commented on SL Letter of the Day: Rocky Mountain Rainbows
This is an easy one and I sort of concur with the previous comment. At least the vomit part.
A Rocky Mountain Rainbow is the act of forcing your partner to give you oral sex to the point of him/her vomiting, preferably on the dom's genitalia.
Usability?: "I'm gonna give my man a Rocky Mountain Rainbow this weekend after the game."
Or: "I wanna see/feel that Rocky Mountain Rainbow before I come on your face."
Rocky Mountain Rainbow sounds soooo much better than "forcing your partner to puke while giving head."
