Rachel naked, masturbating

Rachel was flat on her back, her knees pulled up. One hand squeezed her tit and pinched her nipple, while the other rubbed her clit frantically. She hadn't heard us, and she was moaning, "Oh, Mike! Suck my tit!" Then Rachel surprised us both when she whispered, "Oh, my God, Ria, your tongue is soooo good!"

Ria's hand drifted up to cup her boob. I was so horny, I didn't know what to do, but my feet stepped forward, behind Ria. She turned her head a fraction and sniffed the air, then gave a slight moan. I caressed her shoulder and trailed my hand down to her unoccupied breast. She didn't stop me. I nibbled her neck as I squeezed her perky mound. I pressed my stiffness against her warm backside. She wiggled in front of me, her tight ass rubbing my bulge.

Ria whispered, "I don't know what's happening. My body feels on fire. Every touch sends the pleasure all over me."

Now Rachel was finger fucking herself with one hand and rapidly diddling her clit with the other. Her moans and whimpers covered our nearly silent voices.

I rubbed Ria's belly as I groped her and kissed her earlobe. pulling a moan from her throat. "I could make you feel what she's feeling," I said breathily into her ear. A shudder ran through her whole body.

I slipped my hand into Ria's jeans and found that she had indeed gone without panties. My fingers found her gushing wet slit easily. Ria stifled a shrill gasp with her hand. She grabbed my hand on her breast and moved it under her tight pink shirt. I found her bare tit and squeezed, rubbing my palm across her fat nipple.

At that moment, Rachel let out a loud, low groan that quickly ran up the scales until she was singing out her climax to the world. Rachel's body undulated and her legs closed and opened on her hands. Her breasts jiggled wildly through her orgasm. She called out, "Ria! I'm coming!"

I whispered, "Go to her, she wants you."

Ria moaned and quietly replied, "Only if you join us." She turned in my arm and gave me a lusty stare. Then she lifted her shirt over her head, revealing her naked teacup tits. Her fat nipples were as big as my fingertip. Her gorgeous brown skin looked so lovely. Then she turned and darted to the bed, dropping her tight jeans as she went. I watched my naked neighbor jump into bed with my naked masturbating sister.

Rachel gasped when Ria jumped on top of her. Ria smothered Rachel's mouth with hers and kissed her, her hands stroking Rachel's shoulders. The dichotomy of brown and pale skin, big jiggly breasts and little teacups, and red and brown hair made my cock twitch again.

Was I really going to have sex with both of them? Sure, I'd lusted for Ria a long time. I'd also spanked it every time I'd ever accidentally caught a glimpse of Rachel in the bathroom or shower. Plus a few times I had snuck in to peep at her.
