I went to college in California. Lisa also went to school here, but lived on campus. When I got out here, I got a roommate and got this great apartment under rent control. Just lucked into it. Lisa was still in college but not near me. We didn’t have a chance to see each other that often. I was getting older now and my feelings for my sister had changed. I was ashamed of the episodes of pawing after her and chasing her around amusement parks lustily.
I wanted to make it up to her. I knew then that it wasn’t right but she was so close all the time, that I let her good looks cloud my young judgment. Anyway, now, I had a girlfriend. My roommate had introduced me to this classmate of his. She was nice looking with brown shoulder length hair, an athletic build, and smart. She even wore glasses.
She was the first girl to ever pay me any kind of prolonged attention and I liked her a lot. I was doing good -well, I was doing ok in school and our apt. was close to the beach.
Everything was fine. Then……Lisa showed up. I knew she was going to stop by. We had arranged it the week before. I had not seen her in a long time, though, and I kind of missed her. I wanted her to meet my girlfriend and my roommate. My roommate was this tall skinny guy I took English lit with named Keith. (not his real name) Keith comes and knocks on my bedroom door and says, **“Man there is this HOTTY at the front door looking for you- Dude, I thought you had a girlfriend**.**”**
A hotty?! Wow! I got excited as I got off my bed, then I realized it was probably my sister. I didn’t know how to feel. I still felt embarrassed whenever I saw Lisa. The time we spent apart I thought she’d think I was using to fantasize about her, and I wasn’t. I put on a shirt to go out to the living room and to the door. There she was. And of course, she was wearing a tight, white spandex stretch top. Has this woman ever heard of a jacket? This doesn’t help my convictions, I thought. She smiled when she saw me and rushed toward me yelling **“MacArthur!”** I smiled my creepy smile, cause I knew
I was about to get a blast from her superb chest. Her jugs bounced toward me straining in that top and it was all I could do to keep my eyes on her face and off her body. Then—Juushz!! Lisa’s boobs plopped into me with a force that was at once soft and firm. I embraced her hotly. Fuck my convictions, i thought. I would never frigging let this go again.
“**I missed you sooooo much!”** she was saying. Who was listening? I was concentrating on keeping my boner a secret from her. Now, I’d had dates with girls in college, and even a steady, but none of them got my rock harder faster than my own sister. Lisa pulled back a little and further gave me masturbation fodder when she took my head in her hands and smooched me on the Mouth!! **“Smack!”** it wasn’t sexual on her part, but I could now demolish a Volkswagen with my dong. **“How are you?”** she continued. **“Ahem”** Keith had stood by idly for moments but wanted an introduction and was now clearing his throat. Lisa turned toward him and said, **“Hi, I’m Lisa, I’m Mac’s sister”** she stuck out her hand for him to shake. To my surprise, He said to her-and the balls it took to go here- **“Hey, any sister of my roomie is a buddy of mine”** and with that, he extended both of his arms toward her indicating he wanted a hug, and stepped toward her. Lisa was game to share her charms, she warmly hugged Keith while I looked on, getting jealous of course. No longer ashamed at ogling and pawing my sister in the past, I now endeavored to continue that behavior, throwing out any notions of ‘Making it Up to Her’ and wanting to grope her all over again. That was the power of Lisa’s body. You know it’s wrong, but fuck it, you’re headed there.
