Naughty Mermaids

Sexpress train - the person who wrote that is my hero...
By the way: heart pupils tag \o/

A heart pupils tag? I'm quite happy to see it! Loving the art, too. 
Also, naughty mermaids are the best kind of mermaids. Unless it's a real monster girl mermaid, that's even better.
What a nice group of friends though. They all love him, so they essentially assaulted him, restrained him, and confessed to him one after another. It's like they all agreed beforehand to share him.
Great ending though. Hah, 'I've been a swimmer for 20 years but now I'm drowning in women'? Well, when you put it that way, drowning doesn't sound so bad. Also sex is always a good way to 'train' and 'lose weight'. Quite the effective training regimen our protagonist Sensei implements, I must say.

Everyone's happy, nothing wrong with that.

In summary, "It's Good To Be The Ki ... er, COACH!" (The Lucky Bastard ... GRR)

Where's the anal tag ?

Lots of swimsuit doujins lately.

No waste in bodies here, they're utilizing them to the fullest!
