Summary
Tenna tangled his fingers into his hair and feathers, strands of both getting painfully trapped between metal joints as his head was ripped back. His eyes shot open in shock as a single sharp claw lifted an eyelid, and through tears and overwhelm he was forced to really look at himself.
Sweaty hair and frazzled feathers clinging to his face–flushed an unhealthy red as he was made to take it, over and over.
═══
Spamton goes into a commercial holiday fueled heat and tries to smoothly hide it from Tenna. While actively begging him for sex.

Summary
Weeks before Kris and Susie would begin their chalk-retrieval quest, the laptop is returned to the Dreemurr household.
Mr. Ant Tenna’s unexpected comeback sets all of Cyber City abuzz with excitement—with the exception of one particularly resentful puppet. Spamton G. Spamton desperately craves revenge against his old partner, but to his horror, it seems that Tenna too is hungry to settle old scores.
With nowhere to run and few places to hide, Spamton must finally face his past. But can he scheme, sneak, and scam his way to vengeance before the Lord of Screens' mysterious plans catch up to him? Or will his efforts land him in far greater danger?

Summary
Alternatively Titled: Spamton's Chicken Noodle Soup for the Soul.
After so many years of static and noise, Spamton’s mind is finally clear. In the quiet that follows, he begins to gather the scattered pieces of who he once was, trying to rebuild something real with Tenna right beside him.
For the first time in forever, the universe seems to give him a second chance.
