Tried Docking

I spent the evening with my sister and husband.

Thanks to my swinger sister asking me, I had the chance to dock cocks with her husband. Being very curious, I decided to give it a try. If I'm going to have sex with a guy, it might as well be my brother-in-law than some stranger.

A few days later I went over to there apartment. My very sexy sister answered the door in her little blue panty girdle and bra, giving me a tight hug and a very sensual kiss on the lips. We had kissed before but never like this. Her body felt so firm and petite as I ran my hands over her cute little butt.

My sister led me into the living room where her husband was sitting. He was wearing boxers and a t-shirt. We sat and talked for awhile about nothing special. Occasionally he would slowly stroke his erect cock looking directly at me. He was apparently anxious to get started.

After a few minutes, my sister suggested I should get undressed. I stood and she helped me strip down to my underwear. When my pants hit the floor, she wrapped her hand around my hard cock and said, "Oh! Looks like your looking forward to docking with my husband." I agreed and my brother-in-law stood and lowered his boxers.

My sister had always said he had a perfect cock and she was right. Looked to be maybe a little more than 6 inches, and nice average girth. A little bigger than mine in both respects.

My sister pulled my underwear down exposing my manhood to her for the first time in many years. She gently stroked me with the tips of her fingers, making shivers go up my spine. "Okay you studs, let's get your beautiful cocks connected together."

She brought our erections together. When the tips of our cocks touched I felt extremely excited and became as erect as I've ever been in my life. I mean I was hard as a rock and I could feel my heartbeat in my cock. Then my partner, began pulling his foreskin over the head of my cock and down the shaft an inch or so. His foreskin fit snugly over my cock and it felt absolutely amazing. In just a moment the mushroom head of our cocks were being held together by his generous foreskin. Our cocks had become one cock, going from his body to mine. I wondered if I ejaculated hard enough, would my sperm be forced into his balls. It sure looked like it could. Oh my god, this felt so amazing. I never thought I'd ever be connected to another man sexually, but here I am and I'm loving it.

The whole time my sister is standing next to us watching intently. Suddenly she begins making out with her husband and asked him if it felt good. He replied, "Yes very nice." Then she got on her knees and started licking both our cocks while fondling our balls. This went on for awhile, occasionally pulling her husband's foreskin down my shaft a little further keeping us firmly tied together. I couldn't believe what my sister was doing. But seeing her enjoying our docked cocks was so erotic.

After a few minutes she stood and whispered something into her husband's ear. I couldn't hear what she said, but he quickly replied, "If that's what you really want, then just do it." She kissed him and went back to her knees.

Slowly she rolled her husband's foreskin back releasing my cock from its grip. There was plenty of precum dripping. Obviously we were both very aroused by what we were doing and what we felt.

Then to my surprise, my sister took my cock into her mouth sucking it vigorously. I immediately looked up at my brother-in-law to see his reaction. He obviously understood my surprise and nodded yes and smiled as he stroked himself. Then he looked down at his wife sucking cock with her tightly girdled butt pointing towards him.

I knew what he was thinking. I was soon going to be watching my sister having intercourse with her husband. Sure enough, he knelt behind her, took hold of her girdles waist band and peeled it down her body to her knees. Then he positioned his cock at her pussy opening and slowly inserted himself into my sister. She moaned as she took him into her body but never stopped sucking on me.

Seeing my sister having sex was without question very arousing to say the least. Seeing his cock going in and out of her was very special. I couldn't imagine what it must feel like for him.

My sister stopped sucking me when she felt herself building up to a orgasm. And then she let go with a huge moan and her body began convulsing uncontrollably. Her climax was incredibly strong and long lasting. As it began to subside, she looked up at me with tears in her eyes unable to speak.

After a few moments she was barely able to speak enough to say, "Bro, I want you to fuck me now!" "What sis?" "I want you to fuck me with your cock, now!" I looked at her husband and he was pulling her girdle the rest of the way off. Then he moved to the side. "You better fuck her before she changes her mind."

I positioned myself behind my sister and mounted her. My precum dripping cock easily slid inside her little wet and warm pussy. As I looked down I couldn't believe I was balls deep in my sister. She felt so wonderful wrapped around my cock I couldn't resist fucking her hard.

After a few strokes she had an orgasm but not as strong as she had with her husband. As I fucked her I felt myself beginning to loose control. Fucking my sister was just so unbelievably erotic. It's so different from having sex with any one else. All I could think about was, I'm fucking my sister and she going to get my sperm deep inside her. If you ever get the chance to have sex with your sister don't hesitate to do it. You won't regret it.

Then it happened with much intensity. I ejaculated millions of sperm into her pussy with each thrust. I erupted at least 10 or 15 times before I was drained. Holy shit, I just inseminated my sister with her husband watching.

I didn't want this to end. She laid on her stomach and I laid on her with my cock still in her. Surprisingly I was staying hard, at least for now. I whispered in her ear, "I love you so much sis. That was amazing, thank you."

She wiggled her butt gradually working me out of her. I rolled off and laid next to my sister. "Bro, your going to be fucking me often from now on. I need you and I love you too." We kissed deeply with our tongues mingling.

My sister rested while her husband and myself docked our cocks again. We laid on the bed facing one another with our cocks connected for nearly an hour. Eventually he orgasmed filling his foreskin with cum. The head of my cock was covered in his sperm. It felt incredible as I watched him ejaculate.

What an amazing experience! Can't wait to have intercourse with my sister again.
