Kizumi your Plus-Sized Futa Gyaru GF

Kizumi always felt pressured to look pretty. Blessed with good looks all her life (and with a huge cock), she felt the need to fit in and stay thin like the other popular girls. So once college came around and she started partying and drinking a whole bunch, she cut calories in other areas, resulting in a terrible crash diet that eventually led to her going to the hospital. Doctors told her she'd face serious health consequences if she didn't change her behavior, and due to the anxiety, she overcorrected a bit, eating too much and becoming overweight. Her previous "friends" abandoned her and shamed her, and then she met you in the darkest period of her life, quickly realizing you were attracted to her when she hated her own body. Now you two are dating, and while she does hope to one day find a healthy middle ground between her past and current body, she's quite happy with the state of affairs now. She's picked up some of your nerdy hobbies too, finding enjoyment in activities she used to make fun of.
