I looked up immediately, not believing my ears. My jaw dropped as I saw I was right.
My sister Kim was walking toward me, a huge smile on her face. She was holding hands with an older taller blonde woman.
"Hey big brother." She'd changed her hairstyle, but that and the woman she was with was about the only difference. I hugged her and on the way to her her baggage she introduced me.
"Mike. This is Yvonne. She and I are a couple."
I congratulated them right away, surprising Yvonne a bit. We talked heading toward the car and my sister jumped in the front seat with me. Yvonne took the back and was quiet until we got out of town.
I felt someone tap my shoulder and looked into the mirror.
"Are you really happy for us Mike?"
I nodded. "For one basic reason. If some guy broke my sister's heart, I'd have to beat him senseless. Now I can't."
She looked shocked, but then saw my smile. She laughed and I told her I was happy as long as Kim was. I got a description of their place then. It was on the beach and off the grid completely. Kim told me about it and when she added, "Most of the time we don't even wear clothes.", I couldn't help glancing up in the mirror again. Yvonne was smiling from ear to ear. Her dark hair framed her face and she was nice and busty just like Kim. I couldn't help thinking about that and it didn't help my driving any. I was picturing a lonely shore and a house surrounded by trees next to the ocean. And of course both women walking around naked. At least to begin with. Imagining both of them in a hot 69 somewhere on the beach got me hard right then and there. I tried to get rid of the image, but that wasn't happening. After a few miles passed silently, Yvonne had a question that almost made me drive off the road.
She unbuckled and leaned up against the back of the seat. "Tell me something Mike." I looked up, catching her eye in the mirror again. "Did you really have sex with your sister?"
I was shocked and turned to Kim immediately. She smiled slightly and nodded. "I told her all about it Mike. Go ahead and tell her the truth."
I nodded at her and then at Yvonne. Turning back to Kim I asked, "Did you tell her how it all got started?"
Kim smiled again, nodding. "I did. She knows how you caught me." I looked back at Yvonne then, not really sure what to say. Her dark eyes met mine in the mirror and she smiled slightly.
"I'm not accusing you Mike. Let's just say I'm fascinated by the fact." She paused for a moment. "So how did it work between you two? Did you treat her like a girlfriend or did you two just get together and fuck?"
"Most of the time it was the second. Although we did play boyfriend/girlfriend a few times. But not often."
I saw her nod slightly. I glanced back at Kim just as Yvonne said, "Now that I'd like to see. A brother and sister making out."
Kim turned her head and looked at her girlfriend. I saw her glance around then, realizing where we were. We were just a few miles from home then.
"Turn right here Mike." My eyebrows shot up as I looked back at my sister. "You've got to be kidding!"
She shook her head. "Let's give her what she wants." She looked back at Yvonne then. "Are you sure you really want to see this?" By that time I was turning on the old dirt road that Kim and I had used in the past. Yvonne's mouth moved into a small smile as she said, "I'm sure."
Kim looked back at me as I pulled up to our old spot. I shut off the car and turned back to her. I could see her nipples perking up in the moonlight and remembered just how much fun I'd had with them over the years. Both of us unbuckled then, turning toward each other. Kim scooted closer and leaned in, pressing her lips to mine. She gave me a couple of soft kisses, getting reacquainted with me before her mouth opened.
When our tongues met my hand reacted automatically. It slid up from my sister's waist to cup one of her D cup tits. Kim pressed her body against my hand as the familiar weight filled it. I felt her nipple get even harder then. I heard Yvonne's voice then softly say, "Very nice."
Kim reached for the bulge in my jeans then. I was unbuttoning her shirt slowly as she ran that familiar hand across my hard cock for the first time in ages. At that point I had no idea how far Yvonne wanted us to go, but she wasn't stopping anything. I opened my eyes briefly and saw her watching intently from the back seat, her hands up under her own shirt.
Kim undid my belt and slowly unzipped me then. Yvonne peeked over the edge of the seat as my sister reached in and wrapped her hand around my hard shaft. I felt her soft hand squeeze me gently before slowly sliding my cock out of my jeans.
I pulled her shirt open wide, revealing those big tits. I saw Yvonne grin at that. As I reached up to cup one, her hand slid over the back seat taking the other in hand. She alternated between caressing my sister's tits and glancing over at my hard cock sliding through Kim's soft hand.
"Show me what you did that first night." Kim and I looked at each other then.
"I'm not sure that's possible in the car like this." Yvonne thought for a moment before she said, "Why don't you get out and come around to her side of the car?"
Kim helped me slide my jeans off and I did. I climbed out into the night air, walking around to her side. Kim opened her door and turned my way, taking my cock in hand and stroking it gently. Yvonne was watching intently as my sister slid my cock into her hot wet mouth then. Both of us were staring at my sister's lips as they slid down my shaft slowly, taking me in inch by inch. I heard Yvonne then.
"He's bigger than your strap on isn't he?" Kim came back up and nodded before saying, "Watch this Yvonne."
She parted her lips again and that time she went all the way down, not stopping until her full lips were wrapped around the very base of my shaft. Then she kept deep throating me, sliding my cock into her throat each time. Yvonne had undone her jeans by then and had one hand down the front of them as she watched Kim suck. She saw me staring at her fingers moving under the fabric and lifted her shirt to show me her braless tits. They were incredible, and the combination of my sisters hot mouth and the view brought me to orgasm quickly.
I gave Kim a big mouthful that evening, shooting it all over her tongue as usual. She caught it and eventually slipped off my shaft, turning to her girlfriend. I saw Yvonne's eyes widen as Kim opened wide, showing her all that cum before swallowing it down.
I caught my breath and grinned at Yvonne. "That wasn't all she did that first night." I headed for my trunk and pulled out the old blanket there. I spread it out and helped Kim out of the car. Turned to Yvonne I asked, "Care to get a closer look?"
She hesitated and then nodded. She was standing on the blanket watching as I slid my sister's clothes off. I could see her looking over both of our bodies before Kim knelt, getting into my favorite position. She was on her hands and knees then, that hot shaved pussy and ass facing me. That's when she turned to Yvonne and said, "Get naked baby. I want to see you."
Yvonne did, looking clearly uncomfortable with a man seeing her naked. She stood there though watching as I ran my cock up and down my sister's pussy before sliding it in.
I could see she was fascinated as I plunged into Kim, sliding back out, my cock shining with her juices. Kim was moaning before she looked up at her girlfriend. I saw her pat the blanket in front of her and Yvonne knew what she wanted. She moved, laying down in front of my sister who wasted no time in diving into her hot pussy.
Yvonne and I came at almost the same times that night. My eyes couldn't figure out where to watch. They went from Yvonne's hot body to my sister's head moving as she tounged her friend. Yvonne came that way, her hands squeezing her tits as she did. That was when I blasted Kim's pussy full of brotherly cum, coating that familiar pussy for the first time in ages.
I slipped out of Kim then, my cock still hard and shiny. Yvonne was fascinated by that sight. Kim saw her staring and giggled. "Go ahead. Touch it. I don't think Mike is going to complain."
I saw Yvonne shake her head slightly, but her body said otherwise. Kim knew that and urged her on. "Come on baby. You know you're curious. You've told me that before." I saw her grin as she said, "Besides, my tasty pussy is all over it."
Yvonne stood up and moved closer to me. She looked up at me and asked, "Do you mind?"
"Not at all. Satisfy that curiosity." Her hand shook slightly as she touched my sticky cock gently before wrapping her fingers around it. I watched her hand slide up and down my length a few times before reaching out myself, my hand stopping inches from her full tits.
