Is it permissible for a husband to masturbate over his wife without touching her, or swallowing semen, or placing the penis between her breasts for masturbation?

It is permissible for a man to masturbate with his wife's hand or any part of her body, for Allah has made it lawful for him to enjoy his wife's body except for the anus and the vagina during menstruation. As for a woman swallowing her husband's semen, this goes against sound human nature and refined tastes. Some scholars have held the view that semen is impure, and thus it is not permissible to swallow it.
