Yes, take in the ass.

“Oh god, okay Rick, I guess.” Mindy cringed in horror.

“Thank you Mindy, you're the best granddaughter ever. Now get on all fours.” Rick smiled.

“What?” Mindy asked confused.

“Have you ever put anything in your but Mindy?” Rick asked with a frown.

“No.” Mindy gasped.

“Well, it's kind of big Mindy, so you're going to need help getting it up there, right?” Rick pointed out.

“Oh, oh god, I guess.” Mindy lamented, groaning in displeasure, the young woman got on all fours and hiked her skirt over her lush derriere.

“Damn Mindy, you ever thought about getting better panties?” Rick asked, getting behind her and pulling them down exposing her round cheeks.

“What's wrong with my panties?” She asked annoyed, as he was the second person to insult them.

“They're ugly.” Rick said bluntly, gently pushing the seed into her virgin ass.

“Wow, the seed feels so small.” Mindy gasped in surprise.

“Seed, geez Mindy, this is just my finger.” Rick replied sardonically.

“Rick!” Mindy screamed in panic.

“Mindy, don't tighten up, okay, you can't take the seed in one go. I'm stretching your ass a little so it doesn't hurt.” Rick scolded her.

“Oh.” Mindy groaned trying to digest the fact that her grandfather was fingering her ass. After a few plunges, she heard him squirt something and stuck a second finger. “What's that?” She asked curious.

“Lube.” Rick said gently stretching her rectum.

“Oh.” Mindy moaned, as Rick withdrew.

Another squirt, and her grandfather took her hips with both hands and guided his fingers into her again. He must have added a third finger, because she was being stretched to the limit. If it wasn't for the lube, it likely would have hurt. Rick began pistoning his fingers in and out of her, his hips slapping against her firm derriere, as he worked to get her to open up.

Mindy couldn't stop herself from moaning softly, as Rick finger banged her tight ass, with gusto. She wasn't sure why he was becoming so fervent, but she was feeling to much pleasure to stop him, and to much shame to say anything. Finally he tightened his grip and slammed his fingers to the root, with a grunt, as a warm sensation filled her bowls. Mindy shook in pleasure, as she hit her peak, biting her hand to stifle any noise she might make.

A moment later he withdrew his fingers, and taking one of his hands from her hips, he slid a large ridged object into her ass. She could tell it wasn't his fingers, because though it was about the same size, the ridges rippled against her walls, as it sunk all the way in.

“Heh, your first butt plug.” Rick chuckled standing up.

“What?” Mindy asked confused.

“Nothing, come on, let's <burp> let's go.”
