"Oh mom, you scared me. I just forgot the time, so it took me a while to get back." Jen said, lying to her mom (Mary) since this excuse had worked before.
Mary was already believing her daughter's excuse, but she noticed that there was something under her skirt that was lifting it up. So she said "Jen, don't lie to me. What have you been up to and what are you hiding under your skirt?" Jen blushed because her mother noticed her cock, even though she didn't know what it was, and ran off to her room. She locked her bedroom door and lay on the bed, getting under the blanket.
Quickly Mary was knocking on the bedroom door saying "Jen, open this door immediately."
"Please mom, don't insist on that. Leave me in peace." Jen said
Mary didn't do as Jen asked, she took the spare room key, opened the door and went inside. "Spill it out young lady, What are you hiding from me?" she said
"This is a private matter mom, you don't have to meddle." Jen said
"Of course, I have to get involved, I'm your mother and I can't just ignore you." Mary said
Jen sat down, looked at her mother and said "But mom, this time there's nothing you can do to help." This phrase seemed more true now that she realized that her mother was wearing a transparent nightgown and was wearing only her panties underneath. Mary's clearly visible breasts made her more excited, making her hard cock pulse under the blanket.
"How can you be so sure? There's no way of knowing if you don't say what's going on." Mary said leaning in front of Jen, making her breasts sway in a way that ended up making Jen's cock pulse again.
Jen didn't want to believe that she was finding her mom very sexy and that she wanted to fuck her. "Please mom, just leave me alone."
"Don't talk to me like that, young lady. I'm trying to let you know what's going on for good, but if you don't want to tell me I'm going to call your dad." Mary said
"No mom, don't call daddy. Okay, I'll tell you what's going on, just leave Dad out of it." Jen disae, because she knew that with her father there would be no way to hide anything anyway.
"This is how you should have done it from the beginning. Tell us right away what the problem is." Mary said
"It's just too complicated to talk about mom, I think you won't believe me if I do. It is better if you lift my skirt and see for yourself." Jen said taking the blanket aside
Mary could see that what Jen had under her skirt was lifting it up, she took the hem of her skirt and lifted it, almost screaming and letting go of the skirt when she saw the 8 inch cock rock hard between her daughter's legs.
"How is this possible? Why do you have such a big dick?" Mary asked
"I don't know, it just grew a few days ago and it's just getting me into trouble. A girl from school found out about my dick and sucked it, but it made her grow a dick too." Jen said
"But you can still get a boyfriend. I'm sure you will find a guy who will accept you regardless of whether you have a dick or not." Mary said
"After what happened tonight I don't think so. I went on a date with Mark thinking there would be no problem and we even started having sex, but then he lost his dick and mine got even bigger. To make matters worse I am feeling more attracted to the female body and my dick gets even harder just because I see you dressed like this." Jen said
"This is a problem. But do you want to fuck me?" Mary said. Jen blushed and just nodded to her mom.
Mary then took off her nightgown and when she was taking off her panties Jen said "What do you think you're doing mom?"
"Of course, I'm getting ready for you to fuck me." Mary said
"But you are my mother, I cannot do this." Jen said
"You can and should do this, just as I am obliged to help you with your needs." Mary said and lay down at the foot of Jen's bed, offering her pussy to her daughter.
Jen got up and stood in front of her mother, then she bent down and passed the tip of her cock through her mother's entrance, she asked "Are you sure this is what you want? What if you end up with a cock like mine? What will dad say about it?"
"I am willing to take this risk, your father will understand." Mary said
Jen then pressed her cock harder, making it end up inside her mother. She then lay down on her mother and fucked her while their breasts rubbed against each other.
While being fucked, Mary had an orgasm and immediately a cock grew on her too, 8 inches long just like Jen's and totally hard.
Jen hadn't come yet, so she continued to fuck her mother, now with her new dick pressed between the two. Jen started to gradually increase the intensity as she felt her orgasm approaching.
Soon Jen came, the orgasm that was certainly the most intense she had ever felt. Her mother also came, shooting her cum that spread as it passed between their breasts and left both dirty.
When the orgasms were over, Jen took her cock from her mother's pussy and lay down beside her. They were both tired, but they were totally satisfied. They then looked at each other, their chests and faces dirty with cum and their soft dicks hanging between their legs.
