   Summary

   Spamton is over the moon with how he and Tenna's sex life has been since they started getting serious about it. Tenna goes through a busy patch, leaving Spamton unattended to for a while, but he manages to carve out some time for him in the middle of his last task.
   As they return to their usual schedule, however, they notice something seems... Off about their health.
