This thing was at least 10 inches long, and 7 inches in circumference. Mom was still holding me in place, as Dana walked up behind me. Some girls use two-ways, so they are fucking themselves at the same time they are fucking somebody else, they get the physical pleasure. This wasn't that. It was a strap-on. She didn't get a physical sensation from it, it was all about the domination. It's not like I had never stuck anything up my own ass. I had experimented. But never with anything nearly so big. I still had mom's panties in my mouth, so anything I tried to say was muffled. I was shaking my head and trying to say, "Not that. It's too big!" Dana squeezed my bruised butt cheeks hard and smacked them hard. She said, "You're going to take it, wench. You're going to take it all." She picked up a jar of Vaseline and smeared some all over the dildo, putting it a bit thick on the head. Then she got some more Vaseline on her fingers and started sliding them up my ass. She thoroughly coated my anal canal with the Vaseline, but didn't stop with that. What started out as lubing me up turned into an extensive finger-fucking. After a few minutes of this, my dick was limp but I was still precumming like crazy. My nervousness at the prospect of that huge dildo gradually melted away. Still being held by my mom over her knee, I relaxed and enjoyed it. I let out a groan and arched my back a little, trying to push my ass up in the air. I couldn't get enough! Dana kept on finger-fucking me. She snickered and said, "You're such a filthy whore." As she fucked my ass with the fingers from one hand, she repeatedly smacked it hard with the other. Then she squeezed my cheeks hard and spread them. The initial dildo insertion was slow. My ass wasn't ready for something that big. She just put the head of it in at first. She was gentle at first. She took her time, fucking me with just the head. She proceeded to slowly push more and more of it in. As she fucked me, she also swung her hips right to left, even throwing in a swirling motion here and there. Gradually getting more and more of the dildo up inside me. The dildo stimulated my prostate, and I loved it. I know I was moaning in pleasure. Eventually, she got it more than half way in. She smacked my ass some more, saying, "You're going to take it all, bitch." She kept on fucking me slow, pushing more and more of it in. When she finally pushed it all the way in, up to the base, it hurt like hell But was also a major turn-on. I was trying to squirm away, to no avail. She began fucking me harder. Dana gradually increased in speed, fucking me faster and faster. She fucked me hard. She fucked me rough. She fucked me deep with the full length of the dildo. Somebody handed Dana one of the ping-pong paddles. She paddled me as hard as she could while she continued to fuck me hard, fast, and rough. She scolded, "Stop squirming, bitch! You lay there and take it! I'm going to wear that ass out!" Dana alternated cheeks with the paddle, spanking and fucking me. I tried not to make a sound, I didn't want them to know how much I was loving this. My mom keeping me pinned over her knee while my cousin fucked the hell out of me. I was in heaven! Dana beat my ass hard while she fucked it even harder. She was like the Energizer Bunny of sodomy. She just kept on going and going. I was screaming like a girl having an orgasm. Dana kept on spanking and fucking me. She said, "You gonna' scream like a bitch? You like it, don't you, tramp. You love that big dick in your ass. You're just a filthy whore, aren't you? Aren't you?" Mom pulled the panties out of my mouth. She said, "Answer her." I was screaming in ecstasy. "YYYEEEEESS!" Dana fucked me harder. "Say it! Say you're just a filthy whore!" "IIIIII'M JJJUUUUSSSSSTTT AAAAAA FFFFFFFIIIIIIIILLLLLLLLTHYYYYYYYYY LLLLLIIIIITTLLLLLLE WWWWWHHHHHOOOOOORRRRRRREEEEEE!" She paddled and fucked me for quite a while longer. She kept on talking dirty, calling me every degrading name there is. After she stopped, mom slid me off her knee onto the floor. Grandma said, "Look at him. Look at what a sick pervert my grandson is." To my mom, "I blame you for this. Go cut me a switch." My mom obeyed her mom. She picked up a pocket knife and walked out into the yard. There were many trees around the pool, and she cut a fresh green switch from one of them. She brought it inside and handed it to grandma. Grandma gave it a few test swings in the air. She said, "Yeah, this'll do." To my mom, "You know what to do." As mom bent over the back of the couch, grandma trimmed the twigs off the switch and made it smooth. Grandma stood on mom's left side and swung the switch with all of her considerable might, solidly impacting mom's ample backside. Mom let out a loud yelp and jumped, but stayed bent over. Grandma said, "Stay in position, young lady" and hit her again. Mom cried