I ws fishing and sitting by the stream in our woods and two guys and one heavy girl came by. They fished next to me, and the girl was chatting with me. I chatted friendly like, but when the guys went to leave, she stayed. She kept getting cozy, and touching my privates, then she started to get undressed, and I let her underess me. Well she straddled me and I had sex with her doing the work over me.
