None of them knows how it happened but standing before them is their gender opposite from another world. Ron and Rony were the first to break.
Rony took off her top, and her large tits bounced as she did, making Ron Gasp, "Wow…" Seeing how her ‘twins’ reacted, Rony smirked and bent over as she rubbed her tits, “I know, soft too. Perfect for kissing and sucking. Come on handsome, I can teach you a few things." Ron stripped quickly and jumped onto his 'twin'.
Holly was next she hugged her ‘twin’ getting Harry to moan from his naked 'twin', and his hand landed on her ass, her ass was so huge it was visible from the front much less from here.. "Come on Harry...don't you want to bond with your 'baby sis'?" Harry’s cock was already hard and ready to boast out his clothes.
The Granger had chosen to skip the teasing or seduction. Hermione shoved her 'twin's' large cock right down her throat and tried to see if he could last long enough for her to need to take a second breath, and he was determined to make her need to get off and gasp first. Grangers are always competitive no matter what.
