a lesbian is drinking with her male best friend at her place.
they start teasing each other and wrestling playfully, and then, as a joke, he bends her over across his lap and spanks her a few times, through clothes of course, as they both laugh about it.
they both get a strange feeling about it though. they've known each other for so long and have always felt comfortable with physical contact and doing silly things together; there was no reason for this to have crossed any line. there was no such intent behind it, of course. and yet here they are, in this position, still in a playful mood, still just good friends - she has a girlfriend, he's been talking to a girl he likes, they've never considered each other as anything resembling a potential date or hookup - but this strange feeling, hard to define, not nearly alarming enough to give either of them a pause, compells them to stay like this and keep going.
he gives her ass a few more firm slaps. she's laughing still, but it starts to kind of sound like moans, and she can feel blood rushing to her face, already flushed from the alcohol.
he keeps spanking her, hard, and she keeps whimpering and giggling about it, but they feel like this just isn't cutting it, not with the layers of fabric softening the blows. their inhibitions lowered, neither of them questions his next move - pulling her pants and underwear down, exposing her bare ass.
now, there's nothing to weaken the force of his open palm against her flesh. the next smack is loud and startles them both, and she squeals in pain and surprise. it leaves a red mark on her buttock.
still nothing to ruin their mood, though. it just seems like a good idea to keep doing this.
another smack, then another. there's a hardness growing in his pants despite the alcohol, but she barely notices that, or how the intense tingling sensation spreads through her entire body with each surge of pain. she can barely think, really, it all happens on impulse, that bond between them somehow making it all so innocuous still. all that matters is that it's just so fun and so silly. that it just hurts so good.
she clumsily slides her jeans and underwear down completely, kicks them away, then settles back on his lap as before, chuckling to herself. she's so tough, she's taking it so well! her ass is red and stinging, but she can take it, of course she can. and of course they should keep going.
even as the spanking that follows is relentless, accompanied by his gasps of exertion, each hit stinging more than the one before it. there are tears welling up in her eyes, which she's glad he can't see, though the whimpers she can't hold back are a dead giveaway what intense sensations she's experiencing.
she doesn't know if this is still funny, and it hurts so bad that it's hard for her to hold back the urge to just start sobbing; yet there is some strange simple comfort in knowing he will keep going until she physically gets away from him. and maybe even then he'll grab her and keep spanking her, though she's too dizzy to think that far ahead. right now, there is exists nothing else in this world but her humiliating position and the firm hand smacking her fat backside again and again and again and again.
so of course she doesn't notice until it's too late that all the shocks sent through her body from that sharp point of contact have been pooling in her as warm heavy tingling, not alleviated by her crying out but instead strengthened by it.
the pressure reaches its peak, her taut body spasms without warning, back arching and ass shooting upwards as her legs snap straight-
psssh....ssssquirtshhhh~...
her mind goes completely blank, pain and pleasure twist into one, and for what to her seems like an eternity she is stuck in this electrified ecstasy, orgasming violently while her cunt gushes like a hose all over the floor and her friend's legs.
the sound that leaves her drooling mouth would be embarrassing if she could tell where she was or who she was - a low, guttural moan, as if her braindead body's yelling out in surprise at being deprived of its control center.
she just came from being spanked. she didn't know that could happen, let alone that she could do it, let alone like this.
a few more spurts follow, a few aftershocks, before her legs give out, and she falls back onto her friend's lap.
for the next few moments, only her strained breathing can be heard. they don't have to say anything right now, though. they are both thinking the same thing.
he's going to smack her sore wobbly ass some more, he's going to force her to lick up the mess she's made, she's going to gladly take care of how riled up she's got him by letting him fuck her mouth until he cums down her throat, and then he's going to fingerfuck her greedy lesbian pussy until he's positive he's wrung out all the tearful dykegasms out of her.
