ya like papyrus bein bounced over his bros thick asf cock like a cargo truck on a shitty road coming over & over again frm bein used as a fuckhole … + sans doesnt even wash him out aftrwards so. hes just left with this crusty ass mess when he. wakes up but its not like sans cares so he just accumulates cum layers for a while
good siblings’ day activities: drive-in movie, it’s got cars, it’s got stars, it’s got a film you both enjoy
bad siblings’ day activities: sitting in the backseat wrapped up in a blanket that ends up protecting you not from the cold but from your fellow movie-goers’ eyes as you very subtly feel each other up underneath it, you’re both pretending to be focused on the movie and it’s therefore okay to not say a word or even exchange a look about it and to rely entirely on direct soul feedback
well, there’s also the huffy noise papyrus makes when sans keeps pressing into that one spot on his collarbone and then moves to kiss it and they have to dive almost entirely underneath the blanket to stay… “inconspicuous” might be the wrong word to use
non-suspicious
