Chapter 2

A week before Thanksgiving break, Miss Monroe asked Chuck and me to compete in the science fair.

“Use your computer knowledge to test a theory or demonstrate a scientific fact”, she said. We had to come up with our ideas before Thanksgiving. When Miss Monroe asked me for something, I would have walked through Hell to get it. Our personal priorities for the project were women, computers, and science last. Two days later, I came up with the perfect project. Computer Assisted Drawing (CAD), geometry, genetics, and women would be the subject. We prepared our outline and presented it to Miss Monroe the next day.

We proposed a research study to determine if the geometry of female heads would show any genetic similarities. We would use a CAD program to plot 3-dimensional models of various women and see if genetics had a bearing on any geometric similarities. Guess what our real motive was? Miss Monroe thought it had merit and told us to give her a test case sample after Thanksgiving break. We had one and a half weeks.

We copied the school’s CAD software onto my PC at home and started laying out the data collection procedure. One of our criteria was that only good-looking girls, their sisters, and moms would be subject material. I discussed the procedure with Mom, and she was very interested and said she and Kathy would help. Boy, was this going to be fun!

Chuck and I built a wooden box-type frame that would surround a person’s head while the subject sat in a chair. We stapled Mylar graph paper on two adjacent sides of the frame and affixed a simple wood headrest to an old kitchen chair. Mom and Kathy would be the test subjects.

Mom was at work, so Kathy was first. We bought her out to the garage and sat her in the chair with the back of her head against the rest. It forced her to sit very upright, and she looked awesome with her tits thrust forward and up. Chuck was so nervous he was almost stuttering. We turned out the overhead light and turned on a floor lamp so Kathy’s shadow was cast against the Mylar graph paper on her right. Chuck touched the tip of Kathy’s nose with a pencil, and I started writing down the coordinates of the shadow on the graph paper, where the pencil touched her nose. Kathy started giggling, and Chuck told her, “Hold still”. She started laughing, and he bent down and cupped her chin with one hand and held the pencil to her nose with the other. They were eye-to-eye about 10 inches apart, and she suddenly stopped laughing. I could see them fairly well through the paper. I was about the same distance from Kathy as Chuck. She and Chuck were staring into each other’s eyes, and the air was suddenly thick with tension. I finished writing down the coordinates and told Chuck to move the pencil to the bridge of her nose. Without a sound from either of them, he moved the pencil up. They kept staring. Kathy nervously licked her lips, and I thought I heard at least one of them breathing heavier. I was getting a hard-on, and when I glanced down to Kathy’s tits, I saw her nipples sticking out at least 3/4 of an inch. I got harder quicker. Bending over was getting uncomfortable, and my pants were tenting, so I told them I was going to get some chairs. Kathy sighed as Chuck let go of her chin and straightened up. He had a hard-on too, and it was very obvious and only 10 inches from Kathy’s face. She had to see it! Chuck immediately put his hands in his pockets and turned away from her as I headed into the kitchen to get the chairs. Neither of them had said a word.

Chuck didn’t come to help as I struggled through the doorway with the two chairs. Must have been too distracted? Kathy was still silent. I put one chair in front of her for Chuck to sit in and mine to her right. Chuck immediately sat down, and because he was so close, he spread his knees outside of Kathy’s. He cupped her chin with his right hand again and brought the pencil up to the bridge of her nose again. I was trying to concentrate on getting the coordinate measurements. It wasn’t easy with the distractions a few inches on the other side of the Mylar. Kathy was smiling at Chuck now, and he was closer to her face now. She was arching her back more toward Chuck, and I swear her nipples were trying to punch holes through her clothes. Chuck was so close now that he had to swing the pencil to the side to keep it from poking him in the eye. Then he kissed her lightly on the lips. Kathy sighed. I sighed. Chuck groaned. Kathy kept her head back against the rest and her hands straight down, clutching the chair seat. Kathy leaned forward for another, and this time I could see tongues were working feverishly. Soft moans were coming from Kathy, and Chuck was growling gently. I was drawn to Kathy’s near breast. It was straining against her T-shirt as she leaned forward into the kiss. My hand was drawn to it irresistibly. I cupped the lower curve of it and gently pinched the nipple between my thumb and forefinger. It was heavy and warm, and her bra was slick under the shirt. I was mindless. Kathy brought her hand up, and I was surprised when she cupped her hand over mine and pressed it firmly against her tit. I was rubbing her nipple under my thumb, and she was moaning into Chuck’s mouth as the kiss continued. Her nipple was getting harder, and my mind was buzzing. It was probably caused by oxygen deprivation since I don’t think I had taken a breath since the first kiss! The damn Mylar was in the way, and my knee was hitting the frame.

