Most people don't feel ready to have a child at 18. Stan Taylor and Marnie Clay weren't most people. They had met in middle school and crushed on each other from pretty much the moment they saw one another. They made friends through school clubs and, at 14, they asked each other out.
For the next 4 years, they had had an idyllic love life- hanging out at each other's houses, going for long walks hand-in-hand, going out to movies and making out in the boring parts, sleeping over at each other's houses.

Just to show they were serious, and because they didn't have any serious plans of college or career stuff, they decided they'd have a baby as soon after they both turned 18 as possible. They prepped themselves for months- Marnie would play with herself, making sure she'd be comfortable with Stan's cock inside her, and Stan jacked off countless times imagining getting to fill Marnie up.

Stan savored his lover's beautiful soft body, her big soft breasts and curvy hips, and Marnie loved how her lover's handsome body moved above her and his cock pounded in and out of her while his balls slapped at her.
Before either of them knew it, they hit their peaks, and clung to each other as they overflowed with pleasure. Stan felt like he pumped a lifetime's worth of his seed inside Marnie, whose pussy clung to him and milked his cock passionately. They had gasped for breath and kissed passionately before practically collapsing into each other's arms to sleep.
Soon, they would be having...
