2nd mortgage holder recourse if I maintain 1st mortgage paym

I just concluded a ch 7 filing in march. I did not re-affirm 1st or 2nd mortgages. property value is $105,000, first mortgage unpaid balance is $99,646, 2nd mortgage unpaid balance is $35,000. I just received a loan modification agreement from 1st mortgage holder that until yesterday I did not know was an option available to me. I might be able to afford to make the 1st mortgage payments under the modification agreement, but it is very unlikely I can also continue making payments to the 2nd mortgage holder as well due to financial constraints. I really am wanting to understand, considering the equity situation as it is, what recourse the 2nd mortgage holder would have if I maintain residence in the property, make 1st mortgage payments however do not make any 2nd mortgage payments?
