   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.
