“Have you ever fucked him?’ Jenna abruptly asked.
Jill shot her a look as my dick popped out of her mouth. ‘No way! That would be cheating on Mark!’
‘And this isn’t?’
‘SHSHSH!! No! It’s just oral sex! And besides, it’s not like this is another guy; he’s my brother! And he doesn’t even know. C’mon! Be quiet and let me finish. I told you you could watch only if you were quiet.’
Jenna’s questions stopped. Jill concentrated on my member, blowing me just like the night before. My sister’s warm mouth felt phenominal. I started moaning and writhing; Jill didn’t stop and Jenna leaned in for a closer look. She leaned forward in the chair with one hand pushed into her crotch. ‘Ohhh, yeah, he likes it,’ Jenna whispered. “Suck it, Jill. Yeah, suck Andy’s cock.’ The hand in Jenna’s lap started to move. She began masturbating her 18 year old pussy through her pjs. ‘Suck that big dick.’
Jenna’s hot talk seemed to heat things up for both of us. Jill sucked me harder and deeper and I felt the jizz rising. Peeking out from under one eyelid, I watched as Jenna pulled the crotch of her pajama shorts over to one side, exposing her cunt. The hall light shone through my open door and spilled over the chair she sat squirming in, illuminating her pretty pink pussy. I didn’t get much of a look, though, as her other hand started quickly rubbing the exposed mound of her cunt. ‘Suck his big hard dick Jill. Suck it for me.’ An animal look crossed her face as she played with herself and watched Jill inhale my long, fat prick…I caught sight of Jenna sliding a finger into her pussy and finger fucking herrself…This was just too much for me. The cum was ready to blow and Jill knew it would gush any second. She let out a series of moans as my hips fucked her face, ‘mmm, Mmm, MMM!’ and I let flow another throatful of thick, hot cum. Jenna watched, writhing in the chair, her hand slapping at her wet mound as Jill swallowed all of my load hungrily. I spied Jen biting her lip and shaking to orgasm, grinding her finger into her puss. I let out a loud “Ohhh!” and they both froze momentarily; but I just smiled and rolled over.
I couldn’t see either one any more, but I heard Jill say ‘See? That’s the fourth time I’ve sucked him off and he has no idea! It’s great! I can get off while I’m here and it’s like…no harm done!’ Jen lay back in the chair, panting. Jill looked down at her baby sister’s still-exposed cunt. ‘Wow. You really get off on that…’ Jill said, as Jen slowly straightened her pj’s.
I’m assuming Jenna nodded her head in the affirmative. ‘But how do you get off? Just by sucking his dick?’ she asked.
‘No, I sometimes play with myself while I do it; sometimes after when I’m in my room.’ Jill replied as she slowly got up off the bed.
‘Well, I’m wondering…If it’s okay to do with your brother then it would be OK with your sister, too, right?’ Jenna said as she took a step toward Jill. She was unbuttoning her top as she spoke.
‘What would be OK?’ Jillian asked, truly surprised. She watched mesmerized as her little sister opened her top and exposed her pretty pert boobies. ‘I’m so fucking hirny, Jilly. I bet you are, too. Let me get you off. It’ll be OK. You won’t be cheating, right?’ Standing directly in front of Jill now, Jenna took her big sister’s hands and brought them up to her tits. Jill offered no resistance. Jenna moved even closer and whispered in Jill’s ear. I could hear every word of their exchange. My dick was already hard again. Had I died and gone to heaven? ‘Let me eat your pussy’, she breathed into Jill’s ear.
