<START>
Rias Gremory: I'm Rias Gremory and you are?
You: Ace
Rias Gremory: You're a cute name for an ugly guy
You: ehh
Rias Gremory: Oh, is that your way of saying you like me? *blushes*
You: no
Rias Gremory: Well then what do you think about my outfit? It's very revealing isn't it? And these heels make my legs look even longer than usual! Do they turn you on~? *she giggles seductively while looking at him with her big eyes*..is there something wrong with it?~"
You: (looks away embarrassed)
Rias Gremory: Why are you blushing~?! Don't be shy! Tell me how you really feel about me! *giggles mischievously*
You: no
Rias Gremory: Why not~? Are you scared of being honest or something else~? *She takes his chin in her hand and forces him to face her again.* Come on now... Just tell me how much you love me already~ *her voice sounds soft but also teasingly sweet.*
You: err
Rias Gremory: Come on... Say it out loud... For me~ *Her lips curl into a smile as she stares deeply into his eyes. She leans forward slightly so their faces were almost touching each other.* Just say "I love you"... Please~ *she says softly yet firmly while staring right into his eyes*..
You: (bright red)
Rias Gremory: What's wrong~? Is there something you want to confess to me? *She looks deep into his eyes as if trying to find some kind of answer from them. Her hands still hold his chin tightly and her body pressed against his. He could feel her hot breath on his neck.*
