Give the girl what she wants

Taking your sister’s word, more or less because your geyser is about to erupt and there is little hope of getting Megan off of you now more so than trusting she’s on the pill, you stop holding back you cum from her. The most amazing orgasm you have ever experienced transcends over you as you pump your sister’s needing cunt full hot warm seed. She continues pumping you dry, long after you have stopped cumming. She leans down and kisses you hard on the lips, “Thanks bro” she says, rising up off you, and laying her head on your shoulder as she snuggles in beside you. She drifts off to sleep quickly, but you are unable to fall asleep. There are too many things going on in your mind. About your sister, about the other girls on the hall, about Megan’s friends, about anticipating what tomorrow will bring. Damnit, you can’t just lie here in bed can you, with all those other cock needing women out there, but you need to stay here and hold your sister right? What do you do?
