What is your interpretation? My wife likes to fuck herself with her dildo and then after cumming she wants me to fuck her. While I'm fucking her she likes to lick the dildo and then she'll put the dildo up to my lips and have me suck the dildo while she watches intently, she'll feed me the dildo as if a guy is fucking my mouth. This has happened many times.
Would you interpret this as she has a fantasy of watching me suck a real cock?
Maybe she is cuckolding you with a dildo, fantasizing it's another guy. Which would you prefer? The dildo, or another guy in bed with your wife and you?
