Michaela, her husband, Dave, Brian and I set about clearing the table and cleaning the kitchen.As we were finishing clearing the table Michaela asked,...“So what was going on under the table between you two?”“Huh?” I said with a look of confusion. “Nothing was going on.”“Oh, come on, Jenn. You were beet red and I thought you were going to come sitting right there in front of everybody.”“Oh my God, Michaela.

With a mighty grunt the man released his semen into my rectum.My noisy reaction attracted other men to my rear hole, now slightly lubricated by the first man's cum. They added to my discomfort, fucking my ass and shooting their load into my rear hole, until this orifice was also oozing gunge. One man returned to my pussy, but when he came he pulled out and sprayed my bottom and the back of my dress with his cum."What did you do that for,.
