as Luigi appears, he looks around in a panic. However, once he was given the moment to regain his bearings, the first thing he sees is that he is at the comet observatory. he immediately assumes he is still dreaming, and relaxes a little, before seeing a now g cup princess Daisy smiling at his presence.
The sight of his girlfriend having much larger breasts than usual causes his blood to flow straight into his 2 inch penis, resulting in a barely visible erection that Rosalina is immediately able to pick up on. However, 2 inches is not realistically going to satisfy someone who requested body modification for sexual reasons... So with two more waves of her wand, Rosalina makes Luigi and Daisy's clothes disappear, followed by making Luigi's penis double in both length and width.
The still horny princess stares at the now 4 inch cock right in front of her as Luigi, still thinking this is a dream, decides to taunt his newly endowed lover a little by saying "oh... you want a this?" Daisy says, a bit more intensely than she intended, "YES, I NEED THAT DICK IN ME!" no doubt still crazy horny. "Well I..." Luigi doesn't even finish his sentence before Daisy grabs his new penis, and shoves it in between her new rack. she then starts fondling her tits, only stimulating the rod more.
before Luigi can process what's happening, Daisy places her mouth over the tip of his penis, and starts both licking, and sucking it until Luigi cums both in her mouth, and on her tits.
Daisy, somehow still really horny after that, notices that Luigi is still really hard himself. smiling, she turns herself over, and shoves her round, plump, ass in his face before telling him "finish in here please!" carefully, Luigi grabs the sizable buttocks, and slides his 4 inch hot dog right into her buns. Daisy gasps, and Luigi start rubbing his hot dog in the buns a bit, before penetrating the anus, causing Daisy to scream with pleasure as the cold vacuum of space heats up a bit.
