I had no idea if she is doing it intentionally. So I applied the brake again. She hit me with those melons and never uttered a word.Unfortunately, the... shop came. She did her shopping while returning I had no chance. I was not able to masturbate that night. The next day we left for Mumbai. All the way through our flight I was thinking about her. Was she doing it intentionally?I have a cousin in Mumbai so she went to her place to stay. I went to my house(my old house in Mumbai). That Sunday was. I lead her out of house to our car she sits in front and I seat belt her in and unbutton her raincoat. We drive across town and when we stop I roll down the window so any trucker can see her tits. We finally park in the in the lot and I lead her in. We we look around not very crowded we walk to the clothing section and the girl that is working in the section walks over and asks if she can help. I say sure I then remove my subs coat she is not even startled as she looks at he. She does say you. As my first spurt of cum shot into Allie’s ass Allie cried out. I felt warmth hit my chest, and realized that Allie was cumming too. I stroked her as her cum shot everywhere as my cum was filling her ass. Shelly was cumming from Allie licking her clit so we all were moaning as we came. Finally as our orgasms subsided, Shelly grabbed a few towels to clean up with. “Well that was fun. Not bad for a first round” Shelly exclaimed. “Oh my God” Allie agreed. “That was amazing. His cock was everything. After all, she's your sister, right? She deserves better than a premature ejaculator.So you force it in just alittle deeper, and she screams.Nothing over her mouth this time. Nothing to hold her back. Your little sister Lauren SCREAMS as you shove your cock deeper inside her, and, god help you, you love it.She's begging you to stop now. At least, you think she is. She's saying something, but between her pained gasps and your arousal, you can't hear her.(edited)So you force it deeper still.She.
