I got up in the middle of the night and went out to check on Lisa. She was awake, curse my luck. When we were living at home I would sometimes try to catch her sleeping. When she slept on her back, her jugs were always moving around. One night I watched her twist and turn for an hour on our couch. She was just beautiful. I moved in daring myself to touch one or both of her orbs. I crawled over on my knees, pretending to watch TV, and got very close to her. Her mouth was slightly open and she was breathing evenly. I chickened out, though. You just couldn’t tell whether she was awake or not. Or if i pressed my lips against hers if she would Then wake up and slug me. I still fantasize about it. I could have probably kneaded her tits like bread dough and she would have thought she was only dreaming. She was however, at present, just sitting on the couch. ‘What’re you doing still up?’ I asked.
The TV was off. “I’m thinking. I think i want to move in with you, Mac. I’ve been trying to figure out a way to do it.” **This** again. ‘Listen, Lisa, I made a promise to my girlfriend that she could move in here.’ I was lying badly now. ‘It’s closer to the campus’ Lisa stood up and walked toward me. “So why are you showing the place to some frat-boy?” I paused to answer. ‘Leese, there are no fraternities here….’ “Well, You know I’ll find out if you’re lying to me…” She went on. I tilted my head down to hide the fact that I just took a hard swallow. She gave me a skeptical look. “When am I going to meet ‘Brenda’?” She interrogated ‘Uh, she’s picking me up for school tomorrow. She gives me a ride in.’ “Well I want to talk to her.” She said. ‘Hold on, Lisa, you’re not gonna bother her at all’ I fake stormed out of the room. Now what? if Lisa talked to her, she’d know that Brenda had no desires to move in here. For that matter, she‘d find out I’d never even asked her.
The next morning was bright and sunny. At 7am Brenda came to get me and she met Lisa. They seemed to hit it off which bothered me. I wanted to get Brenda out of the apt. as soon as possible before Lisa questioned her about moving in here. ‘Allright Let’s go’ I yelled from the kitchen table. I got up and went over and grabbed Brenda’s wrist and pulled her away from the she-devil. ‘We’ve got to go’ Brenda yanked her arm back. “Stop it, we have plenty of time” ‘No we don’t’ I argued. ‘But I wanted to stop off first’ Brenda finally relented. “Oh, all right already. Nice meeting you Lisa” “You too” Lisa said while looking right at me. She knew what I was up to. On the way to class, I had a chance to explain why I had been acting strange. Brenda listened and then said. “I think it would be great if she moved in. You should help her out, she’s your family” I thought to myself; Oh really? Then how come I want to get you and her into bed, grease you up with baby oil, and nail you both? After my 4 classes, I caught a ride back with Keith (whom I shared my last class with) We went to the bar and stayed for a while. When we got home, Lisa wasn’t around so I took the opportunity and went straight to my room to lay on my bed and ponder Brenda’s position. She had missed the point. If I lived with Lisa all grown up and all grown out, I would soon want to bang her like a Gong at Chinese New Year. I wouldn’t be able to concentrate on school, that’s even if i got to class. After a few minutes of this ribald thinking, I heard a soft knock at my door. I got up to open it and Lisa came in and sat on the bed. “I’m sorry Mac.” she seemed down.
“I’ve been having a rough time now that I’ll be graduating soon with probably no job.” I sat in a chair across from her. Sitting on the bed with her would start me stammering. ‘I understand’ I said. “Keith’s in the bathroom” She said. She got up and went into my bathroom and closed the door behind her a bit. She turned on the faucet. I peeked in the crack of the bathroom door. I could see her reflection in the mirror. She was taking off her shirt!!! I knew I was gonna get caught now. She had a bra on that was smaller, I think, than it should have been. This was blowing me away. Could she be planning this? Lisa’s tit meat bulged slightly out of the sides and bottom. That’s exactly the way I wanted to see her tits. Pushed together in one of her always-too-small bras. It kind of looked like **>)(<** I slinked back away from the door quietly. After a moment or two, she came out wearing her shirt. “Well, I’m going to bed” she said, and walked to the door. “Leeese..” she stopped and turned toward me. “Yeah?” I was gonna try something here. it might not be anything, It might be subtle, or it might get me punched in the gut. ‘Thanks for not trying to ‘force’ me to change my mind.’ –this was crucial. it required the right response from her –“What do you mean force you?” She asked. How do I broach this, I just wanted her to know how sexy I always thought she was, even though we’re related, but I didn’t want her to think I was the perv I was. ‘You know, like when we were younger and you got me to do whatever you wanted by–, you know, —– charming me’ She put her hands on her hips. “Oh you mean by letting you grope me in malls?” That shocked me. I didn’t think she’d beat me to the punch line so quickly. I didn’t answer right away. I suddenly wanted to disappear. I was embarrassed and wouldn’t speak. Silence followed. I felt a bead of sweat on my forehead. “Would that work?” she suddenly asked quietly, moving towards me. What? What in Hell did she say? The room started to spin. I was instantly afraid. If she was calling my bluff, she would expect me to say no. If I wasn’t bluffing, she might expect me to do something I knew I shouldn’t even be THINKING. Jeezus!, She’s my sister.. “I mean..” She was looking at the ground now. “Is that something that you would Want me to do?” I looked at her face now. I was going for it. I slowly..softly said ‘Seduce me?’… Lisa looked me in the eyes now. “Should I?” She said with confidence knowing the answer. Fuck it. I suddenly strode toward my sister. She braced because she knew i was coming for her. I embraced her powerfully. Squeezing her into me feeling her hot breath in my ears, feeling her big tits mash into my chest. warming me all over. I kissed her neck. I had to go for broke now. she let me and kissed my neck back. Then i pulled her head back cause i was going for her mouth. She was letting me. I pressed my lips into hers and nearly fainted. We weren’t kids now. This was a full grown object of my teenage affection and she was macking with me. that means she didn’t care if i grabbed her ass, which i did. Meaty, like i knew it would be. that means she wouldn’t mind if i pulled her into me and put my hands on her back and made sure her breasts expanded and mashed against my body, which i did.
