Helping my lesbian aunt

good as the title says I have an aunt (Sofia) who is lesbian, very pretty with good body, good breasts, better buttocks, although since she's my aunt I had never seen her with eyes wanting to take her, she is years older than me and when this happened I was 18 years old and she was 22, well first I have to say that we are very good friends since we were little and then I was the first to find out she's lesbian and meet her current partner, sometimes she would let me stay at her house as my university is near her house, but well I'll start with the story.

It was Saturday and I had class, so as usual on Saturdays I got up from my aunt Sofia's couch, Erika her partner was leaving for work, Erika is a normal girl secretary to some executive or something like that, with good body like my aunt but better breasts, she left for work, my aunt was preparing breakfast, I got in the shower, came out and had breakfast with her

-What will you do after school?- I asked my aunt
-I'll go home with mom and then I don't know if I'll go out tía- I said
-You should come eat with me, I'll be alone and I wanted to ask you to stay with me next week, Erika is going on a trip and I don't want to spend the week alone- she said
-Clearly yes aunt, I'll be here with you today at 3 and I'll ask permission to stay, I'm sure mom will say yes- I said
-Clearly yes, same as my sister, then we'll see each other around 3?- she said
-Clearly yes aunt, take care- I left her house and headed to university
Nothing relevant happened except a burned with a cautín and a good class, that's it.
In the afternoon around 3 I returned to my aunt's house and there they were, already with food ready and everything prepared.
-Hi Éyummy, aunt, what are we eating?- I asked
-Soup and a stew your aunt made- Erika said
We ate quietly, when we finished we prepared coffee and started talking
-Cousin, today you're invited to eat because we have something to ask you, it's Something serious and careful so we ask for discretion accepts or not said Sofia - you need Aunt Sofia, they know that can count on me for whatever- I said - look it's something serious-Ericka- because we as a couple feel that it's the moment to take another step in our relationship, in this case having a baby- said Ericka - I understand what you're saying Erika, but I don't see how I can help them-even though I imagined they wanted some kind of recommendation letter for adoption or something like that. - we think about adopting a baby, but due to our condition as lesbians, we believe it will be difficult- we think about a sperm donor, going to a bank, but that alternative is very expensive for us, so the alternative left is asking someone we know and have confidence in that they are a healthy and clean person, besides not getting tricked when giving the sperm- said Erika - so we thought of you, we had thought of your father, in a brother of Erick's but honestly it doesn't seem like the best candidates, besides they wouldn't understand and maybe get us into trouble- said Sofia - then the idea is that I would give my sperm and be in vitro?- asked - well that would be the difficult option, but honestly we were thinking about something else, but Sofia will explain on Monday morning, I have to go back to work and Sofia will pack my bags- said Erika - so we'll see each other aunt on Monday?- I said - of course yes, tomorrow I'll be all day with Ericka, so come until Monday- said Sofia
I bid them farewell with a kiss from both of them and went home to rest, I know now it sounds logical what they wanted but at that moment the truth was I was so impressed with what they had asked me that I couldn't even imagine it. That day passed, then Sunday and Monday morning I took my suitcase and headed to my aunt's house, arrived early, greeted, breakfasted and went to see TV, she came - well you'll wonder how we want that helps us- said
-if tía, the truth I haven't thought about how, the only one is in vitro and you've already said that's not it- said
-well, this is something very easy, are you a virgin?- asked
-well, the truth I'm not tía- said something sad despite having a lot of confidence with her
-well, I don't want your first time to be like we're going to do it- said
-what are you talking about?- said
-we're going to my bedroom- said and took me by the hand
-look, I've been reading a lot about the topic and it won't just take one time for us to get pregnant, we'll need to do it several times, maybe twice a day- he said and I was at a loss
-look, we're going to do this I have a skirt, I'll put it on without anything underneath, I'll lubricate myself, you'll lie back and while I'm making you come, when you're about to come, tell me and let me in- said as he took off his skirt
