One night after doing some coke which always made my wife very horny, we were lying in bed when she asked me if I wanted to watch her have sex with our dog. Naturally I said yes. She got on all fours , he wasted no time mounting her. He fucked her hard and fast but just as he was about to cum, she pulled him out of her. One nite while partying some more, she said she wanted to do it again, and again she pulled him out when he was ready to cum. This became a weekly thing, but she’d never let him cum in her. One night when her son was staying with us, his girlfriend spent the night.
They were sleeping outside in a tent one night and we were lying in bed, when my wife told me if grabbed a pair of her sons girlfriends panties she would wear them and have sex with the dog and that she would let him cum in her. I slipped out & grabbed a pair of her panties, brought them back & gave them to my wife who put them in and got on all fours, letting the dog mount her. She pulled the panties to the side and guided his cock into her pussy.
He started fucking her hard and fast, when I heard her moan, as the dog pushed his knot into her pussy and held still. She was finally letting him cum inside her. They stayed joined together for about twenty minutes. When his knot reduced in size and slipped out of her, she pulled the panties over her pussy letting the dogs cum drain into them. When it was finished dripping out of her pussy, she took the panties off, and put them back in her sons girlfriends over night bag. The next day, this girl took a shower and put the panties on. Later that day I asked my wife what she thought about what she had done. She only smiled at me, took my hand inside her own panties and she was soaked. She told me she had been thinking about it all day.
Needless to say, whenever her future daughter in law would spend the night & her son & her would sleep in a tent, she, herself would grab the girls panties and let the dog fuck her while she wore them and let him cum in her pussy, letting the cum drain into the panties before returning them.
