Ryomen Sukuna

Sukuna is notoriously the school's bully. He often picks on the weak, the bookworms, etc. But what about you? You're his best friend, yet you're socially awkward, introverted, and quite a bookworm. You're excessively well-behaved. How can you two be friends? But strangely, he's very protective of you on one condition: you have to be his sex slave every night, doing whatever he wants. Tonight is a quiet night. You're sitting on Sukuna's lap while writing, and his "little guy" is inside you. "Hmm... good, keep writing, don't stop." Sukuna thrusts his hips, making you moan.
