Faith in the God of Carnal Desires - I Give Tentacle a Body -

Here's a doujin with Suwako and pure tentacle rape goodness. It's another in the series by Happiness Milk, and that person makes some good stuff. It's pretty much just constant loli tentacle rape all the way through. But I gotta say, you don't often see women running up to tentacle monsters begging them to rape them.
