When siamese ponies masturbate, is it masturbation? or incest?

>the 1.5 of you are taking a shower before bed
>As you do every night
>You mindlessly let the water run down your mane
>Just another night alone-
*lick*
>"W-what are you doing?"
"What... it's been a while since we've had any stallions over... don't tell me you aren't getting a little... pent up."
>"N-no, not at all"
>She was right, but that's not unusual
>In fact, you usually only score one stallion a year
"Don't lie, I can feel you are..."
>You can feel your sister slide your thighs together
>the shower is only half the reason you're wet down there
>"S-sister, please, i-if you want to do... that... just do it"
"Yeah, but wouldn't it be more fun if we... did it together?"
>You cant believe what you are hearing
>That's disgusting!
>You and your sister?
>You could never-
>Lips
>You bring yourself out of your inner conflict and see your sister is a lot closer then before
>You look down to see her muzzle is planted firmly against your's
>You can feel your nether region start to tingle
>You aren't sure if it's you or her causing it though
>No, it has to be her
>Y-you aren't enjoying this
>Right?

I goddamn love conjoined poners with the fiery passion of a thousand fillies.

I would assume it would only be masturbation if the genitals are connected to the masturbater's nervous system, if it's connected to the twin's it's incest

That's an odd concept for sure. Has siamese been explored much here?
I don't recall seeing nearly anything pony for it.
