Your bedroom

You open your bedroom door and are assaulted by the thick smell of sex. A shudder runs through you at the scent. You breathe through your mouth and try your best to ignore the thoughts that the smell provokes.

First you do your best to clean up the evidence. You crack a window and spray some deodorizer to try to get rid of the smell. You pick up the clothes you had grabbed earlier from your sister's room. The sweats are more or less okay, but there's no way you can put back the boyshorts. They are soaked through at the crotch with your juices and Alex's pre-cum, still a little warm from earlier. You try to ignore it as best you can, taking them to the bathroom to give a quick scrub in the sink and dry them off with a towel. Heading back to your room, you grab a duffel bag and toss them inside; you'll have to wash them properly at Alex's place. After a second's thought you toss in the sweats as well. You should probably get another pair or two of underwear while you're at it, but that can wait.

You go to the bed to pull off the stained sheets. As you do, you hear a clattering sound as something drops to the floor. You look down to see what it was.

A dildo. Your dildo. Your breath is a little shaky and you can practically feel your pulse between your legs. You rub them together in a vain attempt to bring some relief before you reach down to pick it up...and put it in the duffel bag. As badly as you want something inside you right now, you know that if you start playing with yourself you won't be able to leave the house. Eager to get out of here, you throw the sheets in the hamper and scamper out of the room, bag over your shoulder.

Once more you head into your sister's room. You've been in and out of her enough times today that by this point you barely even feel like you are trespassing. You head to your sister's dresser, poking through it for something to wear tomorrow. You are careful to leave everything as it was, grabbing only a single pair of underwear. You've already taken a lot of clothes as well as her masturbation tool; if you don't take any more, she might just think she misplaced them. Why you needed to steal some of her underwear is a conversation that you really don't want to have. As you start to close the drawers, you notice something towards the bottom. Your eyebrows shoot up in surprise, pulling out the piece of clothing to double-check if it is what you think it is. It is.

Damn Gwen, I didn't think you were into this sort of thing. You smirk a bit in amusement before a thought runs through your head. Your eyes dart in the direction of the kitchen and you bite your bottom lip. It's a risk to take something so distinctive. Gwen will almost certainly notice it's missing. But your judgment is clouded enough by arousal that the thought of Alex's expression when he sees you wearing this makes you think it's worth the risk. You close the drawer and toss the clothing on the bed. You think you remember seeing some other stuff in Gwen's room that would go with it; a quick raid has you carefully folding your acquisitions in the baggy gray sweats and hiding them in the bottom of the duffel bag. You toss the bag over your shoulder and head back to the kitchen.
