aftercare from light kink during a swap, who runs it?

first time doing anything kink-adjacent in a swap setting, the other husband used a blindfold and some very mild impact play on me with my partner's and his wife's blessing, all consented and lovely. afterwards i was a bit floaty and emotional, definitely needed some quiet down time. but i didn't know who was meant to look after me? my own partner? the bloke who did the thing? everyone? in the moment my husband stepped in but the other guy looked a bit uncertain. for those who mix kink with swinging, how do you handle aftercare across two couples?
