Where does John want to cum?
On her tits
John's gaze immediately flicked downwards, towards the cleavage that threatened to burst from Rachel's half-zipped sweatshirt.
Rachel smirked and slowly unzipped her jacket, revealing her nude breasts underneath. Her nipples hardened against the crisp October air, and John's eyes went wide. They were perfect C-cups, pert and pale and — Rachel liked to brag about this — all natural. A little more pre-cum trickled from the head of John's penis.
"Alright, John," Rachel giggled. "Hold your horses."
She wrapped first one hand, then the other around his erect cock. John was a little on the small side, only five inches, so her hands enveloped his cock almost completely. She used this to her advantage, squeezing and stroking his entire shaft with such intensity that John looked like he might black out.
"Look at my young home wrecker tits, John, baby," Rachel purred. "Aren't they so much better than your wife's?"
That did it, driving him over the edge. John's hips bucked once, twice, and then finally he unleashed himself, cum spraying like a fountain over Rachel's once pristine breasts.
When his shuddering groans had finally subsided, John looked horrified, staring down at Rachel's cum-covered chest with a mixture of sick desire and shame. "I-I can't believe..."
The beep of a car sounded from somewhere in the distance. A car had just pulled up to John's driveway. "Oh god, she's home!"
