I have a line in mind.. A girl, most likely a teenager or in her early 20's, hasn't yet lost her virginity but has a boyfriend who's been patient with her thus far. Needless to say, she experiments with her dog.
Leaving things there to keep it open for planning/ideas/sharing. A PB or an OC is fine. Your choice. I would like to write the dog.
If you're interested, I'll link you to a journal for PM'ing purposes.
