Lawlight Light is a sex robot

[dnk_mod]

L requires an assistant when Watari grows older and gets an android (Light) who is the top of the line. However, he accidentally finds the android's secret function - full sexual subservience to its owner.

Kinks are dom/sub (very subby Light, plz), techno stuff, and unequal power dynamics. Dub-con because...android consent is muddy, but no pervy L, just interested and horny if possible.
