Sisters

I left Teresa asleep. We had our usual marathon sex session that evening and she was exhausted. So I slipped out the back after taking one last look at her naked body.

I was headed to my truck when I heard a voice. “Hey Mike.” I about jumped out of my skin before I realized who it was. It was Bonnie, her older sister.

Bonnie was back from college and obviously a night person. She was sitting outside with a beer and a cigarette enjoying the night air, or so I thought right then. As I looked at her I realized she was showing a lot of skin tight then and I can’t say I didn’t approve.

She was a tall redhead and that night her D cup tits were pretty much out in the open covered only by a bikini top. I appreciated the cleavage she was showing off as I looked down at her. The rest of her was wrapped in tight shorts that not only showed off her figure, but it displayed her long legs perfectly.

“What’s going on Bonnie? You’re up late.”

I saw her grin. “I was watching the show.” She looked me in the eye as she added, “You really had Teresa thrashing all over the bed.”

That stunned me. My jaw dropped as I stared at her in disbelief. “You were watching us?” Bonnie nodded smiling.

“I really liked it when you got on top of her and fucked her tits. That was hot.” She took a drink and then said, “And of course when you fucked her doggy style.” Bonnie was smiling and looking up at me like it was nothing

I finally had to ask. “Why the hell were you watching us?”

“Come on Mike. It’s a live sex show. Who can pass that up? I do have another reason though.” She took a drag from her cigarette before telling me about that.

“I’ve got a thing for my sister Mike. I discovered girls in college thanks to my roommate and a bottle of wine one night.” I saw her smile at the memory. “When I got home I got that vibe from Teresa.” She looked up at me and in a serious voice said, “She’s really curious Mike. If not bi herself.”

I shook my head at that. “I think you’re wrong Bonnie. I’ve mentioned that before and she’s not even close to considering it.”

Bonnie shook her head. “You’re wrong Mike. But it’s one of those things only a girl will see. Besides, I know differently from experience.”

I looked dubious and Bonnie grinned again. “Remember last week when you took her to that party and she came home blasted?” I did. I’d had problems on that drive. Teresa didn’t want to keep her clothes on until we got home and started stripping down as we drove through town. As enticing as that was she pretty much passed out before any fun could happen. I managed to get her awake enough to take her in and put her in bed, but that’s all that happened that evening.

Bonnie waited until I nodded, then dropped her bomb. “I came into her room and found her naked on top of the covers. I couldn’t resist Mike. I stripped down and licked my way up her thigh before going down on my sister.”

She watched for my reaction and it was twofold. I was shocked of course, but the part of me that wanted to see Teresa doing that was excited. I got hard right away and Bonnie’s eyes were at the perfect level to see that.

“You should have seen it Mike. My little sister was hot that night. Her hips were pressed against my mouth and she came again and again.” Bonnie smiled at the memory.

“So why are you telling me this Bonnie?”

“Because, when I was watching you two tonight I had an idea. And I figured I’d run it past you to see what you think.”

I had no clue at that point what that could be. “Ok. I’m listening.”

“I’m addicted to that pussy Mike. I really am. I could do her every night and not complain.”

I was picturing that mentally right then and the picture didn’t help my aroused state any. Then she went on.

“I want to help you realize your fantasy. I want you two to have a threesome with another girl. And that girl will be me.”

I smiled then, staring at the deep cleavage her bikini top was revealing. “I don’t think I’d complain if that happened.”

“I didn’t think you would. How many guys get two willing sisters together like that? Not too damn many.”

I agreed. Bonnie made things interesting then. “There’s another thing too.”

I raised an eyebrow. “And that would be?”

“You’ve got the taste of my sister’s pussy all over your cock right now.” I nodded. “So until we get her where we both want her I’ve got a proposition for you.”

Bonnie looked up and very calmly said, “After you’re finished with her on nights like this, make sure you don’t leave before I can clean you up.”

My jaw dropped again. “You mean….”

“I mean I’ll suck that big hard cock of yours until I get every drop of her off you. And of course I’ll want your cum too. So what do you say Mike?” She reached up and ran a hand softly over the bulge in my shorts.

I caved immediately. “It’s a deal. How do you want to do this?”

She smiled and stood up, snuffing out her cigarette. “Let’s go for a short ride Mike. I’ll show you.”