-I was thinking to myself that at least I would have the opportunity to be inside her, besides I'd get off with her hands.
-do you understand?- asked
-huh? Ah yes, I understood tía- said
-sofia, now I'm sofia, let's not make this any weirder than it already is- said
-well, take your pants down and lie back- ordered
-I did, I lay back with my flaccid cock and she started to caress it, for some reason she had trouble getting an erection.
-mmm this isn't working like I expected, let's see if this works. Said as he put my cock in his mouth and started sucking it, I don't know if he had experience or what was going on but he did it very well, my erection didn't take long to come and by the time I remembered I was already near climax
-sofia, I'm coming- said
-I took my cock out of his mouth and she got up on me, letting my cock enter her vagina, which felt so good entering her, but she was wet, not that lubricant wetness, more like a wetness and heat that only comes when you're excited. The problem was that when he put my cock in her vagina she just stopped moving, just stayed there doing nothing.
-what's going on because I didn't see you coming?- asked
-tía, I mean sofia, you need to move on top of me, it's not just about me coming, I need to feel movement - I said
- Seriously? The truth is that I don't have experience with men, only with women - she said
- When Erica comes over do you keep licking or putting your fingers in? - asked
- Yes, so she can feel better - responded
- Well it's the same with men we need stimulation to last - I said
- Then should I move? - asked
- Yes, move up and down slowly then increase the pace - I said
She started moving as I had explained her vagina was so tight I think she was almost a virgin her cheeks turned red she moaned slowly
- Brother never felt this before - she said while moving faster riding my cock like a madwoman I could feel that she was also close to orgasm so I let her feel like she had control I was there to help her not to screw her besides it was my aunt
- Sofia I'm coming I'm coming - I said releasing jets of semen inside her
- Ahhh ahhh - she moaned falling onto my chest her breathing agitated I knew she had also come
- Now what do we do? - asked after a few minutes with my cock still inside her
- Then get up - I said
- But won't your semen come out? - she said
- No Sofia get up and relax like that it will be harder for it to come out - I said
She reclined beside me still a little agitated but calm I got up to the bathroom to clean myself
- Oh don't tell Erica what happened she thinks you're only going to come inside me and then leave I didn't want this to happen - she said
- Sofia I won't say anything but now you know that like you thought it wouldn't work we have to do it this way it's fine? - asked making myself crazy of course it was fine she had enjoyed it and I planned to get the most out of this situation calculating that if I screwed her once more she would be begging for my cock like a madwoman of course I wasn't thinking about making her leave her partner
- I understand what you're saying you're right we have to do it this way if we want this to work - she said
- Okay - I said and went to take a bath She reached me -I'll take a bath with you and we'll do it again- she said. She put me in the showerhead and started to suck me so my cock would be ready, she took my hand away and did the same thing. -You know it's the first cock I've seen up close, it's big, I didn't imagine them like that, I thought they were dirty and had a bad smell- she said. -Well, you're wrong, turn around- I said. And started to put it in her slowly, this time I had control so I could give her the strongest orgasm of her life, to see how she would react, she was moaning and screaming -Wait, it's too fast, slower, if you keep going I'll... ahhhhh me coming- she moaned and screamed. I stopped before coming -Because you stop, keep going, you have to empty yourself inside- she said without realizing that I had stopped to take advantage of her even more -Wait, I'm tired a bit- I lied. I went at it again against her pussy, which was now a sea of delicious juices, soon she would beg for my cock and I could lick that tasty little thing -Ahhh ahhh I'm coming again- she said moaning. This time I came inside her, a bit less than the first time but abundant, she remained still, silent, finished my shower and lay down in the living room, she sat next to me -Am I not deceiving Erica, right?- she said and didn't give me time -I say it's enjoyable but it's part of having a baby- I said, keeping silence, that night she asked me to sleep with her, but instead of having sex she just slept wrapped around me. That's how my aunt discovered a new way to enjoy herself and learned to be unfaithful, soon I'll have more stories about her, thanks for reading and commenting.
