It was like a velvet vise. She was below me, and I swear, we never lost eye contact, not even to kiss. I think we were both so overwhelmed by the moment. I felt my cock rubbing against the tender spot on her upper cunt wall that I now realize is her g-spot. When she started to meet my thrusts, it was with ferocity, but still her eyes only showed love…until they quickly shut and I felt her cunt clamp down even tighter. She let out an almost unearthly moan, and suddenly began crying.
Thinking I’d hurt her, I slowed down.
“No, oh God, no, please don’t stop,” she said, “please cum inside me. I love you so much, and I want your cum inside me.”
When it happened, much like the first time I came in her ass, it felt like one long, powerful stream. But this time, my cum was bathing her sweet cunt with my promise of undying love, and she knew it. Afterwards we held each other for nearly an hour, with light kisses, and light dozing.
For years, I’d always wondered how we never got caught. Our mom, though she was pretty engaged with us, never seemed to know about how much my sister and I loved each other or how often we made love. It wasn’t until about a month after mom died suddenly, that my sister finally told me the truth. Our mother knew. She’d watched us the day my sister accepted my marriage proposal.
“Christ,” I thought. Mom saw us with my cock in her daughter’s ass and didn’t flip out? She and my sister talked about our relationship only a couple of times, and it was my mother who made sure my sister got on birth control all those years ago.
Most parents would’ve screamed like banshees about us, particularly after watching a their daughter with their son’s cock in her ass. But apparently, our mother seemed to have implicit trust that neither my sister, nor I, were forcing anything on the other. We were, simply in love.
Now we’ve been together twenty-some years as lovers. We live as husband and wife, but no one really knows much about our private life. We’re just another “couple on the corner.” We just happen to have vaguely similar looks.
