I was snapped from my reminiscing, by a slight squeeze on my nuts. Tina was looking up at me with a gleam in her eye. but she never stopped what she was doing. Then came the point of no return. My cock enlarging slightly,and my nuts sucking up. Tina withdrew so that only my cock head was in her mouth, and started pumping my shaft. My hot load bubbled up from my nuts blasting deep into her throat. She began dutifully swallowing shot after shot of my cum. I was euphoric with pleasure.
I simply had to return the favour. I grabbed Tina's legs and flipped her onto her back. Tina giggled in anticipation of what was to come. I started by kissing Tina deeply, then moving to her neck, then collarbone. I continued to kiss Tina down her body, I paused briefly at her twin peaks, sucking gently of each nipple. Down across her flat stomach, before finally reaching her bare mound. I breathed deeply of her womanly scent. I glanced up at Tina, who had her eyes closed in anticipation. Seeing that I smile to myself, and attack her clit in full force.
My sister screams from the shock, as I suck her clit into my mouth, and circle it with my tongue. Tina starts emitting deep moans of pleasure, from the mounting fiery passion in the very essence of her being. Letting her clit go I probed her lips with my tongue, tasting everything. I fucked her with my tongue as her juices started to really flow. Then I easily slid first one then a second finger deep into her and started to furiously finger fuck her. Tina started to squirm, and her breathing rapidly increased.
Sensing that she was close I renewed my attack on her clit. I sucked it back into my mouth and hummed, sending her over the top. I clamped my mouth over her pussy and continued to stimulate her with my tongue, as I drank her fluids. Tina clamped her legs around my head, as she thrashed all over the bed; almost breaking my neck in the process. I started to slow my assault to allow her to come down from the violent orgasm that had ripped through her body.
