please kingkoi do not f*** a cactus, we've all heard of the smooth wonders of it's surface but when i stuck my d*** against it i quickly found out how horrible it was..i was stuck pulling out spines for over five minutes, it felt so good against the smooth surface and every 15 minutes i have to remind myself not to go hump the cactus..so please whatever you do..don't f*** a cactus
