In early November 94, my mom then 31, invited me then 11, to share a bed with her at a motel room one night insead of those rollup beds. She wore a sheer nighty, I saw right through her nighty to her tummy control panties, to keep just her tummy flat, and bra underneath.
My mom had one sexy body, and my cock grew all nice ,and hard in my underpants. That night I had one huge cum in my underpants, suprisingly none of that cum jizz got on the bed sheets, just in my underpants. We'd both belonged to a gym membership since I'd been 8 years old, we'd both wore spandex short shorts, my mom wore her sports bras, even at 8 years old at the time, my mom's tummy was something sexy to look at.
From November 94 to late January 95, my mom had still worn her spandex attire as always, short shorts, and bra, my cock would harden big time in my spandex short shorts just from how sexy flat her tummy had looked then.
One night, on the last Friday January 95, I was getting ready for bed, then my mom invited me to sleep with her, before we got in bed, she had something to show me. She lifted her nighty up to her bra, her tummy was still nice, and flat included underneath the front of her panties.
Then my mom took my hand on the front of her panties, my cock got so nice and hard in my underpants, she smiled "We're 2 and a half months pregnant honey, isn't that exciting?"
When I said "Who's the..." My mom cut me short, and said "Remember that weekend back in November (94) at that motel when we slept together, well guess what, I'm carrying your baby, isn't that exciting honey?" When my mom held her nighty up over her bra, I felt our baby moving around in her tummy, my cock got real big in my underpants, especially from looking at her still flat tummy back then. That night, I learned the intimate truth about hard cocks, a guy doesn't need to have sex with a woman to make her pregnant.
Then weeks later, the first Sunday in April, I turned 12, then 3 days later, my mom turned 32. Then on spring break, my mom's pregnancy started showing the Tuesday before easter Sunday. On that previus Monday night, I was at a friend's spring break sleepover, and when I got home in the middle of that Tuesday, my mom was at work. When she got home from work that day, she was in maternity clothes, a skirt, and matching top hung way over her breasts, my cock got all hard in my denim short shorts.
Then when I asked my mom how her day was at work, she'd smiled, lifted up her top to her bra, I thought oh wow! There was just a little sliver of her showing tummy bare between the stretchy panel of her skirt, and what I saw of her bra. When I felt our baby, my cock began throbbing in my shorts so hard, huge loads of cum gushed out in my shorts, her tummy was so almost round then.
