There’s no straightforward answer to this question.
‘It depends’ - on factors like your wife’s physiology, her genitals, whether condoms are used, how much lubrication, and what type is involved, the number of men involved, and so on…
We have a lot of experience in this realm - gang bangs are KK’s favorite.
Most of the time, during the gang bang I am assisting, and at some point will participate. KK’s not ‘loose’ in any sense, but her pussy is generally open, sopping wet, silky-hot, and it is easy to penetrate her, and easy to penetrate her deeply.
The couple of times KK’s pussy has been loose involved extreme kink - fisting and the use of a huge dildo, along with her pussy having pleasured a half-dozen big, hard, cumming cocks. KK was gaping, both ass and pussy for a half-hour to forty-five minutes after it was over, and needed lots of after-care.
We always have reunification sex after these events - but it sometimes is several hours to as long as 24-hours after, depending on KK’s physical condition - sometimes, her hips are sore from the activity, and being spread wide for so long, other times, particularly if condoms were involved, she will feel sore and irritated, not in the mood for penetration. In the reclamation fucking session, KK’s pussy is as tight and nice as always - not loose.
