Project Series

Project Arousal is a wild, fun concept for Second Life® (SL): sex anywhere. Want spontaneous, ravishing lust that sweeps you off your feet (and onto the floor) without hunting for a private spot? In real life, that kind of abandon would probably get you arrested. In SL, it’s at worst a ban. So, Project Arousal takes things to a whole new level of passion… or trouble, depending on your luck.

What are we talking about?

There is a summary of this article at the end. If you are in a hurry or only a little curious, jump to the last page and scroll down.

Back in 2020, I wrote an article called Second Life: What is Project Arousal? (Review-Tutorial) when I was just figuring it out. The TL;DR: it’s basically a sex toy system. It lets you have sex anywhere scripts are allowed—ideally in places that also permit object rezzing.

Project Arousal 2 (PA2) is a full sex system with tons of add-on toys. The base “engine” supports a huge ecosystem of extras. As of February 2026, the core costs L$2,150 (up from L$1,000 in 2020—not cheap, but you get a lot). By itself, it’s enough to get started, but you’ll probably want more. The creator (Caeil) offers around 78 official add-ons, and searching “Project Arousal” on the Marketplace turns up over 500 related items. Plenty to explore.

A key incentive for its use as a partner can initiate sex by simply clicking the avatar. HUDs are not required once the system is learned. Similar to clicking an RLV collar. Simple.

I keep finding things I either haven’t known about or haven’t taken the time to… study… play with… whatever. One of these is a set of related toys all named Project something. I think Project Arousal is somewhat known. It is the core engine of a series of sex toys with a strong anime flavor, that supposedly makes SL sex more realistic. Sure. Of course. But, is it fun and what is meant by more realistic? What if you aren’t into anime?

When I started this a couple of weeks ago, SoCal was drowning in major rain like I hadn’t seen for at least a couple of years. It was a good day to stay in and play with sex toys.

What it is…

First, there is the Project Arousal Engine (L$1,000). This is the core of the Projects’ system and is mostly required for all the various parts to work. But some items in the Project family are standalone. This core mostly provides sounds and facial and body animations denoting arousal. The number of body brands supported for some features is very limited. But as a female with a Slink body, I haven’t found that to be a problem. I first suspected it might be for males. But as I learn more, I think it won’t be.

This core part of the system does not need to be rezzed. You simply wear it and your partner wears it. There is a guest HUD in the PA package you get. It is for your partner without Project Arousal. The PA engine can be used in No_rez areas. This is and isn’t true for some of the add-ons. Read the promo material carefully to know which is which.