I had to stop my first and best boob grope to move the frame back. My hand was shaking as I brought it back to that wonderful tit, and I had to push my fingers under Kathy’s as she hadn’t moved her hand when I pulled mine out. I could see them without obstruction now, and Chuck still held her chin in his right hand, and his left hand was on his knee, still holding the pencil. They were really into the kissing now! Kathy was squeezing my hand as I rubbed her nipple with my thumb. I placed my left on her back and started rubbing it in slow circles over her bra clasp. I was wishing the bra would magically disappear. It didn’t, so in my mindless quest, I started pulling her shirt T-shirt out of her jeans. It didn’t come easy, but it came out. After I had the back of the shirt out, I started pulling at the sides and managed to get it all of the way out. They were still kissing, and she seemed oblivious to what I was doing, except she kept squeezing my hand on her breast. I slid my left hand up her back under the shirt, and it was magic skin. Her skin was unbelievably soft, smooth, and very hot! My fingertips tingled, and the tingle went straight to my cock. My breath was labored, and I was sweating now. My left hand reached the bra clasp, and I fumbled with it, and it came undone. What an accomplishment! I had performed a left-handed bra clasp manipulation. That was a skill I would be proud of for the rest of my life!

Kathy moaned again as I felt the bra cup loosen with my right hand, and my left went up her back to the collar of her shirt. I pulled my right hand from her grasp and quickly brought it to her tummy and started sliding it up under the front of the shirt. God! Her tummy skin was even hotter than her back! A couple of inches, and I pushed the bra cup up over her breast, and I had a full, warm breast in my hand and the nipple between thumb and forefinger again. Another groan from Kathy, and her hand was over mine again. Chuck must have dropped the pencil because his hand touched my forearm and began to feel around. He was trying to figure out what was going on by feel. I watched his eyes open wide in surprise, but he didn’t stop the kiss! He let go of her chin with his right hand, and I could feel it come up under the shirt to her left breast. There was another moan from Kathy. Chuck’s left hand dropped from my forearm, and Kathy’s hand over mine then went straight to her crotch. He started rubbing her through the jeans, and she moaned again. Chuck’s eyes were closed again until Kathy reached to his crotch with her left hand and felt his cock through his pants. His eyes pooped open again when she touched it. I could see her feel the length of it, then she clasped her hand over the tent in his khakis and squeezed. Chuck groaned, and Kathy moaned. I stopped breathing again.

Kathy must have been trying to spread her knees apart because Chuck spread his and hers followed. Now Chuck could get his left further down into her crotch and he was rubbing hard against the zipper and lower seam in her crotch. Kathy was breathing harder now and wiggling her butt on the chair. Man, this was going fast! I could almost see her whole tit as I squeezed it. I wanted more. I tried to pull her T-shirt over her head with my left hand, but there was too much going on. I got the back of it to the top of her head and there it stopped. She groaned deeply and sat up, breaking the kiss. I didn’t let go of my tit. She grasped the bottom of the shirt with crossed hands and pulled it and bra over her head. I don’t think she opened her eyes. She peeled the clothes off of her arms and threw them behind her. God, was she beautiful! My gorgeous sister was naked from the waist up! Chuck’s eyes were on her tits as she leaned back into the kiss. I was stroking her back with my hand and I moved it over her ass. There was more groaning from Kathy. She was really squirming around on the chair now.

Her tits were centerfold caliber. They were milky white with long pink eraser-sized nipples that protruded from puffy pink aureoles. The nipples were hot and hard, and the aureole was very soft with the firm breast supporting it. I had to kiss it. I leaned forward against her arm and brought my lips to the side of her breast. A long, soft kiss to it, and I was overwhelmed with the softness and her smell. I opened my hand and moved my kiss to her nipple. My tongue stroked it lightly, and her hand suddenly pulled my face to her breast. She moaned loudly. Chuck must have figured out what was up because his head bumped mine as he swooped to her left breast. I had the whole nipple in my mouth now, and my lips squeezed it, and my tongue licked it all over. Kathy’s head was pressing down on mine, and I felt her kiss my ear. Her tongue came into my ear and moved around it slowly. It was the sexiest thing that had happened so far. She pressed her lips harder to my ear, and her moans were almost deafening me, and her breathing on my neck gave me chills down to the tip of my cock...

