Never found an SP that can roleplay as well as my missus. She is great at “being” the character, all SP’s I’ve seen are good at playing the role, but it’s clearly “playing the role”.
Anal is better with my partner, she’s very tight, I’ve tended to find that SP’s who provide/like anal have had it so much that they feel less tight, and there’s all the faffing with condoms (rightly so).
When my missus is in the right mood she can also squirt better than I’ve seen, but this is quite rare.
