Homemade Self Nipple Torture

[StagnantSoul]

So my ex used to always torture my nipples, she'd do things like put clamps on them and pull me around, squeeze them with strings, tie weights to the string and step on the weight... And I miss it. I've been trying my best to torture my own nipples, and I think I've been rather successful. I've been tying large books tight to them and hanging them off, taking a small handheld fan to the nipples, swinging weights off them with strings. Can someone give me some more suggestions? I think the fan is the best so far, it leaves my nipples hard, hot, and sensitive for hours afterwards. Thanks for any help in advance!
