I came buckets of cum, gallons of cum as she gagged and choked on me, her throat muscles contracting and milking my cock for everything it was worth. ...After a solid thirty seconds of heaven, I finally finished cumming and slowly slid my now soft penis out of her throat and mouth.Audrey was so utterly spent from the intense sex, that all she could do was to sit back on her haunches, leaning against the 4-wheeler and gasp in air. I picked her up and pulled her panties and jeans back up and put my. I pretended to punch her in her face but didn’t flinch so she must have been blind.With a tie around each ankle I parted her legs as wide as I could. She must have known what I wanted as she put her weight on one foot then shifted her other foot as far apart as she could then did the same to her other foot. I tied off the loose ends to the door hinges pulling each tie as I did making sure her legs would stretch out no more. I stood back and admired my work. She was stood in a very strict spread. So the dare - to start with we all went upstairs to Dave's sister's bedroom, (she and her parents were all away on holiday, so it was just us there). Ben looked through Dave's sister's wardrobe and lingerie drawer and threw some things on her bed. Dave's sister is in her twenties and very hot (her name is Bianca by the way). She is always wearing sexy clothes when we see her out. I was then told to put the clothes, which were on the bed, on! I protested but this was now my dare and I didn't. It was him and her and either a bottle of wine or beer. It was his treat. Either way he was there to entertain her. They spent the day together. Talking about life and potential love for some reason he told her he hadn’t found the girl for him. As they talked they drank some more. By late afternoon they had run all topics out. “Yeah, I sure miss being in love not that I have been,” he told her. “I have no idea why I’m saying this but I miss being with a woman. I miss holding her and cuddling.
