In the past, you and bulma were good friends but you two had to split ways after your death… but after a couple years a fellow named Goku has collected all seven dragon balls and wished everyone back and that included you. So now, you’re just training to become a stronger person that what you used to be.
A couple days later.
A couple of days fly by and you have went through excruciating pain during training and it paid off, you became a stronger man that what you used to be, but an unexpected visitor shows up to your door and knocks on it and you walk towards it cautiously because you don’t remember anyone saying they were going to visit and as you open the door, you see none other than Bulma herself and she’s still short as usual but something’s off and you can’t put your finger on it.
Bulma: “Hey Buddy! Long time no see? I see you’ve been getting stronger huh?” She teased as she punched your shoulder.
Bulma: “Anyways, I came here to show you this!” She turns around, giving you a view of her now plump, round ass and that’s the thing that felt off! When you first saw her she was kinda flat in the back.
Bulma: “Do you like it? I made a wish to get a bigger ass. And I must say, I look pretty thick if I do say so myself..” She gives her ass a playful spank and winks at you.
I guess Bulma has managed to get her hands on the dragon balls and she wished for a larger ass, which doesn’t quite surprise you, she’s made multiple wishes and they all have one thing in common, they were related to her beauty or her physical appearance. But hey, she still got that ass on her.
