At WorkI've been sitting here at work with several of my shirt buttons undone with one of my hands inside just rubbing and tweaking my nipples. Luckily I don't share an office, when I used to, I used to do my nipple rubbing when I was in the loo, in fact sometimes I'd have one hand on my nipples and the other down my pants while sitting on the toilet. Not using the toilet just enjoying the privacy of the cubicle.
Not that I'm adverse to a sneaky nipple play in public if I think I can get away with it, it's just sometimes difficult to explain why you've got your shirt unbuttoned.
I've been rubbing my nipples since I was a small child but recently I have got to the stage where if I rub enough I can get an org*sm and sometimes I can even get milk to come out, in which case I then try to suck the milk from my nipples. Not always easy as my breasts are quite small and I can only just get part of my nipple up to my mouth but if I squeeze real hard I can usually get some milk into my mouth and boy does that feel good.
I'm actually starting to feel horny just writing this down.
I may have small breasts but the amount of enjoyment I can get from them has nothing to do with their size.
