It's impossible not to love this.  It's an amateur video, done with crappy equipment (probably a computer), but it's so clear that these two are not just having sex but making love.  His body just eclipses her so completely as he fucks her, his muscles rippling around her head as he protects her and goes in for a kiss.  It's what all lovemaking should be like.  Passionate, free, loving, and with muscles.
