During our walk from the park to the train station, I could not believe what I had just agreed to: I was taking my brother back to my apartment for sexual release of some sort or another. I was not sure what form that release would take. But, I promised myself that this would be the last time.
I told myself: "I am Jack's older sister. I'm supposed to be the mature one. I'm not supposed to do this." Nevertheless, I couldn't help but admit that I was more turned on than I had been in a long time. It was the wrongness of it that was making my pussy tingle.
On the train back to our neighborhood, Jack and I got seats next to each other. Jack began stroking my thigh. I don't know why, but this simple act was making me short of breath. The further up my leg Jack's hand wandered, the shallower my breathing became.
When the train went into a tunnel, the lights went off. Jack profited from the sudden darkness to trace with his finger the outline of my slit through my jeans. I couldn't stop myself from uttering a moan of surprise and delight.
While the lights were still out, I grabbed for Jack's big boy. It was easy to find in his pants as it was large and swollen. I gave the bulb a squeeze, and it was Jack's turn to moan. We both removed our hands just as the lights came back on.
The train ride home was interminable. I was aching for Jack. I knew it was not right. But, that made it all the more delicious.
The walk home from the train station was agonizing. Jack kept trying to pin me up against a wall, a tree, a fence, etc. On each attempt, I could feel his big bulge. Jack tried to kiss me. I drew the line there and told him that this was one thing that siblings cannot do. I also worried that someone I knew would see us.
We barely made it in the door. Jack ripped my t-shirt over my head. He didn't bother to unfasten my bra. He simply pulled it up over my aching breasts and yanked it over my head. Before I knew what hit me, my brother was going to work once again on my nipples with his lips and tongue. Every once in a while he would also gently bite my brown wonders with his teeth. This sent me through the roof. I could feel my panties getting very moist.
While Jack continued his loving assault on my boobs, I gripped his boner through his pants. I then fumbled with his belt buckle, button and fly. I couldn't get his pants down because my brother refused to give up his lip-lock on my swollen tits.
"Jack," I panted, completely out of breath. "Let's go over the couch." Jack nodded and grunted. He peeled off his pants and briefs, leaving them in a pile on the floor.
"Sit down, honey," I said with authority. I sat next to him and began working my fingers up and down the length of his pulsing staff. His dick felt so good in my hands. Meanwhile, Jack began kissing my neck and tried to kiss my open mouth. I stopped him by pushing his head back down to my hooters which were still crying for attention.
I had one hand at the base of Jack's penis and the other up just below the head. I applied loving ministrations. The head of the beast was an angry, purple color. I was jacking Jack.
"You like me stroking your cock, little brother, don't you?" I asked in a playful bad-girl voice.
Jack grunted with my nipple in his mouth.
"Are you gonna' come for your big sister?" I asked.
Before I knew what had happened, Jack lifted me up and threw my body lengthwise across the couch. He spread my legs and jumped on top of me. He began to grind his crotch into mine in a furious manner. It felt so good.
Jack stopped and reached down to my jeans. Before I could protest, he had unsnapped them and was pulling them off my legs. He got them off rather easily and was reaching for my panties when I shouted: "No Jack. We can't do that. We can't fuck." Although he was clearly crazed with lust, Jack stopped.
"What do you mean? I need you," he said.
I replied, "I know, honey. But, you can't put your penis in my vagina. That we can never do." He looked at me expectantly. I continued, "But, there are a lot of other things we can do for each other, baby."
Jack smiled down at me. There I was, lying on the couch with my legs spread wide apart, wearing only my little striped panties. My brother crouched above me with a raging boner.
He looked unbelievably good. Army physical fitness training had done wonders to help Jack to shed the little bit of baby fat he had possessed when he entered the service. His chest and abs looked sculpted.
Jack extended his hand. I looked down at my pelvic area and saw the target of his reach. My panties had a big wet spot at the site of my dripping cunt. Jack looked at me as if waiting for approval.
I nodded my head vigorously. Jack touched my crotch with his finger and it felt like an electric shock. I moaned loudly. He then began to massage my little baby through the thin material of my panties. Bliss.
After rubbing me for a little while, Jack said softly, "Why don't we take these off?"
