Her cunt juices were working as lubricant and my cock began to move in and out freely very soon and my horny, cock hungry sister arched back to get my...cock in her pussy as far in as possible.“Yesss brother, fuck me … fuck me … …I am loving your cock in my dirty cunt … … .my brother’s cock in his sister cunt … …fuck me … ram your cock in my hungry choot … I love you Bhaiya”I started fucking her at a faster pace now, my balls banging on her butt with every thrust in. I was fucking her hard and. ’ ‘Yeah, I’m pretty tired.’ I replied throwing in a yawn to accent the point. ‘Well there goes my hope for another round after dinner. I thought we could get something to eat, maybe share a bottle of wine and then go back to bed.’ Lorna informed me. ‘I think I am too wasted for that. I may have some food delivered and catch up on some sleep.’ I said hopefully shutting down the conversation. Lorna started getting dressed saying, ‘I understand, we aren’t nineteen any more. You impressed me going. She told me of old boyfriends I never knew of and dug up a little dirt on some of our family. Good times. We both had our shades on and I couldn't help but take in her beauty without her knowledge. Her waist was usually below the soothing water but her breasts were exposed to me with nothing more than a sheer layer of pale blue fabric for protection. The cool water would periodically wet the fabric inducing an immediate reaction. I could see that her nipples were quite large. They would tighten. Would she understand? Would she forgive me? I looked up and met her eyes. She held out her hand to me, inviting me to touch her. It was so wrong, affecting her without warning. She had no idea of what I felt.I took her hand, but she didn't react. Her voice remained steady on the phone and she pulled me forward. I was relieved to know that she wasn't going to turn into the mindless sex animal that I already felt like.She watched as I reached out and slid my hands along her thighs outside of her.
