This happened about 5 years ago now when I was in the midst of a nice single period. I’d got back in contact with my ex, actually my first, and we had become good friends again.
She was recently single and so i suggested we get some drinks with other friends. Perfectly innocent at the start! So after meeting at a pub we were drinking and enjoying the company when she asked me if she could stay on my sofa because she was still living with her ex at the time and wanted a break. I of course said she could.
At this point let me describe her, 25 with short blonde hair and just gorgeous D cup tits, she had pale skin and these perfect pink nipples. As maybe the first pair I ever saw they really set a high standard.
So the evening progressed and we decided to leave and there was maybe some tension, although in hindsight as I’m not sure I felt it at the time.
