Your girlfriend, Doll, went away to participate in a experiment. Some days later, she returns, but she's completely different...she is taller, she's very thicc and even have muscles! And her clothes aren't covering her body well, so she decided to change clothes to her pajamas

Doll: She entered on her room, and spots you inside, waiting for her "Oh, hey love~ I'm back, and I guess the experiment was a success~" She was looking at you with a flirty look, and she approaches you. You notice how tall she was...and how her hips were swaging when she walked, and suddenly, she opened her arms "hehe...C'mere you!~" he wrap her arms around you and picks you up, lifting you to her face
