With a question.

"Melissa, honey, does Helda have blonde hair?"

"Yes Mom, why?"

"I'll tell you in a minute. How big was her cock, did she tell you?"

"Yeah, she said it was n-nine inches, M-Mom, what a-are you doing?"

Melissa's mom Sandra was rubbing her daughters pregnant midriff, her hand snaking its way down to Melissa's already soaking thong.

"The reason I asked sweetheart, is because when I was your age, I had a classmate called Helda. We all wondered why she wouldn't shower with us, it wasn't until she and I were alone one night, everyone else had gone to a party but we weren't feeling it, so we stayed home. Helda and I got a bit tipsy and she confessed to me that she was a shemale. Do me a favour, do you have her number?"

"Y-Yeah, in my phone contacts..."

Giving Sandra the phone, Melissa moaned as quietly as she could as her mothers fingers found her sopping wet gash.

"Hello Helda, it's Melissa's Mom. I don't know if you remember me, but you and I shared a very drunken night, roughly nineteen years ago, when you confessed to me as we got drunk that you were a shemale."

Melissa gasped as she put two and two together, Helda had gotten her Mom pregnant at roughly the same time that she was conceived.

"So you do remember, well, it would seem that history has repeated itself, only this time it's Melissa who you've seduced. Do you know I never took another lover after I had Melissa, none of them could measure up to you. You have our home address, not Melissa's campus one. You do? Great, be here in an hour, I'll get warmed up for you..."

Just as soon as she'd ended the call, Sandra got down between her daughters legs and pulled her soaking wet thong off, sticking her face in between her daughters spread legs and eating her pussy.

"Oh God, Mom, w-what are you doing?"

Sandra didn't respond, instead concentrating on eating her daughter out, the taboo act turning her on something chronic, her jeans were getting wetter and wetter as she anticipated fucking her one true love, the one that got away, Helda.
