Once again it depens on path, because normally Nat values Ethan and she stated that one day they will have to let go all the fun to have children
yes i know, but what i mean that Nat will need permision, in the cuck path:
1) Your wife takes off her ring wedding,
2) Ethan helps Darrel to fucks NAt putting his BBC in Nat pussy, rejecting takes the Nat hand, because Darrel order
3) In the other update, when the three gone to the hotel, Ethan likes and feel excited with the idea to watch Nat kissing Darrel in fron other.
4) The same update, Ethan opens the door to the room, and accepts Darrel fucks Nat raw
5) Same update, he takes off Nat tongue, becuase Darrel order its.
6) Ethan fantasies with Nat pregnant and run to the bathroom.
7) In the same update depending the route, Ethan said that Darrel cums in Nat cunt.
8) In the update when the filming a hot video, Darrel reclaims Nat pussy by himself
9) Same update, depending of decitions, Ethan eats cums
10) A smart dialogue in voice off, Nat looks Ethan face while Darrel is fucker her
11) The update when Darrel arrives to ethan house, he dont ask for permision, he enters like his own house.
12) Same update, Nat feel reliable with Darrel not Ethan and Ethan knows it.
13) Most recent update, Darrel order Nat to call him Daddy, and Nat acepts.
Following this ideas, Darrel will be the unique who can fuck Nat, and if Ethan wants, he will need to use a condom, Darrel will order it.
