Staying in.

'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, but said simply: "OK." She smiled and pirouetted, posing to show off her assets.

As the girl spun, her brother looked over. "Yeah John? Oh, I guess I should give you something to help out," he replied, handing John a 20 and not giving Alicia a second glance. He looked back down at his book. "Now, you two get going. I've really got to get some studying done, or I'll die on the next test."

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

"Uh? Huh! Ssstop thaaaa! Oh! Oohhhhh. Oooooohhh! John. Yes. Please. More." She mewled, pressing herself into John's hands. Her own came up to try to hold his in position. John lifted Alicia's tee shirt up over her head and dropped it on the ground, exposing her breats around the ruins of her bra, which he quickly stripped off. Alicia's hands replaced his on her chest. She looked dazed as John put his hands on her shoulders and gently lowered her to her knees. She looked puzzled for a second, then giggled and 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. John looked over and saw Eli continuing to study, but not the least bit concerned or even paying attention to the fact that his sister was about to felate his roomie not three feet away. Alicia lost patience with John's distraction and tugged John's pants and underwear down to his knees, grabbing his cock and kissing the tip.

"Use your tits," he told her. "Oh yeah. 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, something that was hardly necessary at this point. John never had been tit-fucked before, but he had an idea of what it would be like from watching it done on porn. 'Can't disappoint my fans', he thought. 'double the size of my dick, would you?' he requested and quickly confirmed.

While Alicia's hands continued working his shaft and she was just about to put it her breasts to work when suddenly it grew a lot softer. "h=Huh? What just happened?" asked Alicia, a little confused, her actions slowing slightly.

"Keep going," John demanded, feeling only half staff, but loving her hands working him. "Come on, use your breasts!" he added.

"Hmmmm. You got it. My big fuckin' titties'll get you going again," she replied, noticing that his dick was getting even bigger under her ministrations. She took his rapidly re-hardening dick and placed it in her cavernous cleavage, massaging it 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. 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 , John's Penis was long enough for Alicia to treat most of it to her jumbo boobs while her lips and tongue enthusiastically pleasured the head. The friction seemed to be getting her off almost as much as she was getting John off, because she couldn't stop writhing.

Eli continued studying. The moans were a bit annoying, but not bad enough to be really distracting. He still kind of wished they would leave, but it was John's room too, and at least Alicia looked like she was having fun.
