Midnight Snack (слэш)

For the ITAB prompt:
Rare Bottom!Bucky NSFW prompt! I'd love the boys in a long term relationship but Bucky is feeling a little neglected. He thinks trying out a new kink will spice up the relationship so he sends Tony a raunchy video of himself playing with whipped cream. Tony abandons work and goes to play with Bucky. Pretty much what I want is FELCHING with whipped cream. I want Tony to eat whipped cream out of Bucky's ass, fill it up with more whipped cream and then fuck it. That's pretty much it.
