lots of comments that they BB'd...
likely and plausible...but it's also possible that the condom didn't work...
97% effective, means 3 in every 100...
that's 3 in every 100 condoms, not 3 in every 100 times you will have sex
maybe they did BB - lord knows she would have agreed, but maybe he was worried about this outcome and didn't (and got fucked over anyways)
