I propose a new type of common envelope jets supernova (CEJSN) events where instead of a single neutron star (NS; or a black hole; BH) a tight binary system of an NS and a main-sequence star enters a common envelope evolution (CEE) with a red supergiant. The NS and the main-sequence star of the tight binary system merge inside the red supergiant envelope and enter a CEE of their own. The NS accretes some mass through an accretion disc and launches jets that explodes the main-sequence star. I estimate that the two jets that the NS launches at this phase carry an energy of $\approx 10^{52} {~\rm erg}$, about the same order of magnitude as the energy that the jets will carry when the NS or its BH remnant will enter the core in a later phase. For that, I term the entire event a double CEJSN. The outcome of the double CEJSN is a very long, months to years, and very energetic event, a total energy of $\approx 10^{52} \!-\! 10^{53} {~\rm erg}$, that will be observationally classified as a peculiar superenergetic event. I crudely estimate that new transient surveys should detect about one CEJSN event from a triple-star system per year.
