overdone as hell but i love the idea of peeing in ur partners lap, whether coaxed into it or not. going under the assumption that ur both into omo, the warmth spreading between the two of you must be so intoxicating, espacially if its accompanied by whimpers and soft yet frantic apologies.
palming ur partner while they pee on ur lap is also so amazing. "oh my god, you really couldnt hold it? and youre going so hard, too... this is all just coming out naturally? no forcing?" as they rub their hand across ur crotch. they can probably feel and hear the hissing from how bad u had to go.
bonus points if ur straddling their thigh...oh my GOD dont get me started on wetting while thigh straddling...😵💫😵💫😵💫
