My absolute favorite part of this whole interaction is that they don't stop fucking her. His cock is inside of her the entire time she's "having a moment". And that's exactly what he should have done. What's he realized she wasn't hurt or in actual mental pain, he should go straight back to pounding his fucktoy.
It’s a pity all of them saw her experience that moment and it wasn’t more intimate. Buddy just had the perfect stroke. The next dance partner is outta luck. She’s on the down part of her emotional high.
