I sleep over at the house of my FWB, naked in bed. I wake up in the middle of the night while feeling a massive load of poop pushing against my butthole! I don’t feel like using his toilet, instead I really feel like sneaking towards his kitchen and finding a more exciting place to shit in without him knowing… His sink looks so clean! Just begging for a thick hot massive load fresh from my tight butthole. I climb up, squat over his pristinely freshly cleaned sink and unload a thick potently smelly load. It smells so good, his whole house is quickly saturating with the smell! I wonder if he will notice… I hope he will. Maybe he will spank me for it… Oh I so love being naughty like this!
