I mean, if anything makes that scene any better is that there's nothing super explicit about it. They position themselves with their clothes on, there's a cut to a different scene, and when they cut back they're already done. Yes, it's rape, but the way people talk about it you'd think it was much more hardcore than it really is.
The thing about Revenge of the Nerds is that there was tons of backlash even when it was new. The sequel barely has any sex in it at all by comparison, it's because the creators caught a fair amount of grief so they had to make Part II a tad more family-friendly (there's still a scene where they all get stoned though lol).
