Feeling his cock still hard and thick even after cumming, the MILF asked, her expression dreamy.
Gasping at the allure of Venelana, languidly pushing back her hair, Kazuki began to move his hips once more…
Gush! Gush! Gush---!!
"Aaahhh!!... Nngh, again, so much is coming out..."
Venelana, positioned from behind, received her third vaginal ejaculation of the day. Her womb was already overflowing; the semen that couldn't be contained spilled out, forming a white pool on the sheets beneath her.
Yet, Kazuki's cock still stood proudly erect, demanding more of Venelana's body.
"Haa... haa... Honestly, Kazuki-kun, you're still not satisfied, are you? In that case... how about trying this?"
With his shaft still buried inside her, Venelana spread her own buttocks with her hands, exposing her reddish-brown anal opening right before Kazuki's eyes. Instantly, a distinct, musky odor assailed his nostrils.
Perhaps not fully removed, a few flaxen pubic hairs remained around Venelana's anus, a sight that only served to further excite Kazuki.
"You like putting your fingers and tongue in assholes, don't you, Kazuki-kun? So I thought you might be interested in this... Fufu, that look on your face tells me I'm right."
If asked whether he was interested, the answer was a definite yes. Venelana's proposal was a godsend for Kazuki, and Venelana herself felt a dark thrill at the thought of being his first for this as well.
"Really, you should use an enema beforehand to clean it properly, and stretch the hole out first, but since I came prepared today, it should be fine to just put it in."
Kazuki withdrew his dick from Venelana's pussy, and using the attached semen and her juices as lubricant, he smeared it all over her anal cleft. Pressing the head of his cock against her twitching, contracting anus, he slowly pushed inside.
"Nnghhh!? Uuu... ngh, nuaaahh!!"
Kazuki's cock excavated her anus, a passage even tighter than her vagina. Although Venelana's hole had been prepared, it still tightly gripped his shaft as it welcomed him deeper inside.
"Hfffuhn!... I-It's in...! Ah, this is no good... something this thick, ngh, it's so tight..."
Despite the preparation, it was clearly still tight; Venelana cried out in a mixture of pleasure and strain. Her anus, being used for a purpose other than its intended one, seemed to protest, clenching fiercely around Kazuki's invading cock.
Kazuki held still with his shaft buried inside, observing Venelana's state. Judging that her breathing had calmed, he began to slowly withdraw.
"Nnnn!? Nghiiieeaaaahhhh!! "
The moment Kazuki started pulling out, Venelana let out a scream. The sensation of his cock being withdrawn triggered a pleasure in Venelana reminiscent of the feeling of defecation.
The act of excretion is said to be one of the first pleasures a person learns. The feeling of the thick cock being pulled out during anal sex gave Venelana a pleasure similar to passing a large stool.
And then,
"Nnnn!? I-It's coming back in again!!"
As he pushed back inside, Venelana cried out in strained pleasure,
"Haaahn! Having the cock pulled out feels sooo gooood!! "
And as he withdrew, she shrieked in ecstasy.
The pain of insertion and the pleasure of withdrawal assaulted Venelana in waves. As the rhythm of his hips gradually increased, Venelana lost the ability to distinguish between the discomfort and the intense sensation.
Eventually, as the boundaries blurred, even the pain transformed into pure pleasure for her.
"Ahii! Nghoh! My ass, my asshole feels so good! Aaaahn, with Kazuki-kun's cock, Venelana's asshole has become a pussy!! "
Completely dominated by pleasure, the MILF screamed, her beautiful face streaked with sweat, tears, and snot. In this crazed state, her usual ladylike elegance was nowhere to be seen.
Kazuki, for his part, was also experiencing an unusual excitement from his first anal sex. Though initially bewildered by the sensation of the anus, so different from a vagina, and the grip of the anal sphincter, seeing Venelana's enjoyment reassured him that this was right, and he continued to move his hips.
Watching Venelana's reactions, Kazuki savored the novel feeling of her back entrance. He varied his pace, thrusting in quickly and withdrawing slowly, and played with her plentiful buttocks, caressing them. Soon, the tightening of her anus signaled that the end was approaching.
"Guhh... Lady Venelana, I'm about to..."
"Nnghaaaahh! C-cum inside me! Fill Venelana's anal cunt with Kazuki-kun's semen!!"
Blop, blop, the anus made lewd sounds as it swallowed his cock. Burning the sight into his memory, Kazuki released his final load of the day.
Splurt! Gush! Spluurtt---!!
"Ohohohohーーーnnnnn!! "
With the explosive ejaculation, Venelana's anal clamped down spasmically. Overwhelmed by the heat of the surging white torrent flooding her depths, Venelana's face went lax with ecstasy as she collapsed onto the bed.
Having emptied all his desire into her rectum, Kazuki slowly withdrew his cock.
And then...
Pbbbtth~, fffth, pshhh!
"Nnnn... aah... "
He watched, dazed, as the white, viscous fluid spurted from Venelana's asshole with vulgar sounds…
"Mmmmm, satisfied! Fufu, that was truly wonderful, Kazuki-kun. "
"Haa..."
Having been filled in both front and back, Venelana was completely satisfied. Kazuki, on the other hand, seemed somewhat subdued. It was unthinkable that he wasn't satisfied after all they'd done, so he was probably feeling guilty towards her husband or Rias.
Well, it wouldn't really matter even if they found out, but she supposed she should drive the point home just in case.
"Kazuki-kun? Don't you dare let guilt get the better of you and talk to Rias about this. What happened tonight is a secret between the two of us. Understood?"
When Venelana pressed him, Kazuki nodded obediently.
'Good boy.'
Venelana smiled as she gathered her scattered clothes from the floor beside the bed. Then, she stroked the cheek of the still-lying Kazuki and pressed her lips lightly to his.
"Well then... see you again soon, Kazuki-kun."
"Huh?... Eh!?"
Seeing the shock on Kazuki's face, Venelana's smile deepened. It was too bad for Rias, but she'd finally found such a perfect cock. 'There is no harm in borrowing it for a bit of fun every now and then, right?'
Leaving the stunned Kazuki behind, Venelana Gremory mused about when their next encounter might be as she left the room with a light step.
