First time with stepson

It was a holiday weekend and we went to the house of my stepson Sergio and my lovely daughter-in-law Ana. Until then I had only given the kitchen to my cousin in childhood and to my wife, already some years ago. It was a hot day and we were in the pool enjoying the sun and some snacks. After a while I went to the bathroom to take a shower and remove the sunscreen from my body. The girls and Segio were still in the pool, but a little later I hear the bathroom door open and Sergio was asking... - So Paulo, is it over, I want to bathe and shave? - I'm finishing, will you shave while I'm gone? - Yeah, but do I shave in the shower? - Oh, so you come in and shave while I finish washing my head? Sergio got undressed, and I heard the door of the booth open, and I was standing with my back to the door, and I had shampoo on my head, and I took the shampoo off, and I looked back, and Sergio was naked, and he was staring at my hairy little butt, and the little sunspot from when I was tanning in my delta-wing bikini. - Our Paul? what a beautiful ass you have? is it smoother and rounder than Ana's? and that little mark there? I looked from the side and saw your cock hardening. Mole, he was already a nice, fat, not too big stick with a pink rosary. - I loved that little bundle. I couldn't resist the urge to watch his cock harden and I settled down in the stall to finish rinsing myself off and ended up resting my ass on his cock. - Be careful, Paul, or he'll come in. - Oops, I'm sorry, but if he wants to come in... I gave him a little spike in the little bundle and pushed more on his dick... At that time, Sergio hesitated a little, but the erection was already big, so he grabbed my waist and squeezed me against him. I felt his dick come in, the pink head knocked on the door of my donut asking for passage and a little bit of soap trickling down my back helped that pink head explore my ass. The head came in soft and gave a groan of horny, but Sergio did not restrain.... - Fuck, what a delight of cooking? bitch that gave birth, my head went soft, look at that, there's a hard-on, take Paul, swallow the rest... Sergio with a hard-on, squeezed a little more and his thick dick went all in and I felt his belly leaning on me. Sergio, go fuck yourself all over me. Sergio started to groan and give me soft punches making the stick go in and out almost all the way, then, with a hard-on, I started to roll on that stick stuck in me. - Hummmm... delight... take my hard-on, I'm going to roll on your dick... shove it all shove it... Sergio sounded hot and slapped my ass softly as his dick went in and out hot. My pinto hardened and Sergio could not contain himself and leaned on my back, struck his stick and began to punch a fist on my pinto that fit hard in his hand. - Delicious chicken and pork you have Paul, tell me, I'm not the first, who else eats this delicious bundle... - Aiiii... you see... no Sergio, just your mother and for some time now... stick, of flesh, you're the first since childhood when I gave for my cousin... - Shit, so that's why your ass is soft and cracked, it's the mommy that eats it every day....delicia...you're her little whore? - I am. I wear her panties and her bikini. - Ah, so the little mark in that delicious little bundle... takes my hard-on, takes... Sergio sounded nice while I was playing on his hand, but it wasn't long before he was saying... I'm going to fuck you up. Sergio increased his punches and I felt his dick swelling inside me and soon after the hot jet of his fun flooded my bundle he took the stick out of my ass and the shower water refreshed my broken bundle... - Ummmm, delicious Sergio, did you like my treat? - I love that little round ass of yours. We finished washing, but before we left, I still punched that stick and sucked it long enough for it to laugh in my face. We left the bathroom and went to the living room, where we found the girls. I stood up for a while, because my doughnut was still throbbing with a hard-on. The weekend was over, but not buried in my kitchen that Sergio continues to give to this day, when we are alone.
