ISO: Bi-Threesome Story I Read On Literotica

I am looking for a story I read not too long ago on Literotica. It was about a girlfriend who wanted to see her boyfriend suck cock. They watch porn together and she pulls up a video of a bi-threesome, and they talk about it and agree to try it. Then later on when the boyfriend has his friend over playing video games the girl starts to send nude pictures and the boyfriend shows his friend and they keep that up until they are both masturbating. Im pretty sure it ends in a threesome.

Does anyone know of a story like that? Or anything similar?
