cyber siblincest

When two related cyborgs cultivate their cyberomance over the internet. They have long discussions over facebook chat, often after drunken parties, but when they see each other in real life, sentences are usually two words or less.

Sometimes they cannot recognise each other in real life unless fashioned akin to their profile photo.

Nat on internet: how come you went all narcoleptic on me last night... i was getting so close to it, i almost got you to tell me the whole reason for 'chad' (since you wont tell me sober)! How you feeling this morning anyway? Wanna cyber siblincest?

Nat in real life: sup.
