That's the kind of slutty sister every brother would let work his testicles. And this one probably accustomed her to these pranks a long time ago. At least that's what I would have done. She'd have to suck and spread her legs anyway, so why not with her own man? It's about time she got her ass printed, too, so she can date like a grown-up bitch. Or maybe she's still trying to keep her anal virginity for her husband.
It's unclear what worked better for the daughter, playing the guitar or playing with her father's dick. It turned out that daddy is not only a good music teacher, but also a good teacher of sex, because he did not refuse his daughter, and with great pleasure continued the initiated caresses. What happened was what happened. Irresponsible incest took place in different positions with maximum intensity of passion and emotion.
