The weekend cabin

My sister just split up with her boyfriend and needed some time away. So, I took her to our family get away cabin in the hills.

My 16-year-old sister Tammy had just split up with her boyfriend, and he already had another girlfriend. Tammy wanted to go around to his place and throw eggs at his place. I walked in on her pissing in a plastic bag that she was going to toss at him.
She needed a break, being her big brother at 18 I had a license and a car. So, I took her to our family holiday house in the hills 120KM out of town.
We got there and unpacked the car. Later we had dinner and Tammy managed to find our parents wine stash. She opened a bottle and had a couple glasses of it.
After dinner she looked like she was about to burst into tears. S o I gave Tammy a hug me and started crying on my shoulder. Tammy was a little drunk and she started confessing things about or relationship with her boyfriend Peter.
About the sex and the number of times and places she sucked him off. In public toilets, at his place.
She told me I had walked in on them four times just after they had finished and had swallowed his load before she could answer me. One time I had walked in on them watching a movie Tammy had a blanket over her legs she was naked from the bottom half and had cum leaking from her pussy.
Tammy told me she really enjoyed giving head. Making a cock swell up in her mouth the feeling of the head on her tongue, the noises and moans the guy gives off before during and after he cums and she even enjoyed the taste.
I knew she was a little drunk even before she started touching my crotch or before she got to her knees and pulled my cock out. You know when you tell yourself you should stop what is happening but for some reason you just stand there and let it happen.
I mean it is only a blow job it is not like she could get pregnant from that. I quickly realized how good she was at sucking cock. There was no way I was going to last very long looking down at my sister's her lips wrapped around my cock, her face moving up and down the shaft. I would have lasted longer if I had not kept looking at her face. I shot my load and she caught it in her mouth she even showed it to me before she swallowed.
We kind of went away from each other I played a game on my computer. Tammy went to have another drink. I went to bed a bit later. I was thinking about that blowjob Tammy had given me and started having an erotic dream. I was on my back, and a naked woman was on top of me riding my cock. As I started cumming I woke worried about sleeping in wet sheets again. Only to realize my sister was on top of me calling me Peter and telling me she still loved me. She didn't mean to cheat on him with his sister Molly.
Next thing she lay top of started cry and kissing my face until she fell asleep.
The next morning, I woke up with my dick still in her. I rolled her off of me and covered her naked body with my blanket. Then I used the toilet had a shower and got breakfast ready.
She staggered out naked dry cum in her pubes and asked, "Did we?"
I responded with "We will talk about it later, once you are a bit more awake. I think you need a coffee.
When we did talk, she admitted she drank too much and had no idea what was happening and I admitted I only woke up and realized it was real as I was cumming.
At one point Tammy said, "You know they say the best way to get over a breakup to have sex with the next guy you meet."
"Who says that?" I asked.
"Normally the next guy you meet." she said with a smile.
Tammy was about to start drinking more wine and I tried to stop her, I said "Didn't we lose a bit of control yesterday after you drank too much.
Tammy looked shocked "What did we do that was so bad?"
"You sucked me off and then fucked me in my sleep."
Tammy the suggested she suck me off two or three times and hopefully my balls will be too sore to fuck later.
I had no way of arguing with that and I sat back and let her suck me off. now and twenty minutes later and twenty minutes after that. We hung around the house all day I was only dressed in my boxer shorts, and Tammy was wearing a matching pair of lace panties and bra. Her panties were camel toed with a few pubes hanging out the sides and I could see her nipples through her bra. Each time she sucked me off she took her bra off before she started.
That night I climbed into bed and Tammy got in with me. She started stroking my cock and I got hard she climbed on top of me and started riding me. I could feel myself wanting to cum, but nothing was happening and I lasted a lot longer. But even so I still managed to cum again in my sister.
The next day we cleaned up and went home. On the way home Tammy told me a couple of more weekends like that, and she may finally be over Peter?
