Sandra’s hands rested lightly on my chest, not pushing me away as she stared at my massive erection pressed against her. The mature woman was clearly conflicted, her motherly instincts fighting against the undeniable arousal I causing her.

Her soft, voluptuous body felt incredible against mine, and I could feel her warmth and the way her belly moved with her quickened breathing.

I started moving my hips, rubbing my cock on her belly, chasing my orgasm as the thick, hard shaft slid against her soft, warm skin, leaving a trail of precum.

"Maybe I don’t need any pill, Grandma. Maybe I’ll do this instead," I said as I held her hips and kept rubbing my cock on her, grinding the throbbing length against her soft belly with slow, deliberate movements.

"No, Alex... stop it. It’s wrong," Sandra said. She put her hands up on my cheeks, caring for me like a worried grandmother. "Come with me, you should take the pill."

Sandra started moving and pulled me by my hand toward her bedroom. The way her ass swayed in her trousers was making my blood boil with lust, the soft, thick cheeks moving hypnotically with every step as I followed her.

Soon we reached her bedroom. She opened the door and led us inside, the room feeling cozy and intimate with soft lighting and a large bed in the center.

Sandra’s mature, voluptuous body moved ahead of me, her wide hips and plump ass still drawing my eyes as she walked toward a small table where she kept her medicines.

Sandra was bent at the table searching for medicine.

"Wait, I can’t find those pills," Sandra said, her voice a little frustrated as she rummaged through the drawer.

I looked at her bed, and her bedsheet was a mess. I could see some wet stains on it, clearly from recent activity.

"Your bed is a mess, Grandma," I said, my voice low as I stared at the disheveled sheets.

"Oh, sorry about that," Sandra said, moving quickly, embarrassed about something. She climbed onto her bed from the edge, trying to smooth out the bedsheet. She was on all fours, her ass close to the edge as she worked with her hands to straighten the bedsheet.

That sight was too much for me. I moved behind her quickly and let my cock rest against her ass, holding her hips firmly.

"Ahh, fuck... Grandma, please stay like this," I groaned as my cock found heaven between her ass cheeks, the thick, hard shaft nestling perfectly in the soft, plump valley as she bent over like that.

The mature woman froze on all fours, her thick ass pushed out toward me as my heavy cock pressed against her. Her soft, round cheeks felt incredible against my throbbing length, the fabric of her trousers the only thing separating us.

Sandra’s breathing quickened, her body trembling slightly as she felt the heat and size of my erection against her. The position, her on all fours on the bed, me standing behind her with my cock resting between her ass cheeks, was incredibly filthy and arousing.

I held her wide hips tighter, savoring the moment as the lonely GILF remained bent over, clearly conflicted but not pulling away.

I started moving my hips, rubbing my cock against her holes over the trousers, the thick, hard shaft sliding between her plump ass cheeks as I dry-humped her from behind.

"No, Alex... ahh," Sandra moaned as she felt my cock touch her holes over the fabric, her body trembling slightly as the heat and pressure made her voice break.

"Please stay like this, Grandma. I might be cumming soon," I groaned as I wanted to cum so hard, my hips moving faster, grinding my throbbing cock against her ass while holding her hips firmly.

As Sandra’s hands moved across the bedsheet, a dildo vibrator slipped out from beneath the sheets while she was straightening them.

"Wait, it’s yours?" I asked as I saw the pink vibrator, my cock twitching against her ass at the discovery.

"No, Alex... it’s not mine. Please don’t look," Sandra said, feeling embarrassed as her face turned deep red.

It was all clear now. The wet stains that I was seeing on the bedsheets were from her cumming by this vibrator. The lonely GILF had been pleasuring herself in secret, and now here I was, rubbing my massive cock against her ass while she was bent over the same bed.

Sandra’s body trembled more noticeably as she realized I had seen her secret toy. Her thick ass pushed back slightly against my cock despite her words, her breathing heavy as the embarrassment mixed with undeniable arousal.

"So you have been cumming yourself to sleep with this every night, Grandma?" I asked, my voice low and teasing as I looked at the pink vibrator on the bed.

"No, Alex... it’s not like that," Sandra said, trying to explain herself but it was obvious. The lonely GILF had been denied sexual pleasure for years. Her body had needs, and she knew it, but she had to be the grandmother who had responsibilities and cared for her children and grandchildren.

I put my hand on her trousers waistband and pulled it slowly down, bunching it under her thighs. She wasn’t wearing any panties, her mature, thick ass and pussy now completely exposed to me.

"See, you are so wet, Grandma. Your body needs this," I said as I looked at the view between her ass cheeks, her pussy glistening with arousal, her tight asshole twitching slightly as she remained bent over on all fours.

"No, Alex... please don’t look," Sandra said, her voice trembling with embarrassment as she felt completely exposed, her face burning red while her body betrayed her with how wet she was.

"Let your grandson take care of you, Grandma," I said as I put my cock on her pussy lips and coated it with her juices, rubbing the thick head up and down her wet, swollen folds.

"Ahh, fuck..." I moaned as my cock felt a rush of pleasure, the warm, slick heat of her mature pussy making my shaft throb with need.
