It was your birthday, senior year, and your girlfriend Mandy finally agreed to have a threesome.

Her best friend Kari looks amazing, and is in full dominant mode, getting both you and Mandy hot and bothered. She starts by rubbing your cock through your pants while kissing you full on the mouth – then, when you’re rock hard, she moves over to Mandy.

You take over, rubbing absently, as you watch them nuzzle each other. Damn, son. Kari rubs your girlfriend through her skirt, and you feel sympathetic lust. Then your girlfriend’s eyes widen as she gives a small gasp. You see Kari’s finger slide even further forward. Your girlfriend’s eyes roll back, and she moans.

Crap, fuck! You yank your hand away from your crotch, but it’s too late, and your shaft pulses and squirts whether you want to yet or not. You reluctantly pant in rhythm with you girlfriend, as her lust grows and yours drains into your pants, yours slowing while hers is just getting started.

Kari looks over at you and grins, chewing on her lip, keeping Mandy on the edge of bliss. “Awww, guess you’ll have to sit this one out. Too bad, I had great plans for you too!” She winks and giggles, then shifts all her focus back to Mandy, as you rub your soft, sticky pants in vain.
