When I was twelve years old I used to jerk off and mix my cum into pudding cups that I'd serve my friends, especially the girls. It just really turned me on knowing that my cum was the first they'd ever swallow. Then one afternoon, my mom interrupted us and went all "oh Tapioca, my favorite!" and grabbed one before I could say anything and ate it down in 3 big spoonfuls. A little had dribbled onto her bottom lip, she so wiped it up with a finger and then sucked the finger clean and sighed. "Delish!" I honestly don't think anything since has made me quite so hard.
