She gasped as I roughly nipped her nipples betwixt finger and thumb. The rain continued to hammer down. I realised that no one was about, nor could we...be seen from the road or path. So I became bolder, undoing her belt and the top button on her jeans, to slide down her zip and slip my fingers down to caress a pronounced mound over the top of her knickers.“Don’t!” she moaned. “Stop!” which I took as ‘don’t stop’, such was my carnal lust at that moment as I realised that I was determined to have. Her soft lips cupped the side of my shaft as she slid them down the length of my hard shaft. Her hand was softly cupping my balls as she slid her sweet lips upward to once again circle my pulsating cock head. Pre-cum was oozing from my cock as I watched my sexy sister slowly part those sexy red lips and flick her tongue out to taste it. A string of pre-cum stuck to her tongue as she pulled it into her mouth and savored the salty taste. I observed her beautiful face closely as she moved. Slowly I moved towards her put my tongue on her pussy. She flickered a little bit. I started to go deep inside her. She pushed her pussy lips towards my mouth. After 10 mins she had her first orgasm and started to cum. I drank all her juices. I told her that’s it’s her turn to give me pleasure. She asked me to sit at corner of bed. She lowered herself and started to stroke my penis with her mouth. I was in my 7th heaven. I started to talk to her in filthy language.This continued for another 10.