After catching up, we all decided to go out to a local bar scene. Lisa and I had never really been out drinking together, and man, did I regret that. She is crazy when she lite’s up. That’s right, she shakes ‘em too. Every guy in that bar tried to dance with her. They were puttin’ on slow songs, too, the creeps. She politely declined them all except Keith, who she seemed to kind of take a liking too. (don’t worry, I wouldn’t let him near her) We had drank a lot, and I saw it was only 7. That’s when i remembered that I had a guy coming over to see the apt. At 7. You see, I was looking for a new roommate because Keith was graduating and going back to live with his parents. I persuaded them to leave the bar and come back to the pad with me. When we got back, a guy was waiting outside next to a motorcycle. ‘**Shit’** I said aloud***. ‘*****this must be the guy, Keith,’ “What guy?”** said Lisa. ‘**The dude that answered my ad for a roomie.’** Saying that aloud was a -how do you say it in this country? Ahh yes, -A big Fucking Mistake! **“Whaaat !!?”** shouted Lisa, clearly drunk. By now, we had approached the guy and I stopped talking to my sister and apologized to the guy for being 10 minutes late. **“Don’t sweat it, I just got here. Hi my names Eric”** he introduced himself to my companions. We got the door open and stumbled inside. Lisa pulled
me over toward her, and out of earshot of the others said, **“I want to ask you something, c’mere”** I thought she might try this. She wanted to sleep with Keith. I mighta known. Why do the skinny guys get ALL the damn babes? Keith started to show this guy Eric around the apt. Outside, Lisa finally stopped dragging my arm. ‘**What is it!!?’** I said, distracted. **“I thought this was a two bedroom”** Lisa said. **“where’s that guy going to sleep?” ‘What? what guy? Ohhhh. Well, Keith’s moving out in a week’** I informed her. I was glad she only wanted to know the logistics of the three guys, two bedroom problem that college roommates sometimes go thru. I then thought about something odd. I hadn’t looked at her in a sexual way for about an hour. A record for me. Maybe I was growing up. Maybe i was just drunk. She was quiet, so I started to go inside. **“What would you say if I told you I wanted to move in there? i mean Here”** She said. Shit! That totally caught me off-guard. I had to make up something. My mind locked and the seconds ticked by. I’d better say something. Better go with the truth to start. ‘**Uhh-mmm. I don’t know if that would be such a good idea, sis. Besides, I promised my girlfriend that I would let her move in with me if the room ever opened up, and I couldn‘t find anyone.’** I was letting the words pour out as I thought them. I would have been a bad spy. Probably a dead one. Lisa clearly was not buying any of this. She moved in toward me. She was taller than me, and I remembered how much of a bully she was in high school. Was she going to try that crap now? My buzz was still on and the thought occurred to me that wrestling my busty sister would be fun. I could see in her face though, that she seemed to be upset. She blurted out in a drunk stammer; **“I would be better roommate than that guy-or your girlfriend. Where is she anyway?” ‘You’ll meet her tomorrow, Lisa’** I threw at her**. ‘You’d better get some sleep. Go lie down on the couch and I’ll get you some blankets’** Due to the fact that I was becoming a full fledged porno-jockey, paraphernalia in my room and all, Lisa would have to sleep on the couch. Now this is the time the old MacArthur would take advantage of his large-breasted sister. I even fantasized about it while walking to the linen closet. Lisa was tipsy. I could help her get settled on the couch, accidentally put my hands in the wrong places. Rub them across her chest to “adjust her position” on the cushions. But, alas, nowadays, while those thoughts occur to me, I know it is morally wrong and abusive and would not be fair to a young woman -oh who the hell am I kidding? if there weren’t two other guys walking around the place, I would have probably tried to molest my sister right there in the damn hallway. There I said it. And now she wants to live here? With Me? Alone? At any rate, when I returned to the couch with the blankets, Lisa seemed out for the night. Keith and Eric were talking by the door. I went over, shook Eric’s hand and apologized for not showing him the place personally. **“No problem. Man, this is a cool spot. I can smell the ocean, and the price is great. How soon will you decide?” ‘Ah, in the next coupl’a days actually. I’ll let you know. Thanks for coming by man’*****.*** After he left, Keith turned around and said, **“What’d Lisa want with you, anyway?” ‘Oh, uh, family stuff’** I lied. We both looked at her passed out on the couch. The blanket was not covering any part of her that mattered. Her bosom dramatically- well maybe not dramatically, but steadily rose and fell as she slumbered. Magnificent in that spandex top. **“That guy Eric seems like a cool dude.”** Keith said. I agreed. **“Yeah”** to myself, I thought; too bad…the guy never had a chance.
