Imagine your OTP washing their dog on a Sunday afternoon and the dog does not like to be bathed. Person A tries to pin the animal down while Person B washes it. The dog then jumps out of Person A's arms, which sends them splashing into the tub. Person B starts laughing, so Person A drags them into the soapy water as well. The pair have a hard time getting out and keep slipping into each other while the dog merely watches on the other side of the bathroom. Bonus points if it leads to soapy kisses.
A/N: None of these scenarios are mine unless I say so.
