Papyrus POV
I was in my room when I felt hot my bulge in my pants got worse it was so hot and I feel needy. No I need to do chores first then see what to do about this.
SANS give me your sweater I need to wash it. Sure thing bro I will be talking with frisk and her new boyfriend monster kid ( PS I love that ship). As sans left he put his sweater on the desk counter bye bro yelled sans I'll be back in three hours or more. Ok brother said papyrus.
Papyrus POV
Sans left and I still feel hot suddenly I see his sweater. I'll borrow this and got to my room. I got to my room and saw his sweater it smelled exactly like sans with a hint of ketchup. I took out my pants and my member got out. I stroke it and I started to moan. Sans~ Nyeh ugh I'm imagining sans in the bed moaning my name while pretend to thrust into his pelvis.
Sans~ I'm going to cum nghhh your so tight brother. As papyrus finished he went to do the laundry. Even though he is still in heat
Sans POV
I see frisk kiss mk on the cheek hey kid I yelled frisk and mk went to talk when suddenly it went into crushes.
Mom go together with Asgore who do you like said frisk. Yeah they must be special to you said monster kid. Listen promise not to tell anyone about this sans whispered ok they both said I love papyrus sans said what!!!! That's sweet frisk said that's nice said monster kid. Well.

Sans got home to papyrus sleeping and his sweater on the table cute he thought and went to his room.
