Mike came home from school, dropped his schoolbooks and grabbed a beer out of the fridge. He walked slowly back to his moms room dropping his clothes along the way until pushing open the bedroom door he was completely naked his thick rod jutting out in front of him.
He had been thinking about his mom all evening listening to the lecturer drone on and on about some geopolitical bullshit all the while sneaking strokes on his cock thinking about his mom tied up and gagged in the bedroom at home.
He tied her up with her hands between her legs and tied her hands to her ankles before leaving earlier that evening. With her head pulled down and her ass pointing up he gave her a few quick spanks on her upturned ass, slid the vibrator into her wet pussy, clicked it on to medium and then gagged her and left for school.
Now two hours later, cock in hand, he stepped into the room to see how she was. Wet, was how she was. He couldn't guess how many orgasms she had had but she was soaked with sweat. Her thighs were coated with pussy juice; her hair was messed from twisting and turning and the room smelled like sex.
Mike stopped in the doorway to enjoy the scene in front of him. His moms' nice round ass was pointing at him and he casually stroked his cock as he watched it writhe and twist as the vibrator hummed away. Small mewling sounds and moaning escaped around the ball gag fitted into her throat. He walked over to her side. Her eyes came up to his and he could see them begging for release. Taking off the ball gag he gave her a few sips of the beer to sooth her parched throat. Then leaning forward he slid the head of his dick between her lips. She started sucking on his cock lifting her head up and down as much as she could bound the way she was and with every stroke of her full lips up and down his cock she seemed to cum again and again.
"Ah" Mike groaned as his cock slid in and out of his moms' hot wet mouth. He reached back and flicked the vibrator to high and watched in pleasure as his moms' ass began to hump up and down while she hungrily sucked at his cock. Slowly sipping his beer mike just relaxed and enjoyed the blowjob he was getting as he watched his moms round white cheeks move around the vibrating dildo buried deep in her pussy. He knew if he stayed there for much longer with his cock being treated to these ministrations he was going to blow his load down his moms' throat in no time. He couldn't decide whether to let her continue or to pull his cock out and slide it deep into her soaking wet pussy. Thinking how much he would enjoy spanking those sweet upturned cheeks he decided he would let her suck him off and drink every drop and then get nice and hard again by spanking her and then give her some deep hard fucking with his thick rod.