out but stayed in position. Grandma didn't even raise her voice. She calmly said, "You are a bad mother" and hit mom again. Mom cried and wailed, but barely flinched. Grandma said, "This is how you discipline a naughty child" and hit her again. She switched my mom slowly and deliberately, maximizing the impact of each strike. Mom was howling at the top of her lungs, staying bent over the back of the couch, taking it. Grandma hit her again. And again. And again. After 7 licks of the switch, she went to mom's right side. She kept on switching my mom as hard as she could. A total of 14 times. She said, "That's one for every year you've been a bad mother to him." Mom stood up and slowly walked to another part of the room. Her pussy was so wet she left a big wet spot on the couch. Her nipples were hard enough to cut glass, pressing out against that thin bikini top. I could see linear bruises the switch had left on her backside through the bikini bottom. Her face was beet red, and had a steady stream of tears coming from each bloodshot eye. Snot ran down from her nose right into her open mouth. She was crying so hard she didn't even care about that. Grandma looked at me and said, "Now it's your turn. Go cut another switch." I started back toward the closet. She grabbed me by my ear. "Where do you think you're going?" "If I have to go outside and cut a switch, I better put my trunks back on. They're in the closet." "No. Don't put your trunks on. You need the humiliation of being nude." "Wait, what? Outside? The neighbors might see me!" There were enough trees that there was a good chance their view would be blocked. There was just as good of a chance that I would be seen. Completely nude. Considerable bruises on my wrists and ankles from the zip strips' being so tight and from my struggling against them. They were nothing compared to the bruises on my ass and balls. Grandma put the knife in my hand. She said, "NOW, young man!" I was in no hurry to get out the door. I took a couple seconds inside the doorway to look for a good place to cut. Once outside, I rushed as fast as I could. It wasn't fast enough. Stacey, the girl next door, had some friends over. They were all outside, and saw me. They made sure to let me know they saw me. There were catcalls, "weet-whew" whistles, comments on my body and penis size, and of course comments on my bruises. Stacey even said, "Can I spank you next?" I just shook my head and hurried back in the house. Grandma looked at the switch I had selected. Her tone was a bit angry as she said, "It's too short, and a bit crooked and wimpy. Go ahead and bend over the couch. Consider this a warm-up, you will be cutting a better switch after I spank you with this one." My cousin Becky spoke up. Even though she was from my dad's side, she still called my mom's mom "grandma." Everybody called her either "grandma" or "mom." Becky said, "Can I do it, grandma? I'm the only one who hasn't had a chance to hit him." Grandma said, "Yes, that will be just fine." She trimmed the twigs off the switch and made it smooth. Then she handed it to Becky. Becky gave it a few test swings, saying, "This is short enough to use over my knee." She sat in a chair and patted her knee. I just stood before her, knowing what she wanted, but hesitant to do it. This made her angry. She said, "Get over my knee, boy. Now." I started to back away. She reached out and got hold of my wrist. I pulled against her with all my might. She sat the switch down and pulled on me. It took her just a few seconds to wrestle me onto her knee. She pinned my legs down with her leg, and pinned my wrist into my back. I was still fighting her, to no avail. Becky picked up the switch, and brought it down hard on my backside. I screamed and squirmed on her knee. She kept on switching me hard. My dick got hard again, rubbing against her bare thigh. I kept on fighting her, howling and wailing in pain. It was such exquisite torture, being beaten over my cousin's knee like this. She brought the switch down just as hard on my ass again. And again. And again. She flogged me mercilessly for a few minutes. By the time she let me loose, I was bawling uncontrollably at the top of my lungs. A stream of precum went from my throbbing dick to her bare thigh. Grandma said, "You did as good of a job as anyone could, with that pathetic switch." Handing the knife to me, she said, "Ok, young man. This time do it right." I stood in the doorway for just a second, and spotted a limb I knew would please her. I rushed out to get it. Stacey and her friends were still outside, and watched me again. Stacey gave me a backhanded complement, that my dick was a bit on the small side but looked great sticking out of me like that, she would love to give me a good whipping and then ride me hard. I brought the switch back to grandma, who was clearly quite pleased.
