I'd crashed out one evening in my girlfriend's room. We'd been watching some damn video and it was more than I could take. I fell asleep right in the middle of it that night.
I woke up briefly later. The TV was off and the thing that woke me up was an incredible norm wrapped around my cock. I was still half asleep as I felt those lips sliding up and down my shaft that evening.
That mouth was amazing and it didn't take me long to give up my cum. Even almost asleep I shot a huge load into right then and there.
I dozed off again, waking up a short time later. I had no idea what time it was, but I knew it was time for me to go. I looked around for Teresa, finally finding her curled up under her blankets asleep.
I whispered goodnight and headed outside slowly making my way to my truck. It was a beautiful night that night and as I stopped to light a cigarette I heard a voice.
"Hello Eric."
I about jumped out of my skin at that. Turning around I saw Teresa's older sister Bonnie sitting there. She was sitting in a lawn chair drinking a beer and smoking a cigarette.
As sisters, the two of them couldn't be any different. Teresa was shorter which made her DD tits stand out more. Bonnie was taller with the same chest, but it looked smaller on her. Teresa was brunette and Bonnie was a redhead. Teresa had the girl next door thing going on while Bonnie gave off the vibe that told you she loved to fuck and she didn't care if you knew it or not.
"Hey Bonnie. You scared the life out of me."
She took another drink and smiled. "Sorry about that. I just wanted to ask you something."
"What's that?"
"How was the blowjob?"
I was reaching for my keys when she said that. I stopped when it registered though. "What did you say?"
"I asked you how the blowjob was."
"How the hell did you know about that Bonnie?"
"Simple. I was the one that sucked you off. So how was it?"
I looked at her in the dim light not believing a word of it. She had a sly little smile on her face though that made me uncomfortable. "You gave me that blowjob? I don't believe it. Tell me how you did it."
"Simple. I came into Teresa's room to turn down the TV a little. You were on the couch covered up and Teresa was in bed. Both of you were dead to the world so I got curious."
That was the way it was when I woke up, and a twinge of guilt hit me. She kept going though.
"So I snuck over the couch and pulled your blanket down very gently. I was in luck. You hadn't pulled your jeans back up yet. So I could see everything."
"So then what?"
"I pulled off my shirt and very gently sat down to play with your cock. And before you ask I had two reasons for doing that."
"Ok. I'm listening."
"First of all Teresa told me exactly how big you are and I wanted to see that for myself." Bonnie smiled brightly then and pointed to a spot on her throat. "She wasn't kidding. You were about that deep when you shot your load. It went straight down my throat."
I was getting hard again just thinking about it. "So what was reason number two?"
"I knew you'd fucked my sister tonight, and I've really wanted to taste her pussy. Since it was all over your shaft, I sucked you clean. You're welcome by the way."
I didn't have words at that point. My mind short circuited at that. I couldn't picture Bonnie wanting pussy, much less her sisters. She drained her drink as I tried to find something to say. The only thing that came to mind was, "So how was it?"
"She tasted fantastic."
"So you're telling me you're bi then?"
"Very much so. And kinky too. That's obvious though isn't it? I don't know many other girls that fantasize about being tongue deep their sisters pussy. Do you?"
I shook my head. I really didn't at that point, but the mental image was a stimulating one. I could picture Teresa naked with her legs spread wide and Bonnie just as naked with her head buried between her thighs. I loved the thought though and told her so. Then I asked, "So why don't you go for it?"
"You don't think I've tried? My sister doesn't get subtlety though. I've hinted at it several times, but it just doesn't register." She fell silent for a moment as I stood there hard as a rock in front of her. Finally she looked up and said, "You never did answer me you know. How was the blowjob?"
I admitted it then. "It was fantastic. Teresa isn't usually that good unless she's really turned on. That's the only time I get to use her throat."
Bonnie nodded knowingly. "That's the difference between us. I love a hard cock stuffed right down my throat every time. Some nights are really interesting too. That's when I love getting my face fucked."
"How's that work?" I had a mental image of it of course, but I'd never tried it.
Bonnie smiled. "Let be give you an example." She sat up straight in her chair and motioned to me. "Stand right here please."
She was indicating a spot just inches away from her. I didn't see the harm, so I stood there looking down at her. She looked up at me then. "So usually the guys standing right where you are. Then he reaches down and wraps his fingers in my hair. I like it nice and tight simply because he's going to control my head and get what he wants that way."
My hand reached down and slowly wrapped itself in the hair on the back of her head. "Like this?"
"Exactly like that only tighter. Remember you're going to be in complete control." My fingers tightened until she gasped with pleasure. "That's perfect Eric. Just like that."
I pulled her head back slightly, exposing the neckline of her shirt. I wanted those tits right then, so I thrust my hands right down her top filling it with one massive mound. The nipple under my fingers was nice and hard and keeping in character I pinched it making her gasp again.
"Oh yeah. Do it Eric, make me scream."
"Waking everyone up probably isn't a good idea you know."
Bonnie smiled. "Then shut me up Eric."
I reached down with my free hand and unzipped, hauling my cock out. I ran it across her full lips, then thrust my hips forward sliding deep into her mouth.
Bonnie's eyes closed as her lips slid all the way down to the base of my shaft. I knew right then she was telling the truth. She'd given me that hot blowjob while her sister slept nearby. My cock was plunging into her throat again as I looked down and asked, "So you want your sister's pussy do you? You want your tongue deep in Teresa?"
She nodded, her lips stretched around my length. "Ummm hunmm."
"And you want me to help you with that?"
