"Oh, Kirk," she whimpered, covering his mouth with her warm, moist lips. "That feels so neat."

Kirk had fucked his share of the girls in town, and he expertly massaged his little sister's clit until she was squealing with joy. Deciding to give her even more pleasure, he began plunging his thick middle finger in and out of her little juice-drenched cunt, making certain to brush his finger against her clit with each inward thrust. The ecstasy was almost more than she could stand, and with every thrust of his plunging finger, he was carrying the squealing youngster to new heights of blissful joy.

"Oh, Kirk!" she cried, wildly rotating her slippery cunt around his thrusting finger. "Go faster, honey! Don't stop! I'm almost there!"

His wildly aroused little sister let out another squeal of joy when her body suddenly exploded into a bone-rattling orgasm, the first climax she'd ever had without using her own hands. She kept coming for what seemed hours to her, and when she finally stopped, she gave him a deep, tongue-sucking kiss.

Finally opening her eyes, she was once more aware of the big, hard boner that was throbbing up from between his legs.

"Kirk," she whispered as she began sliding his velvety foreskin up and down over his throbbing cock-shaft. "Would you like me to suck you off?"

"What do you know about blow-jobs?" he asked in a shocked voice.

"Joyce told me."

"Your friend with the big tits?"

"That's the one," she said, still lovingly stroking his tingling boner.

"Does she suck guys off?"

"Sure," said Marci, "and she loves to fuck, too."

"Can you fix me up with her?"

"I'm sure I can," Marci promised, lowering her face down toward her brother's hard cock.

Slowly and gently, she pulled his foreskin back until his big, purple cock-head was deliciously revealed. She heard her brother let out a soft moan when she enveloped his sensitive prick-head with her warm, moist mouth.
