Before Catherine leaves the room, Zack makes up his mind. "Then, c-can I have a sample now?"
Catherine grins knowingly and leans down to whisper into Zack's ear. "Good boy, telling me what you want so honestly. Meet me in my room in ten minutes."
She blows lightly in Zack's ear, making him shiver. "The sample will be free, but you'll have to work hard if you want a [i]real[/i] taste."
Kissing Zack on the cheek, Catherine strolls out of the room, leaving Zack with a flushed face and a tent in his pants.
Zack takes a look at the clock and tries to avoid running into anyone while waiting for the time to elapse.
The first six minutes of the wait feel like an eternity, and he ends up ducking into Catherine's room a full four minutes early, unable to wait the full time.
Still sporting a not-so-impressive four-inch tent in his pants, Zack closes the door to Catherine's room behind him, his heart beating quickly as he looks about the dimly lit room.
Zack's eyes are quickly attracted to the sight of Catherine reclining on her bed in a set of revealing black lingerie.
Her gorgeous D-cup breasts are barely concealed, but Zack's attention is fixed on the massive erection jutting up from between Catherine's legs. Her erect cock is more than a foot long, so there's no way it could have fit into her lingerie bottoms in its current state.
Instead, its full length is completely on display, the sight making Zack's mind fill with desire.
"You're early...are eager to have a taste?" Catherine's voice is soft and seductive, filled with what sounds like arousal.
Zack walks forwards, unable to stay patient, but as he moves to climb onto Catherine's bed, she moves a foot into his path, pushing him back.
"Clothes off first..." She lightly rubs her huge meat with one hand, sighing with pleasure. "Strip for me, Zack..."
Unable to look away from Catherine's beautiful, throbbing cock, Zack peels off his own clothing, then, as Catherine shifts her foot out of the way, climbs up between Catherine's legs to approach her monster cock.
Kneeling between Catherine's legs, and more aroused than he's ever been in his life, Zack stops for a moment to stare at the masterpiece of phallic evolution before him.
Catherine's giant cock is well over a foot and with a girth to match. Her cock-head is mostly covered by her foreskin, but Zack can clearly see the slit inside glistening with pre-cum.
The close-up view makes his head spin with and uncontrollable desire to taste Catherine's cum, and as he leans closer, Catherine's voice urges him on. "Here's your sample...lick it up, Zack."
He extends his tongue and runs it along the slit of Catherine's penis, scooping up her salty pre-cum and swallowing it eagerly. Then, unable to stop himself, Zack licks underneath Catherine's foreskin, gathering up more of her delicious pre-cum and swallowing.
Having devoured all the cum in front of him, Zack looks up hopefully at Catherine, who in turn gazes down at him with a satisfied expression.
"Did you enjoy your sample? It really is better right from the source, isn't it?"
Mouth sticky and still filled with the irresistible taste of Catherine's cum, Zack nods and stares up at her, waiting to hear what he needs to do for more.
