Wood Vibrator
I'm not sure if it was appropriate for the roommate of my boyfriend to give me a vibrator, but my boyfriend didn't seem to mind. The boyfriend and I have been over for decades, but the vibrator is still useful.
The roommate had taken up whittling, and he practiced using odd pieces of wood scraps from a lumber yard. He created what was basically a wooden penis for me as well as one for the girlfriend of his other roommate. Maybe it was his way of having a relationship with his roommates'' girlfriends, and I'm sure there's a lot of psychology behind it. Mine was very long, though it wasn't terribly thick, and it was varnished smooth. I have used it on a number of occasions, always with a condom because I'm not sure how good wood varnish is for my pussy. I enjoy sliding it in, how unyeilding it is, and how my cunt contracts around it when I cum. Just thinking about it has me wet.
Just use a hairbrush
You has his friend's roommate should use them together
