I went alone. I sat under the tree. I started to talk with my friend on the phone. While i was talking to him the same girl came there for toilet. She... had a bucket of water in her hands.I thought that this was a very good opportunity. I did not want to miss it. I cut the phone and switched it off. I hid behind a heap of grass. Them she searched for he any one is there looking at her. As there was no one she sat down and started doing toilet. As she lifted her gown i saw her beautiful ass. I. Come on Charley, I need to check your prostate gland and get a sample of your prostate fluid. Here, lean over the table for me and spread your legs as far apart as you can." Turning my head sideways, I watched Diana pick up a large tube of K-Y ointment. "Have you ever had your prostate massaged before, Charley?" "No, Diana, I haven’t. No one has ever put anything except an anal thermometer in my asshole before." "Just relax for me, sweetheart. I won’t hurt you, I promise." Diana coated my hole. “Give me a little time and I’m going to use you in ways that I always wanted to. I have to run an errand and I will be back to have my way with you.” At this I could only wonder and worry about what she had in mind.“But honey, you can’t leave me like this alone, please let me out.”To this she went to the closet and pulled out the ball gag. She leaned over me so as I could see the cleavage of her breasts and put the ball gag on tighter then she usually did. To this I just could mumble my words.. She dug her tongue into his piss slit and tasted the remains of his dried piss. She had found she loved all the tastes his cock provided her. Maybe, just maybe, she’ll ask him to let her taste his piss sometime. When she first seen it in her father’s porn she thought it was gross, but, now after tasting it off the end of Tim’s cock, she was developing a desire to taste it. Tim then hit a bump in the road and it sent his cock deep into his sister’s throat making his cock feel so good buried.
