The first pair of real boobs I ever played with belonged to my fourteen year old baby-sitter when I was ten or eleven years old. She talked me into playing doctor while my sisters were in watching tv. she was the patient and I was the doctor. Part of the examination was that I had to check her heart beat. I put my hand on the upper part of her chest but she took it and slid it down until it was cupping her tit and said this is where my heart is. I was shitting myself but stood there as she moved my hands all over her boobs. She lifted her shirt and bra exposing her boobs so I could examine her. She had me squeezing and pulling on her little mounds and little nips for a good fifteen minutes. she then had me check her "down there" as I rubbed her pussy through her jeans. I wasn't even sure what I was feeling at the time but I sure enjoyed it. Looking back I wish she had taken it further than she did.
