I was in my hot tub one night just relaxing, then I heard my sister-in -law asking if any one was home. I said I'm in the hot tub. She came by the hot tub and said "can I join you?" I said "come in".

She took off her clothes and her body was great. My big 10 inch length started to get hard. She came into the hot tub and reached for my length.

She said I never felt a length so big.

She asked if she could suck it. I just grabbed her head and pushed it to my length. She started to toy my balls and stroke my length. She took my big length into her mouth and started to take more of my length into her mouth. She kept takeing more and more of my length into her mouth untill she had all 10 inches down her throat. She kept sucking and toying. She could tell I was ready to cum, she went faster and faster untill I shot my hot cum down her throat. She swallowd all of my cum. She said we could get together again soon.
