A shiver through her told me the cool air was making her uncomfortable. Wearing a black, thin sweater with an ample amount of exposed cleavage and whi...e slacks, she wasn’t dressed for the dropping temperatures.Without a request, I took the blanket and wrapped it around her. It covered her completely, including her legs.“Mmmmmmm...feels nice,” she said as she curled up closer.As we continued to enjoy our drinks and free-flowing conversation, the alcohol emboldened us both. I put my arm around. With her on the inside. She slowly turned around, leaned back against the door, put her hands behind her back and said - "So, how are you going to get my knickers wet then?" "Well," I said as I moved towards her, "let me think now... I could squirt you with a water pistol." "Mmmm," replied Hannah. "What else?" "I could sit you down in a puddle or I could push you under the shower," I said as I got closer to her. "Or... I could... rub them into your pussy for you... or I could lick them with my. Please.. Please let me suck your cock. I.. I need to suck cock s-so bad right now!…’, she said, blushing at her own words. Her eyes were a mix of fear and need. A smirk lit my lips as I shook my head, seeing her husbands car pull up. ‘No.. But I imagine your husband will let you suck his if you ask him nicely.’, Her eyes went wide, looking down at herself, her hands hurriedly tugged the vest over her chest. It looked like an over-strained yarn bikini.. and the button popped almost as quickly. ”She was just staring at me like she was seeing a ghost. “You want to date me? Why?”“Oh, I don’t know, your sweet, kind, easy to talk to, and you are beautiful, Jules.”“You, you think I’m beautiful?”Nodding, I said, “I do. You are so amazing and sexy as hell. Any guy would be honored to walk into our dance with you on his arm and I’m not saying that because you are my sister.”She had a tear in the corner of her eye and then she just launched herself at me, wrapping her arms around me as she.
