this morning you had out on some red lipstick since he loves when you do, you both were kissing and with that left some lipstick marks on his neck, he unknowingly went to his uni classes with them still on his neck

once he came home, he threw his backpack to the side and went around the dorm looking for you, only to find you in your guys' shared bedroom

babe.. you left lipstick marks all over my neck this morning! he says sounding embarrassed
