Jake smiled as he rang the bell on Jennifer's house, he'd been hoping that she'd call, with her parents being out of town this would be the only chance they'd have for the next three months. When the door swung open he was openly surprised, "Woah, babe, when did this happen?" Gesturing inelegantly at her larger breasts.
Jennifer just giggled, "Just get in here, you can talk about my breasts without compliments once you get a pair of your own." With the door closing they kissed, Jennifer surprising Jake with an uncharacteristic aggressiveness, even as her tongue forcefully parted his opening lips he could feel her nipples through her shirt. Surprise became a smile even as their tongues danced, he knew he was going to get laid tonight if things were starting off like this.
They barely made it to Jennifer's room before she almost literally torn her top off, the fabric audibly stretching as she fumbled at the buttons, her bare breasts heaving, defying gravity before Jake as he fumbled at the belt Jennifer wore, holding her tight jeans up, Jennifer doing the same to his own with one hand, the other behind his head, the two standing together the same height.
The rest of their clothes were removed in a rush, his pants thrown to the end of the bed as Jake held her close as he jumped onto it, Jennifer gasping at surprise before gently slapping him, "Hey, warn me next time okay?" He smiled, "I thought you liked surprises?"
He carefully pulled out a condom from his pants pocket as the lay on their sides, facing one another, tearing the packaging open with his teeth with a grin. Biting her lip, Jennifer took one side of the Condom as the two together put it on his stiffened rod, his other, after throwing the wrapping away, gently rubbing her hood as she pulled the two of them closer together, her breasts rubbing nicely upon him.
Jennifer wrapped her legs around Jake as he used one hand to guide himself in, and carefully, sneakily, brought the other round to cup her ass, before sticking a finger into her hole as his penis entered her pussy, smiling at the gasp and shocked look she gave him before he started to move, forward with both dick and finger and the shock turned to moan. "Oh, Oh, damn Jake that's, oh...hmmm."
Three condoms and an hour later Jake left, looking up into his girlfriends eyes after their kiss, not noticing or caring that she had grown, as Jennifer herself would discover when she got dressed the next day, the day of the bake sale.
