I turned her around and got on top, and fucked her in missionary for few minutes. She was moaning like a sex goddess, everyone could hear us so it was...more thrilling. My abs were hitting the top of her pussy and the wetness made the sounds much louder and the scent of sex was everywhere in the air. Then we changed to doggy, but she was lying down with her legs closed so this makes her pussy so tight and enjoyable for both of us. I licked her ass and pussy from behind as I love that angle and it. As we disengaged she remarked, “This is my first kiss in over one year. I think Penny would not mind to share you as my date for the day. After all we are sisters.” I smiled at her but did not say anything but Penny jumped up from my lap pulled me up with her and put my hands around her sister. I needed no further signal and hugged her sister and kissed her everywhere on her face repeatedly. It is obvious that these kisses had rekindled the sexual desire in her. She responded by tongue kissing. I left my plate and went towards parking. She was already there in a dark corner. I called her inside my car and we both started on a drive. Now this function was on a highway party plot so I took the car on highway. She suddenly started removing her top. I asked her “Bahot Jaldi hai” She said “Isme fir time kyun waste kare.”She was in her bra and removed her pant also. So imagine friends a hot girl sitting besides you in two piece all set for sex and you are driving. After doing that moved her. I decided to ask if he was going to take me home. He just said "don't worry boy". He made me masturbate for him. This time I had my legs up facing him. He fingered my ass as I rubbed myself. He sniffed his fingers and then would plunge them into my ass again. My cum shot up over my head and his the side window. He had me put one leg behind his head and one over his lap. He groped my balls, cock and ass as he drove. I was tired and the constant bouncing was relaxing. I must of fell asleep.
