A couple days later
I walked in the kitchen and Autumn was doing dishes. She was wearing a sports bra and leggings, our parents were upstairs.
My plan was to jerk off onto her ass. She was wearing headphones. I got behind her and got my dick out and start jerking slowly. Then I thought fuck it, I grabbed her hips and started grinding her ass. She tried to pull away but realized she wouldn’t be able to so she stopped trying. I put my cock in between her thighs and reached around and gripped her right tit. Then I heard our mom coming down the stairs so I opened Autumn’s leggings and blasted her ass with ropes of cum. I grabbed a coke from the fridge and walked away.
It was summer break and Autumn and I would sleep outside on the trampoline sometimes during summer.
We got pillows and light blankets, got everything through the net and got our spots. I played on my phone until I thought she was asleep. Then I took my shorts and underwear off and went over to her. I got in big spoon position. I then realized she was only wearing a sports bra and a thong.
I was unexpectedly very tired at this point so I just put my cock in her thong in between her cheeks and put my arm around her. Then fell i aleep.
I woke up a 4 hours later and she was awake on her phone, on her back. I looked and she was texting her boyfriend. I reached our and put my hand in between her legs. She was still wearing her thong. She gasped then said she can’t do this right now. So I got on the opposite side of the trampoline of her and slid her legs in between mine and her feet slid right on to my cock. She started giving me a foot job while she sent titty pics to her boyfriend.
A couple minutes later i said I was about to cum, so she got up and put my cock in her mouth and took my whole load and swallowed it. Then licked it clean.