It wasn’t even a mile to my favorite parking place. It seemed longer though because my eyes were focused on Bonnie’s tits most of the way. They bounced wonderfully with every bump in the road we hit. She caught me watching and just smiled to herself. Once the car was parked though things changed.

Bonnie immediate slipped out of her bikini top then. I looked down at those tits with their bright red nipples and groaned. “Damn girl, you should let those out to play all the time!”

“At college I do.” She reached up squeezing them before gently running her fingers in circles around those hard buds. She watched my hand fall to my lap, stroking my cock through my jeans. “I’ve got this shirt that drives people wild when I wear it. It’s silk, and it teases my nipples getting them good and hard. Of course I leave my bra at home when I’m wearing that.”

She reached across then and replaced my hand with hers, stroking my hard cock through my jeans. I’d never had sisters before and while Teresa was amazing, I wanted to find out how her sister handled things.

I saw her smile again at the look on my face. “Want to hear the details of my evening with my sister?”

“Hell yes! Tell me everything.”

“Teresa was pretty much passed out that night. So I walked in just looking at her laying there. I could see how far out of it she was and that was perfect for me.” Bonnie gave me a grin. “I’m like you. I’m a boob girl. That’s what attracted you to my sister isn’t it?”

I laughed. “Honestly, yeah it was. I dropped by one day and she was out playing with your younger sister. I’d never seen her braless until that day. You could say they caught my eye.”

Bonnie started working on my belt and zipper. “I know what you mean. I couldn’t pass them up that night either. I loved how they felt running my tongue over them before sucking them into my mouth.”

I could picture that. “Anyway, I had other things to do that night. So I just kissed my way down her body then and her legs spread slowly as I got lower and lower.” Bonnie had my jeans undone by then and pulled out my rock hard cock. “You should have seen me crawling up on the bed, my face right there just inches away from her pussy.” Bonnie was looking up at me, her hand wrapped around my cock. “So I leaned forward and tasted my sister.”

I groaned again at the mental picture. “How did she taste?”

“Absolutely fantastic. All it took was one little lick and I was hooked. After that I had my face buried in that soaking wet pussy.” Bonnie took a deep breath. “You should have seen her Mike. Her hips were rolling slowly and she was moaning softly not even knowing her own sister was eating her pussy. She even came for me, right before she passed out for good.”

She looked down at my cock then. As I watched her she ran her tongue over the head, getting a good taste of her sister and me together. I saw her smile and then move a bit, kneeling over my lap before she sucked me into that hot wet mouth of hers.

I could just see her lips stretched around my shaft, sliding lower and lower that night. My free hand immediately went to her hanging tits, playing with her hard nipples as she sucked her sister’s taste off me. Bonnie took me deep, then started slowly and sensuously bobbing up and down on my cock.

I ran my hand across her exposed skin and then down to her tight little ass. As she sucked me down her throat my fingers found her pussy, feeling the heat through her shorts. Bonnie’s as moved as my fingers explored her body, pressing back against my hand.

I sat back and she gave me her best, those red lips sliding up and down my length slowly at first, and then finally faster as she sensed me getting closer. I couldn’t hold back. The excitement of my girlfriends sister sucking my cock was too much right then and as she came up I shot my cum into her waiting mouth.

She took a couple of shots across her tongue before sliding me deep into her throat again. She had her lips wrapped around the base of my cock then, taking my cum that night.

She eventually let my cock slide out of her mouth. As she sat up she licked her lips smiling. “That was an interesting mix.” I looked over that hot body and a thought came to me.

“I think we should talk about this more Bonnie.” I saw her sly smile at that point.

“Ok, I’m good with that. How about tomorrow? Teresa has to go to work doesn’t she?”

I nodded. “Then why don’t you come over tomorrow morning? I guess we can talk then.”

I ran her home then, checking to make sure the house was dark before I dropped her off. I drove home smiling and plotting that evening. I was going to get the two of them in bed together. I just didn’t know how yet.

I was up early the next morning heading for my car. I knew Teresa was on her way to work. It was time to plan with Bonnie, and hopefully more than that.

I got to the house and knocked but no one answered. That struck me as of. Just as I was about to leave though I decided to open the door and check on things.

When I did I heard the sound of water running. Looking down the small hallway I noticed the bathroom door was open. So I called Bonnie’s name several times. She finally heard me and surprised me. “Come on in Mike. I was just getting out.”
