Everyone's over 18 in this story
Backstory:
Having had sex with my neighbor MILF twice in two weeks, I felt like the coolest kid in the neighborhood. She was hot, 42, had big boobs, and the hairiest pussy I had ever seen in my life. What's more is that she liked having sex with me since her husband wasn't fucking her. With my friend Kyle, her son, a hardcore gamer and being oblivious to what we were doing anytime I went over, I felt like I could explore Penny's body more and more each time I went over on the weekends.
New story:
As I sat in my room on Friday night, I was thinking about when I went over Penny's last weekend, she blew me in the kitchen, and then I fucked her upstairs and filled her up with my cum. I didn't take a shower for two days after that because her musky pussy smell was all over my dick and it turned me on so much. I jerked off twice a day on Sunday and Monday looking at the pictures that she gave me of her naked while sniffing her fresh dirty panties. Flipping through the pictures, it was clear that as a younger woman, her boobs were perkier, her nipples weren't as pointy, and she was a bit skinner.
Compared to how her boobs looked now, her areola had widened a lot, her nipples had gotten pointier and darker, plus her boobs had grown by at least two cup sizes. Having a kid changes a woman's body for the better and I'm glad that she had Kyle with a c-section, that kept her pussy nice and tight.
As was becoming my ritual, I stopped jerking off on Wednesday because I wanted to save up my cum for Penny when I saw her. On Saturday morning, I grabbed Penny's dirty panties that I kept in the ziploc bag under my mattress and stuffed them in pocket. I wanted to keep my promise of bringing her to bring back the dirty panties that I sniffed and jerked off to, that way I could swap her for a fresh pair.
I hopped on my bike and rode over around 11 AM, put my bike in the driveway, and then looked over to see that Penny was sitting outside at her pool in a bikini. She called out "hey Pete, come over here, I'm getting a little sun at the pool!". I smiled and walked over to see her, being careful not to come too close to hug her since I didn't want Kyle to see". She smirked when she realized what I was doing, then said "you can come over and give me a kiss on the lips, Kyle's out with his dad to do some back-to-school shopping and they won't be back for a while".
Smiling, I looked around and realized their entire backyard was surrounded by hedges, so nobody could see in. I walked over to Penny, bent over, and kissed her on the lips. Then, stepping back, I soaked in the sight of her in here bikini. It was about 85 degrees out, the sun was just getting high in the sky, and she was shimmering in beads of sweat. Her large boobs were being contained by a bikini top that was far too small, so the sides of her boobs were pouring out of it. Then, I looked down to her crotch to see her bushy pussy hairs coming out of the side of the bikini.
