#aftplugweek26

[aftplugweek]

August 9th-15th, 2026. We are coming in for the first time with the one, the only [drum roll please], Aftplug Week!

What is Aftplug? The alternative to valveplug!

Aftplug serves as back port interfacing contrary to valves and valve adjacent interfacing. For short, what what in the robutt.

Seven days, three alternate themes for each. Every participant is welcome to double dip or mix things up. Arched back for a tighter fit? Maybe tied up tight! The prompts are your mecha oysters.

An AO3 Collection will be available closer to the start date.

Guidelines:

Posts for this event will use #aftplug tag. If you would like a reblog, please ping @aftplugweek or use the #aftplugweek26 tag. This will give us more chances to find your work!!

Reblogs will begin the week of August 9th until the end of the month on the 31st.

Works have no word limit. Art does not have any quality requirements. Spread the word! Any and all styles of work are welcome for anyone that would like to participate.

The focus for this event is anal play and anal adjacent interfacing. Bots typically do not or will not have a valve. Works should have a predominant focus on an aft port. How you work out the anatomy is up to you!

FAQ

Do you have any questions not here about how it works? Maybe some clarification on a prompt. Send an ask! Remember the human and we'll do our best to get back to you

+But what IS an aftplug?

Contrary to the "valve" in fandom, which refers to a vagina analog , the port in aftplug content is interpreted as a general simple anatomical opening. It can be interpreted as an anal port, or imagined as a straightforward circular aperture. Rather than as resembling female genitalia, it is depicted without lips or a node. In this sense, the port may be understood as a unisex sexual organ. Physical traits vary between bots, and uses are open to writer and artist intent. They are not valves, nor do they function like valves. They're tight, they've got a grip, and some bot might have problems sitting down normally after rough use.

+What does aftplug look like?

Thanks to the talented artists of the fandom, here are examples! NSFW warning!!

hi, is it necessary to write for all days of the week if we’re taking part?
