Get back in there of course!

You can go exploring later. Right now there are two hotties making out and stripping each other just yards away from you, and you're eager to get back to them.

Turning on your heel, you take the handful of steps and open the door to the home gym. You're greeted by the lovely sight of two naked girls going at it. June is lying on her back on one of the yoga mats, and Sarah is just sitting down on her face. Your sister sees you looking from the doorway and blushes. Her hands twitch as if to cover her privates, but she keeps them at her sides and smiles at you instead. "Get in here and close the door, Ryan."

You do exactly that and approach Sarah as June starts to eat her out from below. "Room for one more or would you rather I just watch?"

Sarah whimpers as she shifts around on June's face. "Do you still want that blowjob?"

Your already hard cock swells a little more when your sister asks you that. "Hell yes I do."

"Then whip it, mmh, whip it out already!"

Laughing, you open your pants and step a little closer before pulling your dick out. Sarah gingerly grasps it with both hands and slowly massages it as she works up the courage to blow you. She's intensely aware of June peeking up between her legs and that the rich girl thinks you're her boyfriend, not her brother. So, trying to act like she's done this before, Sarah pulls you closer and touches her tongue to your dick. She gives it a long exploratory lick, dragging her tongue around its tip and along the side until she reaches her hand. Then she licks her way back to the tip and opens wide to take you into her mouth.

There's no denying that your sister is inexperienced, at least where penises are concerned. You know you're not the first guy she's been with, but her preference is pussy. Still, after some initial clumsiness she gets into a groove and gives you a fairly decent blowjob. The fact that she's getting her carpet munched helps, the more turned on Sarah gets the more enthusiasm she puts into sucking your cock. Your mushroom head makes it into her throat several times, though it never stays there long before Sarah's gag reflex kicks in.

You kind of want to tell your sister to take it easy, but the way her throat constricts before it pushes you out feels amazing. She doesn't look like she's in pain and she's not complaining either, so you decide to just enjoy what she's doing and talk to your mom about teaching her how to deepthroat later.

That gets your imagination going and you picture Elsie and your sister teaming up to give you a twin blowjob. A moan from beneath Sarah prompts you to add June to the fantasy, jilling off through a pair of transparent yoga pants as she watches. Then you add Kelly for good measure, crawling on all fours with a big pregnant belly and full, leaky tits hanging almost to the ground as she looks at you pathetically.

You abruptly pull out and stroke your cock until you cum all over Sarah's front, dousing her face, tits, and tummy with semen. Sarah yells in surprise, then again louder as the feeling of your cum on her skin and June's talented tongue push her over the edge to her own climax.

After it's done Sarah just sits there for a while, until she notices your seed is dripping down her body. She hurries to stand and clean herself up, but June follows her up and starts licking your cum off her skin. Your sister freezes as she doesn't know how to react, but then decides to just go with it. Grabbing June's head, she guides her along to make sure she gets everything and catches each drop before it falls.

When June has worked her way halfway up Sarah's body, she grabs her boobs and latches on. Watching her suck on your sister's nipples is almost enough to make you hard again, but you're spent for now. It's still hot as hell though, so you make yourself comfortable and watch her go at it.

Sooner than you'd like, Sarah dislodges June's mouth from her breasts and makes her get back to licking your cum off her skin. It's just as well though, because not long after June has cleaned Sarah's face and moved on to making out with her there's a buzz to announce someone is at the main gate.
