She walked past my bed and put my clothes away in my closet and while she did that, I grabbed my underwearand pants and put them back on. She just gla...ced over at me and smiled but on her way back out, she mentioned that my cock looked just like my dad's! That kinda got me wondering if she had actually seen my dad's cock or if she meant when he was a young boy or something.That Friday evening, around 8 or so, I was up in my room listening to some music and generally doing nothing. It was. I said but the baby can’t suck. FIL said I know, you will have to replace the baby with some one else. I asked who? He said who else than me, provided you agree. I felt shy and went red in face, but there was no other way out. I agreed and my FIL slept with his head on my lap. I switched off the lamp because of my shyness. My FIL then started tonguing my nipples lightly and then started sucking the milk out of my boobs. I thought he would spit it out but he started drinking the milk as he. We explored each other’s tongue and my hands were wandering over her curves. And they were smooth like silk and I could just glide my hands over them.Then she pulled up my t-shirt and I did hers. And there they were, in their absolute glory! HER TITS!! I couldn’t stop myself from grabbing them.She let out a moan as soon as I grabbed those and I could see the change in her facial expressions. I couldn’t wait and unhooked the bra and freed those from their prison only to be caught by my mouth. I. She kept staring at my penis in anticipation. For a moment, I got really scared that if I failed to get it up, Rina would refuse to get married.“It seems you are still shy. Don’t worry, it will eventually come up,” she said and kissed me again, making me forget about my problem. I didn’t get a hard-on that night.I don’t know if it was performance pressure or what. Because I was able to masturbate later in my bedroom while watching naked selfies of Rina. Since then, we have tried several times.
