With your roommateturned into a woman, it is quite hard to control yourselves. You go behind the next corner to fuck around. You undress and realize
"Fuck, how do we do it?"
"What do you mean?"
"I mean without a dick!?"
"Just rub me there"
You feel a finger entering you from behind between your two legs.
"It is open, what now?"
"I don't know use your finger! Deeper... deeper!"
After a while, you two realize it isn't working, You don't know how to satisfy a female body without a penis.
"I need a dick"
"Where? INSIDE you or on you?"
"BOTH"
