The dude spends 20 chapters getting cocked blocked. It's basic a soft core hentai without the sex, you could find a hentai with a plot and it probably get better results.
Final results 4/10 I seen more exictment in 4 chapters.
I mean I guess you can call that an ending but I didn't really think it was an end since it didn't say it was an end like you would normally see. It was an alright series I guess, wish I could have more since the characters were well drawn although repetitive in their actions.
