Helen's lips held my black shaft as though it was her tight cunt sliding up and down my cock, at the same time her tongue teased me, taking me to the edge time and time again. My wonderful sister had obviously used her time at college to good effect. She knew just when to relax her grip and when to stop sucking for a moment or two. How many cocks had she blown to hone that skill I wondered as once again my sister's mouth took all of my cock. I pulled a pillow under my head to better give my sister's juicy cunt the same pleasures she was giving me.
Helen raised herself so that she was almost sitting on my face. She squirmed, pushing her pussy against my lips and tongue. My sister sighed as I found her clitoris, Helen's sensitive love bud. She shivered and sat up straight, I could hardly breathe as her grinding on my face intensified. Taking gasps of air while trying to swallow Helen's copious juices without drowning, I reached up and found her nipples. She shook in the throes of her orgasm. Her moans were interspersed with mutterings of "My brother, my brother, my brother" before she collapsed back onto me.
I rolled my horny sister onto her back, still in the soixante-neuf position, so that I was now on top. She took me in her hand and lapped at my glans, slowly at first, savouring the precum I was oozing, then she fed me over her lips. I could do nothing but begin to thrust, fucking her mouth. Helen's arms locked my legs in place. She arched, effectively presenting her pussy once again to my mouth. A slow steady rhythm, at once fucking my sister's mouth and eating her cunt. I felt Helen spasm again under my tongue as her second orgasm took hold. I couldn't hold back. My cock twitched. I tried to pull out of her mouth. She clamped my legs tighter. I stopped struggling and let the contents of my sac pump down her throat. She released her hold on my legs as she struggled to swallow it all. I rolled onto my back.
"So much, so soon after last night big brother."
Helen smiled sweetly, somewhat coyly, and disappeared to the bathroom. On her return she cuddled at my side, her head on my chest. She idly played with my chest hair while I ran my fingers through her golden locks. There is something very sexy about blonde hair sliding through black hands.
I didn't know what Helen was thinking but I for one didn't want our illicit coupling to stop. My baby sister was the best fuck I'd ever had. That we were half siblings made no difference, what we were doing was taboo, but it felt so right. Helen had moved her hand from my chest and was cupping my balls. My cock twitched back to life. She stroked her nails up the length of my manhood. I was fully hard again. Helen turned onto her back and opened her legs. I didn't an invitation. I climbed between her legs and entered her, it was so natural, my throbbing cock in my sister's cunt.
We made love slowly, gently, telling each other how much we loved each other.
