At my 30th birthday party at a local bowling alley, my husband and several of our friends decided a birthday spanking was in order. I attempted to resist but it was fruitless. Initially I was spanked through my jeans, but when they realized that it was not hurting my jeans were unbuttoned and yanked down causing my panties to go down with them as well. As they cracked my ass to the point of stinging I was kicking my legs and begging for them to stop. They coerced me into bowling nude in exchange for stopping spanking me. This was taken when we got home.
