Off course we are real brother and sister and sudden...y things changed between us.After a week when we both were alone at home for an hour, I hugged Tina from behind kept my chin over her shoulder. Tina was blushing and her heart was beating heavily. Without saying a word I kissed her neck and turn her around to see Tina was closing her eyes. Took her chin in my hand kissed on her lips which turned. .. two... three...Then we both cry out as we burst together. And again. And again.I move again, grinding onto his cock, feeling the jet against the spot deep inside, each spurt from him bringing another clench from me. Or is it the clench first?

The Dr. then told me now the more uncomfortable procedure would have to be performed and for me.
