Meg and Sarah are twin sisters, both are 18 years old and are seniors in high school. Unlike most women, they have both male and female genitals, a fact that is known to everyone at their school.

It's early in the morning and Meg woke up with her cock totally hard. She got up and watched the little of her reflection that you could see in the mirror due to the darkness in the room, seeing the girl with long black hair and big breasts. People close to her said she had her mother's body, but her father's face.

With her cock hard and demanding some relief, Meg looked at the other bed in the room where Sarah, her twin sister was sleeping. Meg briefly observed her sleeping sister, the sister who had a body exactly like hers except for her blond hair (She dyed her hair to be easily differentiated from Meg) and noticed that Sarah also had a hard-on.

Meg needed to fix her erection but she didn't want to wake Sarah up, so she decided to go masturbate in the bathroom, but she tripped over the clothes that had stayed on the floor and fell on the floor.

With the noise that Meg made when she fell, Sarah woke up and said "Meg, what are you up to? Why all this noise?"

"I'm sorry, I was going to the bathroom to masturbate but I tripped." Meg said

Sarah realized that she too had a hard-on, so she got up and turned on the bedroom light. After that she saw the time and said "At this time we won't be able to go back to sleep before going to school, so why don't we relieve ourselves together?"

"Come on, I couldn't wait any longer." Meg said

Meg sat on the bed to masturbate, but Sarah had other plans and went to sit on Meg's lap.

Meg held Sarah and said "Take care Sarah, so I can accidentally fuck you."

"But I want you to fuck me." Sarah said

"I cannot fuck you, we are sisters." Meg said

"And what's the problem with that? As long as none of us get pregnant, that's fine." Sarah said

This convinced Meg to accept and Sarah sat on her cock, lowering slowly as she was penetrated. Once with her cock completely inside Sarah's pussy, Meg started to move in order to slowly fuck her sister, who was jerking off in the meantime.

The sisters' sex was interrupted when their bedroom door was suddenly opened, lhey looked at the door and saw their mother (Rachel) entering the room and catching them in the act.

They tried to find an excuse, but Rachel just smiled and said "You don't have to worry, you are old enough for that. But be careful not to end up pregnant."

"OK mom." Meg and Sarah said

Even so, they would wait for their mother to leave the room, but instead Rachel took her hand to her cock, which was also hard, and took it to Sarah's mouth saying "Come on Sarah, try your mom's cock too."

Sarah did as Rachel asked and started giving her mom a blowjob. At this moment Meg returned to fuck her, now with more desire.

As they had started earlier, Meg came first and shortly afterwards Sarah also came. Rachel was not satisfied and jerked off until she came too, getting Meg and Sarah dirty with her cum.

At the end of the orgasm Rachel said "Sarah, you're not as good at sucking cock as your dad, but with more experience you'll be great at it."

"Give her a discount, mom, you know it's her first blowjob." Meg said

"I know. But now you better take a shower soon or you're going to be late for school." Rachel said

The twins then showered together and went to the dining room, Rachel was waiting for them with John (father) and Julian (younger brother), where they had breakfast before going to school.
