More....our first time was not planned at all, we'd never even talked about any thing like this.
It was about 4 months after our first time that it happened again, same guy. Same deal and same huge amount of guilt after. But our sex after was incredible. We kinda talked about doing it again without admitting to each other hot exciting it was. After the third time we called him, invited him over, had a short talk about what we all did and how we liked it. Slowly worked up to him joining us more often.
I'd say first 10 or so times they would mess around then have sex, he'd leave then she and I would enjoy each other into the night. I stayed dressed while I watched. Took 20 to 45 minutes tops. We have a recliner chair in our bedroom, I just sat there watching. They would finish, he'd get dressed, she always put one of my dress shirts on and waked him to the door.
Night went like usual, I strip, jump into bed waiting for her to return so we could get it on. She comes into the bedroom and he's with her, I'm like WTF ? My super cool wife politely asks if they can go once more. I get out if the bed, slip my shorts on and sat there watching their 2nd round. They got done, he left and she fucked me silly. From that night on they went twice befor he left. It was even hotter for all 3 of us.
We had told him how we liked the sex after he was gone. One night after they finished he says...why don't you guys go while I watch? I was a little unsure but it went well. He was hard again from the minute we started, I finished then he went again. We just kinda progressed to him and me twice each.
We were really comfy together. One night, after 2 rounds each, she's down stairs kissing him goodbye for a little longer than normal, no biggie really. She finally comes back to bed, we start to cuddle, she tells me he fucked her in the livingroom before he left.
That led to him, me, him then me....then another from him in our bed.
It's a very very hot night for us but there's still some guilt for both if us.
