She stared at me, her face inches from mine. ‘Oh…Yeah…Ooooo, Andy, fuck me with that big cock….Oh, it’s so big…it’s so good…Oh….that’s it…Ever since I saw it…saw Jill sucking it…I had to have it in me….Uhhh…I had to fuck you…’ I was matching her thrust for thrust; her ass was moving like a jackhammer. My hands found her hardened nipples and pinched them hard. ‘Aauughh!! Ooooh, yeah baby…Fuck…fuck…FUCK…’
Suddenly the lights snapped on. ‘You two better keep it down before you wake Mom and Dad.’
It was Jill.
She was standing in the doorway at the bottom of the stairs with her arms crossed, looking at us very disapprovingly. Jenna and I froze like 2 sexy statues; My dick began shrinking instantly.
She smiled. ‘Oh, don’t stop on my accout; the cat’s out of the bag now, might as well go with it…’ She stepped into the room. ‘Go ahead.’
Jenna’s stared in shocked disbeleif as she watched her big sister walk over to the couch and stood just a few feet away from us. Jen looked up at me, the scared little sister asking her big brother what to do. I was totally dumbfounded. As my dick rapidly diminished inside Jenna’s puss, I looked sheepishly up at Jill and said, ‘Um…this is really…she…we’re…’
Jill looked very seriously down at us and replied, ‘Andy, really; go ahead. I want to watch. Fuck her.’ Jenna looked at her sister, smiled, and looked back at me. She started moving again and guided my almost-but-not-quite limp dick back into her cunt. She moved her hips back and forth until I felt the blood rushing back to my cock. Jill watched intently as we resumed our fucking. My little sister bounced up and down on my dick with renewed fervor. Soon we had resumed our previous rythm. Jen began grunting with every in-stroke.
‘Yeah, that’s right,’ Jill breathed. At first, I sort of felt ‘on display’; I’d never had sex in front of anyone before. ‘Yeah, Jen, fuck him…fuck his big fat cock…’ Her words spurred me on. As my big sister watched me and my little sister fuck, I became more turned on than ever. Jill looked on with an evil look as we slammed away at each other. Jill took a few steps back to take everything in and then began stripping out of her clothes. She kicked off her shoes, unbuttoned her blouse and slipped out of it. As I watched her removing her black bra, revealing her beautiful tits, our eyes met and I reached a level of sexual excitement that I never dreamed existed. Still furiously fucking my baby sister, who was making increasingly intensifying animal noises in my ear, I watched as Jill stepped out of her jeans and removed her pink panties. Jenna looked over at her older sister, now completely nude, and came intensely with a thunderous groan. She squeezed my neck so tightly I thought she’d break my back. When the tremors subsided, she grabbed my face between her hands and we kissed passionately; I slowed my upward strokes considerably and we made out for a few minutes, Jill’s hungry eyes on us all the while. I didn’t want to stop but Jenna gave me a gentle kiss and rolled off of me. My hard dick slid out of her hole with a nearly audible ‘pop’. ‘Jill he’s so good,’ Jenna said dreamily. ‘It’s so fucking big…’ She leaned towards me and kissed me on the lips again. She gazed over at Jill, now seated on the arm of the couch behind me. I stil wasn’t sure what Jill was up for; watching or participating; so I figured I’d follow their lead.
‘So were you really awake all those times?’ she asked, her eyes flitting between mine and my still swollen member at Jen’s side.
