Son falls for Lesbian mom's girlfriend/wife

[Strangebuddy]

Not an original idea but a few changes to an old one:

Instead of son going after his dad's wife or girlfriend, it's his mom's.

So for this case, mom had a son while she was in the closet. When she came out she and her husband got a divorce and son either went to live with her or spends time with both parents.

In either case, mom starts bringing around a new girlfriend who is just her son's type. Son tries to be respectful but can't help occasionally letting his eyes linger. What doesn't help matters is that she playfully flirts with him and admits that if she wasn't serious about his mom, she'd probably snatch him up like the cougar she is.

Still, son loves his mom and couldn't possibly try seducing her girlfriend/fiancé...could he?

For extra fun, maybe mom is already married or the wedding is right around the corner. New bride is starting to get a little tense about giving up guys completely and settling down so she actually comes on to son in hopes of getting some last second urges out or even sabotaging the wedding.

Does son succumb? Or does he decide to be the one to betray his mom's trust?

...or could mom even be somewhat open to the idea? (Maybe mom would like to have another kid and her son getting her girlfriend/wife pregnant is the closest thing to doing it herself).

I like all those twists.

I would have both the "fiance" and the son being attracted to each other, but trying to resist. Until right before the wedding, when the attraction turns out to be "bigger than the both of them" and they fall madly in bed with each other.

Mommy Dearest catches them (maybe not that first time; possibly a few weeks later as they continue their clandestine affair after the wedding) but she is totally into it. They have elaborate FMF sex, luridly described by the author. The son-impregnates-mom's-wife is the icing on the cake. I can envision the son lustily fucking the wife with her legs in the air, while Mom massages/licks his balls to ensure maximum potency.

Nice Twist! Love the thought of him being the gene donor of his mom's wife's child.

I love the premise of a young son falling for his mom's lesbian lover.

Maybe a domineering mom likes the idea of having a girlfriend to tease and control her son with? Maybe she could give both of them a good spanking for their being flirtatious with each other? I think many a naughty boy would love being house boy for his hot mom and her lesbian lover.
