Artist's commentary
I would like something with Thorr (https://imgur.com/jhI8fCS) and Loki (https://imgur.com/cc4isGh) from Fire Emblem Heroes.
Thorr is the goddess of war unaware of her own beauty, Loki is a sultry trickster fully aware of how attractive they both are.
In the first page they try to seduce the summoner, Thorr doing so because she lost a bet, Loki (who won the bet) because she enjoys it. The summoner has sex with both of them, intending to get them pregnant, with them both surprised at how much they want his children. The pleasure causes Thorr to become happy she lost the bet. Loki considers the seduction a success, even if it backfired.
In the second page they are pregnant and lactating whilst they sexually service the summoner. Loki takes the lead and instructs Thorr how to properly pleasure the summoner. In one panel Thorr kisses the summoner whilst having sex with him, Loki bemused at how eager she has become. In another panel the summoner should be drinking the milk of one of the girls. The facial expressions of both girls should generally be smiles.
You can decide the contents of any unspecified panels.
