Just when I thought it couldn't get any better, I sunk deeper and she began to deep throat me with short, rapid strokes. I could feel the slimy flesh ...f her gullet milking me hard. I began to buck my hips, literally fucking mom's throat. My balls tightened. This was it!"Oh, mom, I'm gonna cum!" I groaned.She worked harder and faster, slurping up and down the length of me, her tongue going into overdrive. Mom tightened her lips, loudened her humming. She was like a cocksucking machine on. . I don't think I could take it.Finally she stop with a little sigh, "Ah well, enough fun sweetling, nowplug yourself in and lock up like a good girl."I nod and fit the cable in, starting the vibe back up, and pull my skirtdown, before sitting down, cautiously and locking up my ankle chain. Shebends down to check it, more an excuse to feel up my leg again, thananything else."I'll see you again sweetie," she says tenderly moving her hand betweenmy thighs and stroking my leg under the skirt,. The light from the tube light showed across her legs and stomach. Her legs were spread open and I peered down at her pussy. Her cunt was gaping wide open and cum was all over her face, breasts, stomach, pussy and legs. Her hairless cunt lips were engorged and glowing red. Her inner walls of pussy was pink and swollen. Her nipples thrust out like pencil top erasers. She looked like a slut with satisfied look on face.Even her clit was standing at attention. I was completely shocked. Some one had. At weekends she would sneak over to my house under the guise of going to see friends, and we would spend the day either making slow, passionate love in bed, or fucking like rabbits in every other room of my little two-bedroom suburban. Not once did either of us even mention birth control, and I naturally assumed that she had it all under control.So imagine my surprise when, just after spring break, she turned up on my doorstep in a flood of tears, a suitcase in one hand and a positive pregnancy.
