So this has happened just the day before yesterday. A [f]riend (let's call her lisa) of my gf(tina) as invited us to her at home. She lives with her brother and their parents. It was her brothers(mike) birthday and he has just turned 18. I've met him a few times, but my gf knows him for about 10 years. He was out with with his friends but would probably just be at home around midnight.

We've talked about lot of things, and Lisa has mentioned that her brother is still a virgin and that he had always a crush on tina (which she knew btw). Lisa jokingly said, that tina should just take his virginity. My gf has immediately responded "i will do it it". Lisa's jaw was dropping and she said: "it was just a joke", but tina just answered: "don't care, I will do it and she (pointing to me) will do it to".

So Lisa has texted him, that he should tell her, when he comes home so that she knows, if she should turn on the security system or not. Which was of course a lie. It was just to know how much time we have. Around 23:00 he texted her, that he will be at home around 23:45.

We've decided to wait in sexy underwear in his bed. I didn't wore a bra, so I've borrowed a sexy matching one to my panties from her. Thankfully we are having the same bra size. Tina on the other hand was already set.

Lisa went to her room/bed. Tina and I went to Mikes bed and started to make out. When mike came in we were both already fucking horny and wet. So he could "come in" as soon as when he is ready. His reaction however was unexpected. He has just asked in a serious way "what we are doing here". It really didn't click first in his head.

So Tina put my my hand in front of her and 4 of my fingers up. "Its your birthday, so you have now 4 choices:

1) you can throw us out (and put a finger down) 2) you can sleep on the couch and let us sleep here (and put a finger down) 3) you can watch us having lesbian sex (and put her mouth over my finger to suck a moment on it before she put it down) 4) your bed is big enough, you could also remove your clothes and join us (and she sucked on the last finger a little bit longer)

So what is it?"

His face got so red!!! It was kinda cute to be honest xD.

It took him a few seconds before he could answer, but he went for the last option. Tina kissed him and we took of his clothes. He was already hard. He was about average size, but to our surprise nicely shaved. We've started to tongue kiss, while we put his dick between our mouths. Tina went further and started to blow him. I went up to him and took off the bra and put his hand on my tits. He squeezed and played with them. We've exchanged a few kisses and tina asked mike, which pussy he wants to enter. He asked for hers so she undressed completely and begun to ride him. It didnt take long until he came in her.

After that mike and I started to please her with our fingers&mouths until she came too.

Next was mz turn and Tina has decided that he should take care of mz upper bodz and she will do the lower body. Mike did really a god job with playing with my tits and sucking on them, while tina pressed her mouth against my lips and sucked&licked me.

I didn't realized i first, as I was close to orgasm too, but mike told tina to move to the side. I was just a little bit confused why tina did stop so suddenly. then Mike has tried to put his dick in me, but he had some troubles finding the entry port. I put my hips a little bit higher and tina lend him her hand for guidance. When he was finally in me he started to fuck me. His thrustswere not fast, but hard in the beginning. After a while he went faster too. Tina helped him a little bit more and fingered my clitoris in the meantime. the orgasm I got from this was really intense and mike did cum too from my contractions.

After that we three went to sleep.

In the morning i woke up, because they both were fucking again right next to me.

I've turned around and kissed tina and started to rub her clitoris, while he was banging her.

When they both were finished we dressed up and went downstairs to lisa. Lisa had already prepared breakfast.

She asked mike, if he had a good night.

Man that guy went from white to red so instantly xD
