I would start by saying that from what I have read the term "cucked" is defined in many ways. For us, we see us a Stag and Vixen. At any rate to answer your question the wife using a toy/dildo is very close but not exactly the same. In our opinion there is still some nuances that you cannot get from a dildo and even adding fake sperm. Having fucked the wife both ways after she has been with another man her pussy feels, looks, smells different. It feels hot, looks red and swollen, and you can smell the scent of sex on her. Hard to duplicate that and how you will feel knowing another mans cock was in your wife's pussy.
100% agree....watching my wife with our friend is hot to say the least. SHE gets so turned on watching me watch them. Is very obvious she likes sex with him a LOT, after he's done with a nice hard session sometimes she wants me right after.
Yea....it's more than just her "used pussy"....it's the whole experience. How she's out of breath, her sweaty body, his sweat on her, how she smells, I can taste him when we kiss, how she pushes against me, how she holds me tight, after holding him like a vise just a minute before, how she moans and grunts. It's a huge turn on for us.
The times he's had a long hard session with her, after she's cum and he's unloaded, he pulls out and she's beat, she just lays there legs apart, sperm literally running out of her pussy, she's all red(dark pink) down there and she looks friggin HOT. She's catching her breath, he's laying next to her catching his breath, his dick wet with sex......sounds weird but it's erotic as hell.
Anal....he's fucked her butt quite a few nights, always slow up to the balls pumps. Sometimes she can only take maybe 20 pumps but some nights he goes for quite a while and finishes in her butt hole. She'll flop onto her back and always says something like....WOW.....or damn....or fuck.....
The exciting part isn't her "used pussy" or sloppy seconds....it's the whole aspect.
