Speak translations aren't perfect but accurate enough.
First the real time chat part with a penpal (I removed his answer) :
Have I told you that I've been trying to seduce my nephew's GF since the beginning of family holidays? (Technically he is my BF nephew but as he call me auntie that’s same)
We were in a small lodge separated from the main house.
We've been speaking for an hour about threesomes and she's ok that F/F/M is better than F/M/M because once the guy is out of order, we can still have orgasms between girls as long as we want.
We're both (my nephew's GF and I) on the living room's couch, our legs crossed under the blanket.
She several times teased her bf about his stamina when they had unusual sex.
He is in a soft armchair in front of us. His pants seem to be too small now. My BF is near us, he doesn't speak but he smiles, I think he perfectly knows what I'm trying to do.
My calf touched her panties. She smiled at me then waved a little her hips looking at my nephew.
I think I'm winning.
She was doing it only to tease her bf but that secretly became serious some minutes ago. Her hand is holding my calf pressed against her pussy. I'm making circles with my foot that is making my calf masturbates her.
I'm about to ask who had orgasms today, just to compare and tease my nephew a little more.
Everyone but my nephew put hand up.
She came very silently (I felt it only because I'm pressed against her pussy)
Then she said to her BF that he was the only one in the room to whom I haven't given an orgasm today.
I can't describe the face of my nephew. especially after I added that even in Italy and Ireland I have given orgasms to penpals today.
🏆She just asked me if I would be ok to have a threesome with them.
My nephew objected that we have to ask him if he would be ok too. We both looked at him with greedily lewd faces. My BF patted him on the shoulder then left the room.
Now what happened next:
She said to him "Sorry my love, you're right, we can't just decide to play with you if you don't want to. Come here to get a kiss as an apology."
He got up and went to the sofa. I felt her thighs firmly holding my calf in place. He leaned toward her to have his kiss, she grabbed her by the shirt and kissed her greedily. I was feeling her hand rubbing her wet pussy. Once she freed him from her kiss, she put her fingers in his mouth. He was looking cutely panicked.
"But, my auntie is" he started to say when she finished his words "masturbating me under the blanket." He looked at me and I added "In fact she's masturbating herself using me. You know that I don't take the initiative to have sex with someone in a relationship." He made a step backward "Wait a sec girls, I need to breathe."
She removed the blanket from her and took off her clothes, I did the same, keeping my lingerie then threw my shirt on him "As you prefer. But I'm not sure you can breathe normally in front of this" I said while shaking my boobs with both hands. He started to shiver "Yes, I can…" she finished the sentence again "hold your load ? I don't think so." He instantly came in his pants.
She didn't give him a break. "Now that's done, we can play seriously" She took off his clothes in no time. He just said "OK, I'm yours."
She pushed him back on the armchair and started to clean him up with her mouth. I came between her legs then I licked her slowly. She was already close to a second orgasm. She sat on him then orgasmed from taking him in. She rode him a little then after having freed him, invited me to clean him up again. I licked her cyprine from all over my nephew's cock.
Once done, we both (girls) were lying down on the floor and she told him to join us only when he will be able to blow another load. We played together in front of him, she was loving to learn lesbianism and she was a very good student.
I skipped the details because I was too wild to remember them well.
After about half an hour, he joined us. He was still a little shy and he was only caressing us while we continued to play together. Then quickly, we put him on his back and we spent time licking and kissing every inch of his skin symmetrically, both avoiding his genitals.
Once done, she asked him to stand up in front of me on my knees, she grabbed his balls from between his legs and pulled them back until his foreskin no longer covered his glans. She asked me to take it between my lips then she masturbated his cock whispering in his ear but I wasn't able to hear what. I stayed here, massaging my boobs and keeping eye contact while she was emptying him in my mouth.
End.
