Update here...
Saw her yesterday, again. Somebody asked about titfucking. Actually the second or third time I saw her, while she was leaning over stroking me off, she suddenly said softly "ready?" and then just leaned over, squeezing her tits over the tip of my dick rapidly. I came in record time. We now do this every time, and she's allowed me a bit more access, like smacking my wood on her boobs and nips. She doesn't seem to mind her tits being played with roughly, and seems to like pulling and pinching on her nipples.
She weirdly never takes off her mask so it def seems like she's trying to remain a bit anonymous while doing this. She will give me a flash of her face if I ask, but then very quickly put it back on.
It seems like she'd be willing to take things even further but I think I'm going to draw the line here as I'm not interested in a relationship or making things any more awkward. I'm afraid it would go that way if things elevated to me servicing her in any way. She already mentioned a few times having me over and cooking me dinner, and I don't want things to go in that direction.
As for pics, I asked her for boobs only or boobs with face covered, and she said no. But then later she said she might send me a "surprise" text with them sometime. So, fingers crossed!
I'm not sure there will be much more to this story unless I end up with pics, but thanks all for following along.
