I got to watch with benifits 2

It had been 4weeks since mum had helped me cum and mum and dad went away for a week to there holiday house so i stayed home by myself. I was horny all the time as i wanted to see the neighbor as much as i could.
Mum and dad left on a Wednesday and they told me they would be back on the Sunday in the arvo.
Every morning i would check the neighbor's pool area to see if they were there but nobody was there. I would also check in the arvo and night but nobody was there.
I would go around the house naked all the time and most of the time i had a hardon. I even tried going outside and i found it was a turn on as well.
on the Saturday night i checked the neighbor's pool around 9.00pm from the back room and i saw the light on in the pool so i stayed and watched. I saw the young woman in the pool with a guy. As i watched i saw them cuddling and kissing in the pool. It was not long and they got out of the pool - naked - When they got out they kissed and cuddled again. I had a hardon and started jerking off. It was not long and she moved down and to my surprise she put his cock into her mouth .It is the first time i had watched a female suck a guys cock. I had to stop jerking a couple of times so i did not cum and i wanted to watch. It looked so good and she put his cock just about all the way in. After a while she stood up and kissed some more. It was not long and he moved down and ended up with his mouth on her pussy. It looked like she cum and he stood up. She turned around, bent over and he fucked her from behind. I could not help myself and i cum. I cleaned the mess up and then went to bed. All i could think about was what i had seen.
The next day nobody was in or near the pool so i cleaned the house as mum and dad was coming home the arvo. Mum rang me about 4 in the arvo and told me they would be home late so i should go to bed.
I went to bed around 8pm after a shower and all i could think about was what i had seen in the pool. I laid on top of the bed - naked and jerked off just thinking. After i cum i went to sleep. I did not hear mum and dad come home.
The next morning i woke up about 8.30am just as mum came in my room to check on me. She sat on the side of my bed and talked about what i had got up to while they were away. I told her what i had gotten up to and all about what i had seen on Saturday night. Mum asked for details so i told her. Then i remembered i was on top of the bed naked with mum sitting beside me. I also had a hardon which she kept looking at.
Mum turned around a bit and took hold of my cock and then started jerking it. She stopped for a bit - stood up and dropped her dress and all she had on was her undies. She sat back down on the bed up a bit closer to me and started jerking me again. It felt so good someone else jerking my cock. I got a bit of nerve and reached over and put my hand on her boob. It felt so soft and her nipple was so big and firm. I moved my hand down and put it on her pussy on top of her undies. It was wet and all of a sudden i let out a big shot of cum. Mum slowed jerking me and they took her hand off. She lent forward, kissed me on the cheek, stood up and then told me not to tell anyone. After mum left my room i got a hardon again so i jerked off and as i was about to cum i saw mum standing at my door - naked - and watched me cum.
