It was the 4th of July and my sister in law and her husband have a big cookout at their house every year. My wife and I always stay over night because we drink and it’s an hour drive home.
It was the end of the cookout. People were leaving. It was just the 4 of us. My wife and her sister wanted to play truth or dare. Me and my brother in law rolled our eyes, but agreed to play. Keep in mind we are all buzzed at this point. Feeling good. Not drunk.
The game started out innocent. All good fun. Then it slowly started to get intimate. One of the rules the women came up with was… you can’t pass on a truth or dare. You had to answer honestly or do the dare. There was no backing out. My wife dared her sister to show her tits. She happily obliged. Her husband was a little Leary about it. But she ultimately did it. Great tits too. Then my wife was dared to show her bare ass. You get the idea. After a couple rounds of us showing our parts, My wife dared her sister to suck my dick. I was in total shock. My wife wasn’t the type to share. We have done a couple FFM threesomes in the past, but nothing like this. Her sister was a little hesitant. She looked at her husband and he said “ you can’t back out. Those were your rules” she said “ you’re right. I did say that.” She told me to sit on the couch. I pulled my dick out. She got on her knees in front of me and without warning engulfed my dick. I let out a moan. She was going tip to base on every thrust. Swallowing my cock. Incredible blowjob. Honestly the best I’ve ever had. Meantime, my wife and brother in law were sitting there watching. I could see my brother in law was uncomfortable. I asked if he wanted us to stop. Game aside. He said “ No, she seems to be enjoying it” I looked over to my wife. She was visibly horny. I can tell by looking at her when she’s horny. Her eyes are glued to What’s happening. The loud slurping/sucking sounds were echoing throughout the room. After about 5 minutes I told my sister in law I was gonna cum. She deep throated my cock and I shot my load directly down her throat. Leaving her no choice but to swallow it all. After I emptied my balls, she pulled off with a loud slurp. My cock was visibly twitching and shiny from her mouth. She wiped her mouth and sat down next to me and said “ Jesus, that was a lot of cum.” My wife asked her sister “ where did you learn to suck dick like that” I’m kinda jealous “ I laughed. After a couple minutes we went to bed. My wife was so turned on she wanted me to fuck her. I did.
Woke up in the morning and not a word about it. We ate breakfast and headed home. It’s been 2 months and it hasn’t been brought up. I’m hoping it can happen again. That was a world class blowjob.
