“What’s wrong?” she asked me.“Cum. There’s cum in your mouth.”“So?”“So?” I repeated, stating what seemed obvious to me. “Ew. It�...�s cum. My cum. I don’t wanna taste my own cum.”“Why not?”I struggled to explain what bothered me. “It’s gross. It’s wrong. It’s like, gay.”She looked offended by my explanation.I said, “I don’t know. It’s just…ew.”“It wasn’t so ‘ew’ when I was sucking your cock.” She sounded offended. I didn’t know why. “It wasn’t wrong when you were cumming in my mouth.”I just looked. “Do you remember that first time with me?” she asked. “Do you want that?”“yes, … please.”“How I sat on your bed and reached under the sheets?”“uh huh.”“How I touched your little cock and made it hard?”“yeah.”“How I masturbated you? It was your birthday. You were so surprised.”“Uh huh.” I said. My cock was throbbing.“Are you hard right now?”“Yes.”“Remember how good my hand felt on your little penis? How wonderful my fingers made you feel?”“Uh huh,” she could hear my panting and she knew I was. She was giving moans. Those aroused me a lot. She said her legs are paining so I moved her to the bed. I can’t lift her.I then again started to suck her she started to moan again. I was not ready to leave. She said, “It’s not enough, give me more.” I understood what she needs. As she wished she I removed my shorts completely and took it near her pussy. She caught my penis with her hand and placed it near her pussy hole.I bent down to give her a kiss and entered in. She gave a loud moan. I. After sometime I put below her nightie and too my surprise she was not wearing any panty or bra and I put my hands on her milky boobs and pressed lightly at first and the evil in me didn’t satisfied and arched for something more and decided do sex with her then and there only and I forgot that she is my own sister only and woke up silently and pulled my shorts down and slept beside my sister and put my legs on her legs.She was breathing heavily and pressed the boobs heavily though she didnt.
