I was 12 years old...
For two or three days I couldn't ride my bike and had to pedal standing up. My butt was really blistered from my mom's belt.

This reminded me of having to ride my bike to-and-from school when I was a boy. It was not really optional because I lived too far away from the school for walking to make sense, but not far enough to ride the school bus.
School spankings/paddlings were usually administered during 1-hour after-school detention periods or during 4-hour Saturday morning detention periods. I attended very strict Christian schools (grade school, junior high school, & high school).
In the primary and elementary grades (grades 1-6), these detentions were served in the classrooms, where bare-bottomed over-the-lap punishments were administered by the teachers with hairbrush-shaped paddles (without any bristles). In these grades, naughty boys and girls were punished in front of each other. The boys had to pull down their school uniform pants before laying over the teacher's lap. When in position, the teacher would pull the boys' underpants down just far enough to bare their butts for the other boys and girls to witness their buttocks being paddled to a rosy/scarlet/crimson shade of red. The only difference for the girls was that they wore school uniform skirts, so they went over the teacher's lap first, and then the teacher lifted their skirts and lowered their panties.
In the junior high school and high school grades (grades 7-12), the after-school detentions were served in the gymnasium, where the PE coaches were the disciplinarians and required the naughty boys and girls to run laps and do push-ups, sit-ups, and pull-ups for one hour. And then, in the boys' and girls' locker rooms (while still completely wet and naked after showering), the naughty students would have to straddle and bend themselves over old decommissioned vaulting horses for the coaches to administer the leather strap and/or the school paddle in front of the other naughty students of the same gender. In the boys' locker room, it was not uncommon for embarrassment and frightened anticipation to cause erections, especially for 7th grade boys experiencing this disciplinary ritual for the first time. And, some boys like me never outgrew these erections. My last such punishment was in the 12th grade (senior year in high school), when I was 17 years old, and I was rock hard before, during, and after my trip over the vaulting horse.
I hated riding my bike home after receiving school discipline! During my junior high and high school years, this was especially difficult, having just finished an exhausting one-hour disciplinary physical workout. I was unable to ride all the way home standing on the pedals, so I would try to sit very gingerly on the bicycle seat, but eventually I would ride over a bump which was quite uncomfortable with already very sore buttocks!
One time, in the 9th grade (freshman year in high school), I was overheard telling a friend that that my female algebra teacher was a F_CK'ING B_TCH. My friend was overheard agreeing with me by rephrasing what I had said, but using the C word instead of the B word. So, my friend and I were assigned half-day (4-hour) Saturday morning detentions. My dad tanned my hide with his razor strop at about 6am, right before I had to ride my bike to the school. At the school, after 3 hours of doing campus landscaping/painting work and running laps (with an already sore ass), my friend and I showered and then straddled our wet bodies over the vaulting horse to receive 10 swats with the paddle. Then, I had to ride home on my bike, with my ass on fire. When I arrived at home, my dad had me fetch and peel a 4 foot river willow switch which he used to put a dozen very painful red stripes/welts across my bare ass, while biting down on a bar of Ivory soap to "clean out my filthy mouth". On Monday morning, I was still unable to comfortably ride my bike to school, and the boys in my PE class teased me when they saw my still-tanned and striped/welted buttocks in the locker room showers. I never used foul language on campus again!
