exploded deep inside her. She gasped as she felt my seed spread around inside her.

Marcie collapsed on my chest. My cock slowly eased out of her swollen pussy as she moaned, "That was the best fuck I ever had. Your cock stretched me so wide, I couldn't stop cumming. I'm not even worried that your seed is in me."

Marcie held my face and kissed me for the first time. Our tongues tangled with each other as our mouths made love.

After about an hour of cuddling and me sucking her glorious tits, Marcie popped up on all fours with her meaty ass in the air. "Fuck me from behind," she insisted. She didn't have to tell me twice. Her asshole perched above her pussy looked incredibly sexy, and I was amazed. I gave it a quick lick, and Marcie squealed. My cock pushed into her opening, and I sank my shaft fully into her cunt from behind. "Oh, God!" she screamed. I pounded her from behind as our slapping flesh filled the room with loud clapping. She grunted with every thrust. She was tighter from behind, and the view of the curve of her waist forming into her sweet hips and ass set me off. As soon as my juices splashed onto her cervix, Marcie came again. I stayed inside her, letting my cock shrink out of her. We both thoroughly enjoyed that sensation.

We showered and had dinner. Well, pizza and wings that we had delivered. We sat on the couch, hugging and kissing as we watched TV. I was falling in love with Marcie.

Around midnight, we retired to her bedroom. We crawled into the missionary position, and she wrapped her legs around my waist. We kissed passionately as my cock pushed into her pussy. We slowly made love, both of us moaning for over thirty minutes. Marcie had a calm, sweet climax. I spread my seed inside her after her climax.

"Kirk, you make me feel complete. When I'm near you, I feel safe. When you are in me, I feel one with you," Marcie whispered.

We fucked on all three beds that weekend. We were experimenting with me trying to insert my cock into her ass when our parents walked in on us Sunday evening.

Marcie and I moved out after I graduated. I had won a full scholarship to Auburn. We lived in the couples dorm. During my four years at Auburn, I did successfully penetrate Marcie's ass a few times, and we had two kids.

We were married a month after I graduated, and I got a great job. We moved into an enormous house in a wonderful neighborhood. We eventually had two more kids. All four were girls and looked just like their mother.

We are empty nesters now, free to fuck at anytime and anywhere.
