By manual combat

“I want you naked”. Advancing forward you slowly undress Esther.

Within mere seconds she is naked. You study her standing next to you. Her athletic but rounded body, her large, creamy breasts standing proud before her, her rock-hard nipples pointing at you. Her face looks excited and gorgeous, no sign of weariness. Behind her, her ass was pointed out, presenting a delectable sight, each round cheek highlighted behind her.

"Are you ready?"

Her hand moves to grab your cock but all she does is holds you between her thumb and other fingers, slowly squeezing and pulling you in just the right ways. You can't believe how amazing it feels despite the fact that she is barely moving her hand.

You hand moves to her smooth mound. There your fingers play with her for a few minutes, teasing the lips, then her clit, occasionally forcing her to tense all her leg muscles not to react to your manipulations.

Esther goes to focusing solely on the base. She firmly tugs and jerks you there, and it doesn't take long to figure out that this is going to be it. She is unrelenting; the more she does it, the more you feel an orgasm building up behind your cock. Jesus, how is she so good at this… you try to hold it back, but it is pointless.

You sense an involuntary contraction of her lower abs. On your side your hips involuntarily pump into her had. You manage, after a tough mental struggle, to halt the pleasure signals. Her ab contraction stops too, so you switch to a new technique on another erogenous zones. Thankfully her ab contraction just got tighter. You are happy to conclude that her sex is fully wet. On the other hand, you are leaking enough pre-cum to lubricate her ministrations.

"Come on baby. Blow it. Lose control. Cum for me. Shoot all the cum in those tight balls. I can feel your cock getting thicker. Shoot that hot stuff on my pussy or on my tits."

"You first Esther!"

You are now both pumping your hips into eachother's hands. Her whole body contracts and she drops her sweat soaked forehead on your shoulder. Grunting and gritting your teeth you resume your grip on her sex giving her your best. Meanwhile, you feel like you are enduring an experience you never want to end.

Both of you moaning you both of you seeking stubbornly for some weak point in order to finish your rival. Your bodies rub into each other harder and harder. Your bodies glow filled with raw arousal, your sexes going incandescent. Esther is somewhat surprised as you now prove capable of resisting some of her more devastating techniques, showing off an incredible endurance, and even retaliating, trading stroke by stroke, guided by your experience.

Esther's arm is probably suffering form fatigue, so she effectively switches to a butterfly technique, on which you increase your breathing. You mimic her movement by catching her clit between your fingertips which you frantically vibrate against the edge of the pubic bone. As if on cue, you release eachother from your sex hold. It's as if a time out is set between rounds of a boxing match.
