Narrative:
Aircraft X was a departure off of apa who I got on a 320 heading climbing to FL120. I then got another aircraft who departed apa also on a 320 climbing to FL120 (aircraft Y). I climbed aircraft Y to FL230 and was climbing through an arrival descending into den. I was watching his climb rate to ensure separation there; and sent aircraft X direct to baylor thinking I had already climbed him to FL230. As I was watching aircraft Y climb; aircraft X asked for higher. I saw he was level at FL120 and issued a climb to FL230 and a turn to 320 [heading] to avoid the 13;500 MVA.he didn't do either of those things quickly; so I issued a turn to 330 [heading] and then further right to 350 [heading]. Aircraft X entered the 13;500 MVA approximately 3/4 of a mile climbing out of FL132 before exiting into lower MVA again. I didn't issue a safety alert because I didn't feel that he was in unsafe proximity to the terrain and was doing all the maneuvers he could do to climb as per the situation. I feel like a complete idiot letting this happen with just two aircraft on frequency. Don't get complacent!

Title: D01 TRACON reported an aircraft not following directions and entering a lower Minimum Vectoring Altitude (MVA) for a short while.
Narrative: Aircraft X was a departure off of APA who I got on a 320 heading climbing to FL120. I then got another aircraft who departed APA also on a 320 climbing to FL120 (Aircraft Y). I climbed Aircraft Y to FL230 and was climbing through an arrival descending into DEN. I was watching his climb rate to ensure separation there; and sent Aircraft X direct to Baylor thinking I had already climbed him to FL230. As I was watching Aircraft Y climb; Aircraft X asked for higher. I saw he was level at FL120 and issued a climb to FL230 and a turn to 320 [heading] to avoid the 13;500 MVA.He didn't do either of those things quickly; so I issued a turn to 330 [heading] and then further right to 350 [heading]. Aircraft X entered the 13;500 MVA approximately 3/4 of a mile climbing out of FL132 before exiting into lower MVA again. I didn't issue a safety alert because I didn't feel that he was in unsafe proximity to the terrain and was doing all the maneuvers he could do to climb as per the situation.
