A visitor

The patio door opens behind you and your mom looks up. "Ah, Alex! Perfect timing." Turning around you see your previously younger brother stepping outside. "Jane here just said how she would love to practice giving a blowjob." You snap your head back around and stare her disbelievingly in the eyes. She didn't just say that, did she? But to you utter surprise and slight horror your brother follows her suggestion without questioning and just like that steps in front of you with his dick out.

"Impressive, isn't it." your mom purposefully misinterprets your shocked look. "The big dick genes have been passed on by your father. Well, to anyone but your old self. You were always rather pathetic in that department. Anyway, be a good little slut-sister and start sucking now." "MOM! NO!", embarrassment and a bit of disgust wash over you, but she just takes your brothers massive cock and points it at your face. “Open wide!”

"Oh, don't tell me that you are not the slightest bit curious. Just open your mouth, I promise you'll like the taste!"

Hesitantly and guided by her firm hand you lean in and obey her instructions despite wanting to run away from this situation. When your lips make contact with his crown you take a deep breath and feel yourself getting intoxicated by his manly smell and taste. Suddenly your perception shifts a slight bit, and your struggle creases as you start to get into it.

Slowly with rotating movements you begin your first blowjob. By imagining what you think would have felt nice on your old dick, you work your brothers cock deeper and deeper into your previously virgin mouth, slowly getting to like the taste. Next to you, your mom is sitting with a satisfied grin. She already knows that this won't be the only dick you will be sucking.
