Martin Shore was awkward pimply faced boy of 13 who lived with his parents and sister in luxury apartment on the upper west side of Manhattan. His mother was a firm believer in strict discipline while his father was more relaxed about raising children. Martin's father never physically punished him, that was always his mothers chore. Martin resented his mother's dominance of both himself and his father. Martin's mother ruled the house with an iron fist and often verbally pushed his father around. Martin took solace in the fact that his older sister got spanked as well, although it was only on the rarest of occasions. Martin received the biggest erotic thrill of his life when he "overheard" his sister's last spankings. He spent 3 days masturbating to the thought of his sister being paddle on her bare ass. Since it was getting close to the holidays, Martin's aunt Jesseca was in town for a visit. Jesseca was his mother's older sister. She was a buxom 35 year blond woman whom Martin had the biggest crush for. She was single and as his mother put it, the black sheep of the family. She loved to stay up late with Martin's father, drink brandy, smoke a cigar and talk all night with him about things that went beyond Martin's comprehension. Martin's mother, Emma only made snide comments about her behavior which Martin resented. One day during Jesseca's visit, Martin walked into her room without knocking. He wasn't trying to "steal" a cheap gawk, he just simply forgot his manners. He was greeted by the lovely sight of Jesseca bending over in mid- dress. She was wearing only a bra, panties and a pair of stocking which she was adjusting. The sight of her shapely bottom as it stretched the fabric of herpanties made Martin forget himself and gasp in pure disbelief. Jesseca turned around and let out an involuntary yelp at having been caught half naked. Martin gulped, muttered a quick apology and fled the room. But it was too late. Martin's mother heard her sister and rushed over to see what had caused her distress. She found Martin leaving her room and her sister inside, throwing on a robe. Jesseca only laughed. "He forgot to knock and, I guess you could say he caught me with my pants down." "He's supposed to knock, that's the house rule." "It's really no big deal, Emma." Emma stormed out of the room and return a moment later with Martin in tow. "Apologize to your aunt young man!" "I'm s-s-s-orry," Martin managed to stammer out. "You know the house rules Martin, take down your pants." "N-n-no!" "Martin don't make this worse for you than it already is." "Emma, this isn't re..." Martin's mother cut Jesseca off with a nasty glance. "He walked in on you, and you're going to watch him be punished." Emma grabbed a chair and hauled Martin over to her. He submitted and pulled down his pants. "And your underpants too!" "NO!" Martin screamed. "Not in front of Aunt Jesseca." His mother grabbed him, yanked him over her lap and pulled his under- pants down. She pulled out a large oval wooden backed hair brush from her pocket and proceeded to spank Martin until his bottom was dark red. He screamed and cried from the very beginning. Jesseca felt bad for Martin, and she resented Emma for her cruelty, but secretly she enjoyed the site of Martin's bare bottom being spanked. She knew he would be humiliated by the whole experience and while she watched Emma whale on her son's behind she received and idea which she thought he would benefit from. An idea she knew she could enjoy as well..... Martin spent the rest of the evening, sobbing into his pillow, while lying on his stomach. He was filled with anger towards his mother and towards Jesseca as well, since she witnessed his painful indignation. He comforted himself with fantasies of spanking both of them and slow drifted off to sleep. Several days later, Martin's parents went out for the evening to a cocktail party thrown by one of Martin's father's associates. Martin's sister was staying over a friends house and Jesseca volunteered to stay at home and "keep an eye on the boy," as Martin's mother had put it. Martin was in his room under the pretence of doing his homework. He was actually sitting on his bed masturbating to the vision of his Aunt lovely rear end, sticking up as it was as she bent over. He pictured it being spanked and this melted into his mother's bottom being spanking. As he ejaculated into a kleenex his bedroom door flew open and in walked Jesseca. "Hi Kiddo, I wa....whoops..." She left and shut the door. Martin nearly died. He quickly threw away the kleenex and zipped him- self up. He laid down on his bed in an absolute state of panic. His mother