Then it happened. It was Sarah's eighteenth birthday. Sarah and I and Lauren had planned it all out. Sarah had always wanted to go on a cruise. So we booked a luxurious suite on a top of the line ship. We would be gone for ten wonderful days visiting the Bahamas, basking in the sun and relaxing. We had a great time planning and an even better time shopping. As part of her birthday present, Lauren took her out and they bought bikinis and wraps and sexy island wear. Both Lauren and Sarah looked like models out of the swimsuit issue of a magazine. Both tall and tan, both with blonde hair and blue eyes, both with sculptured bodies of firm flesh. As each tried on another outfit, my cock became more and more engorged. Then when Sarah came out in a tiny thong bikini with a small gold embroidery that said sexy, I thought I would loose it. "I thought this was a family vacation" I said. Sarah jumped in "Mom told me to get it; she said if she had my body and was 18 again, she'd wear it!" Lauren appeared "What John, you know she's a hot, let her have some fun on the beach, anyway, we won't be far behind."
"Okay" I said "but I'm not going to spend the whole vacation chasing guys away, you'll wear it at your own risk." Sarah giggled. "Do you really think it will cause a fuss? Where we're going there will be so many women, probably in less then this, no one will even notice." "Oh, you mean like this?" said Lauren, unsnapping her top and letting her breasts fall from out of the cups. "I might just decide to wander the beach topless and if I do, Sarah's going with me." Sarah blushed. Lauren looked at her and said "Come on, you know you have a great body. John, tell Sarah that she'll be as hot as any women there!" Sarah immediately looked at me; her eyes seemed to be searching within me, burning into my soul. She was still flushed and it seemed like her breathing was more rapid. "Sarah, let's compare tits" Lauren said, and she stepped behind Sarah and undid her top. Before Sarah even realized it, her breasts were exposed and her nipples instantly hardened and began to peak. Sarah was still looking at me and I thought that I saw her eyes wander to my crouch to where it was now evident that my cock was straining against my jeans. I was just hoping that the pre-cum that I could feel starting to ooze from my cock, wouldn't soak through my pants.
Sarah instinctively started to cover her breasts, but Lauren gently held her arm and said "It's okay, it's just your dad and I, you don't need to worry about us." Lauren stood next to Sarah and looked at me "See, we will make quite a duo on the beach, I just wish my breasts were still that perky!" Sarah didn't say anything, but she looked at me and smiled. Her nipples were now little pebbles and her stomach was flushed. Lauren grabbed her top and headed for the bathroom "I have to go, I promised to finish writing the procedures manual before I leave."
Now it was just Sarah and I in the room. She was still standing there, looking at me, I was lying on the bed and feeling very uncomfortable. Sarah then, without taking her eyes from mine, slid her hand down across her nipple, stopping only slightly to squeeze it between her fingers. Then her hand traveled downward, over her chest and her tummy stopping at the top of her bikini bottom. Then without a word, her fingers inched into her pants and I could see their outline as they snuck below, covering her pussy and then, bending her knees slightly, she closed her eyes and took in a deep breath of air as her fingers curled into her slit. Then, just as suddenly, as if she woke from a dream, she grabbed her top and spun around closing her bedroom door behind her.
I was in the state of shock. What should I do, should I talk to her, should I say I'm sorry? But sorry for what, what had I done, I hadn't asked her to touch herself. I looked down, I had soaked through and the growing wet spot only accentuated my enraged cock. I was afraid to touch it for fear that I would immediately cum in my pants. What was happening, this wasn't high school, this wasn't some whore, this was my daughter. Lauren appeared and gave me a quick peck on the cheek and said she'd see me in three or four hours. I got up and headed to the shower, a cold shower would help me sort things out.
I stripped down, my cock fading at last but I was still woozy from what had just happened. "Get a grip man!" I said to myself, I'll take a shower then talk to Sarah, she's probably really embarrassed. The room was filing with steam; I pulled back the curtain and stepped in. The hot water felt good and I draped my head so that the stream ran over it and down my back. I was trying to figure out what to say when suddenly I felt a soft hand on my shoulder. I snapped up and spun around. There was Sarah, she was beautiful, and her skin seemed to glow as flecks of water fell on it and formed little rivulets down her body. She looked into my eyes again, this time though it was a questioning look like when she use to ask me if she could buy some candy or if she could go to the mall. A thousands thoughts raced through my mind, everything told me to turn away, maybe kiss her gently on the forehead and tell her she has to go, but...
She took just the tiniest of steps forward but it might as well been a leap into my arms. I reached out and pulled her to me, her eyes closed and I lips met. The warm water was dancing off of my back but the warmth of Sarah's flesh against my own engulfed my whole body in a fire of passion and lust. Our lips parted and I felt the incredible warmth of Sarah's tongue. My hand slide down her back and I held her ass in a firm grip. Sarah made a small gruntle sound as I massaged her cheeks. Her own hands moved until she too grabbed me pulling me closer to her. She tasted like spring and sassafras and early morning sunshine.
My cock started to fill and began to rise, resting gently between Sarah's legs. She moved a bit and I felt my cock brushing against her pussy, the pussy I had dreamed about, any thoughts of turning back were long forgotten now. There was incredible warmth radiating from her slit and as we kissed, she gently moved back and forth across my cock. I could feel the slickness of her pussy and my own pre-cum dripping and coating us. My hand went to her breast and she bit down slightly on my lip and I held it in my hand and opened my fingers capturing the harden nub on top. Her breathing was deep and shallow and her hips were now moving in little swirls. She held onto my neck and suddenly wrapped her legs around me. My cock slid up against my stomach, caught there by Sarah's pussy. She continued to dig her heels into my back and I held her as she rubbed her wet slit up and down my cock, her breathing coming faster and faster and her urgency more deliberate. I wanted to scoot down, to let my cock slip into her, but her grip was too strong. Suddenly, she bit into my shoulder and then thrust so quickly that before I knew it my own screams were mixed with hers. My cock pumped out huge gobs of cream as she withered against me, enveloped in her own climax. Her legs loosened and she slid down my body, ending up on her knees. She looked up and gently kissed my cock, allowing her tongue to dart out and catch the last little droplet of my cum. Our eyes met again and she smiled, then she said "It's okay dad." That was it. It's okay dad.
She then stood up and kissed me again full on the lips, pressing against me. She stepped out of the shower and grabbed a towel, wrapping herself up; she closed the curtain and said "This is the best birthday present ever. I can't wait until the cruise!" And she was gone.
