They wanted a baby, my sister is lesbian, older than me by two years. We’ve never hid ourselves from one another. They wanted a baby and me to do it
My sister approached me when I was 22 she was 24. I’d not had a steady girlfriend for a year or so, she sat me down and asked me for my help. Of course I’d do anything for her I told her, and she said this was different, that most requests. She and Tess her lesbian wife, want a baby. Tess was 5ft. 8in tall weighed 115lbs, great body, beautiful legs, ass, and was incredibly pretty. Kay my sis was 5ft. 7in, weight 135, mostly muscle, with almost no tits at all vs. Tess’ D cups. They didn’t want to pay a sperm bank, nor go through in-vitro and wanted to abandon all the expense. Kay knew I never wanted to have kids, but asked if I would have sex with her and Tess and get her pregnant. I had to have a definition of have sex with them both. After all I only needed to have sex with Tess to get her pregnant.
The thought was that it would be very weird, or I should say even weirder than it was, if I were to have full on sex with her. She was a lesbian and didn’t like sex with guys. The “operation” would be that my sis and tess would have sex, I’d be with them, they’d both be using their hands on me, and Kay would then prop up Kays hips, insert a plastic speculum and open her vagina. Then she’d use her hand and mouth on me to get me hard and I’d then finish with my hand and shoot directly into Tess opened pussy, then Kay would push it all down onto her cervix and close the speculum. Tess would wait for 20 minutes raised up like that and then relax.
Well, it was a bit more clinical than I wanted, Kay and I had oral and anal sex growing up a few times when we just couldn’t contain ourselves, so that wasn’t an issue. I really wanted to fuck Tess though, she’s gorgeous. So we did it their way all during her fertile time and nothing. Then again the next month, nothing. So finally Tess just said that it’s best she stays with me at my place and we have real sex and do it that way. Kay had an objection, honestly not my fucking Tess but rather her being with me for several days on our own. She said it had to be at their place. So, we did. Tess and I fucked, Kay watched once then was in the guest room while we did it. She always came back to their bedroom after. I stayed so I could have Tess again during the night if I was ready. I dumped as much cum into Tess as possible. The next month worked, She got pregnant.
So now my sister and her wife have a son, they want to try for a daughter.
