I'll start with a finger, then, when you're ready I'll put it in, okay?" Brian asked and Beth mumbled her approval. He brought the bottle of lube next...to his sister's ass, spread it open with one hand, then squeezed some onto her hole. He tossed the bottle aside, then used his index finger and started rubbing it into her ass hole.Beth let out a little moan as her big brother started rubbing the lube along her virgin hole. He teased it with his slick finger, rubbing around, then gently slipped. I could see in her eyes that he was going for her ass, as she somewhat tensed up then closed her eyes.I could tell when he made full penetration as his cock felt like it touched mine through her. Nobody moved for a moment, then I felt her pussy start to go up and down on me. He started to pump in and out of her ass and I just laid there feeling it all. She would go up and down rapidly a few times then slow down. He kept pace with her and I could hear him drawing in his breaths. She began. Finally, Neha got into her bathrobe and headed next door to the bathroom for, presumably, the shower. We had each just turned 18, and this was the most exciting thing ever to happen to us. And that ended our show for the day.As John lived a few streets down and it was tradition that whoever lost the game would have to walk the other person back to his house (unless of course the game took place at the winner's house). Seeing as I had lost I began walking John back."Raja, can I ask you. While she pressed her ass against my face. Her anus stretched a bit more. I removed my tongue and grabbed the bottle of lube. I put some of it one her ass and led it run inside of her."Uh that's cold."I put some on my middle finger and fingered her ass to fill it with the lube. Once her ass was lubed up enough i took the butt plug and inserted it slowly in her ass."AH! That hurts.", she said with a painful expression on her face. I lied down on the bed and put her on me. We were pleasuring each.
