He was knotting up, which I learned later, is what happens when the base of his penis swells up. Dogs knot up in order to trap their cum in the femal.... This is to ensure his sperm stays in the female. He was knotting up behind me so he could fully breed his bitch. I was his willing bitch.I still could not move. The dog was draped over my back and his dick was buried in my cunt. It felt enormous. I could still feel spurts coming out of him. The girls asked if I was OK. I could not. Then he eased back a bit, rolling his tongue around and around her luscious nipple, forcing more blood to flood the tiny tip.Anita sighed and felt her nipple stand up straight and tall. Leaving it slick with his spit, Chuck took his mouth away from her tit and covered it with his hand instead."You like this, don't you?" he asked, speaking to her flushed face. "A little slut like you really gets off on this kind of stuff! You are a real cunt, Anita, and love you for it!"Hearing his brother talk. She’s really good. Definitely we should check out her multiple exposure photos. I’m sure we could learn a ton more from her.”“I’d like to see that.”“And we’ll have time over break next week to practice more.”“If we can pry you away from Heather,” Muireann joked.“Come on,” I retorted. “It won’t be that bad. And besides, she’s into photography too, so she’ll be tagging along.”“Does she take a class at her school as well?”“I think so, but I never really know what she does, honestly!”Muireann. Now a friend who I met some time ago gave me a whole carrier bag filled with them, she said she had so many and would I like some, so I said yes of course!So over time I began wearing them, but never did anything else with them.Yes of course I wear them everyday as a normal item of clothing but in addition I like using them when I have sex, usually on my own, but I would love to try this with a date and quite soon as it is so kinky, I am sure you will all love what I do!Up till now I have used.
