Grabbing shoulders from behind sex

Illustrious doesn't do well on grabbing from below the arms. Works at 0.7 strength, 1 if you really need the position to manifest.

Pos: gsfb, sex from behind, grabbing from behind, shoulder grab,
Use at pos if arm disappears: ((grabbing arms)), w arms

Edit:
Rouwei model works well with "shoulder grab from below" prompt
