The panties were now on the floor as Roy carefully pushed mom's legs apart exposing her sex. I was shouting at myself to do something, but my limbs refused to move. Even from my distance I could see mom's clitoris poking out between her labia lips. It was my first view of a woman's private parts that were not on a computer screen or in a magazine. My breathing was becoming harder as I saw Roy lean forward and gently lick mom's clitoris and then I distinctly heard mom moan. So did Roy. He pulled a little back away from her grinning and as he did so I could see that mom's clitoris was slightly puffed up.

Roy leaned forward again, pushing his face into her sex and this time began an unhurried continuous licking and sucking. I felt jealous that he seemed to know exactly what to do. Although mom was not fully conscious she was now moaning loudly and I could see unbelievably that she seemed to be slightly pushing her pelvis up at his face. Roy reached his hands above him and squeezed a breast in each hand as he continued to lather her sex organs with his tongue. Mom's moans were getting louder and louder.
It was at this point that Roy lifted himself up and, gripping mom's thighs, pulled her lower down to the edge of the bed and spread her legs. Mom's eyes were beginning to flicker and, although Roy could tell she was gaining consciousness, he was determined to carry on. I ashamedly was aware that I was silently urging him to continue.
Roy placed the meaty head of his boner at mom's entrance and it was at that point that mom's eyes opened wide to see Roy. Her mouth opened to give an astonished scream but the sound quickly changed to a loud sexual moan as Roy stabbed his cock deep inside her. Mom was wide awake now and although she pawed at his chest with her hands as if attempting to push him off, she couldn't help her pelvis thrusting back at him.

Roy had done his oral work so well that mom was close to a climax even before he started fucking her. Mom now knew exactly where she was. She understood that the schoolboy next door whom she detested intensely was now fucking her but instead of trying to throw him off, her body was now reacting to having a cock inside her for the first time in months.
She lowered her hands, which had been pawing ineffectively at Roy's chest, to her sides and gripped the sheet fiercely with both sets of fingers. Roy laughed gleefully as he noted her giving up her struggle to stop him. He was fucking her forcefully, pulling back then thrusting forward. He had got into the strong rhythm that I had always imagined would be the way I would fuck my first woman.
I wondered how the sensation would feel to him, but was soon enlightened by Roy's running commentary.

"Oh you slutty mommy! You're so wet but also so tight!"
Mom groaned in agonised shame. I knew that the reason for her tightness was that dad's cock had not been penetrating and stretching her for the last six months and for the same reason her body was desperate for sex.
At least she was not staring at Roy now. Her eyes had become half closed and unfocussed as her sexual fervour dominated her mind and body. Roy did not want to rush things. He steadied his rhythm and began running his hands up and down her nylon clad legs, lingering and exploring above her stocking tops, pinching her pink thighs. Mom continued thrusting back with her pelvis, trying to suck into her vagina as much of Roy's hot hard boner as possible.
She continued to moan in ecstasy and shame with each of Roy's stabs until Roy silenced her by thrusting his tongue into her open mouth. I knew she would find it impossible to stop her mouth enjoying wrestling with his teenage tongue and it was Roy who broke away in the end, to get his breath.
Roy seemed to be working out how he could make fucking her last for as long as possible, when mom took control. She instinctively stretched her arms back and grabbed the bedrail. Then, with her hands gripping the rail to give her leverage, she wrapped her legs around Roy's ass and started ferociously pulling Roy inside her. As she did so Roy automatically pulled back allowing her to drag him into her again and again, pulling his boner firmly up her vaginal sheath.

Roy was also groaning now in time to their fuck rhythm and grabbed and squeezed mom's tits. That seemed to do it for the two of them as mom dragged Roy into her for one last time and they both shuddered as their orgasms struck. Roy moaned with each firing of his pulsing shots of cum. Mom, I sensed, was moaning in time to her vaginal contractions sucking Roy's cum deep inside her. I was firing shot after shot into a wad of tissues in my hand.
I don't know precisely what happened after that as I walked speedily to my room and hid behind the door. Shortly afterwards I heard Roy head quickly down the stairs, letting himself out of the backdoor. Then I heard mom going into her bathroom and turning on the shower.
I didn't have long to think about things as I suddenly heard dad ringing the front doorbell to be let in. I walked down the stairs and opened the door. Dad's expression was of concern. He was obviously feeling guilty about not coming back earlier to see mom and he walked fairly quickly up the stairs. Mom was just coming out of the shower as he got to their room. I heard him ask her if she was feeling better and her responding quietly that she was feeling fine.

I then realized that she intended to say nothing. After all, what could she say? She could hardly say that Roy took advantage of her but then she could not help fucking him back.
I went to bed that night still in shock from what I'd seen. Mom had clearly hated giving in to Roy's ravishment but was unable to prevent her body responding. The thought of what had happened horrified me, but at the same time sexually excited me. I lay in bed jacking off feverishly as I relived Roy's violation of mom in my mind.
