a hard throbbing penis in his speedo!

this is a fictional story of 19 yo guy, and his almost 38 yo pregnant mom, and no real name were ever used at all.

he was just 19, and it was in the early 1990's and his sexy slim mom was 37, almost 38, and she had always been single from what her son could remember.

it was on such a hot summer day and that his mom was dressed in only big panties that swept way high up over her belly button (for the 1st time since her pregnancy with her son), and her bra, all revealing so very little of her almost still flat tummy!

her son was only wearing his tight fitting striped speedo that kept his penis hard throbbing off and on all that day, especially cuz of the air conditioner being off due to brown outs that were quite common back then, and that his penis would also be so hard throbbing that much more in that speedo of his, cuz especially of the way his mom's tummy had looked in those big panties of hers!

it was at the very moment his mom was leaning against the wall fanning herself when she said she needed to talk with her son, and she'd said, "sweety, you probably haven't noticed that mommy's tummy's starting to swell a little."

her son did notice, and he was really stunned in silence, especially cuz of what his mom had said about her slighly swelling tummy, especially cuz of those big panties of hers!

what had really made her son's penis throb even that much harder in his striped speedo, was when his mom had said, "the reason is, mommy's just a little more than 3 mos pregnant, and just starting to show."

for a moment, her awkward feeling son had forgot exactly what his mom had just said, though he'd said something like, "what...how...
i mean, who is the..." his mom had cut him off by saying, "never mind how, and never mind who, none of that matters, the point is before long you're going to have a baby sister (or brother), isn't it exciting?" with such awkwardness her son had said, "i guess..."

as he'd just awkwardly stared at his mom's tummy just between the top of those big panties, and her bra, also after just a few seconds she'd took one of his hands and had put it across the front of her big panties, and that he just could not resist caressing his mom's panties anyway, his mom had said, "there's something of a swell there, can you feel it?" her son had said with so very much sexual arousal, "ouh, wow! yes! i can-i can feel it!"

though he doesn't know why, he just kept rubbing at the front of his mom's big panties and as he's done so, she said, "mommy's really going to need your help in the next few months and especially after the baby is born, you're the man of the house, i'm counting on you sweety, are you up for it?" he'd said with awkwardness, "i guess so."

for whatever reason, he knelt lower and kissed his mom's somewhat visible baby bump. she'd said "ouh! ouh! that's so-so sexy, sweety!"

just then, her son had just barely realized that his hard throbbing penis was on the dire brink of blowing huge amounts of cum all through his speedo crotch, he'd got up very quickly, and was when his mom had said, "well, that's all i wanted to say, sweety. we'll talk more later."

right then, her son had run straight to the bathroom, especially since he just could not resist masturbating in his speedo, especially from checking out his pregnant mom's tummy in those big panties of hers, and her bra, and so then, that was when her son had gushed out a huge cum load all up in his speedo crotch in no time flat!
