Brother-In-Law Late Night Visit

I am the youngest of 3 daughters. My two older sisters, 10 and 8 years older, are great sisters. I had just completed my sophomore year at college and both of my married sisters, their husbands and children came home to for Christmas. It was a great time and, as usual I flirted and had fun with my brother-in-laws who I thought were more like brothers than just guys. They teased and flirted back and my sisters played too. Everyone thought it was great we all got along.
After a Christmas filled with alcohol, fun and food I went to bed late. Apparently, my brother-in-laws stayed up late drinking and playing pool with my father. Around 1:45 someone walked into my room and proceeded to use the bathroom off my room. It was dark but from the sound of the peeing, it was a male that had a full bladder. I dozed back off but was awaken as someone sat on the edge of my bed. Just as I was about to rollover and inquire, I felt an arm go around me and someone snuggled up close to me in the spoon position. I was wearing a tee-shirt and panties. I quickly realized that my bed partner was nude. I felt my heart race as they snuggled close and a hand found my left breast and gently squeezed. I almost screamed but nothing came out. I felt a penis stiffen against my ass as they continued to massage my b-cup breasts and tweak my nipples through my tee shirt.
I am much more athletic than my sisters. My size 2 body and b-cup breasts fail to compare to their mature size six or eight bodies with large c or d cup breasts which make my breasts look like mosquito bites.
A soft warm hand traveled up my shirt and was soon caressing my bare breast and I felt a large penis begin humping the crack of my ass giving me a wedgie. I was getting too turned on to stop what was happening and soon I smelled alcohol tainted breath as they kissed my neck.
I was slowly rolled over and, as he peeled my shirt off, I realized my very drunk bed partner was my oldest sisters husband Tim. At 33, Tim was handsome and very fit as compared to what I would have imagined. We kissed and soon he was sucking on my breasts and rubbing my crotch through my panties. I was not a virgin but I had not had sex in over a year following a bad relationship where I caught my boyfriend in bed with my college room mate. Tim was handsome and I soon realized that the size of his penis was extremely large and disproportionate to his body size.
Just as I started to stop this craziness, his fingers slipped into my panties and into my kitty. Although I keep it trimmed, I have a very hairy bush that he instantly appreciated and purred in my ear. As his finger slid into me I reached down and wrapped my hand around his very long and hard penis. Our tongues clashed and I tasted his alcohol ridden breath as we kissed. I came quickly on his fingers and bit his tongue by accident. He yelped but quickly continued to kiss me and then kissed down to my breasts. As he kissed my breasts he tugged at my panties. I tried to resist, more mental than physical, but quickly relented and lifted my hips so he could slide my panties off.
We repositioned and Tim and I embraced and kissed. His warm soft, almost hairless, skin felt great against me. He kissed down my neck and chest. As he kissed down my abdomen, I realized where this was going but I had no desire to stop him. Although I knew that Tim tasting my womanhood was way beyond anything that anyone would consider appropriate, I wanted to experience a man tasting my womanhood for the first time. I guess I told myself that Tim was safe and it would be just our secret.
I orgasmed quickly as his tongue and lips tasted me and I pulled his head tightly against my kitty. I held back screams and my chest heaved as I gasped for breath.
What happened next was expected but I tried to think I should have stopped him.
Tim kissed his way up my body. I raised my knees and spread my thighs as he kissed me and I tasted myself on his lips. I felt him guide the swollen head of his penis to the swollen wet lips of my pussy. I gasped as he pushed his hips down and I felt his large penis stretch the lips of my womanhood open as he began to slide his large-thick manhood into my tight kitty.
Tim groaned, "oh god you are so tight tonight baby" as he began to fuck me. OMG, I couldn't believe I was having sex with my sister's husband. I wanted to stop but I couldn't. His large penis was stretching me and he was pushing deep into me.
I moaned as he picked up the pace and slammed down into me. He pulled me tight and pushed hard. I wasn't quick enough to realize that he was at the point of no return but he was.
I felt his body twitch and his penis pulse. Just after he made a grunting noise I felt a warm flood deep in my womb as his penis continued to twitch. He humped even deeper into me and moaned in my ear as he filled me with thick of cum.
I am such a bad sister.
After he passed out, I dressed and climbed into bed with my sister.
