I am also looking for swiging games since ages.. It's hard to understand why all devs avoid swinging and keep falling into cheating or hot wifing or .. NTR-cuckolding.. All you can find are short scenes of swinging like the one in this game with only static poses and no animation and also with several choice you get to NOT do it. Apart from the 2 games you mentioned (whereby Dreming of Dana is the best.. goes even in direction "poliamory") , you will find a whole path with a quite nice swingers ending in LOP Club Velvet Rose but even here the swingers scene has no animation and is again unfair to the man.. the wife gets fucked like hell and he only gets to lick the pussy of the other wife.. There is one more swinger path in LOP_GOLD_Living_With_A_Nympho but with the same "restrictions" and another one i found in Living with Temptation (or was it "Eleanor"? - not sure anymore but 1 of these..) but again unfair .. the wife gets gangbanged in a swingers club and as an option also after she left the club with several guys in their limo, while the MC gets only one girl to fuck and then just "watches" his wife getting gangbanged. Oh and he also fucks his wife as 1 of the 5.. During the game the wife gets 2 more gagbangs but in the swingers club, thats all , as i said before.. And there's 1 more swinger scene in "Happy Marriage" unfortunatelly of the same kind: the wife gets filled by 2 men in all her openings while the man .. you guessed.. just LOOKS while having the wife of 1 of the men on his lap fucking him , which he however doesnt seem to care too much about coz yes sure.. he is busy WATCHING his wife get fucked so nice and hard..
This is the present situation related to swinging in these games . My explanation for this is that most devs as well as most partons are YOUNG or .. very young.. and the idea of swinging generally is something that comes later , when yo get a little older and maybe you kinda had enough of the same pussy and ass for 10 years or so, no matter how good that pussy or that ass is .. and your partner got also enough of your (probably huge) cock and you both decide that you want to have some more fun with some other pussies asses and.. cocks.. Of course watching your partner fucking next to you is also a hot theme by swingers but unlike the way "open relations" are handeled in most of the present games, swinging is a FAIR GAME! You give your woman to another man and he gives you his woman in exchange. Thats fair and good! And damn sexy too.. It's just not something for teenagers to dream about.. Maybe we have to wait for the devs to grow a little older..
If anyone knows other games with at least 1 scene of swinging please post the name here. Thanks.
