I pressed her thighs and pushed them to the sides of the bathtub.
Mia's legs spread so wide that they almost formed a straight line for me to press against.
She even actively pressed her legs further apart, eager to open herself up more. I moved my waist, quickly and forcefully inserting my cock into her pussy.
Her pussy was submerged in the bathwater, and each rapid thrust of the cock created a splash of water.
The splashes fell down in succession like a large fountain, looking very beautiful.
I wondered how much of Mia's lustful water was mixed in this bathwater.
I thrust for about ten minutes, and Mia's buttocks unconsciously lifted up, her legs clamping together repeatedly despite my attempts to separate them. Finally, I lifted her legs to restrict their movement.
And sensing that Mia might be close to climax, I increased the speed and strength of thrusting, using all my strength to push my cock in, the flesh on the sides of her buttocks indented due to the tension.
Even my normally soft abdomen was now tense and rigid, feeling as though it could effortlessly press against an unopened bottle of soda.
Mia's abdomen began to spasm, and her toes, pressed against me, began to curl with force.
I continued to thrust a couple more times, and her climax arrived in a wave of intensity.
A gush of water erupted from her pussy, and I watched as her flushed, swollen lips quivered, still glistening with the remnants of her release.
Even my thighs were touched by her lustful fluids, feeling the rush of heat that mingled with the bathwater.
It felt as if the water itself was steaming with the intensity of our shared passion.
I pulled out my cock and rested for a moment, suppressing the strong urge to ejaculate, then turned Mia over, repositioning her.
Now Mia's waist dipped gracefully, her raised buttocks swaying enticingly towards me.
From top to bottom, I could see Mia's pussy, which I had stretched so much that it couldn't close.
I wiped her pussy with my hand, bringing out a wave of lustful water. I squeezed it in my palm, then rubbed it on her smooth buttocks.
Grasping my cock, I guided it back into her sensitive, freshly climaxed pussy. The moment I entered, her tightness squeezed me out of shape.
I quickly halted my thrusts, letting my cock rest inside her warm pussy, giving her time to adjust to my thick, hot length, and allowing myself to adapt to her heightened sensitivity.
When Mia's pussy stopped clenching around my cock so tightly, I began to move gently, slowly thrusting in and out, savoring the sensation.
After about five minutes of thrusting, her pussy began to relax slowly, and my cock also relaxed somewhat, with fewer veins visible.
The thrusting process became much easier, and it no longer felt like something was blocking the way.
After another ten minutes of thrusting, Mia began to respond to my thrusts, her buttocks occasionally pressing against me and even twisting a few times.
She was like a seductive little cat, extremely lascivious.
I raised my hand and slapped her buttocks, leaving five handprints instantly, making her let out extremely soul-stirring moans, evidence of her feeling very comfortable.
'Damn, could Mia be the submissive in an S&M relationship between us?' I wondered.
If we continue having sex for a long time, would her true nature be revealed?
I did enjoy having sex with women, but I didn't like those S&M games at all!
The thought of possibly causing physical harm to Mia disgusted me.
In my mind, if I liked breasts or a pussy, I would definitely cherish and enjoy them, rather than harm them to find solace.
Such behavior, in my opinion, was just a means for weak men to please themselves.
I changed from slapping Mia's buttocks to caressing them.
Her buttocks felt firm yet yielding in my hands as I forcefully thrust my cock into her pussy, occasionally squeezing them and finding satisfaction in the simple act.
Mia even pressed her buttocks against my hips, then reached a hand around to the back of my thigh, pushing me towards her pussy.
It seemed to allow me to penetrate deeper, and she could feel it more intensely.
She was begging for more, her body craving every inch of me. So, I indulged her desires, giving her exactly what she needed. I grabbed Mia's hand from behind and pulled it back as if pulling a rope on a horse's back.
Meanwhile, I pushed my waist forward against her pussy, slowing down the pace.
Each forceful thrust caused Mia to move forward with the inertia, as I paused for a couple of seconds to savor the tightness around my glans before pulling out and thrusting back again.
But with her hand already in mine, I tugged her back firmly each time she moved forward.
This meant that with each insertion, my cock experienced a double thrust, with my glans hitting her sensitive spot and creating a strong suction for a second, stirring an intense urge to release all my semen. But this would give me a feeling of competing with Mia. Who would bring the other to climax first?
Once this competitive mentality arose, there was a desire for victory, and my thrusting force increased even more.
I even felt like I would crush Mia's sensitive spot, and my glans would firmly penetrate her uterus.
Every time I hit that hard and solid wall of flesh, I would try my best to push my cock a little further into the pussy.
"Easy... easy..." she gasped. "I can't take it... Slow down... slow down... Be gentle... please... I beg you..."
Mia's pleading voice was very satisfying to me.
