yakuta scene also like this one, but it wasn't the one you were after Himitsu wa Kiss de Abakareru http://www.mangago.zone/read-manga/himitsu_wa_kiss_de_abakareru/raw/tr_chapter-24.1/pg-1/
Yes it is! Thank you ヾ(☆▽☆)
I can't get this manga out of my mind because it's funny to me. The seme fucked the uke with a banana? (on a stick). It was the festival and they were both wearing yukata. Then they both orgasm with fireworks in the background. Please don't judge me. xD
