Convinces her not to cover up

"Nonsense, you don't need a shirt," he said confidently with his eyes still locked on Carrie's chest. Carrie crossed her arms, doing what little she could to cover her large breasts from being on display.

"Oh come on, it wouldn't be decent for me to strut about the house with my, well as you called them, big fuckin tits hanging out around my boyfriend's grandfather!"

Your grandfather just smirked at her words, turning his attention over to you.

"It's perfectly fine, right kiddo? Nothing wrong with a faithful little girlfriend walking around without a shirt and being comfortable. You're not worried about me stealing away your woman or somethin are you?" he asked. Unfortunately there wasn't a great way for you to respond. You could tell him you originally wanted Carrie to get flirty and dirty with him anyway, but who knows how he'd react. Plus you weren't worried about him fully stealing her away or anything like that, so why not encourage this?

"No, of course not Grandpa," you eventually said back. You noticed your grandfather had already gone back to gawking at your girlfriend's chest, and as soon as the words left your mouth your grandfather's gaze went from Carrie's chest to her eyes.

"See, he's fine with it which means you should listen to me and stay like that. Let those huge fuckers breathe so ole gramps can enjoy the view," he said. It was still strange to hear how perverted he could be at times, not that Carrie seemed to mind. She shot a fleeting glance over to you, then lowered her arms and smiled at your grandfather.

"Alright, I guess I can stay like this, since it's not that big of a deal to your grandson."

With that, Carrie grabbed one of the beers she had brought in and went to the couch, nestling herself next to the horny old man. Your grandfather wrapped his arm around your girlfriend and pulled her snug against him, looking down at her chest.

"In fact, at home you shouldn't ever wear a shirt. You're too fuckin hot to hide that body under clothes and I love seeing a sexy little thing strutting about."

"Okay, it'll be nice to just be comfortable at home and not wear as much!" Carrie said, genuinely happy about the idea.

"Good girl. Give Grandpa another kiss," he said, and Carrie dutifully craned up to plant her lips on your grandfather's. This time there was no hesitation and Carrie welcomed your grandfather's tongue as they kissed right in front of you. Carrie was immediately enjoying herself, occasional moans slipping out as they made out like horny teenagers.
