I haven't smoked in years, but when I did, it would usually be at night, before bed. Smoking generally makes me hornier than usual, so I'd end up masturbating with vivid fantasies before falling asleep.
Not legal here, and in my 25+ years as a cop I wouldn't have dreamed of it but it was a regular thing in my youth.
A few shots from a bong enhanced my masturbation, my many fantasies and fetishes, and sex with both females and (my only) male partner.
It plays a big role in my stories.
Both of my kids live in Oregon, and the wife and I have talked about maybe getting some of "the kind" while on our next visit in the motor home. I'm almost 60 and she's almost 65 so we hardly have a drink anymore since it's contraindicated with many of our medications. No such side effects with pot so maybe we can have a smoke...and..."If this RV's rockin' don't be knockin"...."
