Hi I Apologize For The Vulgarity And Nature Of This

Hi i apologize for the vulgarity and nature of this question but i would seriously like to know the answer. My wife and i saw some pornographic videos of women who injected small amounts of whipped cream into their anuses then pushed it out as sort of a fetish sex thing. We would like to try this but would like to know for sure if it is safe or if there are any health concerns what so ever. We looked online extensively but found only mixed answers. We are not talking about a full enema only small amounts of aerosol can whipped cream. Please let us know what you think we would appreciate a serious answer please and thank you.
