My Trans Girlfriend

My girlfriend is a 27 tear old beautiful M2F transexual. Very passable with a hot body. She made the decision to keep her original boy parts. Due to the hormones she has difficulty getting an erection. Her doctor helped her out with that and prescribed an ED substance that could get an elephant hard. She actually has a nice sized cock at 7 inches and fairly thick. About 1, maybe 2 times a month she gets a bout of her male urges. She starts popping her ED meds like chicklets and I know I am in for it. I spend a couple of days getting my ass fucked constantly until I am too sore to take any more. Then I have to give blow jobs and hand jobs until she is satisfied. This past weekend was a good one. She fucked me 4 times Saturday and woke me up Sunday morning to take it again. After the morning I was pretty sore. Sunday I gave her 3 blowjobs. It was a great weekend!
