Give her a moment

You silently watch Vanessa return to planet earth from her orgasmic high. Her eyes focus again and she looks you deep in the eyes. "Ready to begin?" you ask her. She laughs. "Boy, you just ended me and you say it's just starting?" she says. "Of course I'm ready. Fuck me up, Scotty." she says. You crawl your way higher on the bed such that you're dick is lined up with Vanessa's cunt and your mouths on each other.

You kiss passionately as you enter Vanessa. With a slow pace you start pushing in and out of Vanessa's surprisingly tight snatch. Men these days must be on the small side, you think to yourself. Your tongues find a natural rhythm and you continue your love making, forgetting about time or location. About taboos or strange rules. About being the chosen one to save the world by fucking and impregnating as many women as you can.

At some point the lust that has been building up inside of you gets the upper hand and you increase your pace. You try to find a better position and angle while still keeping your lips locked onto each other. Vanessa starts moaning into your mouth as you continue your kiss. You end up breaking the kiss, panting for breath to keep up the pace you have set for yourself. You stop for a moment to turn her around and with Vanessa now on all fours you continue pistoning in and out of her.

You sense you won't be able to refrain from releasing your cum inside of her and as if she can read your mind Vanessa assures you to cum deep inside of her. "Don't even... Ugh... think of pulling out. Oh fuuuck yes... Whatever... you were taught in school about... That's the spot... using condoms or... pulling out. It doesn't apply here. Just cum as deep inside me as you can. I want to feel my belly swell with the amount of hot fucking cum you're pumping into me. Oooooh, I... I'm cumming again!" Vanessa yells and at the same time as you feel Vanessa's pussy convulsing around your dick you push yourself as far and deep into her as you can and open the floodgates.

You're pretty sure Vanessa is getting her wish as you feel load after massive load of cum leave your balls and enter Vanessa's unprotected womb. Heavily panting you both wait, taking in the situation and letting the absolute metric shit ton of cum you just pumped into her reach all corners of your lover's insides.

You then hear another sound in the room. It sounds like sloshing water and you make out faint moans. Being careful not to take your dick out of Vanessa you turn your head in the corner of the room you see a figure sitting on the ground. She is furiously fingering herself, trying not to moan too loudly. As she reaches her orgasm she can't keep quiet and moans loudly. She's gushing a watery liquid from her pussy, her fingers still rubbing her clit. After recovering from her orgasm she finally notices the room is no longer filled with the slapping of flesh against flesh or Vanessa's moans to overpower her own.

She looks up and gasps as she looks up and your eyes lock. You can't help but gasp yourself as you see who the uninvited spectator is, because sitting in the corner with her hands still hidden deep inside her snatch and her eyes wide open, frozen like a deer in headlights, is Amelia.

"Amelia?" You say. Amelia pulls her fingers out of herself and gets up. She quickly falls back down however, not fully recovered from what seemed like a pretty powerful orgasm.

You pull your dick out of Vanessa and she quickly puts a hand over her pussy to keep any cum from leaking out. "This is all mine now." you hear her mutter. With your dick coated in a thin layer of cum you get off the bed and walk up to Amelia, who had fallen front first and is trying to push herself off the ground.

"What were you doing, sitting there in the corner? Why didn't you tell us you had arrived?" you ask her while positioning one foot on either side of her and pulling her up. You pull her up completely and keep her from falling over by wrapping your arms around her.

Your dick however seems to have found a hidden bit of extra energy and you're rapidly growing another erection. With Amelia's bottom just as uncovered as yours it isn't long before you dick touches Amelia's soft pussy lips. Amelia moans softly.

"Were you turned on from watching me fuck Vanessa? Is that why you sat in the corner fingering yourself?" you say softly, unaccusingly. And then it hits you. "Were you imagining it was you who I was fucking and not Vanessa?" you ask her. Amelia nods and you feel her whole body tremble in your arms as she weeps silently. From shame, or maybe from sadness that is was in fact Vanessa and not her.

"Amelia. Tell me honestly, please. Do you want to have sex with me?" you say after turning her around to look her in the eyes. You wait in silence for a response. Slowly, Amelia nods. "Yes, but we can't. And that is frustrating and feels unfair. Yes, I would love nothing more than to be fucked by my little brother. There, I said it."

You think for a moment. "If you want it so badly, what is stopping you from doing it? I don't think taboos really apply here anymore." you tell her. Amelia shakes her head. "You know it's wrong, but you would do it to make me happy?" she asks unbelieving of what you're proposing.
