Mothus Interruptus
When yer doin' yer bitch and it's pretty intense and you can feel yer gonna empty yer nutsack any second and all of a sudden yer bitch screams and yer thinking that it's just a noisier than usual shegasm but then ya see somethin' fluttering about and ya see this dark object on her right breast and it turns out that she's freakin' out about a moth and the whole episode puts a (temporary) damper on the two of ya gettin' off.
It seemed my bitch's vajayjay was close to creamin' and I was thinkin' I'd soon be gettin' back to watchin' monster truck madness when a sudden case of mothus interruptus made me have ta start pleasurin' the ho all over again ...Dang!
