And here he'd already given her several and she wastalking like he was going to keep fucking her even after he'd already cumonce.Then the thought stru...k me, he was going to fuck her in the ass. Iscrambled out of bed and found myself watching through the cracked dooras he pulled out of her pussy and pushed his huge cock against herasshole just as he began cumming. She was pushing back onto him. Therubbery head pressed tight to her rosebud as his cock spewed its jizz.Some escaping to dribble down. I had to lay there and recover, getting strength back in my body. Jim said, “Everyone has left, I am going to remove the blindfold now.” It took a few minutes before my eyes had adjusted to the room. I had been unstrapped and was allowed to sit up, but my ass so beat up did not like that position. Jim let me know that everyone approved of my performance. I could now see him and an empty room with only a table with some items near what looked like a bathroom. Jim then told me that there was. I knew it was incest to want my older sister but what boy does not want to fuck his older pretty sister. Older sisters are made for sex to my way of thinking. After all those years of being cock teased; my simply taking her mouth to mine had marked her and she knew it. I have read that 18% of College girls had fucked a brother and sibling incest is the most common.Later I went to Karen's room and I respectfully knocked on her door, K called out "come in" and I entered. K was working on her. ”Susie stuck her tongue out at me and said. “You know ... that rubber dick has been in your mom’s cunt.”I replied. “No wonder it tasted so funny.” And everyone laughed.When everyone was marked, the girls got up and re-applied their lipstick and rotated to the left. As I knelt in front of Martin I saw that Susie got almost to the base of Martins dick, however Skeeter’s cock was the longest and fattest of all the cocks here, but even Skeeter’s wasn’t that much bigger than the rest.I swallowed.
