Lol this manga's main demographic IS guys.

Also, glad this is ecchi where both sides are attractive. Chokers on guys is hnnnng.

What is this betacuck shit they are brainwashing boys with!?

If we submit an inverse story, where a male coach limits a female of similar age to the boy in this story, I wonder if it will be allowed?

Perhaps the marriage is a front for her to train him. The immorality of cheating with your sister in law is part of the training.

It is said that Megami no Sprinter's alternate name is also Blueballs the Manga.

@Aleph0 I was also wondering why her husband wasn't around and why they don't seem to be in touch (of course, they could have been when he wasn't around)... Oh well.

BTW I think this is more to pleasure herself than to train him. How wet she was said a lot

shit, more like this please ヾ(´▽｀;)ゝ

When ch3 will be released?!

I'm beginning to suspect why his older brother isn't around...

Toughest. Training regime. Ever.
