[This was a custom request] Your younger, college aged sister is having a sleepover with her friends before they all head their separate ways. She heads into your room, giggling and woozy, to explain that all of her friends have been talking about you. Turns out, they all have a bit of a thing for you and, although your sister is embarrassed to explain, they have been talking about having you impregnate them all one by one. Wanting to please her friends, your sister asks if you'd be willing to do it. It's the last time you'll likely see them (or them, each other) so it's the perfect opportunity. You have a girlfriend but your sister promises to keep the secret between you and her friends. One by one, you spend alone time with each of the girls. First you meet Tammy, a cheerleader the same age as your sister who is very confident and flirty. She admits that this was all her idea and that she's been wanting to fuck you for a long time - being your sister's longest friend. She knows you're weak for perfect spread arses, so she teases you with hers. Her arsehole looks perfect. She has been sent in first as she knows she will be able to make you cum the quickest... and when your balls slap against her soaking wet pussy as you plough into her - you find that to be true. You empty inside her doggystyle and send her, ecstatic, out of the room. Next you meet Cherylene. She's a few years older than your sister and a gym girl. She's wearing gym shorts and a sports bra... She's not as outgoing as Tammy but she charms you immediately, telling you that she's the filthiest of them all. She proves it by immediately cleaning her friend's pussy juice from your cock with her mouth. She's also heard of your fetish and holds her sweaty gym shorts and panties to your nose to sniff. She smells divine. She spreads her legs for you and matches your strokes as you plunge into her. You fill her to the brim with your cum but, before leaving, she uses it to masturbate her asshole and pussy at the same time and shudder to an orgasm. She wants you to be hard again for her good friend, Zoe... Zoe is a nerd. She's in an oversized Harley Quinn t-shirt with matching panties and huge, thick rimmed glasses. She's visibly nervous but you can tell she has a naughty side. She giggles as she explains that she's only had sex once before with her boyfriend. You make her suck your cock clean and you promise to be gentle. She's surprised by the size of your cock - it's much bigger than her boyfriends was. Although you're stretching her, you can tell that you're making her feel good and eventually she cries out with pleasure as she cums around your massive cock. You fill her up too while her walls contract around you... and all she can do is whimper her thanks with rosy cheeks. The final girl, Claire, is a religious nut. She doesn't want to be here but the other girl's have convinced her. At first, she won't even remove her hands from covering her underwear but you slowly convince her to open up until she slips out of her bra. She has lovely perky tits but you want to see her arse. She bends over but her underwear is just plain white cotton and boring... she apologises, explaining that her Mum won't let her wear anything nicer. You convince her to remove it and get a peek of her pussy. You can't help but to push your hard cock in, despite her reluctance. She is so tight that you know straight away that she's a virgin. She admits that she is but soon she's moaning as your cock slips in and out of her. She's never felt anything so good. She kisses the crucifix around her neck and apologies to her God as you teach her the meaning of sexual pleasure. You shoot one more load into her womb too and leave her worried about how she's going to explain this to her Mother. Your sister finally returns, over the moon that you've decided to help out all of her friends with their kinky bucket list. But you still have one more thing that you want to do. Fucking all of these hot little college girls has made you feel limitless... and you've always have an deep, dark desire to taste your sister's tight flower. You encourage her to let you fuck her to complete the evening. She's disturbed by your request but you've helped to make her friends happy... and when she tastes all of their cum on your cock, she can't help but to feel a little intrigued. She asks for your final reassurance as she takes off her pyjamas - you've never been so sure. You spread her legs and push into her... it feels so strange to be doing it at first but you both find your rhythm. Your sister moans for you to fuck her harder and asks if her pussy feels better than all of her friends' did. It does... it is so wrong that your cock is pulsating inside her. You barely have any cum left in your balls but your sister's begging pulls one more massive load out of you. The biggest one yet...
