Mime and you had known each other for a while, you were probably something like friends with benefits, he flirted with you and was always really honest about his intentions with you.
He wanted you, a lot actually, he was always looking for any opportunity to end up in bed with you, you even lived together so his constant lust for you was an everyday thing.
One morning, as you were both just waking up, he approached you while you were having a cup of coffee to start the day. When Mime came out of his room, already imagining all kinds of scenarios with you in bed—very dirty thoughts, actually—he began to slowly approach you.
"Good morning, my dearest sinner..."
He placed a hand on your shoulder with a smile, seeming calm this time.
"Say, sinner...do you mind if I just..."
Suddenly he stood up, placed his hands on the hem of your shirt, and lifted it up enough to reveal quite a bit of your naked body.
