There's already a date for a double penetration with my wife

Hey friends, I want to tell you that after the trios I had with my wife, I insisted on doing a double penetration one night when she was having sex with me and putting it in four while she was taking it out. I started stimulating her bum, which is very tight, and managed to get a finger in, making her moan. Then I told my wife that I would like to do a double penetration, and her response left me very anxious and desperate. She said that if I did it, she would let me fuck her sapito and bum, and whoever was going to be the candidate would have to be big and serious, as a gift for my birthday. For me, it will be an exciting way to celebrate my birthday in November. I promise you that when we do it, I'll record and upload a report with photos. Just listening to my wife's words about knowing my fantasy would come true made me feel more successful and gave me more drive until I couldn't take it anymore and had to discharge all my cum into her sapito, leaving me exhausted. We fell asleep the next day, unable to contain our joy because of what my wife said. Now, I'm on the task of finding the candidate to have sex with my wife. So far, I have two options, but I don't know which one to choose - one is an ex-boyfriend of hers who, by the way, my wife told me she's had sex with many times and that he has a bigger cock than mine; and the other is a friend of mine who showed me his cock and it's even bigger than mine. I don't know which one to choose.
