- Jerk Off Instruction and Small Penis Humiliation by MistressRavenFD Let me show you something, you worthless pin-dick This is my sewing thimble. I’m not exaggerating when I say your shriveled little nub couldn’t even fit inside this pink sewing tool. Look at this dainty little thimble, barely bigger than my fingernail. It;s still more substantial than your worthless worm. At least the thimble has purpose. I want you to jerk your tiny dick and show Me how full you can make it with your cum while I giggle. My bet is that it will be bone dry at the end. #sph #smallpenishumiliation #cumcountdown #joi #jerkoffinstruction #humiliation #femdompov #mistressravenfd
