Discharge during and post fingering?

My boyfriend was fingering me and when he was done we see that his hand is covered in thick gooey discharge that’s this brown color. I’m not due for my period and it’s been about 2 weeks since my last one ended so it’s not post period discharge either this picture isn’t the best for texture but it’s good with color, is this normal for fingering?? And if so, what is it?
