A sexual act involving
two males. The first male gently cups his testicles with one hand, while using the other to lift the penis so as to have a space between the
top of the scrotum and the underside of the the shaft of the penis. The second male then thrusts his hardened penis into this space. The first male releases his penis, creating a more tight space for the second penis to fill. The second male proceeds to fuck this space.
The first male
may always opt to squeeze his entire package in between his hands, so that the male
fucking the scrumdiddle
may receive more pleasure.
