Chapter 1
It was late in our first pregnancy that my 19 year old bride, Sophia, proposed that I should start using her 18 year old sister as my "side pussy." In fact it was during a lull in a protracted evening of fucking that she first described the idea to me. Her already fat tits had grown a cup size and her rounded belly looked almost like a joke on her slim frame. Like a girl pretending to be pregnant by jamming a basketball under her shirt.
This meant that we had to choose our positions carefully.
The hard gymnastic hammering I'd accustomed her to when I'd taken her to my bed during her freshman year in college had to be replaced by slower more sensual encounters as her low back could no longer stand up to the weight of her swollen udders whipping back and forth when I took it in to my head to pound her cross eyed. And with her womb full to bursting with our daughter she couldn't use her pussy to fully accommodate me.
Luckily from the start of our relationship I'd made clear that I would brook no squeamishness from her with respect to taking a good buttfucking when and however I required it. After her initial trepidation, and my having to force my prick up her shit-chute while pinning her in a half nelson and muffling her pleas that I was "too big, uhhhhhnnnn, too big," she'd learned that nothing made her cum quite as hard as having her guts full of my big unrelenting cock.
It was within only a few weeks of my having staked my claim to her anus and taken her from nervous anal-virgin to eager butt-bitch, that she'd tearfully confessed to me--between slurps on the flaccid cock I'd just unsheathed from her still gaping behind, that it was my plundering of her final virginity & refusal to "take no for an answer" that had completely convinced her that she was in love with me.
"You made me feel owned. Made me feel like I belonged to you, only to you, that I was your property. It made me feel so safe and so desired. When you've got this fat-cock in my bootyhole..." Here she trailed off sniffling, an 18 year old wracked with emotion but inarticulate in the face of her deepest feelings, and preferring to suck more vigorously on the head of my dick than to try and express the inexpressible. Meanwhile I was moved as well--head over heels for the busty young thing I'd been making into my cock-crazed little slut.
Being barely 20 myself at the time her naked confession punctuated by her suckling at the cock still pungent with the tang of her colon and the heavy load of nut butter I'd deposited there, was more than enough to get my fuck-sword back to full attention. She gazed up at my rampant 10 inches in the reverent mix of awe and intimidation that a big dick inspires, her mouth slack and her eyes wide. Her gaze flicked to my face and without a word she turned and splayed herself face down on the bed again, reaching back with both hands to flatten her buttocks out of the way. Her pussy was swollen and slick with her juices, while her anus was still trying to resume its normal dimensions even as bubbles of my baby batter percolated out of her in steady pulses.
I mounted her without preamble. Drilling down into her harder than she could have handled weeks before. Her depths clenched at my woman-tamer, and she emitted a steady ecstatic moan through the teeth she'd clenched around her sheets. Soon her roommate doubtlessly heard her barks and whimpers and then her incockxitated voice crying "Hurt me papi! Oh godddd! Hurt your little bitch" coming through the wall of her dorm room.
Is it any wonder I'd made her my wife?
So many months later, I was spooning my woman, her womb swollen with my seed, and her asshole stretched tight as a glove around the base of my cock. She was catching her breath after her fifth or sixth orgasm while I cupped & kneaded her mammaries while gently stirring my lance in her guts.
"Daddy," (ever since I'd knocked her up I was "daddy" in and out of the bedroom), "I've been thinking."
"I thought Daddy did the thinking in this relationship?" I joked, punctuating my words with a little thrust of my hips that made her gasp.
"It's true daddy," she looked back over her shoulder at me, letting the pools of her eyes open to the penetration of my gaze, a young girl that I'd made into a woman. She squeezed the muscles in her depths around the shaft that was rearranging her insides, and bit her lip hard without breaking our gaze.
"But a good boss still needs to listen to his underlings, right?"she said, & I nodded and she smiled before another little thrust into her colon forced another gasping breath and made her heavy jugs jump in my grasping fists.
"And you're the best boss ever so..."
I gave her a series of staccato thrusts, not even pulling my cock in and out, just shifting my hips rhythmically and causing her to hunch and jerk forward and back like a puppet or ventriloquist dummy where the arm up the things backside had been replaced by a big ass-invading prick in our scenario.
I pulled on her udders and whispered in her ear "Ok, what's my little milk cow got to say?"
