I nodded my head and licked my lips sexily. She smiled sweetly.Without warning Cindy drove her hips forward and buried all 8-inches in my cunt. The sh...rp slap of her thighs against my ass cheeks echoed across the room. The shock drove the air from my lungs. But just as quickly, I felt the divinely erotic sensation that only comes from having a massive penis- whether it's flesh or silicone- filling up my pussy.I moaned with pleasure and egged her on, "Oh fuck yeah Cindy, that's it. Your cock. Most probably I am fulfilling the desires of both after this part of the story.After that class incident we started playing with each other like squeezing boobs, fingering her pussy at many places like we find that there is least probability of people coming there,but still not finding a place for proper fuck. We have joined a common gym and asked coordinator for morning timing so that we can utilize the empty corridor to do all of our sexy fun before entering into gym.Once while i was. I always begged you to take me in." She sniffled. "I accept your invitation and will be there as soon as I can. You just made my whole day and week." I'm glad you feel that way and long to feel you next to me." Night, darling." Night Cynthia."I took a deep breath and exhaled slowly. I don't know why that was so hard.

From sitting at the distance only I could make out moving shades of sister. Suddenly an idea stuck to my mind that if I peep through the door I can see the beauty of bare sister. But I felt hesitant at beginning fearing that she will come to know about what I am doing. However I thought I should not miss the golden opportunity slowly I kept aside the plate and without making any noise I went near the door. I held my breath and I peeped from distance. I could see the part of hips but could not.
