It was huge. Big and round. From the porn I looked at online, it looked more like a Spanish or black girl's butt. It was the perfect example of a big ...ubble butt. The fact that Lisa was thin with a small waist made her butt look that much bigger.I stared at her butt for longer than I should have, my penis growing in my pants. When it looked like she was going to turn around, I quickly walked away and went into my room and shut the door.I took off my pants and started playing with myself. She screamed even louder this time as her sphincter fought with the second cock, Wave after wave of pain shot through Tina's bowels and she felt like she was going to sh*t herself at any moment. Eventually the agony subsided and was replaced by the great sensation of anal pleasure. Meanwhile the two guys with Nat had shot their loads. One had cum in her mouth and the other up her asshole. Natalie moved over to Tina and started fistfucking Tina's cunt with the two cocks still in her asshole.. A group of girls marked her 18th with a big party at the Italian place that served everything family style. She marked it by showing up at my house in cheer shorts and her PE shirt that she had cut into a crop top. Do you know what cheer shorts are? I told her no and she sat outside my apartment for an hour until I let her in. She wanted a drink. That was a first. I poured her a Jack and diet coke and she drank it like an alcoholic housewife in two swallows. I poured a second and she nursed it.. At 6pm the couples were called for dinner and after they had finished they were taken back to the barn. The women stripped and laid on the benches. The sheets were lowered again so that only from the waist down was visible. Once everything was in place three new guys entered the barn. They were told the same thing as the three in the morning: Women who orgasm are more likely to get pregnant. The guys were told to chose a woman and they were then to fuck the woman and empty their cum into them..
