If the condom breaks, I will get pregnant

Going to a cosplay event as a Tavern Wench, I met up as I had planned with my fuck buddy who was being a pirate for the day. After a great day my fuck buddy, my husband and I all headed back to a hotel room so my fuck buddy and I could have sex while my cuckold husband watched and filmed it. But as I had forgotten my birth control pill the day before I had to ask my husband to go and get a packet of condoms. My husband was real nervous about my getting fucked with just a thin layer of condom between my pussy and my fuck buddy's sperm. Given the time in my cycle there was a really high chance I was fertile.
