Christy sucks him off

Your girlfriend began to pull down his suspenders and undo his fly, but was stopped by Rob.

"A-are you sure we should be doing this?" He asked, flustered. "Wouldn't John be angry?"

Christy giggled. "Not if he doesn't know."

She succeeded in stripping him down and she was met by his cock springing in her face, almost hitting her.

You couldn't help but admit he had a few inches on you. For being a nerd, you didn't think he'd be packing.

"Oooh..." Christy moaned. "I didn't know you had such a big cock, Rob."

"O-oh, umm, thanks Christy."

She stroked his cock slowly, needing two hands to fully pleasure his length. There was something hot about watching Christy turn on someone, especially stooping down to Rob's level.

His cock was so hard from your girlfriend and a tiny but of precum leaked out from him.

"Someone's excited," Christy jested.

She gently licked around the head of Rob's cock. You were surprised he didn't cum then and there. His knees looked unable to hold him up as Christy slowly took his length in his mouth, jerking him as she pleased him.

"You're bigger than John, you know that?" She inquired.

Rob shook his head. "N-no. Do y-you like it?"

"Like it? I LOVE it." She placed both her hands on his waist and slowly took his whole cock into her mouth until she reached the base. Rob threw his head back as your girlfriend's head became a blur as she deepthroated him with more fervor than she had ever shown you.

One Christy's hands found its way down to her glistening pussy, which she began to finger with anticipation.

You couldn't believe she was actually turned on by him.

Her head bobbed up and down off of his cock like nothing you've seen before. Moans and gurgles filled your ears as this nerd was having the ride of his life. Her tongue swirles around his length as she went all in, dedicated to pleasuring your friend.

Her mouth let go of his cock with a loud pop and a string of saliva connected the two.

"O-ooh, man," Rob moaned. "This is better than I thought!"

Christy wiped her mouth clean. "I've noticed you staring at me before, Rob. Where else do you want to explore?"
