Help! Should I Allow My Wife's Sexy & Heavily Endowed Friend To Stay With Us?

Recently, my wife's female friend got a job in Lagos and has asked to stay with us for a while. The babe is single and heavily endowed. She's a serious temptation o! Hope I am taking the right decision by letting her stay. I don't know if I can overcome her should she decide to "make a move". Guys, please advise me.
