Rachel awoke the next morning with her son's dick already burning a hole in her mind. She couldn't seem to think about anything else, like she was a woman possessed. Her hand was already in her pussy, madly frigging herself. She thought that her hand was probably there all night while she slept. Rachel could still taste her son's cum in her mouth and she new that it was wrong but she just had to get more cum in her mouth as soon as she could.
She got up and made her way to her son's room, wondering if he was awake yet. She didn't even notice that she was still naked, her tits hanging out freely and her pussy leaking her cum all down her leg as she walked, all she knew was that she had to play with Bobby's huge cock some more. She made her way into the room without even knocking first and was a little disappointed to find that her son was still asleep in his bed. Oh well, she though, I'll just give him a kiss and madly finger myself while I wait for him to wake up. She made her way over to his bed and leaned over to give him a kiss on his forehead. As she did so, however, she noticed that there was already a huge tent in his blankets made by his already erect cock.
She stood back up and her hand had already resumed playing with her pussy. She used her other hand to remove the blanket that was blocking her view of his penis, and his cock came into sight. She looked up at his face but he was still asleep. Oh God, she thought, so fucking big, I just want to straddle him right now and fuck his brains out. Oh, if only I could do that without waking him, then he wouldn't know that his own mother had come in here and fucked him silly.
As she came out of her thoughts she noticed that her other hand was already stroking her son's cock. Pre-cum was leaking out of his cockhead and all over her hand. She stopped frigging herself with her other hand and used it to poke her son in his head. He didn't stir and she smiled. Throwing all caution to the wind she leaned into his cock and enveloped it with her mouth. She couldn't take all of it in due to it's shear size, but she took in as much as she could and jerked the bottom half of his cock with both her hands.
Bobby started to stir and she pulled back, taking both her mouth and her hands off of his beautiful cock. He hadn't yet opened his eyes. He was thinking, Wow what a wonderful dream, my incredibly hot mom jerked me off in the bathroom and let me cum all over her face chest and pussy. Too bad it was just a dream though. He opened his eyes then and looked up. His mom was still sitting there, and she was naked as the day she was born, he looked from her magnificent boobs to her sopping wet pussy. Damn, he thought, my mom must be one horny woman to be in here already.
"Hi sweetie," Rachel said to Bobby. "Have a good sleep?" She really wanted to start sucking his dick again, but she felt too weird about it because this was her son and all. Sure she had just been sucking him off, but with him being awake it seemed different somehow.
"It was alright mom," Bobby replied, "but what are you doing in here so early? And why are you naked, you know it's not right to show your, um, stuff to me like this."
"Oh," she looked down at herself as if noticing for the first time her nudity, "Well, the doctor had said that I should take care of your pressure in the morning, and I didn't want to get any of your delicious semen on any of my clothes."
Bobby nearly passed out when she called his cum "delicious." Oh my God, he thought, she must really like the taste of cum! I never knew that my mom could be such a slut.
"So honey," Rachel said, "I see that you could use my help. Ready for your mommy's hand?"
Bobby, a little too dumbfounded to speak, could just nod. His mom then put her hands back on his cock and started feeling it up and down. She could feel her warm saliva on him and pre-cum started to mingle with it, which made her even hornier. Her pussy was now so hot and bothered that she was leaving a stain on her sons bed. In a daze she took her other hand and started fondling her right tit, paying extra attention to her nipple. She always liked it when people played with her tits, sometimes she could cum just from that.
Bobby watched as she played with her big boob. He could feel the cum rising in his balls and knew that any second he was going to cum. However right before he shot the phone rang. The noise really surprised them both and Rachel took her hands away from her tit and her son's cock, she then reached over to Bobby's bed side table and picked up his phone.
"Hello," Rachel said into the receiver. She listened intently for a minute while Bobby looked her up and down. He could see that her shaved pussy was now wet with her juices making him even harder than before if that were possible. He really just wanted to reach over and start finger fucking her, and he almost did the only thing holding him back was the thought that this was his mom, not his own personal fuck toy.
Finally Rachel hang up the phone and turned back to Bobby. "That was Dr. White, she said that something odd came up in the test of your semen and that she would stop by around noon in order to further examine your cock, um, I mean, your penis." She smiled, "So then, about time for us to get back to work." With that she reached over and started stroking him again. Not waiting long before she put her hand back on her tit.
Although Bobby was interrupted and not able to cum before, it didn't take him long until he felt his balls start to boil with his hot semen and he knew he was about to cum. He breathed heavily in through his nose and noticed for the first time just how heavily the smell of his mother's cunt hung in the room. That made him lose control, he yelled to his mom that he was cumming and his cock began to unleash his monster load of cum. The first rope rocketed straight into the air and came down all over his chest, Rachel's hand and arm and the bed. His mom watching this started to twist her nipple so hard she was surprised she didn't start bleeding. Another torrent of her son's semen came gushing out of his cock and all over them and the bed. She noticed just how much come was getting on the bed and said, "Now Bobby you don't want to stain your sheets" and with that justified in her own mind dropping her head back to his cock and shoving her mouth over his cock and swallowing the next blast of her son's hot cum.
Bobby was in shock, if he wasn't already cumming so fucking hard he probably would have passed out from the sight before him. His mom had just stuck her mouth on his cock and was swallowing a huge load of his cum. He had never received a blow job before (to his knowledge) and having a big breasted hotty like his mom suddenly sucking all his cum from his dick was nearly too much for him. If he hadn't already been coming he would surely have blown his load. He watched as his hot mom tried to swallow all the cum bursting from his pecker, however it seemed to be too much for her and her she had to take her mouth off of his cock in order to swallow her mouthful of his semen. When she did that another blast of cum came bursting from his cockhead and hit her dead center on her face. She shut her eyes just in time before it ran all over her eyelids and brows and down her cheeks and mouth. His next few shots hit her in the face and Bobby, regaining some mental control of what was happening, grabbed his cock and shot the rest of his load all over her tits.
By the end of it Rachel was a complete mess. She took her hands and started to wipe the cum from her face and shove it into her mouth in complete view of Bobby. She no longer cared if he watched or not, in fact she was starting to get even wetter at the thought of her son watching her eating his cum right in front of him. She hadn't cum yet and had half a mind to start fucking herself with reckless abandon but a little voice in the back of the head was saying that things had already gone a bit too far and that she should try to restrain herself at least a little bit.
Bobby, however, really just wanted to get out of that room. He thought that his mom eating his cum was one of the hottest things he'd ever seen, but it just seemed so wrong that he had to leave. He got up and ran to the bathroom, not even saying something to his mom. He started the shower and got in.
