About fifteen minutes later John came stumbling out to the kitchen. He had a shit eating grin on his face. "What?", I asked. " Staci could barely keep her eyes open while we were doing it, she passed out out before I finished." John laughed and said, "I kept going, she'll never know." He made himself I drink and preceded to pass out himself halfway through it. I know from past drinking outings with him that he probably wasn't moving from that spot until morning. I sat there and decided I had to try and get a look at Staci's naked body.
I nervously crept down to their room. The door was ajar and I went in. The bedside lamp was on and I could see Staci laying on her stomach on top of the sheets. He hadn't even bothered covering her up. She was only in black panties and I started getting hard. I took my phone out and got some shots of her ass. I desperately wanted to see those tits, but couldn't decide if I should try to roll her over. I walked to the side of the bed and give her a little shake, nothing. Looking down her mouth was slightly open and inches from my crotch. I went from trying to figure out how to roll her over to pulling out my cock and rubbing it on her open lips. I slid it in her mouth a couple of inches then back out and back in again. It wasn't like getting a blowjob, but I was rock hard and about to burst. I started recording while a slowly fucked her mouth and rubbed her panty clad ass. It was now or never. I removed my cock from her mouth and got behind her. I slipped a finger in her pussy and it was still wet from earlier. I couldn't wait any longer. Gingerly I laid down on her back, propped myself on my elbows, pulled her panties to the side and slid up into her. Oh my god it felt like heaven. I enjoyed her warmth for several seconds and then started fucking her. I was trying to take it easy, but my rhythm was picking up until i was slamming into her. I had the best orgasm I'd felt in years and filled her up with my seed. Collapsing on her back I suddenly came to my senses, grabbed my phone and went to my room.
The next morning I woke with a raging hardon thinking about what I'd done with Staci. I waited until Amanda woke up and pushed her head down to my aching cock. She reluctantly started giving me head. Amanda had no idea she was tasting Staci's pussy juices instead of hers on my erection. Watching her mouth go up and down and her tongue swirling around the tip having no clue I'd busted a nut in Staci hours earlier was to much for me. She made me cum in minutes and like a good girl swallowed my load.
As I was heading to the kitchen to get some coffee I passed John and Staci's room. Staci was pissed that he'd come in her. He swore that he pulled out and finished on her back and cleaned her up. Oops. The rest of the trip was fun although I never did see Staci's tits. I did manage to steal the black panties from our special night.
About two months later Amanda told me she was pregnant. I went to share the news with John and when I told him he got a big smile and said "Staci is too!"
