Thinking back on what happened here, I do feel I acted quite foolishly. Honestly, I wonder how i didn't see this all coming. Let me not spoil it for you. Enjoy.
***
"Harry. Harry. Wake up" my Mum's voice echoed in my head, I opened my eyes, she was standing at the door, forearms folded and one arm resting on the door frame.
"Yeah I'm awake, I'm awake," I said groggily as I sat up looking around to see if I'd left any evidence of my masturbation lying around.
"What happened?" I asked.
"I need you to go get some things from the grocery store for me, would've gone myself but I'm making dinner."
"Alright Mum. Gimme a second to get ready."
"Okay," she said still standing still there waiting for me to get up.
"Uhm, Mum I uhm, I'm ahh sorta... You know..." I rambled awkwardly gesturing to my body from the waist down, I was nude.
"Ohhhh, I'm sorry honey I didn't realise," she smiled and put one hand over her lips and turned to go. "It's not like I haven't seen it all before though," she said as she disappeared from view.
"Mum!" I said trying to act 'normal', in actuality I wanted her to walk over to my bed and shove my cock deep inside her throat, coating it with her saliva as she played with herself, i knew she wanted it too but we both were pretending at the moment, i think. "I need to do something about this," I thought referring to the situation then I looked down at my blanket, I already had a hard-on. I could hear her laughing as she walked away because of my reaction.
I stood up from the bed, took a quick shower and set off for the grocery store after collecting Mum's credit card and car key.
I got back home about forty-five minutes later, dropped Mum's key on the living room table and stepped into the kitchen to see what we were having for dinner, it was Turkey and a special sauce she liked to make every now and then, "Yum," I said trying to stop myself from grabbing a piece.
"Mum I'm home!" I announced, there was no answer so i decided to go let her know I was here so she'd come out for dinner.
When I got to her room I saw that the door was almost closed, I knocked but she didn't answer, I didn't want to peep so I knocked again and then, "Oh God yes," came her desperate moan from inside, I opened the door just a bit and saw my Mum, headphones in her ear, eyes glued to a laptop screen and a vibrator on her clit, she was watching porn, thankfully she wasn't facing the door.
"Holy shit," i exclaimed under my breath with eyes widened.
I wanted to barge in and see what would happen but decided against it, because I wasn't sure how she'd react, although the fact that she just recently started leaving her door open was proof enough that she wanted something, a part of me still had doubts, I loved watching her make love to her pussy and I didn't want it to stop.
I took out my cock which was slowly gaining length from my pants and stroked it softly as I watched my hot Mum moan in pleasure as her orgasm drew nearer. "Yes baby, fuck mummy's pussy. Fucking make her cum," she whispered, I almost didn't hear her.
My cock stood at full length now, I stroked faster, those words turned me on, I wanted to put my cock inside her so bad, "Your baby's right here Mum," I thought to myself.
I couldn't help but think she knew I was watching and it turned me on even more. Suddenly she arched her back and started to jerk her hips back and forth, "Ohhh yesssss. Fuuuuck" she whispered as she started shaking violently, her vibrator still on her clit for a few seconds until she couldn't take it anymore, she lay there shaking as she rode the waves of her orgasm.
I stroked harder trying to cum right after her but she was already done thrashing around and I was nowhere near close; masturbating with a dry cock didn't feel as good as with lube. She sat up and I knew I wouldn't be able to finish here so I left for my room, I wanted to cum so bad, I didn't even bother putting my dick back in my pants, I just walked swiftly to my door with my dick swinging left and right in the air.
As i got to my door I impatiently opened it noisily and it seems she'd turned off her porn because she called out, "Harry! Is that you honey? Come down for dinner before it gets cold, don't make me come and get you."
"Fuck," I mouthed, I knew she wasn't joking but I really wanted to cum. "Alright Mum, I'll be down in a second," I opened the door, stepped in, put my back against the door and continued to stroke my dick as fast as I could without killing the pleasure and I thought of my naked Mum as she watched porn, I imagined myself walking into the room, unnoticed until i stuck my dick into her pussy...
Then there was a knock on my door, "Harry, where are you? Turkeys not gonna eat itself." She turned the door knob, that sent a shock wave through my body, the blood flowed back into my brain and I knew I had to stop. I stuck my dick right back inside my pants with the head facing my head and my pants holding the shaft so it wouldn't be so visible.
I opened the door before she did, "Alright I'm coming, just how good is this Turkey anyway?" Then I looked at her and my dick twitched in my pants.
From the waist up Mum wore a smile and a crop top that barely covered her boobs, she wasn't even wearing a bra, I could see the lower fleshy skin of her massive jugs peering through the underside of the crop top, they were calling me to grab them whole and suck on their nipples. Thinking about it now, I probably should have said something about her 'inappropriate' dressing but I was in too deep at that point to even comprehend the moral implications of what was going on.
