Still...I kind of feel bad for both him and her sister, but I can't exactly say he's entirely blameless.
If he just, I dunno, stood up to her or something rather than being so spineless, things might have been different.

In the end, he got pegged, trained...And that ending? Makes me wonder what her reaction would be when she finds out...
By the way: forced tag is missing.
