Absolutely time to return the favor

She was stripping off your shirt, pants and boxers so quickly that you barely could register that you were just as naked as she was. She shoved your clothes into the pile that had hers as she told you, “Alright, bro, on your tummy!” She could clearly see the erection you were sporting but you complied to her request. It was indeed uncomfortable as having your it was uncomfortable having your hardened dick squished into the hard sand. Your discomfort is eased quite a bit when you see your sister on your side with her tits hanging free and jiggling with every movement of lathering her hands with sunscreen.

Your back has a light sheen of sweat from the warm sun that felt nice when her hands rubbed in the lotion. You let out a light moan as it felt nice to have her hands massaging you as well as her tits jiggling all around. You would have thought this was heaven if the lingering uncomfortableness of your pulsating dick pushing into the unmovable sand. She must have caught on and said, “Roll over, bro! I can see your discomfort.”

You felt relieved as you turned to your side and your raging boner was pointing right at her. You looked at it and you have never been this hard before in your life. It took you a second to move as you sister was clearly eyeing it and licking her lips. You stayed in the position for what felt like forever until she said, “On your back so that we can finish you!” You lay on your back as she applies more sunscreen to her hands, causing the booby jiggling to start again. She starts with your chest and quickly moves it down to your abs. Her tits are dangling right in your face as she moves her hands down.

Suddenly she straddles you and you are in a 69 position with her. You don’t dare touch her oozing pussy lips until she touches your throbbing dick. She continues lathering down up your legs and finishing your feet. She moves her hands up slowly back up and keeps them just to the right and left of your erection. You can feel yourself dripping precum as you can feel her gaze just before her breath as she got her mouth closer. You could see just how juicy and shimmering her own pussy was as you wanted to taste her nectar so badly.

You could feel her tongue gently graze the tip of your cock when she stopped. She suddenly sit ups and hops down next to you. “Bro! Hurry! The towel!” She said with a sharp whisper. You quickly pull it out from under yourself and do your best to cover yours and her lower halves as she cuddles into your chest to hide her naked breasts. What did she see?
