Alright so this was a lewd manga.
Two girls are going at it and one uses a dildo to stick in the other girl and the other girl was like "no way! Thats too big! It won't fit!" (Obviously though, it fit)
And the first girl is like "see I knew it would fit!" While the second girl is really surprised and kinda scared saying stuff like "no way!"
And thats when the first girl asks if the second girl was a virgin and the second girl said yes.
First girl feels super bad for taking her virginity in such a crappy way and makes up to her.
Sorry that I wrote it so confusing but I'd really appreciate if I could find this one again.
