Ohhh yaaayy ….. ooohhh Myy Goodd”Huma :”Yyeess Boss ….. like thatt ….. yyaaahh …. oh yes, oh yes, oh yesss, yes, yes, yesssss ….. aaahhh...”I was breathing heaviliy. She kept going like a hungry bitch. She was breathing heavily as well. After fucking like this for 5 mins, she wanted to change position.She wanted to do doggy. Since, i was tied up, she got a chair and bent down, holding the chair for support. Slowly she help me insert the cock in the confines of her pussy. I started to pump her. I followed them slowly behind. I ringed my sisters mobile. She replied that she is out to her friend’s home and will be back to college by Sunday evening. Now time was more than 7.30 pm in the evening and they were fully wet after their water games in the sea. Now my sis and that guy was alone along with their friends and they were looking around for people after confirming there is no sign of peoples on the area the two guys removed their pants and shirt. My sis was shocked on seeing this and. As I suck gently on her clit, letting my tongue occasionally wash over it, I grab her knee with one of my hands pulling her leg over my right shoulder to open her up wider letting her weight rest on my broad shoulders. As with her nipples, I suck deeply before pulling away hearing her slight moan as she feels the intense pressure on her clit. Releasing I capture the sight before my eyes, her pussy now wide open, clearly wet and wanting more. With no hesitation I suck on two of my fingers before. . She woke up suddenly and I got terrified.. Uffff..!!! She didnt ask anything.. We had lunch and started to talk about my parents.. After few mins,Preethi: Y you had put your hands on my stomach??Me: Sorry..Preethi: Tell me why??
