I (21F) pleasured my friend [FM]

So I’ve been seeing this friend of mine for a bit now, and we have a great friendship going on, sort of like FWBs. But the other day, things were getting a bit intimate between us while I was over at his house, and he started feeling me up while we were watching a movie. Then one thing led to another and he took off his pants, showing his cock in front of me, and before I could go down on him, he told me he’s always wanted to know what my spit smelled like, and told me that he wanted to receive a saliva facial from me. I was confused at first, but I assumed it was his kink so I went ahead and did it, and started licking his whole face from top to bottom until it was drenched in my spit. Then he said he wanted to let it dry so we waited, and I noticed afterwards that my saliva was really stinky and it got me a little embarrassed but also turned on he was smelling it. Then, I started going down on him and sucking his cock, using my tongue to pleasure his tip until his cock was drenched as well. The smell of my own spit drying on his cock was rancid, but I kept going and could hear him moaning “ohh your spit is so stinky Eve” and this honestly turned me on a lot. Eventually he came into my mouth and I went to go clean up, but he said he’d rather keep my smell on him, so we finished up watching the movie while the smell of my stinky spit was in the air.
