Lavinia braced herself on all fours, putting strength into her hands and knees so she wouldn't collapse under the impending creampie…
Smack smack smack smack! The rapid, successive sounds of hips meeting flesh echoed. Her buttocks rippled in waves. Her abundant, soft breasts bounced heavily in every direction.
The sensation from her nipples, teased by the air with each bounce, sent fresh waves of pleasure coursing through her.
And the moment his cockhead thrust in so deep it seemed to embed itself into her thoroughly loosened and prodded cervix, Lavinia climaxed.
"I-I'm cumming! Ah, AHHHHHAHHHAHHHH────!"
As she climaxed, her inner walls clenched down tightly around him. That stimulation triggered Renya's own release, his cock pulsing with a wet sound as he ejaculated.
Splurt Splurt!!!
"Aah, it's hot! So hot! I-It's coming! It's filling me! I-I'm cumming agaiiin!"
Toyed with by the semen being shot directly into her uterine cavity, Lavinia experienced a climax within a climax, a greater peak overtaking the first.
'I-It's incredible! Thump, thump! It's thrashing around inside me! Ooh, it's heavy! My belly… my womb feels so heavy with Leo-kun's semen!'
The rhythmic pulsing of his still-thrusting cock was visible from the shape rising on Lavinia's lower belly. With each throb, splurt, he released more seed inside her cunt, and she felt her womb grow heavier and heavier.
Soon, perhaps overwhelmed, her belly slackened slightly before beginning to swell little by little. It was becoming a soft, bloated belly from the massive amount of semen.
Filled to the brim—perhaps even reaching her fallopian tubes—Lavinia looked like a woman several months pregnant.
"Hah, hah… I-incredible… It's like I've gotten pregnant with Leo-kun's baby… Ngh, haaan…"
Ever since the first day Renya came inside her womb, Lavinia had become acutely aware of its exact location within her.
As a reincarnated devil with low fertility, had they not used contraceptive magic, she would have been pregnant long ago.
"Lavinia, you did well."
"Muu… Leo-kun, you were kind of mean today. I feel like I did so many… terribly embarrassing things, you know?"
Having her head stroked by Renya felt good, but that aside, Lavinia felt she had been teased enough not to let it slide.
"Yeah, you were cute."
"Honestly… This is how Leo-kun trains me, isn't it? My body… It's become solely for Leo-kun's use now."
Despite her words, Lavinia looked happy. It showed just how completely she had yielded to Renya, both mind and body.
"…Ah, sorry about that. Well, looks like we still have plenty of time before nightfall…"
"Y-you have plans later today, don't you?"
"Yeah. So I'm gonna take a bath now and then go make an appearance. What about you, Lavinia?"
"Nn… slurp… I'll go with you, so… let's bathe… Ah, but, kiss, no mischief, okay?"
"Yeah, got it."
They remained connected for a while longer. Delighted by the sudden kiss, Lavinia, seeing they were alone, made no attempt to hide her voluptuous figure as she swayed out of bed and linked arms with Renya.
"We'll continue tonight."
"Aau… Please be gentle with me, okay?"
As Renya whispered in her ear while kneading and gripping her firm, voluptuous ass, Lavinia felt a shiver run through her from a primal, feminine instinct.
Begging for his favor, she hugged his arm tightly between her full breasts, pressing herself against him.
Unbeknownst to her, this only served to stoke the flames of Renya's masculine instinct even higher.
And so, the two headed straight to the bathroom in the room. They washed away the remnants of last night's and today's passion, attended to their grooming like washing their faces, then returned to the room once to change into casual clothes before finally leaving the room behind.
Later…
Having finished preparations to go out, Renya and Lavinia were visiting the "Gray Wizards," one of the magical associations they belonged to in Italy, in the slightly late morning air.
Renya walked through the corridors of the facility, where many mages and sorcerers gathered, arm in arm with Lavinia.
When the two of them, famous even within the association, walked together, they naturally drew attention, but those affiliated with the association were already aware of their relationship. After a brief glance, they would return to their own research or studies; it was mostly only newcomers who would still cast surprised or envious looks their way.
Ignoring such curious stares, Renya and Lavinia arrived at their destination.
Renya knocked on the imposing plaster door, and a light voice responded, "Come in~."
Renya said, "Excuse me," and opened the door, with Lavinia following. Inside the room with its calm interior, the man sitting at the desk with his back to the window welcomed them with a smile.
"Ah, there you both are. Glad you could come."
"Sorry, we're a little late, Dad."
"Sorry to keep you waiting, President Mephisto,"
Renya and Lavinia responded thus to the man facing them across the desk.
The man called Mephisto was Mephisto Pheles…
