I pretended to stir from my slumber and sat up.
"Can you scratch my back?"
I folded my arms in front of me to support my head as I lay over my mother's lap. My left hand draped over the inside her right knee, my right hand, a lightly balled fist, rested along her inner thigh. I pulled myself cuddled tight to her and she began to massage my back.
As she worked her way up to my neck I wiggled my head around to get more comfortable, and re-adjusted my arms for support. My left hand lightly clutching my mum's knee, as my other hand fell upon the couch nestled between her legs brushing the inside of either thigh.
She continued to massage my neck. I moved my head to get comfy again. This cause my hand to brush back and forth against her thighs. She went to rubbing my back again, and then my shoulders. My mum began to massage my upper arm, gently pushing on it, trapping my hand against the warmth of her crotch. I could tell she enjoyed the solid muscle of my arms as she was feeling them up a while. As mum rubbed up and down my bicep, my fist would brush against her hot covered sex. I pretended to fidget a little, giving the slightest wiggle of my knuckles when she would push my arm toward her pelvis.
I think she was starting to get embarrassed, about trying to get off on her son's hand, or sick of her son trying to molest her, when she said "Ooff, You're getting a little heavy," got up and went to the kitchen for a drink. She did come back into the living room after a while and sat at the far end of the couch again.
"Foot rub?"I asked her.
"Sure." She said.
I put one foot up for her to rub and the other I rested on her lap.
"Oh, for you?" She said jokingly.
She settled back into the couch, picking my foot up off her lap and began to knead the bottom of it. I set my other foot down. It rested in the valley created by my mother sitting with her legs together. After a few minutes her legs relaxed and fell apart slightly, dropping my foot to the couch. I adjusted my body quite obviously, moving around a lot, finally settling in with my foot pushed against her crotch.
She then let go of my one foot picked up the other and began to rub again. The free foot fell between her legs halfway up her thigh. I ever so slowly, ever so lightly, rubbed my foot back and forth along the inside of my mum's thigh. I moved my foot up her leg slightly and kept rubbing back and forth. She didn't seem bothered.
She was done with the one foot, set it right next to the other, up higher between her legs and then picked up the other foot and got back to massaging. I decided to continue the slow, light rub with my foot, ever nearing her pelvis. I yawned and stretched out pushing my foot up against her crotch again. I continued the, now even more slight, rubbing back and forth with my foot. I became bolder with the occasional twitch of the toe.
She was now finished with that foot. She set it back down next to the other and started to rub the other foot. This time she didn't pick up my foot. Mum merely held it in place whilst rubbing my heel. I didn't cease the movements of my foot. If anything I embellished the writhing in my foot as she massaged. As she kneaded my foot with her fingers I kneaded her pussy with my toes. When she rubbed up and down my foot, my foot ground up and down her sex. I could feel how hot and wet my mum was, nearly fucking herself with my foot.
The pace of her breathing increased. I could hear her heart pounding out of her chest. Finally, excitement got the better of her. My mum had tried to stifle herself and become still. But a short loud pant escaped her lips as her whole body twitched, causing her clit to brush up along my foot. That touch seemed to send a jolt through her as she convulsed, again dragging her clit up and down the side of my foot, lightly panting.
Reflexively she rolled her hips back. With her back against the couch her pelvis was pressed hard on my foot. I looked up at my mother. Her eyes were clenched tight and her lips slightly parted. A long low moan left her lips, a lot louder than I am sure she intended, as she ground her clit hard into me. She tried her best to stay still, her breathing quickly becoming rapid again, the taboo and excitement was too much.
Her body betrayed her as my mum humped me quickly a couple times. I watched her stifled shuddering as she began to quiver, riding atop my foot. The look on her face was one of pure pleasure and total guilt. She could no longer quiet her panting, shaky little breaths at first and then bigger gasps for breath as my mother came down from her semi-discrete orgasm.
My mum looked as beautiful and satisfied as I've ever seen her. I'm sure I'll make her feel that way again soon.
