David truly hasn't got a chance in this. His massive mother's grip keeps him firmly buried in her boob and belly flab as she goes relentlessly towards her bedroom. She manages to grab the phone on the way and hurriedly dials some numbers.
"I'm sorry, sweetie," she says, still in tears and with a slight slur to her words (has she been drinking as well?), "I need you today. I'm callin' the school and saying you're sick today. School may be important but this is more important."
David is a little shocked at that. His mother would normally never let him miss school. Maybe she has been drinking. She quickly tells the voice on the other end that David woke up with a fever and will be out of school for a few days. He has an otherwise perfect attendance record, so it's doubtful that there will be any problem as far as the school is concerned, but for mom to do that...things must really be bad. He doesn't get much time to reflect on that because she's soon in the bedroom and has tossed him unceremoniously onto the gigantic reenforced bed. Then she shocked David again by stripping the clothing from her body, revealing all that she has, her gigantic floppy tits topped with large gumdrop-shaped nipples, her gargantuan belly, her wobbling thighs and her colossal jiggling ass. It's only once she's naked and sees his shocked expression that she seems to realize what she's done. Her glassy-eyed expression tells David that she has definitely had a few drinks and her smile tells him that she has completely misread his reaction.
"Aww...look at you," she says, now running her pudgy hands over herself, "Here I am chasing all over creation to find a man who can stand to look at me naked and here's my own son unable to take his eyes off me. I should be spanking you for being so naughty to find your own mommy sexy...but...oh god it's been so long since I man looked at me like that. I can't help myself."
David should take the opportunity to escape. He should at least make an effort to stop her. His mother's not in her right mind, he tells himself. She doesn't know what she's doing. Still, he stared in frozen fascination as his own mother, now wide eyed and running a big cow-like tongue over her thick lips, scrambles onto the bed to pin him down and traps his cheeks between fat and greedy hands.
"I know this is wrong," she says in a kind of attenuated moan, "but I don't care anymore. I don't want to think. I have a man right here and I want to feel like a woman again."
David opened his mouth to finally say something and it's suddenly full of her tongue. She kisses him like crazy, slurping on his lips and a good portion of the rest of his face, her tongue thrashing about like an eel between his cheeks. He finally tried to move, but she seems to take it as writhing in pleasure or something, because she doesn't let up. With his face occupied, her hands are feeling him all over, running up and down, in and under his shirt and already pulling at his pants to free his (admittedly quite large but involuntary) erection. When her hand finds that, she releases his mouth and smiles triumphantly.
"I knew it," she says, "I knew you wanted me, and right now I need you. I need you to fuck me right now and make me feel desirable again."
