Bonding with Big Sis

"Cum for me." I ground out trying to hold back my seed until I felt her gripping me tighter.

Her shivering box walls tossing me over the edge as I came hard in her frame. My balls empting their entire batch of batter into her shuddering walls. I fold over her panting hard as her body slumped against the bed hard. Our breathing the only audible thing at this point. My eyes are closed tight as my cock shivers and spews its last jets of cum into her frame.

"Oh...My... God! I cannot believe we just did that." Her voice came out to me low and unconcerned.

"Your pussy, is so fucken tight." I murmur into her ear kissing the shell of her ear and licking at her neck.

"You are so bad." She scolded me with no heat in her words.

"I'm going to show you just how bad I can be over these next few days." I chuckled kissing her lips feeling her tongue sneak out and push into my mouth. I'm not sure how long we laid like that, but what I do know is, this is going to last way longer than just a weekend.
