Your cock is bigger than you think it is, Ben.”“Yeah, we’ll see. I’m not so sure about doing that to him – and I’m no Alvin!”She sobered... “No, you’re not; very few men could compare, but you’re plenty big. You’re sure that wasn’t hurtful to you, to see how I came on him? How powerful it was for me? I didn’t mean to hurt you or wound your masculine pride.”“No, not hurtful.

But I couldn’t help myself. I tickled Lynn’s back like no mother ever would.

I was so tempted to wander my dick in that bush and immediately removed my pant and underwear and slowly crept over her body.I slept over her and put my dick approximately into her bush and my dick stuck in her pussy hole straight away. I pushed it in slowly and she started to moan mmmmm ahhhh. I realised she being a previous generation woman would not be used to rough sex. So I thought not to fuck her too hard. I slept over her balloon like boobs and started penetrating deeper into her pussy..
