We had already gone to bed, my wife started talking about bad memories from childhood and eventually started tearing up, I started caressing her cheek (mostly dry), eventually reaching the tear streak that was marking the middle of her cheek, I gently traced her tear streak from below her eye all the way, almost to her chin, where I catched her tear. She wasn't producing many tears, it was a slow flow, and it started with a small streak, and it developed to a small teardrop running down the same streak, then a new streak that ran down the inner corner of her eye, along the nose, eventually becoming a larger (not big, but larger than the previous) tear, I don't remember seeing a tear run down her cheek from the angle I was, it was like I was seeing her cheek as a street (plain from my pov, and the tear was kind of like a tall round drop as it slowly went from her eye to the middle of her cheek, I rubbed my cheek against hers every now and then, feeling her tears on my face, I wiped others, and I kissed a few more as well as kissed her tear streak when the wetness renewed with a new tear.
Eventually the conversation touched me as well, and I shed a few tears, fast flowing tears in a single stream down each of my cheeks, I think there were four or five tears, then stopped, then another wave of tears fell down my cheeks, maybe three or four more, my wife passed me a tissue to wipe my nose and my tears and she took one for herself.
I hadn't had the opportunity to kiss her tears in a long time, so I really appreciated this obs.
