"I've felt a hard one before, but never one this thick!" she observed as her hand reached his pubic hair.
"Why don't you ever use the right word?" he murmured weakly.
"Huh? What do you mean?" she asked, holding her fingers motionless around the base of his cock. Debbie pointed her forefinger down beneath his penis and touched his balls.
"You never say 'penis' or 'cock'...." his breath gasping involuntarily as she squeezed him. "You've said 'thing'....a few times..."
"I don't know why I said it like that. Say, are you OK?" Debbie asked, looking truly concerned about his suddenly labored breathing.
"Yes!" he groaned. He felt her briefly tighten her grip on his rod.
"You really do have a thick, um, penis," Debbie said, staring intently down at his prick in her hand. "It's hard as a rock!" she murmured, squeezing him again.
He gazed through half-closed eyes at her bare breasts with their stiff little nipples, only inches away from him. He tried to decide whether he should cover them with his hands or his mouth.
"Debbie....be careful...." he groaned.
"What's wrong? Are you OK?" she asked, glancing worried at his face. "Did I hurt something?"
"No, no...I'm fine!" he grunted. "You just can't do this without....I don't know how long...." His response was disjointed and rambling, and she didn't understand any of it.
"What's wrong?" she asked, squeezing his cock repeatedly.
"You're gonna bring me off....I can't take much more...." he gasped.
"Bring you off? What....? Oh! Are you gonna cum? Are you gonna cum?" With a wide smile on her face, Debbie finally caught his meaning.
"Y...yes!"
"In my hand? Are you gonna cum in my hand?" she asked eagerly. She vigorously squeezed and pulled on his penis again. "Are you gonna cum in my hand? Now?"
With a loud groan, his cock exploded and the first spurts of cum flew from its swollen tip. She squealed in surprise as his cream jetted over her wrist and landed in the middle of her bare stomach. His bursting penis sprayed more juice onto her, and the hot semen began to drip down her hard, flat stomach.
"Oh, man! Are you ever cumming!" Debbie exclaimed, excitedly. "Oh, man, is this something! I've never watched it before! You're getting it all over me! This is just great!"
