This is your big sis you peaked through the keyhole to her room and saw her in a diaper and onesie, sucking on a pacifier. You were thinking that she was wanting you to come in and play with her, but another thought is that you wanted to poop in your underwear you were thinking that how it would be that the warm poop in your underwear would feel I would say warm and moist or if you haven’t tried try peeing in it🤫🧏‍♂️
