The men were watching football while the girls were chatting away. We'd all had quite a few drinks and that was fine as none of us were planning to do...anything useful for the rest of the day. As the afternoon wound up, I could see that my sis-in-law had passed out on the sunbed outside and so my bro called it a day and packed off the guests and it was just the three of us.My bro and I cleaned up as my sis-in-law snoozed away. Just as we're finishing up he got a call, our parents were in town. I slide my panties down my legs and sat on the edge of the desk, spreading my legs to show him my freshly shaved pussy. "Open it, he told me."I reached down and held my pussy lips open to show him my pink, wet hole. He walked up to me and began to slowly rub my clit in a circular motion between two fingers.I reached for his jeans and pulled open the buttons. He pushed his jeans and boxers down, his thick black cock already half hard. He took it into his hand and began to rub it up and down my. “I wouldn’t want you mad again like last time” “Well, you know I’m not exactly proud of what we’ve done” I said. “It really is wrong on so many different levels.” “I suppose” he said, staring into my eyes and lightly caressing my arm with his fingertips. Tim grabbed the edge of the sheet and slowly pulled it down, gradually exposing my breasts. I had a knee-jerk reaction to pull them back, but stopped as I watched his gaze scan over me. It gave me an absolute thrill to watch the way he looked. From that day we try to kiss and have some play with each other. But my best day came in my life in the form of her parents leaving her and going to attend a marriage at her native place leaving her alone in her house asking my mom to take care of her.So they left in the early morning and I got ready to college, while I am having breakfast she said her parents left and she was alone. Then I have asked her shall I come to your home as my mom is busy with her house hold works.So without going to.
