Why not? You've got nothing better to do

"Sure Karen, I can stick around for a bit. I don't really have much planned for today. Besides, I can think of worse things to do than help my beautiful neighbor get high." you say laughing.

Smiling at your cheesy compliment, Karen takes the first hit from her vape, then offers it to you. "I'm not the only one doing this" she tells you. "You have to do it too."

Not one to argue, you take a hit with her. Once you've had yours, you place the vape on the coffee table, telling her it's best to just take one hit to start with to see how it affects her and experiment with what works best for her over the next few weeks. It doesn't take long to see that one hit might be more than enough for Karen. She's soon lying back, feet on the coffee table, obviously much more relaxed, and becoming much more talkative. You're enjoying her company and don't move to stop her when you see her reach for the vape for a second hit, or decline a second hit yourself when she passes it to you. Within five minutes, she's turned herself on the couch to face you and has placed her legs on your lap, her inhibitions gone.

"Damn! This is some good shit!" she says, giggling. "I forgot how much I enjoyed this!" She sighs before speaking up again "Ohhh, don't get old David!" she tells you, then starts recalling stories from her college years. "God, I was so hot back then! My tits stood up straight, my stomach was flat, and my ass was so tight! I didn't even have to work for it! Now I have to work out 5 days a week just so I don't lose what I've got left! You would have liked me David" she says smiling at you. "Lots of boys liked me." The lids of her eyes have become heavy and a permanent grin is on her lips as she thinks about her past. "Do you know how much sex I had back then?!" she asks you rhetorically. "Fuck! I used to love sex! I couldn't get enough cock back then David. Jeez, I was a slut! But then I got married, pregnant, got a job, responsibilities.... I just lost interest. How does that happen?"

Unsure if you're supposed to respond, you just shake your head and shrug your shoulders before a feeling of comprehension crosses your mind as some of your own concerns about your current relationship come to the forefront of your mind. "Maybe you lost interest because you were bored" you tell her, resting your hand on her calf. "Having sex with the same person, week after week, year after year. Knowing what was going to come next, how long it would last. Maybe you missed the feeling of being wanted by another person. The mystery of what they would do to you once they got you naked." Your hand begins to slide up and down her smooth calf, soothing her and relaxing her further. "But I guess it's possible you just didn't like sex as much as you thought you did, too" you say, goading her.

"You know something? I think you're right! I always loved the excitement of something new; new guys, new positions, the unknown of what would happen. I remember one time I met these twins at a bar; god they were hot; and I spent the night doing shots with them and flirting like crazy. The only problem was I couldn't keep who was who straight in my head and kept calling them by the wrong name. It started to become a game for us. First they wanted me to do a shot if I got their name wrong, but I told them I'd blow them instead if I guessed it wrong. Of course I got it wrong, but thinking about both their cocks in my mouth got me so wet that I purposely called them any other name I could think of the rest of the night." With that last sentence, she starts laughing out loud. "Oh my god, I hadn't thought about that in so long! I'd say something like 'Bob, I mean Billy, I mean Tim, I mean Ricky...oh fuck! I guess you'll have to fuck me in the ass while your brother fucks my pussy now!'" Laughing out loud again she says "And I never learned their real names!"

You feel your dick begin to stiffen as Karen recounts her story to you and begin to run your hand past her knee, up to her thigh. "So what happened?" you ask her. "Did you go through with it? Or is this where you tell me you got too drunk and passed out?"

"Oh, I went through with it all right. They filled up all my holes that night. I don't think I've ever cum like that before, or since then. Shit, I'm getting wet just thinking about it!"

Not willing to take her word for it, you slide your hand up under her dress and between her legs against the dampness of her cotton panties. "Wow, you weren't lying, you really are wet!"

"David! What are you doing?! You shouldn't be doing that!" she says, starting to scoot away from you. "It's my fault, I shouldn't have been talking like that to you. I gave you the wrong idea. I guess we know I can't handle this weed." she blushes, pushing the dress down between her legs.

She seems flustered and you're unsure what to do next. Do you apologize and leave, or do you push your luck and see how far you can get with her?
