I guess we were a 'normal' family, I had a sister, Rachel, who was almost 2 years older than me and my parents did all the usual parent stuff with us - sports, vacations, etc. Rachel and I got along like most siblings, sometimes we fought, sometimes we did our best to get the other in trouble but overall, we were pretty good friends who could trust each other when we had no one else to talk to. It was just us, none of our grandparents were alive and neither mom nor dad had any siblings so we'd grown up without any of the large 'family get togethers' that a lot of people had.
Over the years I'd gotten a few accidental glimpses of Rachel - a loose t-shirt without a bra, a towel that slipped or me walking into the bathroom without realizing she was there and I'm pretty sure she'd seen me nude or partly nude a few times but neither of us made a big deal out of it and by the time she was almost graduating high school, we were both enjoying sex fairly frequently with our respective dates.
Fast forward a couple of years - I was 19 and still living at home and in college but had been trying to save money to get a place of my own. I'd been doing general labour for a construction company but they didn't have enough work so had just laid me off. Rachel was 21, just finishing university and renting the basement apartment in a house so she could have a bit more freedom than at home. Our parents weren't crazy strict but expected us home by a reasonable time, no parties, no dates spending the night, etc.
Mom and dad had always wanted to tour to the east coast and had decided this summer would be the time to do it so they'd rented a small motorhome. They were planning on taking about 3 weeks to do it, maybe more if they stopped somewhere for a bit. Mom had a small, home based accounting business and dad was an assistant manager at a manufacturing company so with a little planning they were both able to take that much time off. That was fine by me because it meant I'd be able to have a bit more fun, hopefully including a lot more sex than usual with my girlfriend Becca. We'd had been an on-again/off-again couple since high school who really enjoyed the sex. We'd broken up a few times but always gotten back together again, sometimes only for a good fuck when we were both horny and single. Right now, we were 'on' and had been for a while, enough that I was really starting to think that we had a potential future as a couple.
Saturday
All the arrangements were made, I had a copy of their route so early on Saturday morning, mom and dad left with the usual hugs and cautions of 'Mark, remember - no parties and if you need anything just call.' they headed out.
I doubt mom and dad were even on the highway before I was texting Becca that I had the house to myself. The reply I got back told me the next few weeks were going to be fun... "see you in a few, how about you get naked so I can climb on you when I get there?"
That sounded great to me and it wasn't long before Becca was walking into my bedroom. When she saw me laying there naked and already hard, she quickly stripped and moved up onto the bed. I was expecting her to start riding my cock but instead she moved up even higher so she was straddling my face. "Lick me until I cum" was the last thing I heard before her pussy settled against my tongue. I loved the feel and taste of a pussy with my tongue so I happily ate her until she came not once but twice. Just as her second orgasm started, she quickly shifted so she could impale herself on my cock. The sudden change from tongue to cock seemed to intensify her orgasm and she came several more times as she rode my cock. Eventually I shot a huge load into her pussy. When she felt me spurting into her pussy, she leaned down and we kissed. "Damn you always make me cum so hard!"
I was kind of hoping she'd be able to spend the night but apparently her parents had some sort of dinner thing planned so she had to go but promised we'd find a way to spend a couple of nights together before my parents got home.
Sunday
As luck would have it, I got a text from her the next day saying her period had hit early and she'd be 'out of commission' for a few days. I'd learned long ago that she often had really bad periods and would often end up just taking pain killers and lying in the bed so I wasn't too surprised but hoped this one wouldn't be one of the bad ones. Unfortunately, it was so I knew it would likely be almost a week before we'd be able to get together again. I spent the rest of the week watching porn and enjoying a few good orgasms along the way. By the time Saturday rolled around, I was really happy to get a msg from her that not only would she like to get together that evening, she should be able to spend the night because she'd told her parents there were a few of her friends getting together for a sleepover.
Saturday
I suggested I order pizza and she said that'd be great. Becca got there just past 4:30 and looked great in a low-cut top and short skirt so after some quick kissing and groping, Becca looked at me and said, "Mmm, I can feel you getting hard already. How about I take care of that before supper and you can take care of me after supper?"
I wasn't sure what she meant by 'take care of' but I was pretty sure I'd enjoy it and I was right. When I nodded, Becca had me stand by the couch then after undoing my pants and pulling everything down, she told me to sit. Once I was sitting, she knelt in front of me and proceeded to lick and suck my cock until I exploded in her mouth. After a quick swallow, she smiled and said, "Who says you can't have dessert first?"
A few minutes later the pizza got there so we grabbed a couple of drinks and ate. As soon as we were done and things were cleaned up, I told her it was her turn to sit and enjoy so with a big smile she lifted her skirt, pulled off her thong and sat back on the couch. Becca was one of the more vocal women I'd been with so as I licked, kissed and nibbled on her pussy, I was constantly hearing moans of 'yes', 'feels good', 'right there', 'oh ya' and lots more. After about 5 minutes she had a small orgasm and when I was pretty sure she was close to another one, I focused on her clit while sliding two fingers inside her pussy and curling them up so I could stroke her g-spot. The reaction to the combination was immediate; her hips arched up, she started moaning even more and about 15 seconds later she started cumming. She usually came pretty hard but this was a really strong one, maybe because it had been a week since we'd had sex. When she finally relaxed, she looked at me and said, "that was awesome...how about a bit of porn before going to bed?"
That sounded like a great idea to me so we spent the next hour or so taking turns finding different porn clips to watch. By the third or fourth clip, our clothes were coming off and by the time we'd watched a few more, we were laying naked on a couple of sleeping bags I threw on the floor. She was always super horny coming off her period so I suggested a game we'd done a couple of times before. Basically one of us would pick a video then the other could randomly pick a starting point and that's what we'd do until a 2-minute timer on my phone went off. She quickly agreed with the usual condition that either of us could say no if it wasn't something we'd want to do.
I figured that was a good compromise so we spent the next couple of hours watching clips and movies. I can't remember everything that we did but I know I got lots of head, Becca had her nipples and pussy licked, we fucked in lots of different positions - spooning, missionary, doggy, bent over the couch, standing and likely a few others. The highlight of the evening was when I picked a starting point and at first it looked like a guy licking a pussy from behind but then we both realized it was a guy licking a woman's asshole. That was something I'd never done and I don't think she had either but when she looked at me and I nodded, she got a big smile on her face and knelt on the bed. I moved behind her and tentatively started licking around, across and finally using my tongue right on her pucker. She was moaning about how good it felt and I was surprised at how much it actually turned me on too. When the buzzer went off, I gave her one last lick before she clicked on a different part of the movie. I quickly realized it was an anal scene and expected Becca to veto it because she's always rejected any suggestion of anal sex but instead, she looked at me and asked if I could back it up a bit. I figured that was better than an outright 'no' so I backed it up to where he was just starting to enter her ass. I looked at her to see if she was going to say yes or no but she instead she kissed me and said, "can we watch it for a bit first?"
