Taking Dicktation

'Time to give this a real test,' thought John. "Alicia, turn around," he said to her, then turned to Eli. "Hey, what do you think?"

Alicia turned her head to look at John, eyes wide. "He's going to frea-- OK." She smiled and pirouetted, posing to show off her assets.

As the girl spun, her brother looked her over and nodded. "Nice rack, sis." He looked back down at his book. "Now, you two get going."

John stopped Alicia's rotation and ran his hands over her jutting chest.

"Uh? Huh! Ssstop thaaaa! Oh! Oohhhhh. Oooooohhh! John. Yes. Please. More."

"Hey, come on guys. I need to be able to focus here," Eli complained as John lifted his sister's tee shirt up over her head and dropped it on the ground.

Alica looked dazed. She was completely out of her mind with pleasure as John put a hand on her shoulder and lowered her to her knees, the other continuing to play with her chest on the way down. She giggled and instantly took the suggestion, playing with the zipper on his pants.

"I wanna suck you so bad!" she enthused, no longer caring that Eli was in the room.

"You're my little slut, aren't you," John stated, smiling.

"Yeah, I'm a bad girl." Her hand disappeared into his pants and grabbed his hard dick through his underwear.

"Guys! Come on! Get a room!" Eli stared, totally turned on, but not the least bit worried that his sister was about to felate his roomie. Doing more than asking them to stop never even crossed his mind, and even then, the only reason was that he really needed to study.

Alicia lost patience and tugged John's clothing down to his knees, kissing the tip of his penis. "Use your tits," he told her.

"Oh yes. I'm going to tit-fuck you like you've never had it before," she declared, reaching out and stroking his cock lightly to get him ready.

"Alicia, please," groaned her brother, as she used her tongue to moisten John's cock.

John never had been tit-fucked before, but he had an idea of what it would be like from watching it done on porn. 'I wish her spit worked really well as a lubricant. And while we're at it, double the size of my dick.'

"Do you--" the voice managed before John practically shouted, "Yes!"

While Alicia's hands continued slathering his shaft to ready it, but suddenly it grew soft. "huh? What just happened?" asked ALicia, a little confused.

"Keep going," John demanded. "Use your breasts!"

"Hmmmm. You got it. My big fuckin' titties'll get you going again," she replied as she took his rapidly re-hardening dick and placed it in her cavernous cleavage.

She massaged his dick between her massive jugs, their firmness transferring a great deal of the motion directly into his stiffening dick. It reached maximum hardness, thickening to over three inches across while Alicia smiled.

"You're getting really hard. I can't wait to see how much cum you have for me. Ooohhh! What's that I see peeking out the top?"

At almost a foot , Little John was long enough for Alicia to treat most of it to her jumbo boobs while her lips and tongue enthusiastically pleasured the remainder. The friction seemed to be getting her off almost as much, because she couldn't stop writhing.

Eli had long since given up and gone to his room to whack off. Maybe it was time to....
