since you want some Lucifer/Abel food
One where Lucifer should be at the meeting, but while everyone is waiting he's eating Abel out .
Or where Abel goes to hell (whatever reason) and gets stuck in a hole wall and Lucifer is just there at the right moment (bonus if Cain's at the other side)
A good king deserves his fine gourmet even in important diplomatic meetings. He'd be the more audacious to eat him out before and during the meeting as Abel stands in as his spokesman. The court wonders why he's so jittery and noisy during that meeting, 'Abel must have been running a fever, poor guy.'
It's moments like those where Lucifer appreciates his short height, perfect to tuck himself under that dress of Abel's!
Also, stuck in the wall trope is soo good! 🤤 Why get curious if you aren't intent on getting yourself stuck? Abel can't help it, and it's a perfect bait for Luci to further keep him on display (with, of course, Cain as a perfect audience member!) You can bet Cain makes use of that wailer of his, the perfect length warmer as Abel's perfectly sandwiched between the two guys <3 <3
