At first, he just tried not to be effected mentally or emotionally by her attacks to his crotch.
Bending over to try dodging would not help, as she would just use another access point. Crouching to avoid her attacks proved useless, since she would lie down and attack him. Denying her usage of one body part to attack him did not work, as she had other ways. Emitting weird noises to distract her also did not have success, as she found them funny.
Folding [first either one of, then both of] her arms behind her back ended being pointless, since not only could she still use her head, boobs, chest, hips, waist, crotch, ass, legs, knees, and feet to attack his crotch, but whenever he folded her arm[s] behind her back, ... she would either twist her body slowly, moving her chest & breasts into a rather nice bounce, jumble, shake, wag, and nod, or she would cleverly grasp her hands together, smile with arousal and excitement, and pull her arms nicely back as far as she could, effectively causing her to arch her back, which caused her to thrust her chest forward, thereby enhancing, enlarging, inflating, pumping, and otherwise simply bringing more [...as if they needed] focus right for her enchanting, erotic, sexy, kinky, & naughty breasts, which seemed to shake, jostle, roll, freeze, stiffen, and almost smile every time they faced her opponent's pecs, chest, ass, biceps, or crotch. Even if he positioned himself behind his sexy opponent and grabbed her arms behind her so she simply couldn't move them, this didn't work for several reasons.
First off, he would watch her squirm, pretending to struggle, acting like he was much stronger, mightier, tougher, & just smarter harder than her. This by itself fed his ego. Hearing her play the damsel in distress, using all the cliches, always made him horny. Things like "Oh, you're so strong"; "How can I ever escape?", "Such a firm grip here!", "You've got me completely helpless!", "Whatever can I do now?", "Those muscles are simply ultra large, strong, hard, and bulgy"; Let me go, you nrawny behemoth".; "Can't anybody rescue me here?"; "When can a hero come to save me?"; and "My curvy, sexy, and lithe form will never be a match for your muscular, mighty, magnificent, strong, shapely, sculpted, powerful, and rippling body!"

Each of these phrases and so many others always managed to lower his defenses by increasing his erotica, sensuality, titillation, hardness, erection, excitement, and arousal.
She knew that feeding a guy's ego always managed to lower his shields and defenses.
Second off, every time that she would squirm, she would shake all around, left and right, forward and backward, in circles, and other ways. When she did this, she would move her back with a nice arch. Every arching of her back always resulted in her thrusting her chest forward quite prudly and efficiently, enlathereby enlarging, inflating, and enhancing her abs, breasts, cleavage, and shouldres, and waist.
Third off, every movement of her arms against his chest just actually slightly tickled him, making him laugh like a little boy and this lowered his guard even more.
Fourth off, every movement of her head made her hair sway left and right, and also waving quite nicely just directly in front of his happy face. Every time her long hair would move, some of her hair would either tickle his smiling face, excite his glad nose, fall on his head [whenever she cutely nodded and shook her head], or slightly get into his open mouth. Each of these moves just either made him grin, laugh, sneeze, shake his head, or even become slghtly more erect.

Fifth off, every time she would shake, jostle, rumble, tremble, squirm, or otherwise move while she stood there in front of him as he held her securely with a standing arm-lock, ... whatever action she did, whatever pose she took, & whatever way she moved her body, ... she would always manage to stay with her ass pressed up naughtily, muscularly, strongly, kinkily,sexually, mightily, cleverly, and even carnally against his already excited, happy, aroused,hard,, and erect crotch. This meat that whenever she shook or otherwise moved her body, she rubbed, massahed, kneaded, stroked, pushed, and moved every bit of his crotch with her sexy, erotic, titillating, and playful ass. This caused quite an unavoidable enhancement in the erection, hardness, excitement, sensiticity, and gladness of his crotch.

He may not have known this, but each time her ass rubbed around, against, across, or on his increasingly happy crotch, she also became hornier, more aroused, excited, & titillated.
Gripping either one or both of her legs either simultaneously or one at a time also didn't prove to be useful, as he would have to do that either right in front of her or maybe right directly behind her. Either way, this still left her with complete use of her head, mouth, breasts, cleavage, chest. abs, tummy, arms, elbows, hands, hips, waist, crotch, and ass. Although he thought about grabbing her by each leg and either spreading her legs wide until her crotch either snapped or bended, or doing the old wrestling move of just looking down at his opponent as they beg him not to take the next step, and then either easily stomping, stamping, stepping, punching, elbow-dropping, pounding, knee-dropping, tickling, punting, grabbing, mashing, pulling, pumping, or otherwise attacking her crotch, breasts, or ass, but he did not want to attack any woman in such targets.
