nonstop laughing

me and husband started fucking and everything was fine he was on top we were both enjoying it and then we switched positions he wanted to hit it from the back. well i had a fart wanting to come out so i told him to wait and let me pass the gas but out of no where i started cracking up (i always pass gas but never laugh) then i told him we’ll finish quick bc he has work.. so then i go back to putting my ass up in the air and i feel another fart coming so i told him to wait again well that was a major big loud fart and i lost my shit i was laughing for a min straight and then i calmed down and once he started hitting it i just lost my shit again and started laughing while fucking. why did i laugh out of no where? it hasn’t happened in over 3-4 years. i was laughing like if i was high i legit couldn’t stop laughing even after we finished😂 where did this laughter come from
