Finally learnt how to fuck! Stepsister gets XXL cock!

It never ceases to amaze me how quickly a cosy evening can escalate. I was sitting on the sofa with my book and suddenly my stepsister was standing next to me in her mega domina outfit and snappily told me to put the book down and that she had a surprise for me. A little surprised and taken by surprise, I reflexively followed her request and was really surprised that she actually brought me a man to practise on. She had seen my videos and wanted to finally teach me how to fuck properly as a woman and how to satisfy men properly. I was still completely perplexed by the whole situation but also really excited and nervous about what she was going to do to me. She was already moaning while she was blowing me and asked the guy to fuck me properly in the throat. OMG I've never had a cock so deep and hard in my throat and I was almost reaching my limits. After a short breather, it went on even harder, my pussy should finally be fucked really hard and the two were really not squeamish with me.