I was in a weird dreamy- reality state of mind. All my fantasies were staring at me, I KNEW it was happening, but I didn’t really believe it was happening. I didn’t want to make love with her I wanted to Fuck her. Feel her up, bury my face in her chest, grab her ass, kiss her like I kissed my girlfriend when we were alone on elevators. I guess I **did** want make love with her! ‘Leeese’ My breath was hot as I went on.. ‘Sometimes when I see you walking around.. I don’t think of you as my sister, I just think of you as just some….. Honey. I mean if you were anybody else I’d let you move in just because of the way you looked.’ Lisa kissed me warmly and lovingly on the mouth and said “So why does me being your sister change that?….-Look, Mac, if you want, you can think of me as …some foreign exchange stu–” ‘Look it wont matter,’ I charged, ‘I’d still spend the entire time staring at your- ‘ I stopped. i couldn’t keep telling her the same thing. I had just taken me out of a fantasy and dumped me into a reality. Lisa’s eyes grew a little wider. “Staring at what? My tits? So what?” ‘it’s not just that. I mean, fine, i had a crush on my sister. I knew it wouldn’t last, and i became ok with that. I’ll never forget what happened between us….’
“Neither will i Mac” she interrupted. She looked back at me. Again I was quiet. She opened her mouth slightly and stuck her tongue in her cheek, like she was thinking. “Mac…watch” she said after a moment. I looked up at her. **Now get this**: She then took her fists, cupped them over the front of her fun bags and pushed inward, making her boobs swell out of the top of her leotard. She then moved them around slowly, clearly for my benefit, then she quickly let go and her tits bounced up and down before coming back to their normal swaying position. Pong!!! Instant boner. I stared at her in astonishment. ‘Holy fuck that looked great’ I said. ‘Please Do that all the time’ “MacArthur I don’t care if you stare at me. everybody does. You’re my brother and I like being near you. Let me move in. I want us to be together again, like when we were younger.”
To further illustrate the plus side of that, she wiggled her shoulders back and forth which made the top her boobs do a slow dance that would, I swear, make any man out there want to leave his wife and move in with us. I couldn’t take my eyes off her chest, and when I did, my gaze met hers. She seemed to be enjoying the fact that my obsession controlled me. She stepped toward me, but I backed up. I still couldn’t believe this whole thing was happening. I had told the girl I had been in lust with for years, my sister, one of my biggest secrets, and she wasn‘t calling the loony farm for a pickup. Or our father. “Mac, stand still, I was only going to give you a hug.” She lowered her head but held my gaze, “You know you want to hug me.” she said, with a sly look that meant she knew what she was talking about. Then she moved in to embrace me. You are sooo perfect, I thought, and returned the hug. Soooo juicy! She held me loosely but didn’t seem to mind that my hand was in the middle of her back pushing her into me. Then Lisa wrapped both arms tight around my neck and purposely jiggled her rack, bouncing her boobs into me. Fuck. She had me. She knew she had me. And she knew that I knew. Her boobs swelled into my chest. Like heavy, oversized water balloons that swayed to and fro against me. I kissed her like she was Sophia Loren. Thick smooches and smacks as she held me tight again. She softly hummed an evil laugh into my ear. My boner pressed into her upper thigh. She MUST feel it. “Yeah, I feel that” She said as if she could read my mind. I didn’t care. I was being seduced. We both knew it. I think the best part about it was that she KNEW I couldn’t resist her. This would have to be the way she settled any disagreements we had while living here, and I was fiiiiine with it.
