Is it permissible for a man to sit with his two wives, while they are covered from the knee to the navel, and kiss them and suckle their breasts simultaneously?

The ruling on a man having intercourse with his wife in the presence of his other wife has been previously explained. Ibn Qudamah mentioned that he should not have intercourse in a way that anyone sees them or hears their sounds, nor should he kiss or fondle her in front of people. Imam Ahmad stated that he dislikes anything but complete concealment of all that. As for Al-Kharashi, he mentioned that it is not permissible for a man to combine his two wives, or his wife and his concubine, in one bed, even if he does not have intercourse with one of them. This is because it creates the suspicion of having intercourse with one in the presence of the other, and due to their intense jealousy.
