I'm really sorry to be so negative about Jenni's mum. Of course, I write with the benefit of hindsight and you will see why. Even so, I don't think I ...m being too unfair to her...We delivered Jenni and Martin back to Reminder mid afternoon and stayed on board until the first punters (sorry, passengers) arrived, when we left them to it.It's almost axiomatic that British public holidays have foul weather, but every so often we have a warm, dry Bank Holiday weekend. Not often, mind you, but on. Uh... sorry aunty Bronwen!" I stammered as I exited the bathroom, cock still in hand.Mum, having heard the commotion, came out of her bedroom and saw me standing outside of the now closed bathroom door, my erect cock still sticking out of my shorts. "What are you doing?" she hissed at me."I had to pee." I whispered, tucking my cock back into my shorts and moving down the hall away from the door. "I didn't know she was in there."For a long moment mum didn't say anything. Then she got a smile on. Moving behind me, he started fucking me doggie style. Like a rutting bull, he fucked me hard and slapped my ass hard with his hand. His energy had me cumming again in no time.Then he pulled out and said, "Time for me to tap your sweet white ass."I didn't say anything, but I'd never had anal sex before.He rubbed something on his cock and up my ass with a finger. Then I felt the head of his cock pressing against my rose bud. Slowly he pressed with his rock solid cock. I could feel my sphincter. Can I see?" Some would see this request as being wrong from a mature woman to a 16 year old, but I was a typical boy and knowing where this was going said, "Yes." Still I nearly jumped when she reached out and put her hand unto my crotch. Despite my nerves my cock immediately responded and grew hard under her hand. She looked straight into my eyes and said, "What's this you dirty boy!" before I knew what was happening she had knelt down in front of me and was undoing my belt, then my trouser.
