Trapped by My Dark Twin Stepbrothers

"Hate us while you can."

Komari's two stepbrothers "take care" of her every night until she's ready to pass out. Her mother remarried, and she gained two brothers--the calm and kind Tenma and the nonchalant Toma. One day, however, the two discover her secret... In exchange for keeping it a secret from their family, Komari becomes the twins' toy. "There's no need to be afraid." "Stop moaning just from getting fingered." "Looks like we made you a woman!" "That expression of yours is just turning us sadists on even more." It's open season for these two hardcore twins!
