Pounding on the door woke me along with Kathy, shaking me. I had my arm over her, and she was trying to get out from under it. I raised up and yelled, “OK, Mom, I’m awake.” Kathy scampered bare-butt into her room and called to Mom when she knocked. I flopped back down and fell asleep until Kathy shook me awake again. She had finished her shower and looked bright and fresh. I loved the way she looked when her hair was wet and framed her face. I looked into her eyes and pulled her down on me for a kiss. It was wet and warm, her tits cool on my chest. She wiggled out of my grasp and told me to get ready. I grumbled and said I wanted more kisses. She gave me a peck on the nose and said later. She scampered off to her room as I watched her butt jiggle and her tits bounce. I stumbled into the shower and managed to awaken a little. After brushing and shaving, I dressed, gathered my books and papers, and went down to breakfast. Mom was normal, and I munched breakfast as she finished the paper with her coffee. Kathy bounced in as I was finishing. Her cheeks were flushed, and her eyes bright, that well-fucked look.

“My! You are chipper this morning!” Mom commented lightly. Kathy raised her eyebrows, and her eyes twinkled. She sat down to eat. I ducked my head down and finished my cereal.

Nothing of note occurred until Chuck and I walked into Miss Monroe’s room. She walked to the front of her desk like normal, carrying a couple of sheets of paper. After we sat, she leaned forward and handed them to me. Her bra was so low-cut I could see her nipples! My cock sprang to attention in seconds, and I couldn’t breathe. I’m sure I must have gasped out loud. She stayed like that as she told me she had two forms back already, from girls she knew. I stared at her tits and glanced to her eyes and back to those tits. It was the sexiest bra I had ever seen! Her nipples looked as if they were being served up for kisses! Staying bent over, she glanced at Chuck. He was leaning toward me so he could see them better. His mouth was open, and he was licking his lips. She smiled at him and twisted a little toward him so he could see them better. Her chest was getting flushed, and the nipples seemed to be getting bigger. She turned back to me and asked, “What do you think?”

All I could manage was, “Beautiful!”

She raised back up and said softly, “Glad you approve. Now what do you think of the forms?” I laughed and tried to remember what she was talking about. Oh yeah! I had them in my hand. I blushed and looked at them. One was from Trina Munson, a foxy senior, and the other was from Maryanne Langley, the Senior Class President and numero uno babe! Their mothers’ names and phone numbers were on the forms.

I handed them to Chuck, and he said, “Wow!”.

“I know their mothers, and I’ve already talked to them. Call tonight and schedule your measurements. Now check the servers and get to class.” We both stood, our hard-ons evident. She looked and smiled at us.

“Just to keep you sharp today.” She leaned forward and displayed her tits again. Chuck and I both groaned, and she raised up laughing. I had to straighten my cock out, and I didn’t hide it from her when I positioned it against my belly. She looked into my eyes and pursed her lips. I groaned again and turned away. I was going to rape her if I didn’t leave now! When we left, she blew me a little kiss again. Damn! Damn! Damn! She was hot!

In the hall, Chuck was rambling on about her bra. I had to shush him before somebody overheard. After school, we picked up Kathy and headed home. On the way, Chuck whispered something to her. She laughed and whispered back. I asked what the secret was, and Kathy said it was a secret. Chuck was blushing.

Chuck had to go home for chores since he was going to be at my house all weekend. When we got home, Kathy ran up to call her friends. I called and left a message for Mrs. Munson to call me back about my science lab project. Next, I called Mrs. Langley, and she answered. We had a nice conversation, and I asked when I might come over for the measurements. She said she was available now if I wanted to come over. I got directions and yelled to Kathy that I was going over to the Langleys. I loaded the gear in the car and was on my way.

They lived in one of the upscale developments in town that my Dad had started. I parked in the drive and hauled my equipment to the door. She opened it before I rang the bell. She was a striking woman. It was obvious where Maryanne got her looks. She was about 5’ 10” tall and she was wearing a dark blue dress, the tops of her tits showing. The dress was well above her knees and she had the legs for it. With her high heels on, she was as tall as I was. She ushered me through a foyer into a family room off the kitchen. I explained the project as we went. I hauled in the frame, then the chair, and set them up. She asked if I would like a drink, and I asked for a Coke. She swayed over to a small bar and fixed me a coke with ice, a scotch, and water for herself. She walked to the couch with the drinks and invited me to sit down. I sat, and she sat beside me. The dress moved way up her thigh when she crossed her legs and left little to the imagination. We talked for a long time, and she was really nice. Despite her looks, she wasn’t stuck up, and she seemed genuinely interested in the project. She talked about my Dad a little, and we talked about Maryanne. I managed to mention that it was obvious where Maryanne got her looks! She smiled and thanked me. Her leg was rocking a little after that. She finished her drink and asked if I wanted another as she went to the bar and poured herself another. I told her I had plenty left. When she sat down again, she was a little closer to me, and our knees touched briefly when she turned to talk. I asked her if she had a job, and she said she was a partner in a boutique at the Mall.

