You and your sister have been growing a lot closer over lockdown, and have gradually started noticing each other in a new way. You've even tried masturbating in front of each other before, and both agreed that it definitely beats doing it by yourself! Today your parents have just left the house to go do the grocery shopping, and your sister immediately runs to your room and asks if you'd be up for repeating the experience. You agree and the two of you quickly strip off and get down to it, chatting about how weird it's been being stuck inside together all this time, and about how it's been ages since you've been able to see your girlfriend. Your sister at first says that she knows you're only doing this with her because you don't have access to your girlfriend, and that's fine.. but after a bit she says she would be willing to carry on doing this occasionally even when you're back with your girlfriend! She compliments the size of your dick and asks you about whether the girls you fuck like it, and the two of you playfully tease each other until you're both cumming together!
