20 year old sis in law
Seen a video on my sister in laws iPad of her boyfriend in the shower, I have a bigger penis from what I saw and she is very open about her sex with him. I.E, anal, what she likes, where he cums and what she wants to try. We are super close but lately maybe a little to close and I've asked her to go on a trip with me as my gf can't make it. I'm worried I'll say or try something I shouldn't.
I have an urge sometimes just totell her I've been thinking about her in ways I shouldn't. What should I do ?