had walked in on him masturbating several months ago. She spanked him long and hard for that. Now his Aunt had seen him. It was embarrassing enough to be seen naked, but he was wacking off as well. He wanted to die. The was a knock at his door. "Come in," he said in a whisper. His Aunt cautiously opened the door and crept in. She pulled up a chair and sat down next to Martin's bed. Martin's heart began to pound in his chest in dreaded anticipation of what was to come. "I'm sorry Martin, I guess I forgot to knock." Martin stared at her in silence, and then he saw she had the hair brush, and his heart grew cold with terror. She held up the hair brush. "I guess you know what this for." Martin nodded slowly. She stood up, dropped the brush on the bed, pulled down her pants and underwear, turned around and kneeled on the chair, presenting her upturn bare bottom to Martin. "A house rule is a house rule, and I broke one." Martins heart stopped and his jaw dropped. He sat there frozen in disbelief. "What's the matter, Martin? Do you want me over your lap instead?" The wheels in Martin's head began to turn. The site of his Aunt's gorgeous bottom, upturned and on display (and bare no less!) drove him mad. He picked up the brush and approached her. "You're serious about this, Aunt Jesseca?" "Yes Martin. I've broken a house rule and now you must spank me. A good long spanking, Martin." And for incentive, she added, "like the one I saw your mother give you." Martin gripped the handle of the hair brush tightly and the corner's of his mouth turned down in determination, but something held him back. The thought of himself spanking an adult just didn't equate, and yet here she was placing her bottom on full display and asking him for a spanking! His first swat was light... "ow. Martin?" "Yes?" "I know I'll regret this, but you really need to put some effort into it, or it really won't be much of spanking." Martin smiled. That was his que. He cocked back his arm and with all his might brought the back of the hair brush down onto Jesseca lower right cheek... "YYYEEEEOOOOWWWW!!!!!!" Jesseca had the breath knocked out of her; not expecting the blow to be so hard. "That's a boy..." she started to gasp, but he cut her off. SMACK!! SMACK!! SMACK!! SWAT!! "Owwwww, Ohhhhh! Yeeeooow! Eeeeee!" Martin worked his arm in rapid fire quickly covering his Aunt's bottom with stinging blows that bit into her ass flesh and send waves of pain through her bottom. She gripped on the back of the chair, and gritted her teeth like she was in for the ride of her life. As the pain began to build and swell in her rear, waves of pleasure began pulsing through her crotch. The thought of her 13 year old nephew spanking her bare bottom drove her mad with erotic excitement. Martin was sporting an erection he thought would explode. He was determined to paddle his Aunt until his arm was sore. "That's it Martin..OW...I broke the...YEOW...house rules and...OWWW.. I need to given ...OW...good spanking..YEEOW!" Martin noticed how her cheeks were growing redder by the swat and soon the took on a deep hue of red, but he felt like he still had some more life left in his arm. He had done a thorough job covering he ass cheeks with spanks and stopped to admire his work and see what her reaction was. Jesseca let out a deep breath, "are you through?" Martin paused, and then decided to test his power. "No, I'm not." "Oh," Jesseca said, and offered her bottom up once again. Martin smiled and resumed paddling her with the hair brush. The pain had grown intolerable, and it was all she could do to keep from leaping up. Finally he stopped and said he was finished. Jesseca immediately leapt up and began to rub her tender behind, but she found it too sore to even touch. She frantically hopped around the room fanning her rear end and Martin thought she looked crazy, like someone trying to shoo away demons which were sticking her rear with little pitchforks. But the site of his Aunt's naked, beet red bottom also drove him wild. He wished she would leave so he could wack-off. Finally, after several minutes, Jesseca stopped dancing and Martin saw there were tears in her eyes. She came over to him and they hugged. "I promise never to come into your with out knocking again." Martin smiled and shrugged, "Sure, thanks. Are you okay?" She smiled and said yes. She shuffled out the door, her pants and panties around her knees. Her bottom hurt too much to pull them up. The site of her reddened naked ass jiggling as she shuffled out was etched in Martin's mind for years to come. Both parties spent the next several hours masturbating in their respective bedrooms.
