“Oh shit” Steve cried out and I turned to see him pushing Mary’s head down on his cock as his hips bucked wildly.
Mary made a gurgling sound and as she drove her mouth down on his cock I saw a line of cum drool out of her mouth and down his shaft. At that moment Alicia gave my balls a squeeze.
“Oh fuck sis!” I called out as my cock went off in my sister’s mouth.
Alicia moaned and her blue eyes rolled back as she continued to suck. My hips jerked as my cock erupted sending a series of long streams of cum down her throat. She made a wet gurgling noise similar to Mary and as good as Alicia looked sucking, I looked over to see Mary cleaning the spilled cum from Steve’s cock with her tongue. I quickly went back to Alicia who was now sucking hard on my cock trying to completely drain it if every drop. I made another of those pathetic sounds as she squeezed the base and I felt a couple of more drops ooze from my dick and into her mouth.
“Oh fuck.” I moaned.
Sliding her mouth from my cock, Alicia stuck her tongue out and waggled it at me. It was covered in cum and turning her head she showed it to Steve and Mary. With a nasty smile, Mary stuck her own white dripping tongue to us before slurping it back in her mouth.
“Jesus.” Steve said softly, “Talk about audience participation.”
“I couldn’t resist.” Mary said, sitting up.
Looking at us she wiped at her mouth then said, “Well Andrew I think your sister deserves a treat for that don’t you?”
“Yes ma’am!” I exclaimed and for the first time moved with no hesitation
Standing up so quickly my still hard cock slapped Alicia in the face; I grabbed her by the shoulders and yanked her to her feet. She released a startled yelp as spinning her around me literally threw her on the bed.
“Oh yeah!” Steve clapped, “Little brother has the fever now!”
Alicia began to laugh, but it changed to a loud moan as kneeling between her legs I all but dove into her pussy. I spread her lips wide and immediately plunged my tongue into her hot little box.
“Yes!” she cried out, “Suck your sister’s pussy!”
I swirled my tongue around inside of her, reveling in the taste of my sister’s juices. As my tongue probed her sweet hole I took a deep breath and moaned at the scent of her pussy. Her flesh was wet and hot against my face and I started moving my head, working my rigid tongue back and forth.
“Yeah, tongue fuck me!” Alicia moaned, “Show me how bad you want it!”
“Hearing that makes me want it!” Steve declared.
I sensed movement and heard Mary release a long loud moan. Turning my head slightly I saw that Mary was now laying against the end of the couch with one leg across the top and one foot on the floor. Steve was kneeling on the floor licking her pussy as she spread it open. His head was leaning against her thigh and even as his tongue lid up and down her red haired pussy his eyes were on us.
My still hard cock jumped between my legs and returning my attention to my big sister’s delicious snatch, slowly trailed my tongue through the wet folds of her pink flesh.
