My wife has had the same fantasy over the years. She enjoys rough sex and being held down as she resists somewhat, it’s gotten a little more aggressive with time although it’s been a while since she’s wanted it like that. We did a couple role plays where I’d surprise her when she would come home, she’d know what was going to happen but always wanted me to not tell her the day and would urge me to find someone that could help make it more realistic. She hasn’t brought it up in a long time but it was a very arousing fantasy for her.
