” I pulled his cock rhythmically.“So nice. I want to taste it.” He grunted loudly in response.“Oh, baby, your cock is so warm...and hard. I want you to come soI can taste you. It’s so warm…so hard…so alive…Why, I canfeel the b***d just throbbing in it!” “And the come…building up…” he added, trying to keep hisvoice steady. “Yes, that too. Come building up…I want it to build upand build up and build. He found my swollen bud and slid his fingers beneath my panties. He pushed them inside me; I moaned so loud. “Oh Jesus, fuck!” My body writhed and squirmed beneath his touch. I was close and there was no stopping the inevitable. His fingers probed deeper and harder. With his tongue still pushing through the material of my panties, he hummed against my throbbing nub. My screams poured out, as I shook and trembled my way to climax. The warm gush of fluid that signalled my orgasm rushed out of. " But, just as the words had finished rolling off my tongue, my sister was in the open doorway, wearing nothing but a tiny towel around her waist. Her big, firm tits were right in front of me for me to feast my eyes on, but I couldn't do that to my sister."I wouldn't do that brother, I made sure I saved you at least one drop.

With one powerful thrust he impaled her on his rod giving her a moment to catch her breath as she exhaled a loud and long moan. He wasted no time continuing his ministrations, pulling back to her opening and pushing back. Starting with quick deep strokes he gradually stopped shorter and shorter making his thrusts shallower and shallower. He felt teeth hit his finger more and more as she began losing full control of her mouth muscles. He pulled his finger out of her mouth and ran the saliva.
