My girlfriend’s sister has been after me for some time. But with each passing day she’s getting more and more aggressive with how she tries to tempt me. To seduce me. My girlfriend is in her mid-twenties, but her teenage sister lives with her, and it makes it a challenge.

“Come on. I know my sister is an old prude… I bet you’ve never even seen her pussy, let alone tasted her. I’ll let you do whatever you want with me.” She started to lift her shirt. I could see her taught tummy… she wasn’t wearing a bra. She never did. Her nipples were poking out...I knew if I saw them I’d be lost.

I tried to look down, and her hand was pulling on her short shorts. The top two buttons were undone, and it looked like she wasn’t wearing panties. She pulled a little more, and the third button was about to give way.

It was so tempting seeing that teenage pussy of hers. Those tight firm tits. She had a reputation, and I’m sure she would be tons of fun, and never push me away like her sister…

But it was her sister that I loved. That I was who I was waiting for. I ran past her to my girlfriends room.

She always asks what’s up, and I play it off. I don’t want the two of them to fight. Family is important and I didn’t want to get between them, but I couldn’t any longer. Not today, I had to tell her.

“I think your sister has a thing for me,” I told her hesitantly, “but I want to be with you.”

“Is she tempting you…?”

“Yes. But I’m here. With you.” I smiled. I noticed the coat she was wearing. “Are you wanting to go out today?”

“Tell me.. Did you see anything, of her? Did you want to?”

“I only have eyes for you. I ran to your room.”

She turned and started to open her coat. “I’m glad you came here instead of giving into my sister.” As the coat opened, I saw she wasn’t wearing anything under it.

I saw my girlfriend’s naked body for the first time. Her nipples were hard as rocks. Her pussy, as smooth as a baby. My mouth fell open.

“I know I’ve been a bit…hesitant. I wanted to make sure we were right for one another…and I know how much my sister can be a tease…” The coat fell to the ground. She was left only wearing high heels. “That’s why I feel comfortable enough to give you all of me.”

She walked up to me and kissed me. She pushed me on the bed and straddled me. I stared up at her naked body.

“Some of my past boyfriends couldn’t wait… that’s not what I want. I want someone who wants me, not just a quick fuck.”

“Fuck me,” I whispered.

“Oh, I intend to.”
