Fourth Encounter Some time later Billy awoke still on top of Mrs. Bowens, with his still rock hard cock still deep inside her. Mrs. Bowens whimpered as Billy pulled his cock out of her gently, took her by the hand and pulled her from the desk. Turning her around, Billy raised her blue pinstripe skirt and pushed it up over her ass cheeks until he laid her black ass bare so he could mount her from behind. "Yes, fuck me like a dog, Master! Fuck your Black dog!" Mrs. Bowens screamed as he pushed her forward down on the desk and spread her legs, easing his white cock deep inside her black pussy from behind. She braced herself with her arms as he reached under her and began gently squeezing her nipples, milking her breasts all over the desk. Mrs. Bowens reached all the way across the desk, curled her fingers under the desk top edge and began humping backwards, meeting his forwards thrusts faster and faster while grunting Billy's name in an almost bestial voice. "Fuck me Mr. Fuller, ahhhh! Fuckmefuckmefuckme, ohhhh, uh-huh!" Mrs. Bowens grunted as she thrust backwards against Billy. "Mama, you in here?" everyone froze when they heard a high voice outside the door break the heavy breathing in the room. "Oh shit, that's my daughter Shanita" Mrs. Bowens moaned as she began humping even faster back against Billy. "My husband will kill us both if she tells him I fucked a whitie. He was in the Black Panthers years ago!" Fear and need made Billy's dick remain hard and he thrust in and out of Mrs. Bowens even faster as he heard the door open and he glanced over at Shanita as she entered the room. Her jaw dropped as she saw him mounted with her mother and watched as his cock rammed in and out of her mother from behind. He grinned and kept fucking the older black woman doggie style as Shanita dropped her books in shock. Billy reached down and slapped Mrs. Bowens' left ass cheek gently but firmly as he continued thrusting in and out of her black cunt. Mrs. Bowens squealed each time he slapped her, alternating between each ass cheek. "Spank me, Master! Oh spank your nigger slave, uh, uh ah, ah, ah!" Mrs. Bowens shrieked each time Billy slapped her ass, making her firm black ass cheeks ripple and jiggle as he struck them. "What are you doing on my mama, you freak!" Shanita yelled as she rushed over to the desk. Tonia and Suwanda intercepted her and held her back as she pushed against them. Shanita watched her mother's face that was now covered with a slight sheen of sweat contort with pleasure as Mrs. Bowens grunted and moaned in pleasure while she thrust backwards against Billy. Shanita pushed against Tonia and Suwanda but they merely moved her behind Billy so they could all see the action better. Shanita looked down and saw Billy's white dick thrusting in and out of her own mother's black pussy. Her legs weakened and she fell to her knees but that only gave her a better view as she watched Billy's balls suddenly contract and his white dick pulse as he shoved it to the hilt inside her mother. Shanita saw pussy juice mixed with white semen as it ejected from sides and bottom of her mother's tight black pussy lips in a sudden flood. "I'm fucking your black mother pregnant, you nigger bitch! Ohhh, uhh, ahhhhh!" Billy grunted as he moved his hands to Mrs. Bowens' hips, grasping them tightly and thrust his white dick to the hilt inside her black pussy, holding it there while he filled her black belly full of his white semen again. Tonia moved around to the front of the desk so she could see Mrs. Bowens' face as Billy came inside her. She had already removed her clothing earlier and stood naked in front of Billy and Mrs. Bowens just inches away from Mrs. Bowens' head. As the pulsing from his cock began to subside; Billy reached forward and gently twined his fingers in Mrs. Bowens' shoulder length black hair and pulled her back towards him. She arched her back and moaned when Billy reached around and grasped her large left breast with his left hand. He began squeezing the nipple and suddenly Mrs. Bowens' breast began pulsing and shot milk all over Tonia's breasts and tight black stomach. Billy grinned as he moved the aim of Mrs. Bowens' breast milk higher and the milk shot all over Tonia's face and into her mouth as Tonia opened her mouth in anticipation of the flood of milk. Mrs. Bowens shrieked as her pussy clenched tightly down on Billy's cock; causing his white dick to shoot another powerful burst of his thick White cum deep up inside her Black pussy as they stood up nearly straight but with Billy still mounted fully inside her. Billy jerked against Mrs. Bowens while he squished her large breast tightly; thrusting his White cock all the way to the hilt inside her Black pussy. Billy pressed Mrs. Bowens against the desk and it moaned as it slid across the floor slightly while he filled her Black pussy full again of his life-giving White sperm. Her breast milk oozed from around her fingers as he squeezed her breast; some more of it shot across to Tonia's open mouth again. “Yes, cum in me, Master! Give your Nigger slave a white baby! Uhhhhhmmmm, yeah!” Mrs. Bowens screamed as she felt Billy’s cock burst inside her again. “Oh yeah, Missus Bowens! I’m breeding your Nigger pussy pregnant with my White cum!” Billy yelled as he ejaculated a final thick wad of his white semen deep inside Mrs. Bowens’ tight black cunt. Mrs. Bowens had not seen the effects of menopause yet and still had her monthly periods. Unfortunately for Mrs. Bowens this most recent blast of White semen held some particularly potent spermatozoa that rapidly raced its way to her womb, found an eager egg waiting for fertilization and coated the egg. Many sperm cells tried to penetrate the egg and two of them swiftly eased their way in; impregnating Mrs. Bowens with twin White babies. “Mama! What the fuck!” Shanita screamed when she saw Billy’s small white cock withdraw from her mother as a small flood of white semen pulsed out of her mother’s black pussy, flowed down her beautiful black legs into her high heeled shoes and down the front of the desk making a puddle on the floor. Shanita gasped when she saw Tonia and Suwanda both fall on the floor; lapping up the thick white cum with their tongues.
