Back-to-Back (Her Then Him Immediately)
Intensity level: Wild
She finishes, and before she's fully come down, he finishes inside her or elsewhere. No pause or transition. The overlap is the point.
How to try this
Bring her to orgasm first, and before her body has fully come down, before the aftershocks fade, he finishes immediately after. Inside her or otherwise, the key is no pause between her finish and his. The overlap of her orgasm's tail end and his beginning is the experience.
Why couples love this
The overlap of two orgasms, hers still echoing through her body as his arrives, creates a sensory collision that's greater than the sum of its parts. Her post-orgasm sensitivity meets his peak intensity, and the shared timing feels like the ultimate synchronization.