“That explains why you are dressed so well.” I said it sincerely and meant her to understand that I wasn’t being inane. She brought her hand up to the top of her breasts and touched them. She colored slightly and, still touching her breasts, thanked me for noticing.

“Mrs. Langley, you are very easy to notice. I think you are a truly beautiful woman and very nice to talk to.”

She blushed and kept her hand to her breasts. Her leg was moving faster as she said, “It’s nice to know someone notices, and thank you. It’s been a while since I’ve had a nice compliment.”

I leaned toward her till our knees touched, and touching her knee with my fingertips, I told her I thought she was a hot-looking woman. Her hand came down on top of mine lightly, and she held it there.

“Mike, you make me blush!” She more than made me blush; she made my dick hard! She was leaning forward, and I could see more of her breasts and no sign of a bra. She kept my hand on her knee, and it seemed to get hot. My chest was tight. She asked if I was dating, and I told her the truth. I didn’t say anything about fucking. She thought I should be, and I told her I was pretty shy around women. She told me I didn’t have to be and pulled my hand a little higher up her leg. I took a little initiative, and leaning more toward her, I pushed my hand up her leg another inch.

“Mrs. Langley, may I kiss you?” I whispered it. I was dreading her rejection.

“Mike, I’m flattered! Yes, you may.” Keeping my hand on her thigh, I leaned to her and kissed her softly. The kiss lingered, and she sucked my lower lip between hers. Her hand over mine pressed warmly down, and her free hand came to my cheek. She released my lip, and we parted a few inches. I was breathing harder, and her breath was brushing lightly across my face. Her eyes were bright as she looked into mine.

“That was wonderful, Mrs. Langley. May I kiss you again?” Her lips parted, and she pressed toward me again. This time, the tip of her tongue brushed over my lips, and I returned the favor. I started my tongue slightly between her lips, and the tip of her tongue met mine. The tips played lightly with each other, and her breath quickened. She pulled my hand up her thigh a little, and her hand on my face cupped my chin and pulled me into a deeper kiss. Her lips opened, so I sucked her lower lip between mine and pushed my hand higher up her thigh. She squeezed my hand a little, and I moved my thumb down to brush her inner thigh. She uncrossed her legs but kept my hand in place. I pushed it further up her thigh and encountered the hem of her dress taut across her thighs. Now the kiss deepened to another level, and her tongue snaked into my mouth. It was long and thin, and she moved it slowly. I reciprocated by moving mine slowly over and under hers. She moaned a little, and my hand slipped between her thighs to the crotch of her panty hose. There was dampness there as I stroked my fingertips over her pussy. We kissed, and I slowly stroked her pussy for a few minutes. She broke the kiss and looked at me with very bright eyes.

“Would you like to fuck me, Mike?”

“Oh yes, Mrs. Langley!” I was gasping and almost dizzy. She clasped her thighs on my hand and said, “Come with me.” She stood, took my hand, and pulled me to the hallway, then upstairs. We went into a huge bedroom suite and up to a king-size four-poster bed. She turned her back to me and told me to do her dress. With shaking hands, I ran the zipper down to the crack of her ass. Lo and behold! No bra! Just soft, bare back! I pushed the dress off her shoulders. Holding her shoulders gently, I kissed them and the back of her neck. She smelled and tasted wonderful. She rolled her head back as I kissed her neck. And her arms dropped as the dress fell to her waist. I ran my hands down her arms, then I cupped her breasts from behind. They were very wide at the base and firm. They were not as full as Annie’s and a little smaller. Her nipples were small too. I pinched the nipples between thumb and forefinger, rolling them gently. She brought her hands up over mine, holding them to her tits while I rolled, pinched, and pulled her nipples for several minutes. I was pressed to her back and kissing her neck. Her ass pushed back against my cock. She was quiet while this was going on. She dropped her hands to her hips, pushing dress, panty hose and panties below her butt. I brought my hands down her stomach over amazingly soft skin to a mons without hair! Her pussy was baby-soft, smooth, and definitely wet.

