At that moment Beth ceased to be my sister, she was a gorgeous seductive young woman and I was a sex starved young man, nature was about to take over.... pulled my boxers off and we tumbled onto my bed. I kissed her as my hand explored her tits that were large and her nipples hardened to my touch. Our breathing came in gasps as we kissed like two long lost lovers instead of brother and sister sharing an erotic moment for the first time. My hands went to her hairy pussy and I had no trouble. He holds up a bottle of sun tan lotion to show me, then steps over and unties the strings of my white bikini top. Pouring some lotion into his hands he begins to smooth it into my shoulders and down my back, stroking every inch with those big capable hands. I’m enjoying the sensation very much as he works the lotion right down to my behind. “I don’t think you’ll need these” he says in his most sexy rumble as he very deliberately unties the side strings of my bottoms. The fabric falls away and I. With a soft, towel I gently blot her sex still wet from her prolonged orgasms. I don’t know how often she masturbates but from the moans she let out, I know she won’t be touching herself, for a few days. I pull off her gag, and give her some water, I hold he head up a little as I tilt the water to her mouth, she drinks greedily, I say softly, “Not to fast Honey”, then give her a little more. With the same towel I wipe some of the drool from her face and hair. I also explained her legs aren’t. She liked it!I grabbed the hem of her t shirt and she moved her arms up for me. I spanked her ass firmly, she squirmed. I lifted the t shirt up with her hands behind her back and wound it round her arms as a restraint. Holding that firmly with my left hand I unbuttoned her designer Jeanmaker jeans and pulled them down to mid thigh. Surprise the submissive slut was going commando and a small wet spot was evident on the crotch of her jeans. Pushing two fingers into slit penetrating her neatly.
