Twin Love - Parts 1, 2, & 3

... plump and lovely? &#034Psst, Libby...&#034 whispered Mark. &#034Are you sl**ping?&#034 Libby opened her eyes, facing her twin b*****r. &#034No,&#034 she whispered back. &#034Not really.&#034 Mark sat up. &#034Why don't you try sitting on me, like we saw Sheila doing downstairs?&#034 Libby's heart skipped a beat. She sat up and faced her b*****r in the shadowy darkness of their bedroom. Undeniably, she'd been thinking about what she'd seen as she tossed and turned next to Mark. What Sheila and Steve were doing was so strange, so curious, so alluring... Mark got up and silently walked to the bedroom door, taking Libby by the hand and leading her downstairs. They crept to the living room, where Mark sat down on the couch in the same spot Steve was in. He pulled Libby onto his lap. Her heart pounding fast, she let her b*****r hold her body tightly against him. Her crotch pressed hard into his and she gasped -- it was a surprising feeling, a feeling of pleasure she'd never felt before.

It's after midnight, you know!&#034 &#034Sorry mom!&#034 Libby shouted back. &#034We're coming back to bed now,&#034 Mark shouted. &#034Good night!&#034 &#034Good night, get some sl**p, k**s. Love you!&#034 Mark and Libby humped each other every night thereafter before they fell asl**p. Libby was soon experiencing orgasm after orgasm with her crotch pressed hard against her b*****r's, though she had no words for the intense feelings she was having. At first they rubbed against each other while wearing clothes, which was pleasurable enough. Then they began experimenting with grinding against each other whilst both were naked. Part 2 Once the twins began humping each naked, penetration was essentially inevitable. The first time Mark's small shaft sank into into his s****r's tight pussy was of course unintentional -- and incredible! Libby's gash had just been so particularly juicy on this occasion, as the twins had recently begun practicing kissing each other all over. Of course as Mark kissed his way down his s****r's body, he'd paid particular attention to her bald cunt mound and pink pussy flesh.