Chuck was moving again, but I kept on with my tit kissing and licking. I heard his chair scraping the floor, and Kathy raised up from my ear. Suddenly, the waistband of her jeans was loose, and I could feel her panties with my hand stroking her back. Kathy was still holding my head to her breast as she slowly leaned back in the chair and arched her back. I felt the jeans slip down over her hips. Chuck was pulling them off, and she was helping! I slipped my left hand under the waistband of her panties and helped pull them off too. As my hand moved over her butt, my fingertips touched her warm and very wet pussy. Her butt was completely off the chair, and I slipped my middle finger into the hot, wet furrow of her pussy. My fingertip immediately slipped inside her to the first knuckle. Jeez, I was finger-fucking her! She was still holding her butt off the chair as I pulled the finger out a little and slid it up the slick lips until I encountered a hard little button. Kathy sucked in a big breath of air when I touched it, and she jerked her ass down, trapping my hand under her. That was all right. I could still move my middle finger gently over what must certainly be her clitoris. She was moving her ass in a circular motion on my hand and making jerky little clutches to my head at her breast. I couldn’t feel Chuck or see him at her other tit, so I kept on going. Kathy was mumbling in my ear and leaning back in the chair. My cock felt like it was going to split the skin! I had never been this excited!

Suddenly, I felt something push on the back of the finger rubbing Kathy’s clitoris. I turned my head to look down Kathy’s tummy, and there below her thin strip of light brown pubic hair was a cock! Chuck was going to fuck her! My protective instincts took over. I released her nipple from my lips and said in a panicked tone, “Use a rubber!” Chuck just said grimly, “I gotta do it!” I pulled my hand from under her butt and reached for my wallet.

“I’ve got one”, I almost yelled! Kathy let me raise up from her, and I let go of her tit with my right. I struggled for what seemed many minutes, but was probably a few seconds, to get my wallet out of my back pocket. I was staring at Chuck kneeling between Kathy’s widespread knees. He was grasping his cock with his left and rubbing it up and down between her cunt lips. Kathy moaned every time it moved over her clitoris and jerked her pussy up for another pass. As her pussy moved up, I could see the head of his cock go deeper between the pussy lips. He was going to get it in her any second! I frantically opened the bill pocket of my wallet and took out the well-worn foil packet. I thrust it in front of Chuck’s nose and yelled, “Put it on!” He focused his eyes on it, released the hold on his cock, and took it from me. He leaned back on his heels, and then I noticed he was completely naked, and so was Kathy. He feverishly ripped the packet open as Kathy moaned and stroked her hands over her thighs, tummy, and those beautiful tits. She was wiggling her ass on the chair and obviously trying to get her pussy closer to Chuck’s cock. He placed the condom over the head of his cock and rolled it down like he had done it a thousand times before. I knew he was a virgin. Had he practiced putting condoms on? He leaned forward again and started rubbing it up and down her slot again.

Kathy hissed, “Put it in!” It went lower between the lips, and suddenly he was in her about an inch. Kathy inhaled loudly and groaned. Her head was thrown back, and her tits were sweaty and slick-looking. I couldn’t breathe again. Chuck pulled back a fraction of an inch and pushed it in a little deeper. Kathy groaned again, and my protective instincts took over again.

“Don’t hurt her,” I whispered with a threatening tone.

“Go slow,” I warned him. His eyes focused on me, and he nodded. I looked at Kathy and asked her, “Are you OK”? She looked at me and said, “It’s good”.

“Tell him what you want,” I told her firmly. She turned her gaze to Chuck and said, “Out a little and back in.” Chuck responded by pulling back until the head was almost all of the way out and pushed it back in, just a bit further than before. He shivered as it slid back in, and Kathy grasped my forearm as she threw her head back and moaned again.

“Just like that again,” she whispered. Chuck was in control of himself now and slowly pulled almost all of the way out and back in, real slowly this time. Kathy’s knees jerked wider and then closed to squeeze his hips and hold him in. She reached forward and grasped his biceps to make sure he didn’t move. She must have held him like that for a full minute! Chuck’s head was shaking from side to side slowly, and sweat was dripping off his nose.
