My friends younger sister is flirting with me more and more. This all started when we helped her to move house after a relationship with her ex boyfriend ended. She was very thankful to me for helping out and we kinda got chatting from there. First it was a few messages just asking how I was and what I was up to. This progressed to talking more and then her sending some quite revealing pics to me and asking what I thought and for my opinions. Interested in hearing your thoughts on this and hearing your stories of potentially inappropriate things like this…
