How hard are you when you're licking a woman's pussy?

Hard and leaking!

Most times semi-hard. I'm focussed on her - her smell, her breathing, her trembling, her taste. her moans. I know after she cums she will go down on me and I'll get very hard .... then we will fuck.

Very

Depends, if she did me first probably not, but eating pussy is the quickest way to recovery for round two.

I almost always dine before getting sucked so I'm always rock hard. Even though my complete focus is on her pleasure the act itself keeps me erect.

Very hard if it’s dripping with another’s man’s seed

I'm usually laying on it and I'll grind the mattress while my tongue flicks her clit.

I’m usually hard to start then lose it as I concentrate on her, but when she cums, I get hard again right away. Giving someone an orgasm is my biggest turn on.

Fully hard. Oozing precum too most likely.
