well I guess you can call it subtle...
when your mom called me over to smash. I was down with it, but then she mentioned she had her sister over for a visit. so I can in through the window into her room where she was waiting for me. she said we had to be subtle about it so we wouldn't alert her sister. I said alright, and after 10 mins of straight stroking and thrusting, I finally finished. even with her dog sleeping in the corner across from us, we didnt even wake him up
so I guess you could call it subtle
