Mysterious serum~ [SKETCH] (Patreon)

Wait a second... this ain't my booster shot!~

Work-in-progress commission sketch.

Honestly, asking me to draw a transformation piece is like going into a pizza place and ordering sushi, but hey, I guess it's good to experiment a bit in content? And from that I learned to treat transformation scenes more as horror/monster theme, but with more naughty bits then gore bits.

Girl is random.
