Wait for her to make a move.

You two stand silently in the rain, eyeing each other up until she giggles and raises her pinky finger and wiggling it around.

"H-Hey, it's bigger than your pinky!" you say, trying to sound confident, but your eye's betray you and reveal your inner doubt.

"I already told you, let me be the judge of that," she responses and begins walking toward you, still waving her pinky in the air and smiling. Her breast bounce with every step she takes and her hips sway seductively. Her figure is perfect in every way, and your dick knows it, but you try to stay focused on her eyes. You manage to see her glance behind you, as if surveying the surrounding area, so you suspect she will charge at you again. Knowing you can't keep your footing on the ground, you decide to try and outsmart her, so you wait for her to lunge at you, taking the time to admire the rain running down her body.

You see her prepare to lunge at you, so you lower your stance as if bracing for the impact. A devilish smile crosses her face as if to say she's coming for you, but you won't fall for that. As soon as her feet leave the ground, you lunge down towards her legs.

"Wait, NO!" she yells as she realizes what you are doing. "You BITCH!" You don't let her words stop you as you collide with her legs, sending her face first into the mud next to you while to hold onto her legs, the mud feeling nice against your fully erect member. She wiggles around as much as possible, trying to escape from your grasp, and it is quiet difficult to hold her because of the mud. You flip her over, revealing her body entirely covered with mud. Its a shame, really, because the mud obstructs her perfect tits. She coughs and begins kicking at you.

"Hey short shit," she calls to you, her kicking momentarily stopping. "Hold onto this!" And she kicks both her legs in opposite directions as you try to maintain your grip.
