All Chapters of DOCTOR SIN ANATOMY(erotica series): Chapter 1 - Chapter 10

The next day, Brenda arrived in the library an hour earlier. Justin came just in time. He looked dashing in his light green shirt and beige coat and tie.He’s such a nerd and a stuck-up, Brenda grinned impishly. Wait till I get my hands on his phallus. She smiled, elated to have a challenge on her doorstep. She loved challenges!“Let’s start about the various specific properties of these substances,” Justin used a pad paper to write on.They were seated, side by side, on the small table; their bodies close and their knees and shoulders almost touching. From afar, they were like lovers planning for their wedding. Brenda can smell the clean, tangy odor of his cologne, and it made her want to lean closer to him. Justin sensed this and he tried to move farther, but . . .“Is the double bond found in this carbon atom?” Brenda pointed to the diagram on the table.He had to move back closer to see what she was pointing at. As she pointed, her cleavage appeared. She did it on purpose to sedu

he had never tasted. Brenda sucked him then, gradually going deeper and more desperately, as she took in the juicy flesh until she felt him in her throat. Then her mouth moved up and down his shaft, suckling his cock leisurely. The car came to a stop once more and Justin closed his eyes to savor the delightful sensations coming from Brenda’s ministrations. His dick was enormous -around 10 feet - that Brenda nearly choked when Justin raised his hips to meet her mouth. It was just so huge; she could not take it all in. Instead, she used both of her hands and mouth to accommodate his organ. She gripped the base of his thick dick and massaged it with her fingers in a twisting motion as her mouth and tongue sucked and licked its upper portion – not an inch of his cock was left unoccupied. Over and over her tongue and fingers went up and down - gently, tenderly, incessantly. From what she had heard from friends, the penis was as sensitive as the clit of a woman, so her tongue and her mouth

While his penis was busy fucking her, his mouth was also on a quest to conquer Brenda’s lips and tits. Their sitting position made it easier for him to suck her tits when she came down grounding her pussy into his upright cock. Now and then he would suck her mouth as they pause before another penetration. The tempo was building up and their groans of pleasure echoed inside the room. Their bodies were drenched with sweat in spite of the cool temperature, and their love essences - including a small amount of blood - mixed with one another. Up and down Brenda rode his bucking stallion, grinding her pussy into his dick, the pain totally forgotten now. She clung to his neck and rode him wildly, stooping to kiss him on the mouth every now and then. Justin groaned, “Shit . . . keep going . . . move with me . . . aaaaah,” he plunged deeper and wilder. They moved in unison, slamming their pubis together, uttering words that only they can understand. “Oh God, aaaah, f...u...c...k meeee!” sh

Meanwhile, John was masturbating and kissing Brenda whenever Justin left her mouth free. He was also massaging his dick relentlessly until it grew as big as Justin's. He pinched Brenda's tits at will and placed his hand between their colliding bodies, once in a while. Then Justin grunted violently and then ejaculated, his body jerking like a puppet on a string that had gone haywire. Brenda climaxed almost at the same time, and her body shook with him in a state of jubilant release. Not to be outdone, John strained for his climax and joined them in a wonderful chorus of sounds that conveyed their sexual satisfaction. "From this primary position, you can easily shift to other positions such as, the scissors, the bridge and the helicopter," Justin stated huskily, his cock still tumescent and awake. John interjected, "remember the missionary position because it's utterly satisfying. Eventually, you'll learn all the other positions." Graduation day was fast approaching and Brenda was

Colton captured Jena's breasts with his hands and nibbled the nipples, one after the other, through her thin blouse. Then he quickly kicked off his pants and undies and straddled Jena. He started pumping his enormous dick inside Jena's vagina that she had no time to get ready. Jena felt the smoldering flame inside her pussy come to a standstill. She felt a stinging pain in her narrow slit and she couldn't help but cry out in pain. He stopped and breathlessly uttered: "Shall I stop now?" "No. but please go slow," she whispered. Colton obeyed her, slowing down his rhythm - but it was only for a while. When Colton felt the sweet sensation of her tight pussy clinging to his dick, he raged on like a crazy bull, humping the life out of her. It was his first time to make love and it burned his groin. The feelings gradually expanded to the entire part of his body until his body was enflamed and he ejaculated with one last grunt. "Oh, fuck, fuck, I'm cumming," he writhed spasmodically as th
