No resistance

Without turning her whole body, Brenda rotates her head, looking over her shoulder and just catching a glimpse of you in the corner of her vision. Straightening her legs, she bends over again, and the short sundress rides up high on her bare ass, confirming your suspicion that she is not wearing any panties. "You mean this ass?" she asks, her asscheeks and pussy clearly exposed to you. Before you can react, she straightens up again, and with exaggerated motions, straightens out her dress. Not turning to look at you, she steps away from you, and up into the back of the half-emptied moving truck. You quickly follow.

Still not facing you, Brenda walks over to the side of the truck. Laying her face sideways she presses her cheek against the metal wall, and reaches up above her with both hands and grips a canvas strap bolted to the wall near the ceiling. She spreads her legs slightly, her feet about twelve inches from the wall, and placed just slightly further than shoulder length apart. Her back arches gracefully as she slumps into the wall, sticking her ass out slightly as she locks her knees.

Following her lead, you step up to her silently, and push her dress up to her waist, letting it drape around the curves of the tops of her hips. Brenda's ass is perfect and round, full and with a little meat to it, but still firm and smooth. Her ass is a tight little puckering, and you know that no matter how hard you are, you can't just **** your way in. You stick your left thumb into your mouth, coating it with saliva, then all the fingers on your right hand. You gently wrap your hand around her left ass cheek, but she thrusts her pelvis back against you slightly, encouraging you to get on with it, already. Emboldened, you press your thumb against her anus. You feel her muscles tighten quickly underneath you, then all of a sudden loosen, and your thumb slips right into her ass. As you push and rotate your thumb inside her, you pull out your cock with your right hand, then dip your fingers into her slick pussy and bring back out some sticky juice to lubricate your cock with. While her asscheeks are firm, her sphincter seems to melt away softly under your exploring thumb, her muscles already mentally loosened in a manner that suggests firm inner control and perhaps considerable experience.

No matter. Removing your thumb, you line your pussy-juice-sticky cock up in its place, and slide inside Brenda's ass. Her eyelids flutter slightly, but her ass muscles (and seemingly every other muscle in her body besides her still-arched back) remains loose as your cock sinks balls-deep inside of her. Grabbing her asscheeks now with both hands, you pull yourself back, then spread her cheeks wide as you shove yourself back in. Despite the relative ease of entry, her ass is tight, and you have to really put your hips into it to plunge back inside her. Once fully inserted, it is surprisingly hot inside, her anus gripping you like a glove left out in the sun. You fuck her at a medium pace, pulling out and pushing in, as she sways slightly, hanging from the canvas straps. her upper torso getting smushed against the wall, then released in time with your pumping.

Brenda's eyes are closed, and she seems to be mouthing some sequence of words to herself, though no noise comes out.
