The lure of pale blue lips

Adolscent Loki is captured to be a whore. His body looks fragile, but it can bear much.
Due to his shape-shifting abilities he can transform into a female to satisfy every desire of those who pay. A night without protection spell costs most.
Although his pregnancies almost kill him, he still loves the children who are taken from him right after the birth.
Thor finds out about his miserable existence and tries to help. A child is conceived, but Loki was also sold to Malekith the day before.
The expected father is allowed to do with Loki whatever he wants. Only Thor's loving care is the reason he endures the pregnancy while Malekith tortures the young god in any way possible...

The cover is me as prison Loki.