“Wow!” I whispered in her ear. She giggled and pressed my hand to her pussy. I stroked it lightly, while she tipped her head back on my shoulder, while my other hand pinched and pulled her nipple. We stood like that for a few minutes, then she turned from me and sat on the edge of the bed. Her body was perfect! There were no wrinkles, sags, or marks! “Wow! Mrs. Langley, your body is perfect!” Her pussy was just like the rest of her skin. She pushed her clothes off her legs and told me to hurry. I stripped in record time, and she watched as my cock appeared.

“You have a lovely cock, Mike!”

“You have a lovely pussy, Mrs. Langley! May I kiss it?”

“Oh yes!” She gasped as she scooted up on the bed and laid back. I climbed up beside her, knelt over her, and kissed her soft, smooth tummy. She purred and stroked my hair. I moved lower and kissed her mons where there should have been hair, instead just soft, smooth skin, no stubble! I moved lower and she parted her legs. Her pussy lips were soft and full. There was no sign of her inner lips or clitoris. I licked over the outer lips and moved around till I was between her knees. I kissed her outer lips, then using my thumbs, I spread her pussy lips apart. It opened like a flower with a bright pink center. The smell was wonderful and fresh. This woman took good care of her body! I leaned in and gave her little licks, sucks, and kisses all over her pussy. As I neared her clitoris, it popped out about an eighth of an inch. Her fingers were still running through my hair until my tongue brushed her clit. She jerked, moaned, and her fingers pulled me to her. I licked her clit on the sides, then under it and above, but never on the end.

“Oh Mike! Don’t tease me so! Please kiss it!” I relented and sucked it between my lips. I was able to pull it in like a nipple as I nursed it and licked the tip. She went wild! Her quietness ended, and she started chanting to me to kiss it, suck it, bite it, lick it, and every other thing you could ever do to a clit! I ran two fingers into her soaking wet cunt and felt along the top till I touched the orange-peel tissue. I stroked it with my fingertips, sucking her clit, and she erupted! She was shouting, “Oh fuck! Oh shit! Fuck me, baby!” On and on at the top of her lungs. I’m sure the neighbors might have heard. She thrashed like that for several minutes and then pulled me up on her, telling me to fuck her hard. My cock slid in, and she was away! I just held on as she fucked me! Her cunt was amazingly tight, and it gripped me tight. My cum started up fast, and I shot into her within a few minutes. She didn’t slow down. She was bucking and swearing, and I tried to stay in her. It was wonderfully exciting, and my cock stiffened again in minutes. I started hard thrusts into her when I figured out her crazy rhythm. She kept up the yelling, and I kept up the fucking. This time I lasted a lot longer, and we were lathered up like racehorses. Her pussy was sucking and squishing as I pounded her. She was clasping my ass, and her heels were there too. Her yelling was incoherent when I finally felt my second cum start. I took control of her ass and mindlessly fucked her. At last, I blew cum into her cunt, so hard that it must have reached the back of her eyeballs. When I finished, I fell back on the bed by her feet. I lay there gasping for breath for several minutes. I looked up toward her pussy. My cum was drooling out of her onto the crack of her ass and onto the bed. It was sexy to see that smooth pussy drooling cum.

“Mrs. Langley, your cunt is beautiful!” She ran her fingers down through the mess, and it was neat to see those long, slim fingers with long red nails smear cum over her pussy. She smeared it around for a couple of minutes and moaned softly. I crawled up the bed to lie beside her. She looked at me with soft, green eyes and smiled as she continued to stroke her pussy.

“Mike, that was beautiful. I haven’t had sex like that in decades! I can’t remember the last time my orgasms rolled on like that! You filled me up with semen, and it feels lovely! You are a lovely boy, and I could hug you forever. She threw her free arm around my neck and pulled me in for a long, sweet kiss. I stroked her nipples lightly as we kissed. She groaned.

“God, I’m still having little orgasms!” At last, we broke apart, and she told me how her husband hadn’t had sex with her for months. I asked if he was impotent, and she said he might be or he was getting it elsewhere. I told her if he was fucking someone else, he was nuts! She laughed and kissed me.

