She hugs him, holds him, as he holds her- kisses her, on the lips and down her neck. Nibbles a little, comments on something, causing her to giggle.
He says something else... she looks down, "Very few guys, past family members, have called me pretty..." She says it, regrets it, feels pathetic for letting him know that, for showing it means so much.
"Are they blind? You are very pretty." He tightens his grip on her, lifts her chin up with his hand. She has tears in her eyes, happy tears. He kisses her cheeks, both where a tear had been, then the lips, and they go on like this. Cuddling, talking, a little flirting...
Friends, but... with very sweet benefits?
