Perhaps it's just me, but, even if we don't see her face and figure clearly, Futahara's wife sort-of looks like Mari ("PROJECT A-Ko"), who in turn was an "expy" (thank TV Tropes for the definition) of Kenshiro from "Hokuto No Ken". Another time and place, had wife-san woken up to realize what was going on, story might have ended like this:
Wife-san: "Omae Wa Mou Shindeiru."
Futahara AND Sugiyama: "NANI!?"
This being a Karma Tatsuro chapter, I was the whole time expecting a twist ending involving his wife. A surprisingly straightforward story this time, though.
I wish I could do 1 handed push ups normally. She can do them in her sleep! He tried to fight her as hard as he could but The Nightcrawler (copyright by Marvel) was too strong. I assume he is used to being dominated in bed.
A...femboy? And also his wife is a muscly woman...Interesting.
"I've been night crawled"? Indeed you have. A rare experience not many get to experience, so savour it.