“We had better get dressed and be downstairs before Maryanne gets home.” She pointed at her bathroom, so I went in and washed off, dressed, and went downstairs, while she cleaned up and dressed. When she came downstairs, she was dressed casually, and you couldn’t tell we had fucked our brains out. She was elegant and sophisticated. Who would have thought?

She sat in the chair, and we managed to get it done in spite of a lot of verbal sexual teasing. She was very witty and fun. Was I falling in love with every woman I met? Just as we were finishing, Maryanne came in through the kitchen. Seeing her beside her Mom was quite a sight. She was almost as tall as her Mom, but her body was more filled out. Her tits were bigger, and her hips a little more rounded. She was built like Kathy, just taller. She was interested in what I was doing and asked lots of questions. She understood all of the math terms and the analysis. I showed her the forms I had filled out on her Mom and the plots I had done of Kathy and my Mom. She compared them as I had done and was very interested in the results. I explained that her mother was just the fourth subject, and we had a long way to go. She had time, so she sat while I measured her face. Her eyes were flirty as I worked, but nothing happened with her mother close by. When I finished, I promised to bring the plots over and show her. She excused herself to go change. Her Mom helped me carry my stuff to my car. When I finished, she pulled me inside the front door, gave me a quick kiss, and a warm thank you. I thanked her and asked if I could call from time to time to see how she was. Her eyes twinkled, and she said she would love it. On the way home, I realized Maryanne was the first woman measured that had not been fucked by Chuck or me. Were we slipping? Wait! Mom was the only one I hadn’t fucked! Maybe there were some other factors at play here.

I arrived in time for dinner, and Mom asked about the session. I showed her the measurements and remarked that Mrs. Langley and Maryanne were very much alike. Kathy asked if Chuck was still coming over, and I told her Friday and Saturday. She gave a coy look at Mom, and Mom just ignored her. After dinner, we went up to my room to study, and I told Kathy that we might want to get out of the house tomorrow night for a while.

“Yeah. I don’t think I could stand a whole weekend of them locked in the bedroom smacking bellies!” Her nose was wrinkled.

“Could you stand a whole weekend of us smacking bellies?” I said it with a smirk.

“Now that would be cool!”

“Then how are we different?” She smacked me on the head.

“Well then, how about a movie? A brother/sister date? You and I sitting side by side for over two hours without kissing, rubbing tits or cock, or doing anything that is illegal. Could that be fun?” I had her cornered.

“Yes, it could be fun! We can’t be always fucking like bunnies!” Damn!

“Why not? I like fucking. I especially like fucking you. You are a sexy bunny!” I was trying to be serious.

“I love being your sexy bunny, Mike, but most people wouldn’t like either you being my fuck bunny or me your fuck bunny. So if we can’t always be fuck bunnies, we can go to a movie.” She had me there. Who can argue with circular logic?

She went into her room, and I entered the coordinates for the lovely ladies Langley. Sure enough! They were almost identical. I entered them in the spreadsheet, and something strange appeared. The Langley ladies were within 2% of each other and Miss Annie Monroe! As I thought about it. They were similar looking, although the Langleys were taller by about 5 inches.

Mom’s phone rang, and Mom called me to pick it up. It was Mrs. Munson. We talked for a while about the project, and she seemed interested. I asked when she would be available, and she said Monday afternoon. Trina wouldn’t be there, so I would have to schedule her separately. Oh well.

I wanted to call Annie, but I figured my sudden use of the telephone might be suspicious. I would see her in the morning. I pounded the books and checked on Kathy. She was still studying, and I didn’t bother her. I laid down on my bed, and the next thing I knew, Mom was pounding on the door to wake me for school. I was still dressed, and Kathy had thrown a blanket over me. I loved that girl. A minute later, she stuck her head in the door and, bare-ass naked, said, “It’s shower time, stud. Bring a condom. This fuck bunny is horny!” We had a very refreshing shower together, and I filled the condom. She wasn’t horny when I went down to eat.

Mom was a little more animated this morning. Was she anticipating an orgy with Chuck tonight? Kathy bounced in with flushed cheeks and bright eyes. I wished she wasn’t quite so vivacious after she had been fucked. Mom was going to figure it out someday.

We picked Chuck up, and he threw his weekend clothes in the back. Kathy teased him that he probably wouldn’t need clothes. He smiled and whispered something to her. She shrieked out, “Let me see it!” He told her maybe later. She tried to wheedle whatever it was out of him, but he was steadfast. Now, Chuck and I had very few secrets from each other, so this one must have something to do with Mom.
