It started out innocently enough. A couple of smiles, some lingering looks. We'd pass each other in the hallway and I'd look back, watching the sway of her hips, which I was sure she was exaggerating just for me. I'd be in the kitchen drinking some water, shirtless, and she'd stop at the entrance, examining me. If I caught her looking, she would just grin, stare a bit longer, and then walk away. And when she caught me looking at her ass, well, I smiled as well.
I'm talking about my mom, by the way, and about what happened during the summer. My sister and I were home from university, spending the summer at our parents' house. I don't know why, or what happened to my mom, to make her start treating me that way. I don't know what happened to me to make me reciprocate.
Ok, I know, I know. That's my mom. I shouldn't think about my mom in that way. As someone that I can be attracted to, sexually. But... it happened. Gradually, I started seeing her as the woman she was. Everything was gradual. Until it wasn't. Again, I don't know how this began.
All I know is things escalated. Quickly.
No, not the pecks on the cheek that became more frequent and lasted longer. Not the tight hugs where I could feel my mom's big breasts squashed onto my chest, my nose buried in her golden locks.
No, things escalated when my dad and my sister went away for a weekend. My uncle had invited them to go fishing at one of his properties, something neither mom nor I had ever enjoyed doing, so they left us alone at home and went on a trip. They left early on Saturday, the car packed with all the equipment they would need.
We had a pool, which we all frequently used, and the weather was just begging for me to take a swim. Which I did, wearing my loose shorts. A couple of laps, and some slightly acrobatic jumps, and then I was on a lounger, basking in the sun.
I heard a door open, and looked to the side, a hand shielding my eyes from the sun. Mom walked out of the door, and my jaw wanted to drop. For a woman in her early forties, she was damn fine, and I knew it. But now, as she walked towards the side of the pool, she wasn't just damn fine. She was damn hot.
No baggy clothes, no mom bikinis, no one-piece swimsuit. What my mom was wearing looked more like a bunch of tiny black strings struggling to hide what mattered the most. They joined in small triangles in three spots: her two nipples and her lady parts.
She strutted, her long legs making short work of the distance to the lounger next to me, where she lay down a towel.
"Enjoying the... weather, Matty?" she asked, her lips spreading into a big grin.
I gulped, called back to reality by her voice. "Sure am, Mom."
Her eyes roamed my body, taking in the sight of my broad chest and tight abs. I worked for them, and now someone... no, not just someone... my mom was enjoying my hard work.
"The house is empty without the other two, and I saw you doing some laps, so I thought I'd join you out here," she said, sitting down on the lounger. "You don't mind, do you?"
"Of course I don't," I replied. I didn't mind at all. Please join me here more often if that's what you'll be wearing, this is what I wanted to add, but... that was my mom. Not some random hot girl.
Mom turned around, her stomach facing down, and lay down. I sucked in a breath as I saw that her bikini really did not cover anything in the back. A tiny string held the top part together, and another seemingly disappeared into the glorious, round cheeks of her ass.
"It's scorching. Can you be a dear and put some sunscreen on your mother?" she asked, waving the bottle of sunscreen. "Pretty please?"
"S-sure," I scrambled to get up and grabbed the bottle.
Now standing next to her, I had a full view of her practically naked back, and I had to really hammer down that this was my mom. My mother. My beautiful, sexy, wearing-almost-nothing mom.
My hands shook as I moved to her legs, and my eyes were glued to them, trying not to look up. I knew what I'd see if I looked up, and I didn't know if I was ready.
I popped open the bottle and squeezed some sunscreen onto my mom's legs, then started spreading it around with my hands. I made sure to cover every inch of her smooth, soft legs, at least the parts I could get to from this angle.
Then my hands moved up, more and more, until I had no choice but to look at her ass. Again, it was a glorious, round ass. And that bikini truly did nothing to hide it, as it disappeared in between her cheeks. As I worked my hands up, she opened her legs a bit to let me have better access to the back of her thighs, and I swear I heard a small moan as my hands moved closer and closer to her butt.
"Hmm... you have such a good touch, Matty," she said. "Keep going, you're doing great."
I skipped past her ass cheeks, not brave enough to touch that part... yet. Getting onto the lounger, I straddled her legs with my knees on each side and covered her back with sunscreen. My hands moved in wide circles, from her lower back to the sides, then back again.
"Oh, I don't want a tan line, so let me just..." she reached back and untied the strings of her bikini top. "There we go."
I gulped again but continued my movements. I squeezed more sunscreen onto her back and moved upwards, covering it all. To reach her shoulders I had to move my legs up so that I was practically sitting on her upper legs. Which meant my shorts were dangerously close to her ass cheeks.
And if I knew one thing, it was that my cock was getting hard. For my mom. So there was no way I was letting my hips fall on top of her. She'd kill me... or... would she?
"Hmm, you forgot a spot," she said, wiggling her ass and making it get even closer to me. I almost jumped away but managed to hold myself in place. "You don't want me to get a sunburn, do you, Matty?"
"Right... of course not," I said, moving down. I faced her cheeks and breathed in. Then, my hands moved from her lower back to her ass.
I lost myself. My hands moved, squeezed, grabbed, and spread open her ass cheeks. My fingers melted into her flesh, and the string of her bikini finally showed itself as I continued to apply sunscreen, or, well, massage her ass cheeks.
At some point, I even squeezed out more sunscreen and continued my massage, mesmerized as I was by her ass. I could faintly hear moans, but I didn't register anything. All I was focused on was the feeling of her supple, soft cheeks.
Eventually, I let go, unsure why, and had to hastily move my cock in my shorts so the tent wasn't totally visible to my mom as she turned around. She had tied her bikini top back up, to my disappointment.
"All done back there, Mom," I said, before adding, "Do you want me to do the front of your legs as well?"
Ah, now I was volunteering to continue this. Not a wise choice, given my... condition, but I wasn't thinking straight anymore.
"Yes, I do, Matty," she replied.
I applied sunscreen to her legs and spread it around, while she did the same to her upper body. As I moved closer and closer to her crotch, again came the moans, and my heart beat faster and faster.
"Your dad would do this, normally, but he hasn't paid much attention to me lately," she said, breaking me out of the spell I was in.
I looked up at her, worry crossing in my face. "Is everything alright?"
"Oh, of course, nothing to worry about. Probably a passing thing," Mom said. "But it does leave a woman... wanting."
