Almost caught air drying

You watched her as she gets up from her squatting position as she felt that she had pretty much had unloaded the majority of your semen from her anus. You were already laying down on one of the chaise lounges as you watch her looking between the empty one and the one you were already laying down on. “Scooch your booch, bro!” You were about to get up as you maybe thought she wanted that seat but you quickly realized she was wanting to get right next to you her ass engulfed your deflated cock.

You let out a moan as you could feel the blood coursing back through your nether regions as your erection was slowly building back to its engorged state. You heard her giggle as she squished her ass even more into your erection as you could let out a grunt of pleasure. “Are you feeling comfortable, sis?” You ask her as you thrust your hips a bit as you feel your precum lubricate between her ass cheeks. Now she was the one to be moaning as you both were pushing into one another.

“Oh yeah bro this…” she cut off what she was saying when she heard the door open.

“Hey honey! Are you out here?” You could hear your mom’s voice but it sounded like she was still on the other side of yard. If she comes outside she might have a heart attack to see the two children canoodling naked on one of the lounges.

“I’m all good, moms. Just trying…” Sis was cut off when you stuck your raging dick right back into her asshole.

“You alright honey? I’m coming out to check on you,” she said with a hint of concern in her voice. It was getting closer but you didn’t stop humping her asshole.

“Mom, it’s alright! Just a cramp but I’m all good. Don’t let me slow you down from doing your daily tasks,” she said with no problems as she was matching the speed of your humping.

“Alright honey. I’ll make sure I leave the door unlocked since I must have locked you out without realizing it,” she said. “I’ll be back soon if you need anything. Love you, sweetheart!”

“Love you too, mom,” she said as you heard the sliding door close and she let out moans of pleasure. “You almost got us in trouble, bro. But-t it was sooooo-uhhh fucking hot. Fuck me harder…” she said through her pleasure. You continued to thrust your dick into her asshole again as your grunts mixed with her moans. This continued for a few minutes until she wanted to switch positions. She had you on your back as she put her feet and hands down on the lounge. You felt like your dick was a piston ramming into her engine. You kept increasing the speed as she was practically screaming in pleasure. You were groaning quite loud yourself until she reached her orgasm and collapsed on you as you filled her up once again.

You both lay there as you also play with her tits that were rising and lowering with each tired breath that she took. She giggled as she rolled off of you and a flood of semen exited her asshole once again. “Holy shit, bro! I’m flooded again,” she said as she emptied her asshole for a second time in the past fifteen minutes. You watch as she squats once more and empties the semen from her asshole. She gets back up once more and lays next to you while snuggling back into to you. “That was incredible, bro…Thank you…” She said before quietly snoozing. You yawned yourself and you were not far behind her in your own nap. You two were in your own world as both of you were exhausted by your impromptu sexcapade.
