Ben pulled up to his childhood home, a quaint two-story house that held a thousand memories. He hadn't been there in years, not since his little sister Lily had moved out to start her own life. But now, he found himself pulling into the driveway, unannounced and eager to see his sister.
He walked up to the front door, not bothering to knock, and swung it open. What he saw inside, however, was not what he was expecting.
Lily was lounging on the couch, one leg thrown over the arm, a mysterious bulge in her pants. Ben tried to ignore it, but Lily's playful insult cut through the air.
"Ben, you're home! And here I thought you were too dense to notice a damn pole in my pants," she said, a smirk on her face.
Ben's eyes widened as Lily slowly pulled down her pants, revealing a fat, meaty horse cock. He blinked, unsure of what he was seeing.
"It's just a little something I've been growing. No need to be scared, big bro," Lily reassured him, a twinkle in her eye.
Their mother, Denise, walked into the room, her eyes going wide as she saw the commotion.
"Lily, what have I told you about flashing your little brother like that?" she scolded, but there was no heat behind her words.
Lily, undeterred, challenged Ben. "Come on, be a man and feel it for yourself."
Ben hesitated, but eventually reached out, touching the horse cock. He was surprised by the warmth and firmness. Lily moaned, a look of pleasure on her face.
"See, it's not so bad, is it?" she asked.
Denise watched, her own arousal growing. "Go on, don't be shy. It's not every day you get to touch a horse cock."
Lily took charge, ordering Ben to get on his hands and knees. She positioned herself behind him, teasing his asshole with the tip of her horse cock.
Ben asked what she was doing, and Lily responded with a playful insult. "What does it look like, dummy? I'm going to fuck your tight little asshole."
Denise encouraged her, "go ahead, fuck your brother's asshole. He can take it."
With one swift thrust, Lily impaled Ben's asshole with her horse cock. Ben cried out in pain, but Lily reassured him. "It'll feel good soon, I promise."
Lily started to fuck Ben's asshole hard and deep, each thrust causing Ben to moan in pleasure. Denise watched, touching herself as she encouraged Lily to "cum inside your brother. Fill him up."
Lily, unable to hold back, came inside Ben's asshole, filling him up with her seed. She pulled out, and then turned her attention to Denise, fucking her mother's pussy and cumming inside her, impregnating Denise.
The chapter ends with the three of them, exhausted and satisfied, lying on the couch. Ben thought to himself, "this is one hell of a surprise visit."
