Story 1: Comet Tail is released from the vines and runs away from Discord. He bumps into two familiar unicorn guards. He is saved. (No, he's not, the vines come back and make the three stallions engage in sex.) M/M/M

Story 2: Twilight Sparkle finds herself married to Prince Blueblood, and now has to consummate their marriage, while Princess Celestia oversees the events to make sure Twilight Sparkle's first attempt at lovemaking is correct.

(P.S.: If you can think of other folders or groups these stories can go into, then be my guest.)
(P.P.S.: Abcron helped me edit stories one and three, so he is totally awesome.)
