One of the ones I enjoyed was "After School Sex Slave Club" by Tuna Empire, unfortunately only 1 vol. was published.
Another is "A Wish of My Sister" from the Aki Sora artist for Incest and traps ...and "Read Me!" for futanari, Cheerful Eros Project by Yuzuki N' Dash, Midara by Yumisuke Kotoyoshi. Can't remember the tags from the top of my head.
