The room was a scene of pure depravity. The succubus MILF lay on the floor, her skin covered in red handprints and sweat. Her eyes were fixed in a heart-shaped gaze, her tongue lolling out as she panted.
Alex was still behind her, buried deep inside her, while his hands squeezed and pulled at her heavy breasts.
Eri's mind was a blur. She had "died" several times already from the sheer intensity of the orgasms. When Alex finally reached his limit again, he flooded her womb with hot essence.
"EIIIIII—!!!!"
[Hearts +1]
Alex noted that he gained hearts from demons just like humans.
"Madam, this is just the beginning," Alex whispered, pressing his chest against her back. He began a new round of frantic thrusting.
Eri felt like a small boat tossed in a storm. She couldn't believe a human boy was this strong.
Squelch, squelch, squelch!
After countless orgasms, the room finally went quiet. Eri lay in a puddle of her own fluids and Alex's cum. Her stomach was slightly distended from the sheer volume of his "donations." She was utterly satisfied.
"Madam, aren't you going to get up?" Alex sat next to her, playing with her milk-scented nipples. He leaned down and took one into his mouth.
"Alex-kun..." Eri blushed. "Why do I have... milk? Is that your power too?"
She found she couldn't push him away. Her body was now addicted to him. Her tail flicked rhythmically between her legs.
"You're quite the slut, Mrs. Morita," Alex teased. "A normal girl would have passed out long ago, but you're still wet."
"Alex-kun..."
"I have to go back to the twins now," Alex said, letting her go. "But next time I summon you, I'll satisfy you even more."
Eri wanted to say no—she had a family!—but the memory of the pleasure made it impossible. "Will you... summon me again?"
"Of course. And don't worry about your husband. I won't break your family, but I also won't let another man touch what belongs to me. You understand, right?"
"Eh? What do you mean 'belongs to you'?"
"Look at your stomach, Madam."
Eri looked down. Her eyes widened. There, on her lower abdomen, was a glowing, pink heart-shaped mark.
"A SLUT CREST?!!!"
"I'm the succubus! Why am I the one who got marked?!!!"
