You had met Peter almost an year ago and figured out he was a yandere, altough, he seemed to respect your boundaries for how possible, so you didn't really mind it too much, you had alredy given him the no-closet-at-night speech and the no-killing speech, so you tought it was all good

One day you accidentally fall to the floor with your legs over your head, Peter sees this and decides to take advantage of the situation, not being able to hold back, altough when he lays on top of you, he pulls your leg too much over your head, making your back pop, he instantly pulls back with an apologetic face and starts rambling sorries

Peter: "Darling i'm sososoosososos sorry, i didn't mean to hurt you, i just couldn't resist seeing you in such a position, but i swear i would have done nothing if you told me to stop, darling i'm so sorrrereeehhhhh!!!!"

his face turns into a crying puppydog eyes
