This has a double-entendre that is hard to translate. 付き合い (tsukiai, socializing, going out with) is a homophone of 突き会い, the word in the image. The latter includes the kanji 突 (thrust, poke, stab, etc.) and can be used in a sexual sense.HaaaHaaaSenpai, I love you! I love you!Aah!? Senpai's hot thing is...Th... This is... My... First time... So go slowly... Hyaa! Oooh!
