My wife is bi and occasionally over the years has told me how one day she’d like to try bringing a girl in. But we never really talked seriously about it. a week before it happened another semi casual jokingly convo and we both discussed how the first time I wouldn’t do PIV, just try things out first and see where it got us in the future. I obliged she wouldn’t have to worry. The night it happened my wife goes out with a friend for some drinks. They come back and guess around 2 am I wake up to my wife and her friend naked in my bed. They’re kissing, and kind of leading me on. Her friend keeps saying, “oh I bet he likes that. I bet he wants to fuck”. I decide fuck it.. and as I watch them kiss I slip my shorts off still in bed. I’m rubbing myself a little watching them mess around and then I get down at the edge of the bed. I pull my wife down onto her back and begin to eat her out. I reach my hand up over her and over her friend beside her a finger her a little. My cock is throbbing and I decide to start fucking my wife. We fuck around a few different positions, her on her back, she’d flip and I’d fuck her doggy while I watched her eat her friends slit. At one point I stopped and my wife came over to suck on me a little to make me last longer so I didn’t blow my load too soon. At this point I watch my wife climb on top of her friend, they’re making out, my wife doggy and Friends legs spread. I think how hot it would be to fuck my wife while We are all so close together. I climb in between friends legs, my thighs up into hers to spread her legs a little more. I slipped my cock into my wife and fucked her hard. Occasionally friend would pull her towards her and away from me and I’d fall out. Her friend would grab my cock and pull it towards them (her?)… this happened a couple times.. the last time I looked down to reposition my dick in my wife and saw friends slit… right there. Literally pussy tower. I thought how fucking hot it would to swap. I fucked my wife a couple seconds and then pulled my cock out and thrusted into her friend. Her friends pussy felt much different right away. A little wider and deeper than my wife. I scooted down a little and laid my face and body on my wife’s lower back bottom and put my hands on the bed beside friend, beneath my wife. I could hear her moan softly and my wife continued to kiss her. I fucked her for maybe a minute before I found myself thinking how my wife’s pussy was so much tighter than her friends. I thought about switching back and then suddenly found myself thinking about what I had told my wife… about not PIV until we had discussed it. I felt a little guilty as I pulled out quick and then pulled wife off her to lay her on her back and quickly finish up. They went downstairs happily. Next morning my wife tells me friend was texting how she can’t wait to do it again…
