sniff them

Bringing the panties up to your nose you inhale deeply of Nikki's feminine scent, you knew it was wrong and that she was your Aunt but it didn't matter in that moment as you revelled in the sensations. Your lips kissing the crusty stains until your tongue tentatively flicks out and tastes the sweet mess.

Your dick grows erect as you kiss and lick at the panties until you're on the verge, deciding against cumming in case you make a mess and putting the panties down where you found them before stepping into the shower.
